Detailed Description

a2dScaledEndLine

The begin and end object on the line are scaled to the contour width. In case of a a2dArrow derived object, rendering is optimized to look good. All types of end objects are scalled up m_contourwidth. If m_contourwidth is zero, there will be no endpoints drawn.

bool a2dScaledEndLine::DoUpdate	(	UpdateMode	mode,
		const a2dBoundingBox &	childbox,
		const a2dBoundingBox &	clipbox,
		const a2dBoundingBox &	propbox
	)			[protected, virtual]

Update derived Object specific things ( mainly boundingbox).

Calculates the boundingbox of the object (exclusif base class child objects but with other nested objects).

Parameters:

	mode	way to update the objects
	childbox	size of children boundingbox
	clipbox	clip to this
	propbox	size of properties boundingbox

Remarks:

in a derived class this function can also be used to update object specific cache data.

force may or may not have direct influence on the object itself, if this function is called directly for some reason (e.g from derived objects), you must invalidate the boudingbox yourself. GetDrawerBox()->SetValid( false );

Reimplemented from a2dEndsLine.

void a2dScaledEndLine::DoRender	(	a2dIterC &	ic,
		OVERLAP	clipparent
	)			[protected, virtual]

render derived object

if the object has sub objects (apart from the childobject which are handled here), those subobject most rendered by iterating on layer when needed/wanted, simular to child objects. We do not iterate here, since that is only needed if indeed there or subobjects. This will be know in a "wxDerivedCanvasObject DoRender".

SO parent objects that call this function, must:

• 1- clip object against area to redraw.
• 2- iterate on layers when needed.

A a2dCanvasObject is rendered as a + (plus sign) when there or no children.

Reimplemented from a2dEndsLine.
