XtSetKeyboardFocus(3Xt) X11R5 XtSetKeyboardFocus(3Xt)NAMEXtSetKeyboardFocus - focus events on a child widget
SYNTAX
XtSetKeyboardFocus(subtree descendant)
Widget subtree, descendant;
ARGUMENTS
descendant
Specifies either the widget in the subtree structure which is
to receive the keyboard event, or Note that it is not an
error to specify when no input focus was previously set.
w Specifies the widget for which the keyboard focus is to be
set.
DESCRIPTION
If a future or event occurs within the specified subtree, causes to
remap and send the event to the specified descendant widget.
When there is no modal cascade, keyboard events can occur within a wid‐
get 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
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 delivered to subtree, a event is generated for the descendant if
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
event is generated for descendant if events have been selected by the
descendant.
