Subject: [PATCH] checkbutton: Fix redraw issues
|
|
|
|
This is a hack to get around the optimizations done by the CSS engine.
|
|
|
|
The CSS engine will notice that no CSS properties changed on the
|
|
widget itself when going from one state to another and not queue
|
|
a redraw.
|
|
And the reason for no properties changing will be that only the
|
|
checkmark itself changes, but that is hidden behind a
|
|
gtk_style_context_save()/_restore() pair, so it won't be caught.
