◆ OnModelAttached()

virtual bool iview::CLabelShape::OnModelAttached	(	imod::IModel *	modelPtr,
		istd::IChangeable::ChangeSet &	changeMask )

virtual

This call back function will be called, if an observable object is about to be attached.

This function returns a true, if observable object is accepted by the implementation logic of the observer, otherwise returns false.

Parameters

modelPtr	pointer to model object being attached.
changeMask	output parameter returning set of change ID's will be accepted. returns a `false`.

Reimplemented from iview::CPinShape.

◆ OnMouseButton()

virtual bool iview::CLabelShape::OnMouseButton	(	istd::CIndex2d	position,
		Qt::MouseButton	buttonType,
		bool	downFlag )

virtual

It is called, when mouse button is pushed down or up on this object.

Parameters

position	position of mouse pointer on client area (picture coords).
buttonType	determine the mouse butten type.
downFlag	true, if mouse button is pushed down, false if pushed up.

Returns: true if this shape should get focus to catch all mouse movements.

Reimplemented from iview::CPinShape.

◆ OnMouseMove()

virtual bool iview::CLabelShape::OnMouseMove ( istd::CIndex2d position )

virtual

It is called, when mouse is moved.

Only objects with focus receive this event.

Parameters

position - position of mouse pointer on client area (picture coords).

Returns: true if this shape should hold focus to catch longer all mouse movements.

Reimplemented from iview::CPinShape.
