AppChooserWidget
is a widget for selecting applications.
It is the main building block for AppChooserDialog
. Most
applications only need to use the latter; but you can use
this widget as part of a larger widget if you have special needs.
AppChooserWidget
offers detailed control over what applications
are shown, using the
AppChooserWidget
:show-default
,
AppChooserWidget
:show-recommended
,
AppChooserWidget
:show-fallback
,
AppChooserWidget
:show-other
and
AppChooserWidget
:show-all
properties. See the AppChooser
documentation for more information
about these groups of applications.
To keep track of the selected application, use the
AppChooserWidget
::application-selected
and AppChooserWidget
::application-activated
signals.
CSS nodes
GtkAppChooserWidget has a single CSS node with name appchooser.
