问题描述

我添加了一个带有默认 Cancel 和 OK 按钮的 QDialogBu​​ttonBox 按钮.

I have added a QDialogButtonBox button with the default Cancel and OK buttons.

有没有办法更改这些按钮的标题?例如，OK 应该变成 Run.

Is there a way to change the caption of these buttons? For example, OK should become Run.

推荐答案

您必须在 cpp 文件中进行一些轻微的编码:

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");

请注意，您可能还需要包含 QPushButton 标头:

Note that you may also need to include the QPushButton header:

#include <QPushButton>

更新:

没有注意到 pyqt 标签.我不熟悉 Python(尤其是 PyQt)，但我认为这应该可以:

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")

此外，正如 Kuba Ober 所指出的，更改标准按钮的文本并不是最好的方法.最正确的方法是添加具有适当角色的自定义按钮.

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)
