/**
* GtkAppChooserDialog :
*
* ` GtkAppChooserDialog ` shows a ` GtkAppChooserWidget ` inside a ` GtkDialog ` .
*
* < picture >
* < source srcset = " appchooserdialog - dark . png " media = " ( prefers - color - scheme : dark ) " >
* < img alt = " An example GtkAppChooserDialog " src = " appchooserdialog . png " >
* < / picture >
*
* Note that ` GtkAppChooserDialog ` does not have any interesting methods
* of its own . Instead , you should get the embedded ` GtkAppChooserWidget `
* using [ method @ Gtk . AppChooserDialog . get_widget ] and call its methods if
* the generic [ iface @ Gtk . AppChooser ] interface is not sufficient for
* your needs .
*
* To set the heading that is shown above the ` GtkAppChooserWidget ` ,
* use [ method @ Gtk . AppChooserDialog . set_heading ] .
*
* # # CSS nodes
*
* ` GtkAppChooserDialog ` has a single CSS node with the name ` window ` and style
* class ` . appchooser ` .
*
* Deprecated : 4 . 10 : The application selection widgets should be
* implemented according to the design of each platform and / or
* application requiring them .
