[Lazarus] Forms.pp function error?
As pointed by Dmitry B, and checked by myself in LCL, MK_ALT must be defined in LCLType.pp as $2000. For ex, this is sample from qtwidgets.pas: if (ModifierState and MK_SHIFT) <> 0 then Msg.State := [ssShift]; if (ModifierState and MK_CONTROL) <> 0 then Msg.State := [ssCtrl] + Msg.State; if (ModifierState and $2000) <> 0 then Msg.State := [ssAlt] + Msg.State; patch added. -- Regards, Alexey Index: lcl/lcltype.pp === --- lcl/lcltype.pp (revision 59355) +++ lcl/lcltype.pp (working copy) @@ -2836,6 +2836,7 @@ MK_DOUBLECLICK = $80; MK_TRIPLECLICK = $100; MK_QUADCLICK = $200; + MK_ALT = $2000; // used (as number) by several widgetsets //== // Constants from commctrl -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

Value $400 makes sense. And also this must be changed then: function KeysToShiftState(Keys: PtrUInt): TShiftState; it uses same constants. Alex -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
