Detailed Description

Wrapper around a shared canvas that forwards most of its methods to the shared canvas.

Most notable differences are:

The transformation of the ViewState of forwarded calls is modified by adding an offset.
The clip polygon of the ViewState of forwarded calls is intersected with a clip rectangle that can be set via SetClip().
Calls to updateScreen() are collected. One call to the updateScreen() method of the shared canvas is made asynchronously.

The canvas can use different canvases for sharing and for sprite construction. This allows the shared canvas to be a canvas of sprite itself.

Constructor & Destructor Documentation

◆ PresenterCanvas() [1/2]

sd::presenter::PresenterCanvas::PresenterCanvas	(	const css::uno::Reference< css::rendering::XSpriteCanvas > &	rxUpdateCanvas,
		const css::uno::Reference< css::awt::XWindow > &	rxUpdateWindow,
		const css::uno::Reference< css::rendering::XCanvas > &	rxSharedCanvas,
		const css::uno::Reference< css::awt::XWindow > &	rxSharedWindow,
		const css::uno::Reference< css::awt::XWindow > &	rxWindow
	)

This constructor is used when a PresenterCanvas object is created directly, typically by the PresenterCanvasFactory.

Parameters

rxUpdateCanvas	This canvas is used to call updateScreen() at and to create sprites. In the typical case this canvas is identical to the rxSharedCanvas argument.
rxUpdateWindow	The window that belongs to the canvas given by the rxUpdateCanvas argument.
rxSharedCanvas	The canvas that is wrapped by the new instance of this class. Typically this is a regular XSpriteCanvas and then is identical to the one given by the rxUpdateCanvas argument. It may be the canvas of a sprite which does not support the XSpriteCanvas interface. In that case the canvas that created the sprite can be given as rxUpdateCanvas argument to allow to create further sprites and to have proper calls to updateScreen().
rxSharedWindow	The window that belongs to the canvas given by the rxSharedCanvas argument.
rxWindow	The window that is represented by the new PresenterCanvas object. It is expected to be a direct descendant of rxSharedWindow. Its position inside rxSharedWindow defines the offset of the canvas implemented by the new PresenterCanvas object and rxSharedCanvas.
