Minimum QGroupBox size

[klnusbaum]

I have a QGroupBox that I initially set up with a given title. Through out the program, based on certain user inputs, this QGroupBox gets resized. Sometimes the title of QGroupBox can be slightly long, and sometimes when the QGroupBox is resized to a smaller size the title can get cut off. Can anyone think of a way to set a minimum width on the QGroupBox which would ensure the full title will always be displayed in its entirety?

After changing the title try a:


QFontMetrics fm(group->font());
int minW = fm.width(group->title());
group->setMinimumWidth(minW);

Thanks for the suggestion Marcel. It doesn't quite seem to work though. I think I was a little unclear in my stating of the problem though. The title is set when the QGroupBox is constructed. It doesn't changed. The only thing about the QGroupBox that changes is its size. Does that change the problem a little bit?

Here's my attempt to implement the suggested code:


ETGroupBox::ETGroupBox(const QString &title, QWidget *parent):QGroupBox(parent){
setTitle(title);
theGrid = new QGridLayout();
setLayout(theGrid);
QFontMetrics fm(this->font());
int minW = fm.width(this->title());
setMinimumWidth(minW);
}

I've tried messing around with the QFontMetrics, but I still can't quite seem to get it. In fact, it seems like for some reason, my QGroupBox won't respect any minimum width I set for it. If I call resize(sizeHint()) on it, it doesn't seem to be respecting the minimum width.
