Re: CellTable and CeckboxCell
I got the multiple selection to work as I and Jocke want by adding a ButtonCell adjacent to the CheckboxCell. The code is in Bike Shed. The ButtonCell is also bound to the Selection Model. This takes care of what seem to be two bugs: 1) the CheckboxCell is not firing a setFieldUpdater event 2) the ButtonCell event is not fired correctly. Giving the table something else to do, i.e., with the CheckboxCell, helps the event to propagate correctly. For the record I also use the Selection Model's selection change listener to inform the presenter that a selection has changed.

It seems like there's a bug in CheckboxCell, which reverts the meaning of its constructor flag (from what I understand from reading the source code, note that I haven't done any test to confirm these observations): - CheckBoxCell(true) will actually make the cell a simple checkbox, while - CheckboxCell(false) will actually make it act like a select box And CheckboxCell() defers to CheckboxCell(false) I also think it should listen to click events rather than change events, as I'm not sure every browser fires change events (CheckBox uses click, not change); but that's another story. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: CellTable and CeckboxCell
That's correct I don't want the click to update the selectionModel. Creating the Cell like new CheckboxCell(true); makes the SelectionModel to get no events at all. On the other hand if I pass in false all events gets pass. I guess I will have to use the Event.NativePreviewHandler Regards Jocke 2010/8/27 Thomas Broyer t.bro...@gmail.com On 27 août, 10:45, jocke eriksson jock...@gmail.com wrote: I having trouble with a CheckboxCell, the problem is that if a user clicks on the checkbox the event bubbles up to the row element.

I mean, if you have editable cells, you should use a NoSelectionModel *or* have a column of CheckboxCell used to select/unselect lines. I suspect you'll have the exact same problem with any AbstractEditableCell, or ButtonCell, ActionCell or ClickableTextCell. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
