QTableView Multiple Editing Cell

epalmero

Dear All:

I am trying to create a QTableView where I use a Costumer model and all that is working perfect. Nonetheless I have an small problem. I would like to be able to edit multiple cell at the same time. This mean that if for example I have a Table of 3 x 3 and I select two elements of column 2 and I change one of this values then I change all of the selected one.

I think I have a way to do this by listen the dataChanged slot but I have a problem here. As soon as I have double click one of the cell to be able to change it I loose the selection. So the question is how I can do to be able to double click in a cell without loosing the selections?

All the best

Hi,

I'd suggest that you keep the selected cells by reimplementing selectionChanged() and using selectedIndexes() so that you know which cells to update when the users edits one of them.

The problem, I guess, would be distinguishing between the multiple-cell select the user makes, and the single-cell select that is made when you double-click.

Hi Andre:

Thanks is exactly my problem how I can make the difference between the single click and the double click. It look like that when I double click Qt call the single click in any case and thus why the selection is gone. Any suggestions?

The only thing I can think of, is using the time difference between the select action and the double click to determine if it a real selection or the start of an exit action. If the selection is followed by an edit action in the timespace of the double-click interval, I think you should revert to the selection you had before the sequence started.

Thanks very much I will try that one it sound as a good idea.
