[Qt-interest] Qt4.4 QTextEdit size and viewport() size

[Malyushytsky, Alex]

>>MyTextEdit->document().size() doesn't return the actual size of the
'underlying widget'

Just some thoughts. I guess it depends when it is called and is this document diplayed in a several views or not.
I would expect, that if document is already displayed in the MyTextEdit, the appropriate layout is set and document().size().height() should give you an appropriate value.

If not you probably can do such initialization yourself.
But it might be just easier to call document().size() at proper time, than handle all initialization yourself.

I have not tried anything above, so I can't be sure, but this is how I expect it works:
QTextEdit invokes QAbstractTextDocumentLayout::draw to draw QTextDocument in the viewport.
According QT4 documentation QTextDocument::document().size()is equivalent to documentLayout()->documentSize();


Hope this helps,

Thanks for the pointer. It looked promising, but unfortunately,
MyTextEdit->document().size() doesn't return the actual size of the
'underlying widget'.
