extracting the column content

[karansardana]

I would like the column not to get sorted if it contains the same data throughout, but I would certainly like the header to get highlighted in case of a click.

I was thinking of suppressing the event in case of equivalent column data, and still applying the style to the column's header.

Any suggestions on this/ is there any other/better way of doing this?

Thanks,Karan

your ide is good.


an other possible idea:

you can listen to the event: BeforeSort

it comes from ListStore:

  public void sort(String field, SortDir sortDir) {
    if (!fireEvent(BeforeSort, createStoreEvent())) {
      return;
    } 

in the attached store event you can access the store and look if the values are equal and then you can cancel the event.

but i see one problem there:

in the event you dont have the column for sorting :-( and not the sort direction. this makes this event useless :-( i

@sven: make it sense to add this to the event?


other solution: subclass the ListStore and check this in a overwritten sort() before calling the super.sort()


maybe there are other solutions for this.
