Re: GWT 2.4 - problems with space key handling and FieldUpdater for TextInputCell inside CompositeCell in CellTree

The issue is due to CellTree preventing the default browser event on space. The reason for that is to prevent scrolling.

 

You can listen for KEYDOWN in TextInputCells  and then add the space in the input manually. As to how to get the input element, you can traverse the DOM from the parent Element or use something like GQuery.

I am facing the same issue and cannot figure out how the original poster set up event handling to get this working.  Any help would be greatly appreciated.  Right now my CellTree with TextInputCells will not accepts spaces.

Hi James,

Thanks for the post and reply.

I am facing similar issue. I am not able to type the white space character in the MyEditCell extends AbstractInputCell.

i have also over ridden the below method:

public Set<String> getConsumedEvents() {

Set<String> events = new HashSet<String>();

events.add("focus");

events.add("blur");

events.add("keydown");

events.add("change");

return events;

}

But, Still no luck.

Can you please suggest something.

 

Thanks,

Bhasker

Looks like it boils down to events. After looking at the TextInputCell
and AbstractInputCell source, I added "focus" and "change" events to
the list of events consumed by the CompositeCell, and that addressed
both issues.

Incidentally, I tried out the EditTextCell in the CompositeCell, and
to get that working, I needed to add "keyup" and "keydown" events to
the CompositeCell.

Clearly I do not yet have my mind wrapped around how the events are
propagated in a CompositeCell, but at least I've solved my immediate
problems.
