I manually commented out the code... if WidgetSet.GetDpiForMonitor(FHandle, MDT_EFFECTIVE_DPI, X, Y)=S_OK then ... else and only left the "Result = Screen.PixelsPerInch;" call in place. If you didn't guess, it is a temporary fix. ;-) Regards, Graeme -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://fpgui.sourceforge.net/ My public PGP key: http://tinyurl.com/graeme-pgp -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
[Lazarus] FHandle causes AV in TMonitor.GetPixelsPerInch()
I'm debugging the issue reported about LCL-CustomDraw and lcl-fpgui causing an AV at application start up. I traced the issue back to TMonitor.GetPixelsPerInch() which is called in TCustomForm.AfterConstruction(). As soon as GetPixelsPerInch() tries to reference FHandle in any way, it throws an AV. Anybody got some hints as to why both custom drawn widgetsets have this issue? Would it be some window handle allocation timing issue for custom drawn widgetest? ie: The handles are allocated later that other non Object Pascal based widgetsets?

Should I report a bug? fpGUI already has that information. I'll take a look at LCL-fpGUI and supply a patch if needed for that. I'll also take a look at the other LCL-fpGUI issues you said appears. The LCL-fpGUI really needs a dedicated developer to get it out of alpha/beta stage.
