【问题描述】:
QTableView 被指定为 QAbstractTableModel 作为模型。并且ItemDelegate(QItemDelegate) 被分配了tableView.openPersistentEditor。现在,当点击 tableView 时,事件不会一直传播到 tableView(它是否被委托的QLineEditor 阻止)。
有什么方法可以传递 QLineEdit'smousePressEventevent that is passed through theItemDelegatetoQTableView 的 modelwhen the tableView's item is clicked even while it is occupied byQItemInstance? Is there anyQItemDelegate` 标志来完成任务?
代码创建了一个带有模型和委托的 tableView。 通过单击第 0 列或第 1 列触发的事件不会传播到 tableView 的项目,因为该项目保持取消选中状态。
取消注释带有tableView.setSelectionBehavior(QtGui.QTableView.SelectRows) 的行可以解决问题。是吗?
