Hi,
I wanted to catch the F1 key to show a quick version message. I expected to do this by trapping VK_F1 in a KeyDown event.
Firstly any key constants like VK_SPACE and VK_F1 seem undefined. Aren't these defined in LCL somewhere?
Secondly, the keydown event is not happening. My recollection was that any key not serviced by a window will get passed back to its parent until it gets to the top level ( the "form" ) window.
I have a bunch of TEdits in a Tgroupbox in Tpanel on a form. Am I correct in thinking F1 will bubble up to the form?
TIA.

Add LCLType unit in to your uses clause.

Do you mean that your Edit1 has focus, and an Edit1KeyDown event is not called when you press F1?
Edit keydown events work as expected here.
Perhaps you need to share compilable code that illustrates the problem you have.

Many thanks, that is what was looking for.
