Struct gtk::AppChooserButton [−][src]
pub struct AppChooserButton(_);
Expand description
The AppChooserButton
is a widget that lets the user select
an application. It implements the AppChooser
interface.
Initially, a AppChooserButton
selects the first application
in its list, which will either be the most-recently used application
or, if property::AppChooserButton::show-default-item
is true
, the
default application.
The list of applications shown in a AppChooserButton
includes
the recommended applications for the given content type. When
property::AppChooserButton::show-default-item
is set, the default application
is also included. To let the user chooser other applications,
you can set the property::AppChooserButton::show-dialog-item
property,
which allows to open a full AppChooserDialog
.
It is possible to add custom items to the list, using
AppChooserButtonExt::append_custom_item()
. These items cause
the signal::AppChooserButton::custom-item-activated
signal to be
emitted when they are selected.
To track changes in the selected application, use the
signal::ComboBox::changed
signal.
