XtUngrabPointer() XtUngrabPointer() Name XtUngrabPointer - release an active pointer grab. Synopsis void XtUngrabPointer(widget, time) Widget widget; Time time; Inputs widget Specifies the widget which has the active pointer grab. time Specifies the time at which the grab should end. CurrentTime is acceptable. Availability Release 4 and later. Description XtUngrabPointer() releases an active pointer grab by calling XUngrabPointer() with the display of w and time. The time argument may be a timestamp or the constant CurrentTime. If this time is earlier than the last-keyboard-grab time or later than the current server time the keyboard will not be ungrabbed. See XtGrabPointer() for more information on active pointer grabs. Usage Most applications will never have to issue a pointer grab. Note that the pointer is automatically grabbed between every button down event and the corresponding button up event; this covers the case for which pointer grabs are most commonly needed.
