Subject: Bug 479580 - Widgets with V_SCROLL not scrollable
|
|
|
|
Hiding scrollbar for widget created with style V_SCROLL shouldn't stop
|
|
other means of scrolling e.g. mouse wheel.
|
|
The fix is to use new GTK_POLICY_EXTERNAL (added in GTK 3.16) which
|
|
allows scrolling when scrollbars invisible which was not the possible
|
|
before that.
|
|
