Struct SplitButton 

pub struct SplitButton { /* private fields */ }

A combined button and dropdown widget.

SplitButton is typically used to present a set of actions in a menu, but allow access to one of them with a single click.

The API is very similar to Gtk::Button and Gtk::MenuButton, see their documentation for details.

CSS nodes

splitbutton[.image-button][.text-button]
├── button
│   ╰── <content>
├── separator
╰── menubutton
    ╰── button.toggle
        ╰── arrow

SplitButton’s CSS node is called splitbutton. It contains the css nodes: button, separator, menubutton. See Gtk::MenuButton documentation for the menubutton contents.

The main CSS node will contain the .image-button or .text-button style classes matching the button contents. The nested button nodes will never contain them.

Style classes

SplitButton can use some of the same style classes as Gtk::Button:

• .suggested-action
• .destructive-action
• .flat
• .raised

Other style classes, like .pill, cannot be used.

Accessibility

SplitButton uses the GTK_ACCESSIBLE_ROLE_GROUP role.

Properties

can-shrink

Whether the button can be smaller than the natural size of its contents.

If set to TRUE, the label will ellipsize.

See [can-shrink][struct@crate::Gtk::Button#can-shrink] and [can-shrink][struct@crate::Gtk::MenuButton#can-shrink].

Readable | Writeable

child

The child widget.

Setting the child widget will set label and icon-name to NULL.

Readable | Writeable

direction

The direction in which the popup will be popped up.

The dropdown arrow icon will point at the same direction.

If the does not fit in the available space in the given direction, GTK will try its best to keep it inside the screen and fully visible.

If you pass GTK_ARROW_NONE, it’s equivalent to GTK_ARROW_DOWN.

Readable | Writeable

dropdown-tooltip

The tooltip of the dropdown button.

The tooltip can be marked up with the Pango text markup language.

Readable | Writeable

icon-name

The name of the icon used to automatically populate the button.

Setting the icon name will set label and child to NULL.

Readable | Writeable

label

The label for the button.

Setting the label will set icon-name and child to NULL.

Readable | Writeable

menu-model

The GMenuModel from which the popup will be created.

If the menu model is NULL, the dropdown is disabled.

A gtk::Popover will be created from the menu model with Gtk::PopoverMenu::new_from_model(). Actions will be connected as documented for this function.

If popover is already set, it will be dissociated from the button, and the property is set to NULL.

Readable | Writeable

popover

The gtk::Popover that will be popped up when the dropdown is clicked.

If the popover is NULL, the dropdown is disabled.

If menu-model is set, the menu model is dissociated from the button, and the property is set to NULL.

Signals

activate

Emitted to animate press then release.

This is an action signal. Applications should never connect to this signal, but use the clicked signal.

Action

clicked

Emitted when the button has been activated (pressed and released).

Action

Widget

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.

direction-changed

Emitted when the text direction of a widget changes.

hide

Emitted when @widget is hidden.

keynav-failed

Emitted if keyboard navigation fails.

See [WidgetExtManual::keynav_failed()][crate::gtk::prelude::WidgetExtManual::keynav_failed()] for details.

map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

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.

mnemonic-activate

Emitted when a widget is activated via a mnemonic.

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

move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property 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

Emitted when @widget is associated with a GdkSurface.

This 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).

show

Emitted when @widget is shown.

state-flags-changed

Emitted when the widget state changes.

See [WidgetExtManual::state_flags()][crate::gtk::prelude::WidgetExtManual::state_flags()].

unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when 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.

unrealize

Emitted when the GdkSurface associated with @widget is destroyed.

This 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).
