Is there a way I can check whether a window is in focus?

I have a window that is sometimes in the background and has a timer
running every second. Sometimes when a certain condition exists it gives
focus to a single line edit. This is perfect when the window is in
focus, but annoying when you are in another window, since it robs the
cursor from the window you are working in.

Can I check whether the window has focus before I set the focus to the SLE?

Thanks for all the help I get here. VO still works very well!

James

You can use the FocusChange() and Activate() callback events of the
Window class.

The docs has an explanation and sample code for those events.

Thanks. I saw them this morning but wasn't sure what they were for. Do
you know whether switching between tabs also works the same way? When
you switch between tabs you change window focus on one hand, however in
another sense you are still in the same master window.

For the tab selection changing, in the parent window (the one has the
tabcontrol), look at the Properties, CommonControl Events, then select
TabSelChanging.
