Hello, I'm trying port components from delphi to lazarus, cross platform and QT widgetset CreateWindowEx On this winAPI I stoped and no info much for convert to widgetset. Can anyone has anyidea? What is aqual CreateWindowEx, DestroyWindow in linux QT widgetset? My system is Kubuntu x64 and last svn fpc lazarus Thank you procedure CreateToolTip; begin fhToolTip := CreateWindowEx(0, 'Tooltips_Class32', nil, TTS_ALWAYSTIP or TTS_BALLOON or TTS_NOPREFIX, Integer(CW_USEDEFAULT), Integer(CW_USEDEFAULT),Integer(CW_USEDEFAULT), Integer(CW_USEDEFAULT), Handle, 0, hInstance, nil); if fhToolTip 0 then SetWindowPos(fhToolTip, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE or SWP_NOACTIVATE); end; procedure DestroyToolTip; begin DestroyWindow(FHToolTip); end; -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Need help about CreateWindowEx
It looks like the code tries to create a tooltip window. I think Lazarus provides this functionality by itself in a cross-platform way, so you may want to look up that and replace the functionality there. An alternative would be to create the tooltip window yourself. The code you show isn't just creating any window, but it creates a window of the class Tooltips_Class32 specifically which AFAIK provides the tooltip functionality. So what you need to replace isn't the CreateWindow part (that would be easy), but the tooltip functionality part.
