如何使窗口在pyqt5中不可移动

Question

我想“锁定”我的界面，以便用户无法从其位置移动窗口，我该怎么做？

到目前为止，我只找到了可以设置为setFloating(False)的QDockWidg类

但是我怎么能用下面的窗口做到这一点呢？

import sys

import os
import sys
from PyQt5 import QtWidgets as qtw
from PyQt5 import QtCore as qtc
from PyQt5 import QtGui as qtg



class Example(qtw.QWidget):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        # your code will go here


        vlayout = qtw.QVBoxLayout()
        hlayout = qtw.QHBoxLayout()

        heading = qtw.QLabel("wählen")
        self.test_button1 = qtw.QRadioButton("test1")
        self.test_button2 = qtw.QRadioButton("test2")

        self.select_button = qtw.QPushButton("select")

        hlayout.addWidget(self.test_button1)
        hlayout.addWidget(self.test_button1)


        vlayout.addWidget(heading)
        vlayout.addLayout(hlayout)
        vlayout.addWidget(self.select_button)

        self.setLayout(vlayout)

        self.show()



if __name__ == '__main__':
    app = qtw.QApplication(sys.argv)
    w = Example()

    w.show()
    sys.exit(app.exec_())

例如，将toggled的信号连接到self.test_button1 。

[信号]void QAbstractButton::toggled(bool 检查)

每当可检查按钮更改其状态时，就会发出此信号。 如果按钮被选中，checked 为真，如果按钮未选中，则为假。

在on_off_func槽，检查的状态self.test_button1和设置所需的Flag 。 之后，一定要调用self.show () 。

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        # your code will go here


        vlayout = qtw.QVBoxLayout()
        hlayout = qtw.QHBoxLayout()

        heading = qtw.QLabel("wählen")
        self.test_button1 = qtw.QRadioButton("test1")
        self.test_button1.toggled.connect(self.on_off_func)          # +
        self.test_button2 = qtw.QRadioButton("test2")

        self.select_button = qtw.QPushButton("select")

        hlayout.addWidget(self.test_button1)
        hlayout.addWidget(self.test_button2)

        vlayout.addWidget(heading)
        vlayout.addLayout(hlayout)
        vlayout.addWidget(self.select_button)

        self.setLayout(vlayout)

        self.show()

    def on_off_func(self, checked):
        if checked:
            self.setWindowFlags(qtc.Qt.FramelessWindowHint)
        else:
            self.setWindowFlags(qtc.Qt.Window)
        self.show()

if __name__ == '__main__':
    app = qtw.QApplication(sys.argv)
    w = Example()
    w.show()
    sys.exit(app.exec_())
