AppChooserButton

open class AppChooserButton : ComboBox, AppChooserButtonProtocol

The GtkAppChooserButton is a widget that lets the user select an application. It implements the GtkAppChooser interface.

Initially, a GtkAppChooserButton selects the first application in its list, which will either be the most-recently used application or, if GtkAppChooserButton:show-default-item is true, the default application.

The list of applications shown in a GtkAppChooserButton includes the recommended applications for the given content type. When GtkAppChooserButton:show-default-item is set, the default application is also included. To let the user chooser other applications, you can set the GtkAppChooserButton:show-dialog-item property, which allows to open a full GtkAppChooserDialog.

It is possible to add custom items to the list, using gtk_app_chooser_button_append_custom_item(). These items cause the GtkAppChooserButton::custom-item-activated signal to be emitted when they are selected.

To track changes in the selected application, use the GtkComboBox::changed signal.

The AppChooserButton type acts as a reference-counted owner of an underlying GtkAppChooserButton instance. It provides the methods that can operate on this data type through AppChooserButtonProtocol conformance. Use AppChooserButton as a strong reference or owner of a GtkAppChooserButton instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the AppChooserButton instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkAppChooserButton>)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the AppChooserButton instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkAppChooserButton>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the AppChooserButton instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

override public init!(gconstpointer op: gconstpointer?)

    Parameters
