not the one stripped from mnemonics (this was inconsistent with the other ports and resulted in problems when using wxUpdateUIEvent::SetText()) 2. added wxControl::GTKConvertMnemonics(), GTKRemoveMnemonics() and also helper GTKSetLabelForLabel() and GTKSetLabelForFrame() wrappers 3. use them instead of duplicating their code in different derived controls git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@36435 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
