See http://code.google.com/p/google-web-toolkit/issues/detail?id=5641 (for now, you'd have to use your own ButtonCell if you want the fixed behavior) > Inspecting the code for this example and the sample from CellList i > see the following: > > From the CellList example, each cell is a div with a single onclick. > > <div onclick="" __idx="0" class="GEGGSC0BI" > style="outline:none;"><table><tbody><tr> ... </tr></tbody></table></ > div> > > From the CellSampler (which uses a cellTable) the onclick is not in > each cell but in each row. > <tr onclick="" class="GEGGSC0BED"><td class="GEGGSC0BDC GEGGSC0BFD > GEGGSC0BGC"><div style="outline:none;"></div></td></tr> > > I tried to use a composite cell with two buttons in a celllist but as > there is only one handler per cell, clicking on any of the two buttons > (and also outside the buttons but inside the cell) reacts with the > same handler.

If you want columns though, you have to use CellTable, of make your own Cell widget (not trivial) > Question 4 How do you managed to distinguish cellclicks if there is > only one handler per row in a celltable? > Cell widgets use "event delegation", they register a single event listener but then dispatch accordingly, depending on the exact element targetted by the event (i.e. FieldUpdater for a given Column, onBrowserEvent and ValueUpdater for a given Cell) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
