如何创建复选框列表 [英] How to create a list of checkboxes

问题描述

我正在尝试读取xml文件，并使用其中的某些内容填充 QListWidget 。每个条目应具有一个复选框。

I'm trying to read in an xml file and populate a QListWidget with some of its contents. Each entry should have a checkbox.

在Qt Designer中，我创建了列表，并添加了一个具有复选框的项目，方法是将该项目添加到listWidget，然后右键单击它并选择编辑项目>属性>将标志设置为UserCheckable。因此，我可以手动完成。

In Qt Designer I created the list and added an item that has a checkbox by adding the item to the listWidget, then right clicking on it and selecting Edit Items > Properties > Set Flags to UserCheckable. So i can do it manually.

但是当我读取xml文件以填充ListWidget时，我无法使这些项目可检查。

But when I read in the xml file to populate the ListWidget I can't make these items checkable.

import xml.etree.ElementTree as et

xml_file = os.path.join(path, testcase_file)
tree = et.parse(xml_file)
root = tree.getroot()

for testcases in root.iter('testcase'):
    testcase_name = str(testcases.attrib)
    item = self.listWidgetTestCases
    item.addItem(QtGui.QApplication.translate("qadashboard", testcase_name, None))
    # item.setFlags(item.flags() | QtCore.Qt.ItemIsUserCheckable)
    # item.setCheckState(QtCore.Qt.Unchecked)

列表小部件中测试用例名称的列表。但是，我无法将这些项目放入复选框。列表小部件无法识别 item.setFlags 或 ItemIsUserCheckable ，因此在上面的示例中注释了两行。

This creates a list of test case name in the list-widget. However I can't make these items into checkboxes. item.setFlags or ItemIsUserCheckable is not recognised for list Widgets, so the two lines are commented out in the above example.

推荐答案

您快到了：只是您要制作列表小工具可检查，而不是每个列表小部件。

You're almost there: it's just that you're trying to make the list-widget checkable, rather than each list-widget-item.

尝试以下操作：

from PyQt5 import QtWidgets, QtCore

self.listWidgetTestCases = QtWidgets.QListWidget()

for testcases in root.iter('testcase'):
    testcase_name = str(testcases.attrib)

    item = QtWidgets.QListWidgetItem(testcase_name)
    item.setFlags(item.flags() | QtCore.Qt.ItemIsUserCheckable)
    item.setCheckState(QtCore.Qt.Unchecked)
    self.listWidgetTestCases.addItem(item)

（注意：对于PyQt4，请使用QtGui而不是QtWidgets）

(NB: for PyQt4, use QtGui instead of QtWidgets)
