Python：如何使QGroupBox無邊界

Question

需要設置什麼QGroupBox屬性來隱藏其邊框？

from PyQt4 import QtGui, QtCore 
import sys, os 


class Dialog_01(QtGui.QMainWindow): 
    def __init__(self): 
     super(QtGui.QMainWindow,self).__init__() 

     mainWidget=QtGui.QWidget() 
     self.setCentralWidget(mainWidget) 
     mainLayout = QtGui.QVBoxLayout() 
     mainWidget.setLayout(mainLayout) 

     tabWidget = QtGui.QTabWidget() 
     mainLayout.addWidget(tabWidget) 

     WidgetA = QtGui.QWidget() 
     LayoutA = QtGui.QVBoxLayout() 
     WidgetA.setLayout(LayoutA) 

     GroupBox1 = QtGui.QGroupBox('Goupbox 1') 
     Layout1 = QtGui.QHBoxLayout() 
     GroupBox1.setLayout(Layout1) 
     LayoutA.addWidget(GroupBox1) 

     GroupBox2 = QtGui.QGroupBox('Goupbox 2') 
     Layout2 = QtGui.QHBoxLayout() 
     GroupBox2.setLayout(Layout2) 
     Layout1.addWidget(GroupBox2) 

     GroupBox3 = QtGui.QGroupBox('Goupbox 3') 
     Layout3 = QtGui.QHBoxLayout() 
     GroupBox3.setLayout(Layout3) 
     Layout2.addWidget(GroupBox3) 

     tabWidget.addTab(WidgetA,'A')  

     tabWidget.addTab(QtGui.QWidget(),'B') 
     tabWidget.addTab(QtGui.QWidget(),'C') 



if __name__ == '__main__': 
    app = QtGui.QApplication(sys.argv) 
    dialog_1 = Dialog_01() 
    dialog_1.show() 
    dialog_1.resize(480,320) 
    sys.exit(app.exec_())

你可以嘗試QGroupBox.setFlat，但具體結果將在當前使用依賴於窗口小部件的風格。
