#2817 Directly edit fwt Table and Disable Column Sorting

small_petit Mon 14 Dec 2020

Hello, please I want to know if it is possible to edit Fantom FWT Table cells directly. As in double-clicking and entering new cell values.

Also, can I please know how to disable the sorting behaviour on column header clicks?

Thank you.

Well, I could only let a dialog open, so I can enter the new value. Here is the code:

table.onMouseDown.add |Event e| 
        if (e.count == 2)
            row := table.rowAt(e.pos)
            col := table.colAt(e.pos)
            ans := Dialog.openPromptStr(e.window, "Enter new value:")
            model.data[row][col] = ans.toInt

But I really wish I could just edit the values directly as in spreadsheet programs where you double-click, and do your edit right away.

I am still working out how to turn the automatic column sorting behaviour off.

Thank you.

Hey small_petit, I missed this yesterday!

As you've surmised, there is no table edit feature in fwt - I'm afraid it's just not that advanced. Your prompt popup on click is the best way.

I don't think there's an inbuilt way to disable sorting either. The best I can think of is overriding TableModel.sortCompare() to always return the same desired ordering. That way, when the table is sorted, the order doesn't change.

Thanks SlimerDude.

In my Table model class, I did:

override Int sortCompare(Int col, Int row1, Int row2)
    return 0

And sure, my table maintains the sort order of the way I inserted values.

Thank you once again for your help.
