Support visual cursor movement for BIDI text
Bidi input can in some contexts be more intuitive if the cursor
works in visual way: pressing left arrow key always make cursor
move one character to the left regardless the language of text,
pressing right arrow key always make cursor move to the right.
It is also the behavior of Mac OS X. Based on the above reason
and requests from Symbian we implemented this support for visual
movement in BIDI text. 3 public properties are added to
QTextDocument, QTextLayout and QLineEdit respectively:
- QTextDocument::defaultCursorMoveStyle can be used to control
the cursor behavior in all widgets based on QTextDocument,
like QTextEdit, QPlainTextEdit, etc. When set to QTextCursor::
Visual, it will enable visual movement for all the cursors in
the corresponding text edit. Default is QTextCursor::Logical.
- QTextLayout::cursorMoveStyle is used for low-level cursor
manipulation. When set to Visual, it will enable visual movement
behavior for all the cursor related methods, including cursorToX,
xToCursor and drawCursor. Default is Logical.
- QLineEdit::cursorMoveStyle is used to control cursor movement
behavior in QLineEdit. Default is Logical.:
