You probably noticed that whenever a control gets focus there are changes
in its appearance i.e. a focus rectangle for command buttons, check boxes, radio buttons,
vertical scrollbar in Multiline edit etc.
The most commonly used control the Datawindow in its most commonly used form w/o title
bar does not have a clear automatic way to indicate that it has focus. If you have window
with two Datawindows it is very difficult to tell which one has focus if you lost count of
how many times you pressed tab. Well, this problem has a rather elegant solution. Place
the following code in Datawindow control:
Getfocus event: this.BorderStyle = StyleRaised!
Losefocus event: this.BorderStyle = StyleLowered!
Now this control will change to raised border whenever it would get focus and back to
lowered border when focus is lost. I recommend that you put this code in your framework to
get consistent behavior across your application.
