With MSWSetTransparentBackground() hack only the panel which was the immediate child of wxNotebook (i.e. its page) inherited the notebook background but not its children. This resulted in jarring background discontinuities when nested panels were used. Fix this by inheriting notebook background in all child panels by testing for the return value of the parents MSWHasInheritableBackground() method in wxPanel::HasTransparentBackground() recursively. Closes #12317. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65238 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 |
