Expand description

Properties

`activate-on-single-click`

The “activate-on-single-click” property denotes if results should be activated simply by clicking on them. You may want to set this to false if you want the behavior to only select the item.

Readable | Writeable

`compact`

The “compact” property denotes if an alternate style should be used to reduce the width of the rows. This may be ideal in size contrained situations with portrait display.

Readable | Writeable

`suggestion`

The “suggestion” property is the currently selected suggestion, if any.

Readable | Writeable

Entry

`attributes`

A list of Pango attributes to apply to the text of the entry.

This is mainly useful to change the size or weight of the text.

The PangoAttribute’s start_index and end_index must refer to the [gtk::EntryBuffer][crate::gtk::EntryBuffer] text, i.e. without the preedit string.

Readable | Writeable

`caps-lock-warning`

Whether password entries will show a warning when Caps Lock is on.

Note that the warning is shown using a secondary icon, and thus does not work if you are using the secondary icon position for some other purpose.

Readable | Writeable

`completion`

The auxiliary completion object to use with the entry.

Readable | Writeable

`im-module`

Which IM (input method) module should be used for this entry. See GtkIMContext.

Setting this to a non-None value overrides the system-wide IM module setting. See the GtkSettings GtkSettings:gtk-im-module property.

Readable | Writeable

`inner-border`

Sets the text area’s border between the text and the frame.

Readable | Writeable

`input-hints`

Additional hints (beyond [input-purpose][struct@crate::gtk::Entry#input-purpose]) that allow input methods to fine-tune their behaviour.

Readable | Writeable

`input-purpose`

The purpose of this text field.

This property can be used by on-screen keyboards and other input methods to adjust their behaviour.

Note that setting the purpose to GTK_INPUT_PURPOSE_PASSWORD or GTK_INPUT_PURPOSE_PIN is independent from setting [visibility][struct@crate::gtk::Entry#visibility].

Readable | Writeable

The invisible character is used when masking entry contents (in "password mode")“). When it is not explicitly set with the [invisible-char][struct@crate::gtk::Entry#invisible-char] property, GTK+ determines the character to use from a list of possible candidates, depending on availability in the current font.

This style property allows the theme to prepend a character to the list of candidates.

Readable | Writeable

`invisible-char-set`

Whether the invisible char has been set for the [gtk::Entry][crate::gtk::Entry].

Readable | Writeable

`max-length`

Readable | Writeable

`max-width-chars`

The desired maximum width of the entry, in characters. If this property is set to -1, the width will be calculated automatically.

Readable | Writeable

`overwrite-mode`

If text is overwritten when typing in the [gtk::Entry][crate::gtk::Entry].

Readable | Writeable

`placeholder-text`

The text that will be displayed in the [gtk::Entry][crate::gtk::Entry] when it is empty and unfocused.

Readable | Writeable

If :populate-all is true, the [populate-popup][struct@crate::gtk::Entry#populate-popup] signal is also emitted for touch popups.

Readable | Writeable

`primary-icon-activatable`

Whether the primary icon is activatable.

GTK+ emits the [icon-press][struct@crate::gtk::Entry#icon-press] and [icon-release][struct@crate::gtk::Entry#icon-release] signals only on sensitive, activatable icons.

Sensitive, but non-activatable icons can be used for purely informational purposes.

Readable | Writeable

The icon name to use for the primary icon for the entry.

Readable | Writeable

`primary-icon-pixbuf`

A pixbuf to use as the primary icon for the entry.

Readable | Writeable

`primary-icon-sensitive`

Whether the primary icon is sensitive.

An insensitive icon appears grayed out. GTK+ does not emit the [icon-press][struct@crate::gtk::Entry#icon-press] and [icon-release][struct@crate::gtk::Entry#icon-release] signals and does not allow DND from insensitive icons.

An icon should be set insensitive if the action that would trigger when clicked is currently not available.

