Making a QTextEdit resize itself to fit its content

Message 1 in thread

Hi,

Sorry in advance, if this question was already answered somewhere.

I have a QTextEdit instance which I use to visualize a complex 
QTextDocument. My problem is that I would like very much to make the 
QTextEdit to resize itself as to fit its contents, is this possible ?

BTW , I am currently doing it by forcing the QTextEdit to show its 
scrollbars and getting the real 'height' and 'width' from the scrollbars 
maximum values. This works but I was wondering if exists some better, 
legal, way of doing it.

Thanks a lot.

Regards,
Hernán

Did you already tried setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded) and 
setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded) ?

I didn't try it but it wouldn't work because that property what it does, 
please someone correct me if I'm wrong, is to control when the 
scrollbars are shown, they don't do nothing with the size of the widget.

What I need is to being able to show a QTextEdit like we do with 
QLabels, they just adjust their size to its contents.

Thanks

Hernán

tried

QTextBrowser::document()->documentLayout()->documentSize().toSize() ?

(Browser inherits edit, should work there as well, but i guess you're not 
interested in an editable widget anway)

Yes.

You could probably get the size from QTextDocument or something, but an 
easy solution would simply be QTextEdit::viewport()->size(). That one 
will give you the actual height of the content without any fiddling :-)

This (below) is a bit of a hack, but it seems to work.
