Making only one column of a QTreeWidgetItem editable

You can make only certain columns in a QTreeWidget editable using a workaround:

1) Set the editTriggers property of the QTreeWidget to NoEditTriggers

2) On inserting items, set the Qt:ItemIsEditable flag of the QTreeWidgetItem object

3) Connect the following slot to the “itemDoubleClicked” signal of the QTreeWidget object:

void MainWindow::onTreeWidgetItemDoubleClicked(QTreeWidgetItem * item, int column)
{
    if (isEditable(column)) {
        ui.treeWidget->editItem(item, column);
    }
}

where “isEditable” is a function you wrote that returns true for editable columns and false for non-editable columns.
