问题 I want to allow a user using my application to be able to drag a boundary between two widgets in my window which will resize the two (i.e. you drag it down and the top one will get bigger while the bottom gets smaller, and vice-versa). Is there anything in Qt designer that will allow a user to resize an element in the window, within certain constraints? Thank you 回答1: What you're describing is called a QSplitter widget.

How to change the caption of a button in a QDialogButtonBox?

阅读更多关于 How to change the caption of a button in a QDialogButtonBox?

I have added a QDialogButtonBox button with the default Cancel and OK buttons. Is there a way to change the caption of these buttons? For example, OK should become Run . You will have to do some slight coding in your cpp file: ui->buttonBox->button(QDialogButtonBox::Ok)->setText("Run"); ui->buttonBox->button(QDialogButtonBox::Cancel)->setText("Exit"); Note that you may also need to include the QPushButton header: #include <QPushButton> Update: Did not notice the pyqt tag. I'm not familiar with Python (and PyQt in particular), but I think this should do the job: self.ui.buttonBox.button
