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.
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.
