Re: Focus Help!

Andy Piper <andy(a)xemacs.org&gt; writes: Clicking on (or just entering) a push button shouldn't even grab the keyboard focus. On the other hand, for textual subwidgets, the two policies are acceptable: either you get keyboard focus when entering the widget's window, in which case leaving the window should give you back the old keyboard focus, or you have to click in the widget to get keyboard events. But then, you'll have to click back outside. Yes. Under X, the keyboard is always attached to a window (possibly the root window). This window is said to be the focus window. However, this does not mean that this window will receive keyboard events. If for example XtSetKeyboardFocus has been called, the keyboard events could be remaped to go to a child of the focus window. I don't know, and I don't have time to investigate, sorry. Try to figure out if/how XSetInputFocus is used. It's possible that somewhere in the code, a click on a widget leads to calling XtSetKeyboardFocus, but never release it. Also, if you have to track when the pointer leaves a subwidget in order to restore the focus, you'll have to select the LeaveNotify events. -- / / _ _ Didier Verna http://www.inf.enst.fr/~verna/ - / / - / / /_/ / ENST, INFRES C201.1 mailto:verna＠inf.enst.fr /_/ / /_/ / /__ / 46 rue Barrault Tel. +33 (1) 45 81 73 46 75013 Paris, France Fax. +33 (1) 45 81 31 19
