|Summary||0032199: Sparta form designer component event and delete problems on gtk2|
|Description||As of right now the sparta docked form designer is preventing the creation of default events and your cannot deleted controls with keyboard when using the gtk2 widgetset.|
I highly suspect these two issues are related to the same bug, so I am filing them together.
|Steps To Reproduce||On lazarus with the gtk2 widgetset and sparta form designer installed.|
Drop a TButton on the a new form.
Double click the button.
Press the delete key.
Lazarus creates a Button1Click method handled associated with Button1.
The button is removed from the form.

||Yes I can reproduce. I wonder why there are so many widgetset dependent bugs. The code should not depend on widgetsets.|
It's not a problem of package but GTK2 mouse events.
In TDesigner.MouseDownOnControl the return of GetMouseMsgShift(TheMessage,Shift,Button) in GTK2 there never is ssDouble if Shift (like in Win32).
Wired, if I test a normal program, there in MouseUp ssDouble is in Shift. Maybe Ondrej know, what the problem is (the last big changes were done in revisions 51571, 51723, 51725, 51726). If not, I'll try to find a solution.
||Delete key is not working either. The double-click issue does not explain that.|
I was just wondering why a double click isn't working to create the default event handler. And don't checked the complete issue.
[Edit] Revision 56048 (issue 0032515) fixes the deleting part for me.
I fixed this issue with a workaround. The mouse messages are called for a control (e.g. TButton) and a directed control (TCustomPanel). The LCL accepts just one control for LastMouse. So I don't allow it for the second one.
As far as I could test, it will not break any code (the messages before were also wrong, as for the first control, never a MouseUp is called after MouseDown). But maybe I miss a special case, so I'll not apply it to 1.8 branch.
||Tested in trunk revision and is fixed. The fix did not make it into lazarus 1.8 :(|
