override on grid feature

[smokeman]

I need to create an override on a feature of a grid. I can promote the grid to class, and create an override, but in this case, I really need to promote the grid feature to class, then create override...
is this possible, and how?

specifically, I need to override the onGroupClick: function of the Grouping feature, so I can disable the collapse/expand of the grouping header.
I'm adding 4.1.3 functionality to 4.0.7

in fact, how would you override anything, that you can't promote to class?

I have to get this done, and since there is no premium help for architect, I need someone from sencha to comment.

Even if I have to do this outside of architect...
If I do have to go outside of architect, it would be nice to have a pointer inside architect, so every timeI make edits in architect, I wouldn't have to go into eclipse, and fix the override.

Add an onGroupClick function to your grouping feature.

Start an Ext Project
Drag out a Grid
Add a grouping feature to the grid
Select the grouping feature in the inspector
Click the + to the right of "Functions" in the config grid
Click the drill down arrow ->
name the function onGroupClick
Give it the proper params: view, rowElement, groupName, e

Give it the implementation you want.

that is awesome!!!
I had no idea you could override built in functions that way....is this new?
That tells me I may have overrides in places, where this would have worked...

I get the nice little blue exclamation telling me it overrides parent function or config.

that was so eaasy, just the way I like it!
thanks aaron!

Been around for quite some time

we need a tips and tricks section for architect :-)
although, I would have looked at it when getting started, and been ignorant, as it is updated.
