/* Model Button
|
||
|
|
*
|
||
|
|
* GtkModelButton is a button widget that is designed to be used with
|
||
|
|
* a GAction as model. The button will adjust its appearance according
|
||
|
|
* to the kind of action it is connected to.
|
||
|
|
*
|
||
|
|
* It is also possible to use GtkModelButton without a GAction. In this
|
||
|
|
* case, you should set the "role" attribute yourself, and connect to the
|
||
|
|
* "clicked" signal as you would for any other button.
|
||
|
|
*
|
||
|
|
* A common use of GtkModelButton is to implement menu-like content
|
||
|
|
* in popovers.
