在tableview中 双击一个单元格 然后能弹出一个新界面 [复制链接]

是一个单元格  不是一行    我想每个单元格都对应各自的界面··· 求大神解答 谢谢

那就用void QAbstractItemView::doubleClicked ( const QModelIndex & index ) [signal]啦。

void QAbstractItemView::doubleClicked ( const QModelIndex & index ) [signal]
This signal is emitted when a mouse button is double-clicked. The item the mouse was double-clicked on is specified by index. The signal is only emitted when the index is valid.