Readable | Writeable

`has-focus`

Readable | Writeable

Enables or disables the emission of [query-tooltip][struct@crate::gtk::Widget#query-tooltip] on widget. A value of true indicates that widget can have a tooltip, in this case the widget will be queried using [query-tooltip][struct@crate::gtk::Widget#query-tooltip] to determine whether it will provide a tooltip or not.

Note that setting this property to true for the first time will change the event masks of the GdkWindows of this widget to include leave-notify and motion-notify events. This cannot and will not be undone when the property is set to false again.

The style of the widget, which contains information about how it will look (colors, etc).

Readable | Writeable

Sets the text of tooltip to be the given string, which is marked up with the [Pango text markup language][PangoMarkupFormat]. Also see gtk_tooltip_set_markup().

This is a convenience property which will take care of getting the tooltip shown if the given string is not None: [has-tooltip][struct@crate::gtk::Widget#has-tooltip] will automatically be set to true and there will be taken care of [query-tooltip][struct@crate::gtk::Widget#query-tooltip] in the default signal handler.

Note that if both [tooltip-text][struct@crate::gtk::Widget#tooltip-text] and [tooltip-markup][struct@crate::gtk::Widget#tooltip-markup] are set, the last one wins.

Readable | Writeable

Sets the text of tooltip to be the given string.

Also see gtk_tooltip_set_text().

Signals

`action`

Action

`activate-suggestion`

Action

`hide-suggestions`

Action

`move-suggestion`

This moves the selected suggestion in the popover by the value provided. -1 moves up one row, 1, moves down a row.

Action

`show-suggestions`

Action

`suggestion-activated`

`suggestion-selected`

This signal is emitted when a selection has been specifically selected by the user, such as by clicking on the row or moving to the row with keyboard, such as with move-suggestion

Entry

`activate`

The ::activate signal is emitted when the user hits the Enter key.

While this signal is used as a [keybinding signal][GtkBindingSignal], it is also commonly used by applications to intercept activation of entries.

The default bindings for this signal are all forms of the Enter key.

Action

`backspace`

The ::backspace signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user asks for it.

The default bindings for this signal are Backspace and Shift-Backspace.

Action

`copy-clipboard`

The ::copy-clipboard signal is a [keybinding signal][GtkBindingSignal] which gets emitted to copy the selection to the clipboard.

The default bindings for this signal are Ctrl-c and Ctrl-Insert.

Action

`cut-clipboard`

The ::cut-clipboard signal is a [keybinding signal][GtkBindingSignal] which gets emitted to cut the selection to the clipboard.

The default bindings for this signal are Ctrl-x and Shift-Delete.

Action

`delete-from-cursor`

The ::delete-from-cursor signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user initiates a text deletion.

If the type_ is GTK_DELETE_CHARS, GTK+ deletes the selection if there is one, otherwise it deletes the requested number of characters.

The default bindings for this signal are Delete for deleting a character and Ctrl-Delete for deleting a word.

Action

`icon-press`

The ::icon-press signal is emitted when an activatable icon is clicked.

`icon-release`

The ::icon-release signal is emitted on the button release from a mouse click over an activatable icon.

`insert-at-cursor`

The ::insert-at-cursor signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user initiates the insertion of a fixed string at the cursor.

This signal has no default bindings.

Action

`insert-emoji`

The ::insert-emoji signal is a [keybinding signal][GtkBindingSignal] which gets emitted to present the Emoji chooser for the entry.

The default bindings for this signal are Ctrl-. and Ctrl-;

Action

`move-cursor`

The ::move-cursor signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user initiates a cursor movement. If the cursor is not visible in entry, this signal causes the viewport to be moved instead.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically.

The default bindings for this signal come in two variants, the variant with the Shift modifier extends the selection, the variant without the Shift modifer does not. There are too many key combinations to list them all here.

Arrow keys move by individual characters/lines
Ctrl-arrow key combinations move by words/paragraphs
Home/End keys move to the ends of the buffer

Action

`paste-clipboard`

The ::paste-clipboard signal is a [keybinding signal][GtkBindingSignal] which gets emitted to paste the contents of the clipboard into the text view.

