Drag select of columns in grid

[LarssaAndin]

I would really like to be able to drag select grid columns (like you can do with cells if you use the correct selection model).

Can someone give me an idea on how to add this feature to my grid? In cells there are mouse events to listen to but I can't figure out how to get that from the column headers.

I don't see that this exists with the SpreadsheetModel as far as column header selection goes, but take a look at this example to see if it gets you started toward a solution. It's a little rough around the edges, but should help.

Many thanks for this! I did have to rewrite it a bit, but that was because I'm including this feature inside my own version of the spreadsheet model and not by having it in the grid controller.

One thing that I recommend anyone using this code is to place the mouseup listener on the body (or perhaps the grid) as you now risk loosing the mouse up event if you happen to be outside the header when releasing the mouse button.

Another thing I will have to do some work with is that I have columns with subcolumns in my grids. The issue with this is that the sub column headers are located inside the box of the parent header. Not exactly difficult to solve, but still some work to make right.

If you don't mind sharing your finished solution, I'd be happy to see what you come up with. I can see this being a helpful feature.
