protectedvirtual
virtual TouchState iview::CParallelogramShape::IsTouched ( istd::CIndex2d  position) const
virtual

Check, if any shape is touched.

When shape is touched, it return also pointer to this shape.

Returns
touch state for the shape, or iview::IInteractiveShape::TS_NONE, when nothing found.

Reimplemented from iview::CShapeBase.

virtual bool iview::CParallelogramShape::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
modelPtrpointer to model object being attached.
changeMaskoutput parameter returning set of change ID's will be accepted. returns a false.

Reimplemented from iview::CInteractiveShapeBase.

virtual bool iview::CParallelogramShape::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).
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::CInteractiveShapeBase.

virtual bool iview::CParallelogramShape::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.
