Hi,
I'm having a weird focus problem with an xterm embedded in a GtkDrawingArea.
When I put the main application on sleep, the xterm can get the focus.
Otherwise, it can't.
Could somebody suggest me a way to allow the embedded xterm to get the focus
when the GtkDrawingArea gets it?
A minimal example follows. Move the focus in and out of the window. The main
application will be put on sleep for 3 seconds when the GtkDrawingArea gets
the focus. During these 3 seconds, you can type in the embedded xterm. When
the main application wakes up, the embedded xterm loses the focus.
Thanks in advance for any help!
David
