c++ - Windows 8 tablet does not display TabTip (on-screen keyboard) on top of Qt OpenGL application -
i have full screen qt opengl application needs display virtual keyboard (tabtip.exe) when input textboxes entered. problem i'm facing virtual keyboard appears behind application when keyboard invoked. have tried many different things , found way can make appear in front, if window not fullscreen (e.g. making 1 pixel less full screen in width and/or height). if have tablet in portrait mode still displays keyboard in full screen.
now i'm trying figure out if driver issue, qt issue, opengl issue or general windows issue.
any suggestions?
update:
i have investigated bit further , think see what's going on. windows 8, upon detecting monitor rotation set zero, , has opengl window matches desktop resolution , covers whole screen, kicks legacy mode blocks windows 8 themed animations running (including virtual keyboard). have suggestions on how can stop windows doing this? dwmenablecomposition has been removed in windows 8.
