Lost Focus and GotFocus in c++

Question

How do you add code to these events for native c++?

I couldn't find a WM_LOSTFOCUS OR WM_GOTFOCUS; I only found WM_SETFOCUS. I need code to happen when my window loses focus, and regains it.

Thanks.

Answer 1

JUST BEFORE your window loses focus it will be sent: WM_KILLFOCUS
AFTER your window gains focus, it will be sent: WM_SETFOCUS

Sending a WM_SETFOCUS message does not set the focus. You need to call SetFocus for that.

Answer 2

For an edit control, WM_KILLFOCUS won't work.

Took me too long to figure out that I needed EN_KILLFOCUS. Hopefully saves the next guy some time.

Answer 3

The message you're looking for is WM_KILLFOCUS
