[FIXED] How to change the caption of a button in a QDialogButtonBox?

Issue

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.

Solution

You will have to do some 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(QDialogButtonBox.Ok).setText("Run")
self.ui.buttonBox.button(QDialogButtonBox.Cancel).setText("Cancel")

Also, as pointed out by @Kuba Ober, changing the text of standard buttons is not the best approach. The most correct way is to add custom buttons with an appropriate role.

self.ui.buttonBox.addButton("Run", QDialogButtonBox.ActionRole)
