Qt - QTableView - 表行中的可点击按钮 [英] Qt - QTableView - Clickable button in table row

问题描述

我需要在 QTableView 的表行中有一个按钮/链接。这是打开一个对话框，允许更有效地编辑该行。

I require the ability to have a button/link within a table row of a QTableView. This is to open a dialog to allow that row to be edited more efficiently.

在网上查找后，我还没有找到一个体面的例子。

After hours of looking on the web I am yet to find a decent example.

我知道这可能是使用 QItemDelegate ，但我不确定如何有一个功能的小部件

I am aware that this is likely to be done using a QItemDelegate, but I am unsure how to have a functional widget within the row without forcing the item into edit mode first.

任何帮助都将非常感激。

Any help would be greatly appreciated.

推荐答案

您可以通过在可点击文本下划线来模拟链接的功能，然后通过cellClicked（row，col）信号捕获单元格点击并检查col == editColumn。

You could emulate the functionality of a link by underlining the clickable text, then capturing the cell click via the cellClicked(row, col) signal and check that col == editColumn. Then row would correspond to which item you are editing.

例如，

数据名称|值1 |值2 |

Data Name | Value 1 | Value 2 | Edit

connect (tableWidget, SIGNAL(cellClicked(int,int)), this, SLOT(editSlot(int, int)));

...

void ClassName::editSlot(int row, int col){
  if (col == 3) {
    doWork(row);
  }
}
