PyQT QTreeWidget iterating

I have two columns in a QTreeWidget, one column represents a list of urls and the second represents results. I have loaded the list of urls in first column and now I want to iterate this list and during the iteration, change the text in the second column. How to achieve this?

Solution

  • You can call QTreeWidget.invisibleRootItem() to receive the root item, and then use the QTreeWidgetItem API to iterate through the items.

    Example:

    root = self.treeWidget.invisibleRootItem()
child_count = root.childCount()
for i in range(child_count):
    item = root.child(i)
    url = item.text(0) # text at first (0) column
    item.setText(1, 'result from %s' % url) # update result column (1)

    I am assuming self.treeWidget is populated by:

    self.treeWidget.setColumnCount(2) # two columns, url result
for i in range(10):
    self.treeWidget.insertTopLevelItem(i, QTreeWidgetItem(QStringList('url %s' % i)))
