The gtk-app-chooser-button is a widget that lets the user select an application. It implements the gtk-app-chooser interface.

Initially, a gtk-app-chooser-button selects the first application in its list, which will either be the most-recently used application or, if the show-default-item property is true, the default application.

The list of applications shown in a gtk-app-chooser-button includes the recommended applications for the given content type. When the show-default-item property 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 gtk-app-chooser-dialog.

It is possible to add custom items to the list, using the function 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.

The "custom-item-activated" signal

 lambda (widget item-name)    : Has Details      

Emitted when a custom item, previously added with the function gtk-app-chooser-button-append-custom-item, is activated from the dropdown menu.

widget
