Works, but I noticed another problem after that, when I edit a branch, after validating, it steps directly to the next branch (in edit mode) and not to the node (leaf in my case, see pictures below) just below.
You can disable the toggle by adding a beforedblclick event listener and returning false. Since the editing events are tied to the tree body and not the panel body, this will not affect editing or events associated with editing.
Wait for your answer thank you very much.
The editor is positioned at the top left of the cell. When I created this i didn't take into account form elements like checkboxes so it handles all them the same in terms of editor position. I'll need to add some code to check for form element type before positioning the editor. I'll put this into the next update.
Thank you, it was just for information, don't bother.
I don't know how a checkcolumn model could be added. Ext was a little misleading calling the TreeGrid a grid, when it is more like a TreeListView. The columns are borrowed from the ListView, which in turn is loosely borrowed from the Grid, however, with a ListView, and consequently with the TreeGrid, no column model is actually used, so i'm not sure how you could get that in there. I'll take a look at it when i can, i should be able to mimic that functionality.
