|
|
* #GtkApplication is a class that handles many important aspects
|
|
* of a GTK+ application in a convenient fashion, without enforcing
|
|
* a one-size-fits-all application model.
|
|
*
|
|
* Currently, GtkApplication handles GTK+ initialization, application
|
|
* uniqueness, provides some basic scriptability by exporting 'actions',
|
|
* and manages a list of toplevel windows whose life-cycle is automatically
|
|
* tied to the life-cycle of your application.
