如何在Pyqt中创建一个只读组合框？

我有一个组合框的项目，我只是想显示它们，而不能选择任何他们。我在Qt设计器中搜索，但我找不到合适的属性。有任何想法吗 ？

Answer 1

你不能做到这一点在QtDesigner你必须连接currentIndexChanged信号与功能将恢复无论用户选择旧值：

示例：

导入系统 来自PyQt4导入QtGui，QtCore

class MainWidget(QtGui.QWidget): 
    def __init__(self): 
     super(MainWidget, self).__init__() 
     # Create a combo and set the second item to be selected 
     self.combo = QtGui.QComboBox() 
     self.combo.addItems(['foo', 'bar', 'baz']) 
     self.combo.setCurrentIndex(1) 
     # Connect the combo currentIndexChanged signal 
     self.combo.activated.connect(self.on_combo_change) 
     # Setup layout 
     self.layout = QtGui.QVBoxLayout() 
     self.layout.addWidget(self.combo) 
     self.setLayout(self.layout) 

    def on_combo_change(self, index): 
     # Whatever the user do, just ignore it and revert to 
     # the old value. 
     self.combo.setCurrentIndex(1) 


app = QtGui.QApplication(sys.argv) 
mw = MainWidget() 
mw.show() 
app.exec_()

QComboBox.setEditable(False)应该这样做：http://pyqt.sourceforge.net/Docs/PyQt4/qcombobox.html#setEditable
