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

Initially, a gtk:app-chooser-button widget 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 widget 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 widget.

It is possible to add custom items to the list, using the gtk:app-chooser-button-append-custom-item function. 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.
