QTextEdit pagescroll
Message 1 in thread
Hi list,
[Qt-4.3.4]
A QTextEdit can be scrolled down by a page by issuing:
QTextEdit::moveCursor(QTextEdit::MovePageDown);
but that's a Qt3 support function.
The documentation suggests to use the QTextCursor class instead.
OK, but QTextCursor apparently doesn't have the concept of a page.
There is an enum QTextCursor::MoveOperation that has moves by
characters, lines, words, blocks, but not pages.
Am I missing something? How should one proceed to translate that
moveCursor() call to Qt4 without QT3_SUPPORT?
Thanks,

PageUp & PageDown really depends on how many lines are visible in the
control. Once you get that number then use MoveOperation by number of lines
visible - 1 or -2 (if there is only 1 or 2 lines visible then you really
navigate only 1 or 2 lines).
