“text-overflow” for a QLabel’s text rendering

Question

I have got a QLabel in a widget which can be resized. The text can overflow boundaries, so I need, for the application to look more elegant, some way to make the text generate an ellipsis (...) after the last totally visible word in the text.

Making layouts in HTML/CSS I used to use text-overflow: ellipsis; for this, but for Qt classes, I have not found any information on this.

It looks like in your label's resize event, you can create elided text using the new width of the widget, and reset the text. Use QFontMetrics::elidedText method to get the elided version of the string.

QString text("some long text without elipsis");
QFontMetrics metrics(label->font());
QString elidedText = metrics.elidedText(text, Qt::ElideRight, label->width());
label->setText(elidedText);
