如何获取 Qt QListWidget 中列出的已检查项目

Question

I've populated a QListWidget with a list of items and added a check box leaving everything unchecked.

for td in root.iter('testdata'):
    test_data = td.get('ins')
    item = QtGui.QListWidgetItem(test_data, self.listWidgetLabels)
    item.setFlags(item.flags() | QtCore.Qt.ItemIsUserCheckable)
    item.setCheckState(QtCore.Qt.Unchecked)

The user then clicks a few of the items in the QListItem and clicks a 'Generate File' button on the gui.

self.pushButtonGenerateFile.clicked.connect(self.generate_file)

I want to get a list of all the checked QListItems.

def generate_driver(self):
    test = self.listWidgetLabels.selectedItems()
    items = []
    checked_items = []
    for index in range(self.listWidgetLabels.count()):
        items.append(self.listWidgetLabels.item(index))

        for x in self.listWidgetLabels.selectedItems():
            checked.append(x.text())
    for i in checked:
        print("Checked Items: {0}".format(i))

What is above gets the selectedItem in the list. I've tried get checkState(), getChecked(), but they don't exist for QListWidget items.

Any clues are much appreciated.

Thanks,

John.

Answer 1

You need to check if checkState is actually Qt.Checked :

for index in range(self.listWidgetLabels.count()):
    if self.listWidgetLabels.item(index).checkState() == Qt.Checked:
        checked_items.append(self.listWidgetLabels.item(index).text())

Answer 2

The above answer is close, missed the .text()<\/strong> . I'm not worthy to comment so the correction is as follows:

checked_items.append( self.listWidgetLabels_fields.item(index).text())
