如何在pyqt中创建模式窗口? [英] How to create a modal window in pyqt?

问题描述

我查看了文档，发现是'self.setWindowModality(QtCore.Qt.WindowModal)'.
我将此功能添加到了" init "功能中，但是仍然无法创建模式对话框.

I looked into the documentation and i found 'self.setWindowModality(QtCore.Qt.WindowModal)'.
I added this function to my 'init' function, but however still was not able to create a modal dialog box.

任何帮助将不胜感激，
谢谢.

Any help will be appreciated,
Thank You.

推荐答案

QDialog具有setModal()，已发现文档状态如下:

默认情况下，此属性为False，并且show()弹出对话框，如下所示: 无模式的.将此属性设置为true等同于设置 QWidget.windowModality到Qt.ApplicationModal.

By default, this property is False and show() pops up the dialog as modeless. Setting this property to true is equivalent to setting QWidget.windowModality to Qt.ApplicationModal.

正如@sebastian指出的，您可以使用exec().但是，最好使用exec_()，因为提到的一个塞巴斯蒂安也是python调用.

As @sebastian noted you could use exec(). However it is better to use exec_() as the one sebastian mentioned is also a python call.

示例:

my_dialog = QDialog(self) 
my_dialog.exec_()  # blocks all other windows until this window is closed.

如果这没有帮助，请发布您的代码，我会看看.

If this doesn't help please post your code and I will have a look.
