XtSetSensitive(3Xt) X11R5 XtSetSensitive(3Xt)NAME
XtSetSensitive, XtIsSensitive - set and check a widget's sensitivity
state
SYNTAX
void XtSetSensitive(w, sensitive)
Widget w;
Boolean sensitive;
Boolean XtIsSensitive(w)
Widget w;
ARGUMENTS
sensitive Specifies a Boolean value that indicates whether the widget
should receive keyboard and pointer events.
w Specifies the widget.
DESCRIPTION
The function first calls on the current widget with an argument list
specifying that the sensitive field should change to the new value. It
then recursively propagates the new value down the managed children
tree by calling on each child to set the ancestor_sensitive to the new
value if the new values for sensitive and the child's ancestor_sensi‐
tive are not the same.
calls to change sensitive and ancestor_sensitive. Therefore, when one
of these changes, the widget's set_values procedure should take what‐
ever display actions are needed (for example, greying out or stippling
the widget).
maintains the invariant that if parent has either sensitive or ances‐
tor_sensitive then all children have ancestor_sensitive
The function returns or to indicate whether or not user input events
are being dispatched. If both core.sensitive and core.ancestor_sensi‐
tive are returns otherwise, it returns
