Possible Tab3 bug

19 Apr 2020, 20:23

I encounter a very strange problem with Tab3: A white box appears when I paste text to an Edit control. The position of the box is not always the same. It looks like a redraw problem. It disappears after changing Tab3 to Tab2 .

It happens randomly. It seems also related with the text to paste.

My System: Windows 7 Pro, AHK 1.1.32 64Bit

Test code:

Code: Select all


#NoTrayIcon
#SingleInstance force
Gui,1: Add, Tab3, x10 y320 w820 h390 vSettingTab10, Code Preview
Gui, Font, S11,
Gui,1: Add, Edit,x20 y350 w450 h350 
Gui,1: Add, Edit, x480 y350 w340 h350 
Gui, Font, S8,
Gui,1: Tab,
Gui,1: Show, w1000 h720, TEST

return

GuiClose:
GuiEscape:
ExitApp
Return

Code: Select all

The redrawing is completely handled by your local system.
So while this may indeed be a bug there is a high chance its not one in autohotkey.

The white box never moves when the text is scrolled? Does Redraw have any effect before or after the Show?
Same white box for different fonts? e.g.

Code: Select all

Gui, Font, s11, Verdana

To nnnik: Tab2 doesn't have the problem. That's why I think It's a bug of Tab3. But you are also right. I tested the code on a Windows 10 machine, everything was fine.


To Imstearn: As soon as I touch anything, the white box will disappear. For example scroll the text, or paste text to another Edit. Changing font doesn't work.

Thank you all!
