QText Edit help please

[munna]

Hi,

Is there a way by which we can find the minimum height of a QTextEdit such that the vertical scrollbar will not appear ?

Alternately, is there a way to find the total number of lines of text available in QTextEdit?
Using this info and QFontMetrics we can probably find the ideal height.

Thanks a lot

txtEdit->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);

OR


QSize size = txtEdit->minimumSize ();
int minHeight = size.height ();

if(txtEdit->height () == minHeight())
{
txtEdit->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysO ff);
}

QAbstractTextLayout::documentSize() should work. You can access the layout using QTextDocument::documentLayout().
