My application has got an integrated form designer with its own code. All works fine, but in tEdit and other controls which can get the focus, the control catches the focus and proceeds all user input like mouse clicks and cursors. In the form designer, this functionality should "sleep" and gets substituted by the form designer events, e.g. "Ctrl-cursor right" on a selected tEdit control moves the component by one pixel in design mode instead of moving the tEdit text cursor in non-design mode. I tried to turn on/off the csDesigning ComponentState property (this property is protected, I used the code in designer\jitforms.pp) and a lot of other stuff, with no effect. What is the correct property I need to change?
