Pyqt5保持窗體在前臺

關鍵代碼

from PyQt5.QtWidgets import QApplication, QMainWindow
import PyQt5.QtCore

myWin.setWindowFlags(PyQt5.QtCore.Qt.WindowMinimizeButtonHint |  # 使能最小化按鈕
                         PyQt5.QtCore.Qt.WindowCloseButtonHint |  # 使能關閉按鈕
                         PyQt5.QtCore.Qt.WindowStaysOnTopHint)  # 窗體總在最前端

 

例如

if __name__ == '__main__':
    app = QApplication(sys.argv)
    myWin = MyWindow()
    myWin.pushButton.clicked.connect(myWin.Refrensh)
    myWin.pushButton_2.clicked.connect(myWin.Main_to)
    myWin.setWindowFlags(PyQt5.QtCore.Qt.WindowMinimizeButtonHint |  # 使能最小化按鈕
                         PyQt5.QtCore.Qt.WindowCloseButtonHint |  # 使能關閉按鈕
                         PyQt5.QtCore.Qt.WindowStaysOnTopHint)  # 窗體總在最前端
    myWin.show()
    myWin.comboBox.addItems(myWin.GetAllWinHwn().keys())
    sys.exit(app.exec_())

就是可以使窗體一直保持在前臺顯示啦
