GtkWidget had a hack where if opacity is 0.999 we set up an opacity
|
|
group when rendering the widget. This is no longer needed in 3.10,
|
|
and GtkStack doesn't use it anymore. It has been removed in 3.12.
|
|
GdStack is using it, so applications should be ported from GdStack
|
|
to GtkStack in 3.12.
|
|
</p>
|
|
<p>
|
|
GtkHeaderBar in 3.10 was not ordering its pack-end children in
|
|
the right way. This has been fixed in 3.12. Applications which
|
|
pack multiple widgets at the end of a headerbar will have to
|
|
be updated.
|
|
</p>
|
|
<p>
|
|
gtk_text_view_add_child_in_window has changed behaviour a bit.
|
|
It now always positions the child in buffer coordinates, where
|
|
it used to inconsistently scroll with the buffer but then go
|
|
reposition to a window-relative position on redraw.
|
|
</p>
|
|
<p>
|
|
A number of container widgets have been made more compliant with
|
|
the uniform CSS rendering model by making them render backgrounds
|
|
and borders. This may require some adjustments in applications that
|
|
were making assumptions about containers never rendering backgrounds.