The default bindings for this signal are Ctrl-v and Shift-Insert.

Action

The ::populate-popup signal gets emitted before showing the context menu of the entry.

If you need to add items to the context menu, connect to this signal and append your items to the widget, which will be a GtkMenu in this case.

If [populate-all][struct@crate::gtk::Entry#populate-all] is true, this signal will also be emitted to populate touch popups. In this case, widget will be a different container, e.g. a GtkToolbar. The signal handler should not make assumptions about the type of widget.

`preedit-changed`

If an input method is used, the typed text will not immediately be committed to the buffer. So if you are interested in the text, connect to this signal.

Action

`toggle-overwrite`

The ::toggle-overwrite signal is a [keybinding signal][GtkBindingSignal] which gets emitted to toggle the overwrite mode of the entry.

The default bindings for this signal is Insert.

Action

Widget

`accel-closures-changed`

`button-press-event`

The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_BUTTON_PRESS_MASK mask.

This signal will be sent to the grab widget if there is one.

`button-release-event`

The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_BUTTON_RELEASE_MASK mask.

This signal will be sent to the grab widget if there is one.

`can-activate-accel`

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This signal is present to allow applications and derived widgets to override the default [gtk::Widget][crate::gtk::Widget] handling for determining whether an accelerator can be activated.

`child-notify`

The ::child-notify signal is emitted for each [child property][child-properties] that has changed on an object. The signal’s detail holds the property name.

Detailed

`composited-changed`

The ::composited-changed signal is emitted when the composited status of widgets screen changes. See gdk_screen_is_composited().

Action

`configure-event`

The ::configure-event signal will be emitted when the size, position or stacking of the widget’s window has changed.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_STRUCTURE_MASK mask. GDK will enable this mask automatically for all new windows.

`damage-event`

Emitted when a redirected window belonging to widget gets drawn into. The region/area members of the event shows what area of the redirected drawable was drawn into.

`delete-event`

The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The default handler for this signal destroys the window. Connecting [WidgetExtManual::hide_on_delete()][crate::gtk::prelude::WidgetExtManual::hide_on_delete()] to this signal will cause the window to be hidden instead, so that it can later be shown again without reconstructing it.

`destroy`

Signals that all holders of a reference to the widget should release the reference that they hold. May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

`destroy-event`

The ::destroy-event signal is emitted when a GdkWindow is destroyed. You rarely get this signal, because most widgets disconnect themselves from their window before they destroy it, so no widget owns the window at destroy time.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_STRUCTURE_MASK mask. GDK will enable this mask automatically for all new windows.

`direction-changed`

The ::direction-changed signal is emitted when the text direction of a widget changes.

`drag-begin`

The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with e.g. [WidgetExtManual::drag_source_set_icon_pixbuf()][crate::gtk::prelude::WidgetExtManual::drag_source_set_icon_pixbuf()].

Note that some widgets set up a drag icon in the default handler of this signal, so you may have to use g_signal_connect_after() to override what the default handler did.

`drag-data-delete`

The ::drag-data-delete signal is emitted on the drag source when a drag with the action GDK_ACTION_MOVE is successfully completed. The signal handler is responsible for deleting the data that has been dropped. What “delete” means depends on the context of the drag operation.

`drag-data-get`

The ::drag-data-get signal is emitted on the drag source when the drop site requests the data which is dragged. It is the responsibility of the signal handler to fill data with the data in the format which is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text().

`drag-data-received`

The ::drag-data-received signal is emitted on the drop site when the dragged data has been received. If the data was received in order to determine whether the drop will be accepted, the handler is expected to call gdk_drag_status() and not finish the drag. If the data was received in response to a [drag-drop][struct@crate::gtk::Widget#drag-drop] signal (and this is the last target to be received), the handler for this signal is expected to process the received data and then call gtk_drag_finish(), setting the success parameter depending on whether the data was processed successfully.

Applications must create some means to determine why the signal was emitted and therefore whether to call gdk_drag_status() or gtk_drag_finish().

