Includes

#include <gtk/gtk.h>

Description

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 “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 “show-default-item” is set, the default application is also included. To let the user chooser other applications, you can set the “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 “custom-item-activated” signal to be emitted when they are selected.

To track changes in the selected application, use the “changed” signal.

Functions

GtkWidget *
gtk_app_chooser_button_new (const gchar *content_type);

Creates a new GtkAppChooserButton for applications that can handle content of the given type.
