Selecting various BKS_ notebook styles together with setting the window orientation to right-to-left can be used to construct a notebook which resembles a right-to-left notebook.
When the notebook control has RtL window orientation, the page arrows have their roles reversed: the left arrow turns the pages forwards, whereas the right one - backwards. The text of Tabs, and Status line is converted according to their Bidi Attributes.
For Arabic, mnemonic specified in TABs are normalized to their base shapes.
The notebook control processes the views of its internal objects (Tabs, Status-Line and Page-Arrows) according to their bidi attributes. Applications are responsible for processing the views of their own page components (e.g dialog controls) by setting the appropriate bidi attributes to these components.
The internal objects use the bidi attributes of the notebook window, unless their bidi attributes are specifically set using one of the following messages:
Applications can query the bidi attributes of their tabs and status-line page components using the following messages:
When the notebook control receives the WM_SETBIDIATTR message it modifies its own bidi attributes (and as a result - its appearance).
