问题描述

如何使此窗口无边界(删除最小/最大化/关闭)?

How to make this window Border-less (remove minimize/maximize/close)?

  1 import sys
  2 from PyQt4 import QtCore, QtGui
  3 from qt import Ui_MainWindow
  4 
  5 class StartQT4(QtGui.QMainWindow):
  6     def __init__(self, parent=None):
  7         QtGui.QWidget.__init__(self, parent)
  8         self.ui = Ui_MainWindow()
  9         self.ui.setupUi(self))
 10         
 11 if __name__ == "__main__":
 12     app = QtGui.QApplication(sys.argv)
 13     myapp = StartQT4()
 14     myapp.show()
 15     app.setWindowFlags(app.FramelessWindowHint) <<< does not working
 16     sys.exit(app.exec_())
 17     

推荐答案

在主窗口上调用show之前，需要设置窗口标志.

You need to set the window flag before calling show on the main window.

一个最小的工作示例如下:

A minimal working example would look like this:

import sys
from PyQt4 import QtCore, QtGui

class StartQT4(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super(StartQT4, self).__init__(parent)
        self.setWindowFlags(QtCore.Qt.FramelessWindowHint)
        self.b = QtGui.QPushButton("exit", self, clicked=self.close)

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = StartQT4()
    myapp.show()
    sys.exit(app.exec_())
