问题
I currently have a QLabel that has some text in it. However when I put some text in it that exceeds its geometrical width then that extra text is not displayed. I do not want to enable wordwrap since I want the QLabel to expand horizontally. Is there anyway that Qlabel could increase its geometrical width based on its content.
回答1:
Call QWidget::adjustSize() everytime you change the content of your label. I can't elaborate on other possible answers due to lack of information, but that will probably do the trick.
