How can I direct the keyboard input to a particular widget?
In Motif 1.1 call XmProcessTraversal(target, XmTRAVERSE_CURRENT). The widget (and all of its ancestors) does need to be realized BEFORE you call this. Otherwise it has no effect. XmProcessTraversal is reported to have many bugs, so it may not work right. A common occurrence is that it doesn’t move to the widget, but if you call XmProcessTraversal *twice* in a row, it will. If you can’t get it to work, try this from Kee Hinckley: // This insane sequence is as follows: // On manage set up a focus callback // On focus callback set up a timer (and get rid of focus callback!) // On timer set the focus (which only works if the parent // has the focus, // which is why we went through all of this garbage) // There may be a better way, but I haven’t time to try it now. // static void focusTO(void *data, XtIntervalId *) { XmProcessTraversal((Widget) data, XmTRAVERSE_CURRENT); } static void focusCB(Widget w, XtPointer data, XtPointer) { XtRemoveCallback(w, XmNfocusCallback, focusCB, data); XtAppA
