PyQt设置一行QComboBox的启用属性

问题描述

如何设置 QComboBox 中一行的 enabled 属性?我希望它有一些禁用和一些启用的行.

How can I set the enabled property of a row of a QComboBox? I want it to have some disabled and some enabled rows.

推荐答案

这是一个 QComboBox 的工作示例，其中第 1 项和第 4 项(在列表 disable 中指定)被禁用.我使用了 this 示例.另请参阅 setData 方法的文档.

Here is a working example of a QComboBox, where items 1 and 4 (as specified in the list disable) are disabled. I used this example. See also the documentation for the setData method.

from PyQt4 import QtCore, QtGui
import sys

class Foo(QtGui.QMainWindow):
    def __init__(self):
        QtGui.QMainWindow.__init__(self)

        items = ['foo', 'bar', 'yib','nuz', 'pip', 'rof']
        cb = QtGui.QComboBox(self)
        for i in items:
            cb.addItem(i)

        disable = [1,4]
        for i in disable:
            j = cb.model().index(i,0)
            cb.model().setData(j, QtCore.QVariant(0), QtCore.Qt.UserRole-1)

if __name__ == "__main__":
    app = QtGui.QApplication([])
    foobar = Foo()
    foobar.show()
    sys.exit(app.exec_())
