Struct libhandy::TabBar

source ·

pub struct TabBar { /* private fields */ }

Available on crate feature v1_2 only.

Expand description

A tab bar for TabView.

The TabBar widget is a tab bar that can be used with conjunction with TabView.

TabBar can autohide and can optionally contain action widgets on both sides of the tabs.

When there’s not enough space to show all the tabs, TabBar will scroll them. Pinned tabs always stay visible and aren’t a part of the scrollable area.

CSS nodes

TabBar has a single CSS node with name tabbar.

Properties

`autohide`

Whether tabs automatically hide.

If set to TRUE, the tab bar disappears when the associated TabView has 0 or 1 tab, no pinned tabs, and no tab is being transferred.

See tabs-revealed.

Readable | Writeable

The widget shown after the tabs.

Readable | Writeable

`expand-tabs`

Whether tabs should expand.

If set to TRUE, the tabs will always vary width filling the whole width when possible, otherwise tabs will always have the minimum possible size.

Readable | Writeable

`extra-drag-dest-targets`

Extra drag destination targets.

Allows to drag arbitrary content onto tabs, for example URLs in a web browser.

If a tab is hovered for a certain period of time while dragging the content, it will be automatically selected.

After content is dropped, the extra-drag-data-received signal can be used to retrieve and process the drag data.

Readable | Writeable

`inverted`

Whether tabs use inverted layout.

If set to TRUE, non-pinned tabs will have the close button at the beginning and the indicator at the end rather than the opposite.

Readable | Writeable

`is-overflowing`

Whether the tab bar is overflowing.

If set to TRUE, all tabs cannot be displayed at once and require scrolling.

Readable

The widget shown before the tabs.

Readable | Writeable

`tabs-revealed`

Whether tabs are currently revealed.

See autohide.

Readable

`view`

The TabView the tab bar controls.

Container

Widget

`double-buffered`

Whether the widget is double buffered.

Readable | Writeable

`expand`

Whether to expand in both directions. Setting this sets both #GtkWidget:hexpand and #GtkWidget:vexpand

Readable | Writeable

`focus-on-click`

Whether the widget should grab focus when it is clicked with the mouse.

This property is only relevant for widgets that can take focus.

Before 3.20, several widgets (GtkButton, GtkFileChooserButton, GtkComboBox) implemented this property individually.

Readable | Writeable

`halign`

How to distribute horizontal space if widget gets extra space, see #GtkAlign

Readable | Writeable

Enables or disables the emission of #GtkWidget::query-tooltip on @widget. A value of true indicates that @widget can have a tooltip, in this case the widget will be queried using #GtkWidget::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.

Readable | Writeable

`height-request`

Readable | Writeable

`hexpand`

Readable | Writeable

`margin`

Sets all four sides’ margin at once. If read, returns max margin on any side.

Readable | Writeable

`margin-bottom`

Margin on bottom side of widget.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from gtk_widget_set_size_request() for example.

Readable | Writeable

`margin-end`

Margin on end of widget, horizontally. This property supports left-to-right and right-to-left text directions.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from gtk_widget_set_size_request() for example.

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: #GtkWidget:has-tooltip will automatically be set to true and there will be taken care of #GtkWidget::query-tooltip in the default signal handler.

Note that if both #GtkWidget:tooltip-text and #GtkWidget:tooltip-markup are set, the last one wins.

Readable | Writeable

See drag-data-received.

Container

`add`

`check-resize`

`remove`

`set-focus-child`

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 #GtkWidget 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 gtk_widget_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. gtk_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 #GtkWidget::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 #GtkWidget::drag-data-received handler which gets triggered by calling gtk_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 #GtkWidget::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 #GtkWidget::drag-motion, e.g. undo highlighting with gtk_drag_unhighlight().

Likewise, the #GtkWidget::drag-leave signal is also emitted before the ::drag-drop signal, for instance to allow cleaning up of a preview item created in the #GtkWidget::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 gtk_drag_get_data() and defer the gdk_drag_status() call to the #GtkWidget::drag-data-received handler. Note that you must pass #GTK_DEST_DEFAULT_DROP, #GTK_DEST_DEFAULT_MOTION or #GTK_DEST_DEFAULT_ALL to gtk_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 #GtkWidget::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 gtk_drag_highlight().

⚠️ The following code is in C ⚠️

static void
drag_motion (GtkWidget      *widget,
             GdkDragContext *context,
             gint            x,
             gint            y,
             guint           time)
{
  GdkAtom target;

  PrivateData *private_data = GET_PRIVATE_DATA (widget);

  if (!private_data->drag_highlight)
   {
     private_data->drag_highlight = 1;
     gtk_drag_highlight (widget);
   }

  target = gtk_drag_dest_find_target (widget, context, NULL);
  if (target == GDK_NONE)
    gdk_drag_status (context, 0, time);
  else
   {
     private_data->pending_status
        = gdk_drag_context_get_suggested_action (context);
     gtk_drag_get_data (widget, context, target, time);
   }

  return TRUE;
}

static void
drag_data_received (GtkWidget        *widget,
                    GdkDragContext   *context,
                    gint              x,
                    gint              y,
                    GtkSelectionData *selection_data,
                    guint             info,
                    guint             time)
{
  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 gtk_widget_get_allocated_width() and gtk_widget_get_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. #GtkWidget::key-press-event) and finally a generic #GtkWidget::event-after signal.

`event-after`

After the emission of the #GtkWidget::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 gtk_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 gtk_widget_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 #GtkWindow. 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 gtk_widget_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 gtk_widget_set_visible()) and all its parents up to the toplevel widget are also visible. Once the map has occurred, #GtkWidget::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 #GtkWidget::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 #GtkEntry 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 #GtkWidget: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 gtk_widget_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 gtk_widget_show().

`show-help`

Action

`size-allocate`

`state-changed`

The ::state-changed signal is emitted when the widget state changes. See gtk_widget_get_state().

`state-flags-changed`

The ::state-flags-changed signal is emitted when the widget state changes, see gtk_widget_get_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 gtk_widget_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 #GtkWidget::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 gtk_widget_get_style_context().

Note that style-modifying functions like gtk_widget_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 gtk_widget_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.
