Steve,
But you see, that's the problem. I can't tell when it's activated.
I'm talking about the case when a user either clicks on the control
or tabs to it from another control. I can't tell when scintilla gets
the focus.
Anyway, I've put a hack into place that seems to work for now. I
won't post the code (unless someone wants me to) since it's truly
evil, but here's what I did. In the WndProc method in the
ScintillControl class I examined the messages comming from Windows
and noticed 2 particular messages that always got sent when the
control was getting and loosing focus (they're both WM_COMMAND
messages). The notification part of WParam is 0x02000000 during a
'got focus' and 0x01000000 during a 'lost focus'. I detect these
messages and call my own 'OnMyGotFocus' and 'OnMyLostFocus' methods.
It seems to work ok and seems to be reliable. I'm sure it's not the
right way to do this, but it seems to take care of the problem.
One thing I didn't do, but I should have (although it doesn't effect
me right now) is set the IsFocus property when I detect those
messages, just to make things more consistent.
