18.4.3 FORMS Objects
Besides methods specific to particular kinds of FORMS objects, all
FORMS objects also have the following methods:
FORMS objectset_call_back(function, argument)
- Set the object's callback function and argument. When the object
needs interaction, the callback function will be called with two
arguments: the object, and the callback argument. (FORMS objects
without a callback function are returned by fl.do_forms()or fl.check_forms() when they need interaction.) Call this
method without arguments to remove the callback function.
FORMS objectdelete_object()
- Delete the object.
FORMS objectshow_object()
- Show the object.
FORMS objecthide_object()
- Hide the object.
FORMS objectredraw_object()
- Redraw the object.
FORMS objectfreeze_object()
- Freeze the object.
FORMS objectunfreeze_object()
- Unfreeze the object.
FORMS objects have these data attributes; see the FORMS documentation:
