wxAuiNotebook - tabartgtk - gapbox not drawn, if active tab invisible
|Reported by:||jens||Owned by:|
If the active tab is not visible tabartgtk does not draw the gapbox.
The attached patch fixes this by drawing an gtk-box for inactive tabs.
For active tabs we draw a box without border, because some themes have transparent gaps and a line would be visible at the bottom of the tab (in the gap).
I also increased the height of the gapbox, because on some themes the bottom (or top, depending on alignment) part of the box is visible otherwise (should be hidden by the tab-content).
