NAME

VObject::TrackInContent - instance method

TEMPLATE

commandToPerform = Command * TrackInContent(Point locatorPoint, Token inputToken, Command * tracker)

SPECIFIERS

public virtual

DESCRIPTION

The method DispatchEvents calls TrackInContent for its focusClipper argument with the tracker command returned by the method DoLeftButtonDownCommand or the method DoMiddleButtonDownCommand.
The default implementation just returns the tracker. Only the class Clipper overrides this method. The method Clipper::TrackInContent tracks the mouse and calls the tracking methods of the tracker during the different track phases such as mouse button pressed, mouse moved and button released. Method is rarely overridden.

ARGUMENTS

Point locatorPoint: see method DispatchEvents
Token inputToken: see method DispatchEvents
Command * tracker: a mouse tracking command which should have its Track... methods overridden

RETURN ARGUMENT

Command * commandToPerform: the final command to perform or gNoChanges. In most of the cases this command is identical to tracker but it need not be. It is possible to perform mouse tracking with one command and during or after tracking replace it with another undoable command.