The handler may inspect the selected action with gdk_drag_context_get_selected_action() before calling gtk_drag_finish(), e.g. to implement GDK_ACTION_ASK as shown in the following example:

⚠️ The following code is in C ⚠️

void
drag_data_received (GtkWidget          *widget,
                    GdkDragContext     *context,
                    gint                x,
                    gint                y,
                    GtkSelectionData   *data,
                    guint               info,
                    guint               time)
{
  if ((data->length >= 0) && (data->format == 8))
    {
      GdkDragAction action;

      // handle data here

      action = gdk_drag_context_get_selected_action (context);
      if (action == GDK_ACTION_ASK)
        {
          GtkWidget *dialog;
          gint response;

          dialog = gtk_message_dialog_new (NULL,
                                           GTK_DIALOG_MODAL |
                                           GTK_DIALOG_DESTROY_WITH_PARENT,
                                           GTK_MESSAGE_INFO,
                                           GTK_BUTTONS_YES_NO,
                                           "Move the data ?\n");
          response = gtk_dialog_run (GTK_DIALOG (dialog));
          gtk_widget_destroy (dialog);

          if (response == GTK_RESPONSE_YES)
            action = GDK_ACTION_MOVE;
          else
            action = GDK_ACTION_COPY;
         }

      gtk_drag_finish (context, TRUE, action == GDK_ACTION_MOVE, time);
    }
  else
    gtk_drag_finish (context, FALSE, FALSE, time);
 }

`drag-drop`

The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns false and no further processing is necessary. Otherwise, the handler returns true. In this case, the handler must ensure that gtk_drag_finish() is called to let the source know that the drop is done. The call to gtk_drag_finish() can be done either directly or in a [drag-data-received][struct@crate::gtk::Widget#drag-data-received] handler which gets triggered by calling [WidgetExtManual::drag_get_data()][crate::gtk::prelude::WidgetExtManual::drag_get_data()] to receive the data for one or more of the supported targets.

`drag-end`

The ::drag-end signal is emitted on the drag source when a drag is finished. A typical reason to connect to this signal is to undo things done in [drag-begin][struct@crate::gtk::Widget#drag-begin].

`drag-failed`

The ::drag-failed signal is emitted on the drag source when a drag has failed. The signal handler may hook custom code to handle a failed DnD operation based on the type of error, it returns true is the failure has been already handled (not showing the default “drag operation failed” animation), otherwise it returns false.

`drag-leave`

The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. A typical reason to connect to this signal is to undo things done in [drag-motion][struct@crate::gtk::Widget#drag-motion], e.g. undo highlighting with [WidgetExtManual::drag_unhighlight()][crate::gtk::prelude::WidgetExtManual::drag_unhighlight()].

Likewise, the [drag-leave][struct@crate::gtk::Widget#drag-leave] signal is also emitted before the ::drag-drop signal, for instance to allow cleaning up of a preview item created in the [drag-motion][struct@crate::gtk::Widget#drag-motion] signal handler.

`drag-motion`

The ::drag-motion signal is emitted on the drop site when the user moves the cursor over the widget during a drag. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns false and no further processing is necessary. Otherwise, the handler returns true. In this case, the handler is responsible for providing the necessary information for displaying feedback to the user, by calling gdk_drag_status().

If the decision whether the drop will be accepted or rejected can’t be made based solely on the cursor position and the type of the data, the handler may inspect the dragged data by calling [WidgetExtManual::drag_get_data()][crate::gtk::prelude::WidgetExtManual::drag_get_data()] and defer the gdk_drag_status() call to the [drag-data-received][struct@crate::gtk::Widget#drag-data-received] handler. Note that you must pass GTK_DEST_DEFAULT_DROP, GTK_DEST_DEFAULT_MOTION or GTK_DEST_DEFAULT_ALL to [WidgetExtManual::drag_dest_set()][crate::gtk::prelude::WidgetExtManual::drag_dest_set()] when using the drag-motion signal that way.

