Subject: [PATCH 01/68] Add invariant that a child is unmapped if parent is
|
|
unmapped
|
|
|
|
Requires fixes to GtkContainer and GtkWindow to unmap their
|
|
children, rather than just withdrawing or hiding the container
|
|
window.
|
|
|
|
Requires fix to GtkHandleBox to chain up to GtkContainer unmap.
|
|
|
|
Historically we avoided these unmaps for efficiency reasons,
|
|
but these days it's a bigger problem that there's no way
|
|
for child widgets to know that one of their ancestors has
|
|
become unmapped.
|
|
(cherry picked from commit b67c5af55bf611c013b2c43e6878281abd773530)
