How to create a modal window in pyqt?
提问by user3135832
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.
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。
Any help will be appreciated,
Thank You.
任何帮助将不胜感激，
谢谢。

QDialoghas setModal()as found here.
QDialog已setModal()找到here。
As the docs state:
正如文档所述：
By default, this property is
Falseandshow()pops up the dialog as modeless. Setting this property to true is equivalent to settingQWidget.windowModalitytoQt.ApplicationModal.
默认情况下，这个属性是
False和show()弹出的对话框与非模态。将此属性设置为 true 等同于设置QWidget.windowModality为Qt.ApplicationModal。
As @sebastian noted you could use exec(). However it is better to use exec_()as the one sebastian mentioned is also a python call.
正如@sebastian 指出的那样，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。
Example:
例子：
my_dialog = QDialog(self)
my_dialog.exec_() # blocks all other windows until this window is closed.
If this doesn't help please post your code and I will have a look.
如果这没有帮助，请发布您的代码，我会看看。
