* ShellGtkEmbed; the resizing logic is bound to the clutter logic.

*
|
|

|
* The typical usage we might expect is
|
|
|
|
*
|
|
|
|
* - ShellEmbeddedWindow is created and filled with content
|
|
|
|
* - ShellEmbeddedWindow is shown with gtk_widget_show_all()
|
|
|
|
* - ShellGtkEmbed is created for the ShellEmbeddedWindow
|
|
|
|
* - actor is added to a stage
|
|
|
|
*
|
2012-03-25 10:02:17 +00:00
|
|
|
* The way it works is that the GtkWindow is mapped if and only if both:
|
2009-05-03 17:05:15 +00:00
|
|
|
*
|
2012-03-25 10:02:17 +00:00
|
|
|
* - gtk_widget_visible (window) [widget has been shown]
|
2009-05-03 17:05:15 +00:00
|
|
|
* - Actor is mapped [actor and all parents visible, actor in stage]
