使用python迭代QListView中的所有项目 [英] Iterating all items inside QListView using python

问题描述

我有一个 QlistView 里面有一个复选框(动态创建)和项目名称(QstandardItem).Qlistview 下面是一个名为 DatacheckercheckBox1 的复选框.我想要的是当此 DatacheckercheckBox1 复选框状态更改为已选中"时，应选中 QlistView 中的所有复选框.我已通过

I have a QlistView inside is which a checkboxes (created dynamically) with item name (QstandardItem). And below Qlistview is a checkbox named DatacheckercheckBox1. What I want is when this DatacheckercheckBox1 checkbox statechanges to "Checked", all the checkboxes inside the QlistView should be checked. I have made a signal for DatacheckercheckBox1 checkbox by

self.dlg.DatacheckercheckBox1.stateChanged.connect(self.selectAll)

我不知道编写一个方法来迭代 Qlistview 中的所有项目，如果尚未选中，则将其旁边的复选框设为已选中".

i dont have idea in writing a method that should iterate all the items inside Qlistview and make the checkboxes next to it "Checked" if its not checked already.

推荐答案

使用模型迭代项目:

model = self.listView.model()
for index in range(model.rowCount()):
    item = model.item(index)
    if item.isCheckable() and item.checkState() == QtCore.Qt.Unchecked:
        item.setCheckState(QtCore.Qt.Checked)
