gtk.app_chooser_button
Module for [AppChooserButton] class
Types 3
The gtk.app_chooser_button.AppChooserButton lets the user select an application.
!An example GtkAppChooserButton
Initially, a gtk.app_chooser_button.AppChooserButton selects the first application in its list, which will either be the most-recently used application or, if gtk.app_chooser_button.AppChooserButton.showDefaultItem is true, the default application.
The list of applications shown in a gtk.app_chooser_button.AppChooserButton includes the recommended applications for the given content type. When gtk.app_chooser_button.AppChooserButton.showDefaultItem is set, the default application is also included. To let the user chooser other applications, you can set the gtk.app_chooser_button.AppChooserButton.showDialogItem property, which allows to open a full gtk.app_chooser_dialog.AppChooserDialog.
It is possible to add custom items to the list, using gtk.app_chooser_button.AppChooserButton.appendCustomItem. These items cause the gtk.app_chooser_button.AppChooserButton.customItemActivated signal to be emitted when they are selected.
To track changes in the selected application, use the gtk.app_chooser_button.AppChooserButton.changed signal.
CSS nodes
