This interface is a collection of functions that are necessary to
implement larger parts of the presenter screen as extension. The
methods of this interface give access to services that can, at the
moment, only implemented in the Office core, not in an extension.
With time some, maybe all, methods can moved to other, better suited,
interfaces.
Create a new canvas for the given window. The new canvas is a
wrapper around the given shared canvas. The wrapper only modifies
the origin in all output and clipping methods.
Capture the mouse so that no other window will receive mouse events.
Note that this is a potentially dangerous method. Not calling
releaseMouse eventually can lead to an unresponsive application.
Create a new window as child window of the given parent window.
Parameter xParentWindow
The parent window of the new window.
Parameter bCreateSystemChildWindow
When true then the new window will be a system window that,
in the context of the presenter screen, can not be painted over
by other windows that lie behind it.
Parameter bInitiallyVisible
When true the new window will be visible from the start,
i.e. a window listener will not receive a windowShown signal.
Parameter bEnableChildTransparentMode
When true the parent window is painted behind its child
windows. This is one half of allowing child windows to be
transparent.
Parameter bEnableParentClip
When true then the parent window is not clipped where its
child windows are painted. This is the other half of allowing
child windows to be transparent.
Create a new canvas for the given window. The new canvas is a
wrapper around the given shared canvas. The wrapper only modifies
the origin in all output and clipping methods.
Parameter xUpdateCanvas
This canvas is used to call updateScreen() on. May be NULL
Parameter xUpdateWindow
The window that belongs to the update canvas. May also be
NULL (is expected to b NULL whenever xUpdateCanvas is.)
Parameter xSharedCanvas
The canvas that is shared by the wrapper.
Parameter xSharedWindow
The window of the shared canvas. This is used to determine the
proper offset.
Parameter xWindow
The canvas is created for this window. Must not be NULL
The canvas is created for this window. Must not be NULL
Parameter nRequestedCanvasFeatureList
List of requested features that the new canvas should (has to)
provide. Use only values from the CanvasFeature
constants group.
Parameter sOptionalCanvasServiceName
When an explicit service name is given then a new object of this
service is created. This service name lets the caller select a
specific canvas implementation, e.g. with or without hardware
acceleration.
Capture the mouse so that no other window will receive mouse events.
Note that this is a potentially dangerous method. Not calling
releaseMouse eventually can lead to an unresponsive application.
Parameter xWindow
The window for which mouse events will be notified even when the
mouse pointer moves outside the window or over other windows.
