Must be valid , and the same object , as long as this view is added to any slide show . /** This method clears the whole view area. The slide show uses this method to fully erase the view content . Since the slide show has no notion of view size , this is the only reliable way to wholly clear the view . void clear();/** Query the current transformation matrix for this view.<p> This method returns the transformation matrix of the view . When notified via the transformation change listener , the show will be displayed using the new transformation . < p > @ return the view transformation matrix . Note that the slide show itself will paint all slides as one - by - one boxes , one therefore has to at least provide a scaling at this matrix to blow this up to the desired device pixel size ( 640 times 480 , or whatever size the output view has ) . Furthermore , the aspect ratio of the scaling should match that of the slides ( otherwise , the slides will be scaled anisotropically ) . /** Query the current translation offset used to fill the physical screen while keeping aspect ratio.<p> This method returns the translation offset of the view of the view . < p > @ return the slideshowview will be transformed in order to fill the physical screen while keeping the aspect ratio . In order to do so , we need to add a black border on the side . This method return an IntegerSize2D which represent ( x , y ) translation . x represents the width of the border on the left , for example . /** Add a listener to get notified when the transformation matrix changes.<p> This method registers a listener with the view , which will get called every time the transformation matrix changes . < p > @ param xListener Listener interface to call when the transformation matrix changes . void addTransformationChangedListener( [in] ::com::sun::star::util::XModifyListener xListener );/** Revoke a previously registered transformation matrix change listener.<p> @ param xListener Listener interface to revoke from being called . void removeTransformationChangedListener( [in] ::com::sun::star::util::XModifyListener xListener );/** Add a listener to get notified when this view needs a repaint.<p> This method registers a listener with the view , which will get called every time the view needs an update of their screen representation . < p > @ param xListener Listener interface to call when the view needs a repaint . void addPaintListener( [in] ::com::sun::star::awt::XPaintListener xListener );/** Revoke a previously registered paint listener.<p> @ param xListener Listener interface to revoke from being called . void removePaintListener( [in] ::com::sun::star::awt::XPaintListener xListener );/** Add a mouse listener to the view.<p> This method registers a listener with the view , which will get called every time the mouse is clicked on the view . < p > @ param xListener Listener interface to call when the mouse is clicked on the view . void addMouseListener( [in] com::sun::star::awt::XMouseListener xListener );/** Revoke a previously registered mouse listener.<p> @ param xListener Listener interface to revoke from being called . void removeMouseListener( [in] com::sun::star::awt::XMouseListener xListener );/** Add a mouse motion listener to the view.<p> This method registers a listener with the view , which will get called every time the mouse is moved on the view . < p > @ param xListener Listener interface to call when the mouse is moved on the view . void addMouseMotionListener( [in] com::sun::star::awt::XMouseMotionListener xListener );/** Revoke a previously registered mouse move listener.<p> @ param xListener Listener interface to revoke from being called . void removeMouseMotionListener( [in] com::sun::star::awt::XMouseMotionListener xListener );/** Change the mouse cursor currently in effect.<p> This method changes the mouse cursor currently in effect , for this view . < p > @ param nPointerShape New mouse cursor shape to display for this view .
