NAME

VObject::Input - instance method

TEMPLATE

commandToPerform = Command * Input(Point locatorPoint, Token inputToken, Clipper * focusClipper)

SPECIFIERS

public virtual

DESCRIPTION

Input checks whether an event can be consumed at all by this. If this VObject contains the locatorPoint (see method ContainsPoint) and it is enabled, then the event is passed to the method DispatchEvents and the command is returned. If this doesn't contain the locatorPoint, then NULL is returned. Method is rarely overridden.

ARGUMENTS

Point locatorPoint: see method DispatchEvents
Token inputToken: see method DispatchEvents
Clipper * focusClipper: see method DispatchEvents

RETURN ARGUMENT

Command * commandToPerform: contains a command to be executed by one of the next event handlers. A Document will usually execute the command (see method Document::PerformCommand). If the inputToken has not been handled or this is disabled then gNoChanges is returned. If this doesn't contain the locatorPoint at all then NULL is returned.

FIRST DEFINITION

class VObject

FILES

implementation:: VObject.C

KNOWN PROBLEMS

A VObject should not get input events if it is closed (flag eVObjOpen, see enum VObjFlags). But this test is commented out in the code. See method VObject::Input.