Also note that there is no drag-enter signal. The drag receiver has to keep track of whether he has received any drag-motion signals since the last [drag-leave][struct@crate::gtk::Widget#drag-leave] and if not, treat the drag-motion signal as an “enter” signal. Upon an “enter”, the handler will typically highlight the drop site with [WidgetExtManual::drag_highlight()][crate::gtk::prelude::WidgetExtManual::drag_highlight()].

                    gint              y,
                    GtkSelectionData *selection_data,

{
  PrivateData *private_data = GET_PRIVATE_DATA (widget);

  if (private_data->suggested_action)
   {
     private_data->suggested_action = 0;

     // We are getting this data due to a request in drag_motion,
     // rather than due to a request in drag_drop, so we are just
     // supposed to call gdk_drag_status(), not actually paste in
     // the data.

     str = gtk_selection_data_get_text (selection_data);
     if (!data_is_acceptable (str))
       gdk_drag_status (context, 0, time);
     else
       gdk_drag_status (context,
                        private_data->suggested_action,
                        time);
   }
  else
   {
     // accept the drop
   }
}

`draw`

This signal is emitted when a widget is supposed to render itself. The widget’s top left corner must be painted at the origin of the passed in context and be sized to the values returned by [WidgetExtManual::allocated_width()][crate::gtk::prelude::WidgetExtManual::allocated_width()] and [WidgetExtManual::allocated_height()][crate::gtk::prelude::WidgetExtManual::allocated_height()].

Signal handlers connected to this signal can modify the cairo context passed as cr in any way they like and don’t need to restore it. The signal emission takes care of calling cairo_save() before and cairo_restore() after invoking the handler.

The signal handler will get a cr with a clip region already set to the widget’s dirty region, i.e. to the area that needs repainting. Complicated widgets that want to avoid redrawing themselves completely can get the full extents of the clip region with gdk_cairo_get_clip_rectangle(), or they can get a finer-grained representation of the dirty region with cairo_copy_clip_rectangle_list().

`enter-notify-event`

The ::enter-notify-event will be emitted when the pointer enters the widget’s window.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_ENTER_NOTIFY_MASK mask.

This signal will be sent to the grab widget if there is one.

`event`

The GTK+ main loop will emit three signals for each GDK event delivered to a widget: one generic ::event signal, another, more specific, signal that matches the type of event delivered (e.g. [key-press-event][struct@crate::gtk::Widget#key-press-event]) and finally a generic [event-after][struct@crate::gtk::Widget#event-after] signal.

`event-after`

After the emission of the [event][struct@crate::gtk::Widget#event] signal and (optionally) the second more specific signal, ::event-after will be emitted regardless of the previous two signals handlers return values.

`focus`

`focus-in-event`

The ::focus-in-event signal will be emitted when the keyboard focus enters the widget’s window.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_FOCUS_CHANGE_MASK mask.

`focus-out-event`

The ::focus-out-event signal will be emitted when the keyboard focus leaves the widget’s window.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_FOCUS_CHANGE_MASK mask.

`grab-broken-event`

Emitted when a pointer or keyboard grab on a window belonging to widget gets broken.

On X11, this happens when the grab window becomes unviewable (i.e. it or one of its ancestors is unmapped), or if the same application grabs the pointer or keyboard again.

`grab-focus`

Action

`grab-notify`

The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.

A widget is shadowed by a [WidgetExtManual::grab_add()][crate::gtk::prelude::WidgetExtManual::grab_add()] when the topmost grab widget in the grab stack of its window group is not its ancestor.

`hide`

The ::hide signal is emitted when widget is hidden, for example with [WidgetExtManual::hide()][crate::gtk::prelude::WidgetExtManual::hide()].

`hierarchy-changed`

The ::hierarchy-changed signal is emitted when the anchored state of a widget changes. A widget is “anchored” when its toplevel ancestor is a [gtk::Window][crate::gtk::Window]. This signal is emitted when a widget changes from un-anchored to anchored or vice-versa.

`key-press-event`

The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_KEY_PRESS_MASK mask.

This signal will be sent to the grab widget if there is one.

`key-release-event`

The ::key-release-event signal is emitted when a key is released.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_KEY_RELEASE_MASK mask.

This signal will be sent to the grab widget if there is one.

`keynav-failed`

Gets emitted if keyboard navigation fails. See [WidgetExtManual::keynav_failed()][crate::gtk::prelude::WidgetExtManual::keynav_failed()] for details.

`leave-notify-event`

The ::leave-notify-event will be emitted when the pointer leaves the widget’s window.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_LEAVE_NOTIFY_MASK mask.

This signal will be sent to the grab widget if there is one.

`map`

The ::map signal is emitted when widget is going to be mapped, that is when the widget is visible (which is controlled with [WidgetExtManual::set_visible()][crate::gtk::prelude::WidgetExtManual::set_visible()]) and all its parents up to the toplevel widget are also visible. Once the map has occurred, [map-event][struct@crate::gtk::Widget#map-event] will be emitted.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of [unmap][struct@crate::gtk::Widget#unmap].

`map-event`

The ::map-event signal will be emitted when the widget’s window is mapped. A window is mapped when it becomes visible on the screen.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_STRUCTURE_MASK mask. GDK will enable this mask automatically for all new windows.

`mnemonic-activate`

The default handler for this signal activates widget if group_cycling is false, or just makes widget grab focus if group_cycling is true.

`motion-notify-event`

The ::motion-notify-event signal is emitted when the pointer moves over the widget’s GdkWindow.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_POINTER_MOTION_MASK mask.

This signal will be sent to the grab widget if there is one.

`move-focus`

Action

`parent-set`

The ::parent-set signal is emitted when a new parent has been set on a widget.

This signal gets emitted whenever a widget should pop up a context menu. This usually happens through the standard key binding mechanism; by pressing a certain key while a widget is focused, the user can cause the widget to pop up a menu. For example, the [gtk::Entry][crate::gtk::Entry] widget creates a menu with clipboard commands. See the [Popup Menu Migration Checklist][checklist-popup-menu] for an example of how to use this signal.

Action

`property-notify-event`

The ::property-notify-event signal will be emitted when a property on the widget’s window has been changed or deleted.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_PROPERTY_CHANGE_MASK mask.

`proximity-in-event`

To receive this signal the GdkWindow associated to the widget needs to enable the GDK_PROXIMITY_IN_MASK mask.

This signal will be sent to the grab widget if there is one.

`proximity-out-event`

To receive this signal the GdkWindow associated to the widget needs to enable the GDK_PROXIMITY_OUT_MASK mask.

This signal will be sent to the grab widget if there is one.

Emitted when [has-tooltip][struct@crate::gtk::Widget#has-tooltip] is true and the hover timeout has expired with the cursor hovering “above” widget; or emitted when widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for widget. If this is the case true should be returned, false otherwise. Note that if keyboard_mode is true, the values of x and y are undefined and should not be used.

The signal handler is free to manipulate tooltip with the therefore destined function calls.

`realize`

The ::realize signal is emitted when widget is associated with a GdkWindow, which means that [WidgetExtManual::realize()][crate::gtk::prelude::WidgetExtManual::realize()] has been called or the widget has been mapped (that is, it is going to be drawn).

`screen-changed`

The ::screen-changed signal gets emitted when the screen of a widget has changed.

`scroll-event`

The ::scroll-event signal is emitted when a button in the 4 to 7 range is pressed. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_SCROLL_MASK mask.

This signal will be sent to the grab widget if there is one.

`selection-clear-event`

The ::selection-clear-event signal will be emitted when the the widget’s window has lost ownership of a selection.

`selection-get`

`selection-notify-event`

`selection-received`

`selection-request-event`

The ::selection-request-event signal will be emitted when another client requests ownership of the selection owned by the widget’s window.

`show`

The ::show signal is emitted when widget is shown, for example with [WidgetExtManual::show()][crate::gtk::prelude::WidgetExtManual::show()].

`show-help`

Action

`size-allocate`

`state-changed`

The ::state-changed signal is emitted when the widget state changes. See [WidgetExtManual::state()][crate::gtk::prelude::WidgetExtManual::state()].

`state-flags-changed`

The ::state-flags-changed signal is emitted when the widget state changes, see [WidgetExtManual::state_flags()][crate::gtk::prelude::WidgetExtManual::state_flags()].

`style-set`

The ::style-set signal is emitted when a new style has been set on a widget. Note that style-modifying functions like [WidgetExtManual::modify_base()][crate::gtk::prelude::WidgetExtManual::modify_base()] also cause this signal to be emitted.

Note that this signal is emitted for changes to the deprecated GtkStyle. To track changes to the GtkStyleContext associated with a widget, use the [style-updated][struct@crate::gtk::Widget#style-updated] signal.

`style-updated`

The ::style-updated signal is a convenience signal that is emitted when the GtkStyleContext::changed signal is emitted on the widget’s associated GtkStyleContext as returned by [WidgetExtManual::style_context()][crate::gtk::prelude::WidgetExtManual::style_context()].

Note that style-modifying functions like [WidgetExtManual::override_color()][crate::gtk::prelude::WidgetExtManual::override_color()] also cause this signal to be emitted.

`touch-event`

`unmap`

The ::unmap signal is emitted when widget is going to be unmapped, which means that either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

`unmap-event`

The ::unmap-event signal will be emitted when the widget’s window is unmapped. A window is unmapped when it becomes invisible on the screen.

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_STRUCTURE_MASK mask. GDK will enable this mask automatically for all new windows.

`unrealize`

The ::unrealize signal is emitted when the GdkWindow associated with widget is destroyed, which means that [WidgetExtManual::unrealize()][crate::gtk::prelude::WidgetExtManual::unrealize()] has been called or the widget has been unmapped (that is, it is going to be hidden).

`visibility-notify-event`

The ::visibility-notify-event will be emitted when the widget’s window is obscured or unobscured.

To receive this signal the GdkWindow associated to the widget needs to enable the GDK_VISIBILITY_NOTIFY_MASK mask.

`window-state-event`

The ::window-state-event will be emitted when the state of the toplevel window associated to the widget changes.

To receive this signal the GdkWindow associated to the widget needs to enable the GDK_STRUCTURE_MASK mask. GDK will enable this mask automatically for all new windows.

CellEditable

`editing-done`

This signal is a sign for the cell renderer to update its value from the cell_editable.

Implementations of GtkCellEditable are responsible for emitting this signal when they are done editing, e.g. [gtk::Entry][crate::gtk::Entry] emits this signal when the user presses Enter. Typical things to do in a handler for ::editing-done are to capture the edited value, disconnect the cell_editable from signals on the GtkCellRenderer, etc.

gtk_cell_editable_editing_done() is a convenience method for emitting GtkCellEditable::editing-done.

This signal is meant to indicate that the cell is finished editing, and the cell_editable widget is being removed and may subsequently be destroyed.

Implementations of GtkCellEditable are responsible for emitting this signal when they are done editing. It must be emitted after the GtkCellEditable::editing-done signal, to give the cell renderer a chance to update the cell’s value before the widget is removed.

gtk_cell_editable_remove_widget() is a convenience method for emitting GtkCellEditable::remove-widget.

Editable

`changed`

The ::changed signal is emitted at the end of a single user-visible operation on the contents of the GtkEditable.

E.g., a paste operation that replaces the contents of the selection will cause only one signal emission (even though it is implemented by first deleting the selection, then inserting the new content, and may cause multiple ::notify::text signals to be emitted).

`delete-text`

This signal is emitted when text is deleted from the widget by the user. The default handler for this signal will normally be responsible for deleting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the range of deleted text, or prevent it from being deleted entirely. The start_pos and end_pos parameters are interpreted as for gtk_editable_delete_text().

`insert-text`

This signal is emitted when text is inserted into the widget by the user. The default handler for this signal will normally be responsible for inserting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the inserted text, or prevent it from being inserted entirely.
