For dialogue boxes, one usually wants to suspend the
application until the user responds to the dialogue. In particular,
one needs to suspend event processing on all widgets except the
dialogue. The latter can be achieved by using EZ_SetGrab
.
void EZ_SetGrab(EZ_Widget *widget); void EZ_ReleaseGrab(void);
EZ_SetGrab
sets a grab on widget
. It informs the EZ
event dispatcher to drop all events not associated with
widget
or its descendants. The grab, if set succesfully,
will remain in effect until either
EZ_ReleaseGrab
.
