XtSetKeyboardFocus(3) XT FUNCTIONS XtSetKeyboardFocus(3) NAME XtSetKeyboardFocus - focus events on a child widget SYNTAX #include <X11/Intrinsic.h> void XtSetKeyboardFocus(Widget subtree, Widget descendant); ARGUMENTS subtree Specifies either the widget in the subtree structure which is to receive the keyboard event, or None. Note that it is not an er- ror to specify None when no input focus was previously set. descendantSpecifies the widget for which the keyboard focus is to be set. DESCRIPTION If a future KeyPress or KeyRelease event occurs within the specified sub- tree, XtSetKeyboardFocus causes XtDispatchEvent to remap and send the event to the specified descendant widget. When there is no modal cascade, keyboard events can occur within a widget W in one of three ways: * W has the X input focus. * W has the keyboard focus of one of its ancestors, and the event occurs within the ancestor or one of the ancestor's descendants. * No ancestor of W has a descendant within the keyboard focus, and the pointer is within W. When there is a modal cascade, a widget W receives keyboard events if an ancestor of W is in the active subset of the modal cascade and one or more of the previous conditions is True. When subtree or one of its descendants acquires the X input focus or the pointer moves into the subtree such that keyboard events would now be de- livered to subtree, a FocusIn event is generated for the descendant if Fo- cusNotify events have been selected by the descendant. Similarly, when W loses the X input focus or the keyboard focus for one of its ancestors, a FocusOut event is generated for descendant if FocusNotify events have been selected by the descendant.
