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. */ #include "config.h" #include "gtkappchooserbutton.h" #include "gtkappchooser.h" #include "gtkappchooserdialog.h" #include "gtkappchooserprivate.h" #include "gtkcelllayout.h" #include "gtkcellrendererpixbuf.h" #include "gtkcellrenderertext.h" #include "gtkcombobox.h" #include "gtkdialog.h" #include "gtkintl.h" #include "gtkmarshalers.h" enum { PROP_CONTENT_TYPE = 1, PROP_SHOW_DIALOG_ITEM, PROP_SHOW_DEFAULT_ITEM, PROP_HEADING };
