如何使窗口在pyqt5中不可移動

Question

我想“鎖定”我的界面，以便用戶無法從其位置移動窗口，我該怎么做？

到目前為止，我只找到了可以設置為setFloating(False)的QDockWidg類

但是我怎么能用下面的窗口做到這一點呢？

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，將toggled的信號連接到self.test_button1 。

[信號]void QAbstractButton::toggled(bool 檢查)

每當可檢查按鈕更改其狀態時，就會發出此信號。 如果按鈕被選中，checked 為真，如果按鈕未選中，則為假。

在on_off_func槽，檢查的狀態self.test_button1和設置所需的Flag 。 之后，一定要調用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()

    app = qtw.QApplication(sys.argv)

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