Default C++ constructor which creates an invalid blank-window handle.

See RWindowTreeNode::RWindowTreeNode() for details of how the complete setup of a handle field may be deferred until the window server session is known.

Default C++ constructor which creates a valid but uninitialised blank-window handle.

This constructor does not create a window in the window server: client programs must do this by calling RBlankWindow::Construct() before any operations can be carried out on the window.

Completes the construction of a valid blank-window handle.

This function should be called after the RBlankWindow(RWsSession&) constructor, and before any other functions are performed on the window. It creates a window in the window server corresponding to the RBlankWindow object. The window is initialised to inherit the size and extent of its parent window, or to be full screen if its parent is a group window.

This function always causes a flush of the window server buffer.
