Struct gtk4::AppChooserWidget

pub struct AppChooserWidget { /* private fields */ }

👎Deprecated: Since 4.10

Expand description

The application selection widgets should be implemented according to the design of each platform and/or application requiring them. AppChooserWidget is a widget for selecting applications.

It is the main building block for AppChooserDialog. Most applications only need to use the latter; but you can use this widget as part of a larger widget if you have special needs.

AppChooserWidget offers detailed control over what applications are shown, using the show-default, show-recommended, show-fallback, show-other and show-all properties. See the AppChooser documentation for more information about these groups of applications.

To keep track of the selected application, use the application-selected and application-activated signals.

§CSS nodes

AppChooserWidget has a single CSS node with name appchooser.

§Signals

§`application-activated`

Emitted when an application item is activated from the widget’s list.

This usually happens when the user double clicks an item, or an item is selected and the user presses one of the keys Space, Shift+Space, Return or Enter.

§`application-selected`

Emitted when an application item is selected from the widget’s list.

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 WidgetExt::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 gdk::Surface.

This means that WidgetExt::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 WidgetExt::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 gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).
