如何在pyqt中创建模态窗口?

How to create a modal window in pyqt?(如何在pyqt中创建模态窗口?)

问题描述

我查看了文档，发现self.setWindowModality(QtCore.Qt.WindowModal)".
我将此函数添加到我的init"函数中，但仍然无法创建模态对话框.

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 has setModal() as found 此处.

QDialog has setModal() as found here.

如文档所述:

默认情况下，该属性为 False 并且 show() 弹出对话框如下无模式.将此属性设置为 true 相当于设置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 sebastian 提到的也是一个 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.
