Re: Celltable w/ selectionModel and ActionCells
r9788 adds a new BlacklistEventTranslator and WhitelistEventTranslator for
use in DefaultSelectionEventManager. Using these, you can disable/enable
selection for specific columns.
http://code.google.com/p/google-web-toolkit/source/detail?r=9788
DefaultSelectionEventManager manager =
DefaultSelectionEventManager.createBlacklistManager(0,
3); // Ignore clicks on columns 0 and 3
SelectionModel model = new SingleSelectionModel();
cellTable.setSelectionModel(model, manager);
Hope this helps with this issue. You can wait for GWT 2.3, or just copy the
BlacklistEventTranslator code into your app and call
DefaultSelectionEventManager.createCustomManager(myBlacklistEventTranslator).

Re: Celltable w/ selectionModel and ActionCells
You can try overriding ActionCell#handlesSelection() to return true to
disable the default selection. We might need to do so for all interactive
cells and change the JavaDoc of Cell#handlesSelection() to clarify that it
can be used to simply disable default selection. But in general, this is
what handlesSelection() was designed to do.

Re: Celltable w/ selectionModel and ActionCells
ActionCell already returns false for handlesSelection(). If a cell
declares to handle the selection, the default way of (de)selecting, by
clicking in the row, does not work anymore. Then it is the value-
updater's task to do so. I recently wrote something about it in a blog
post. See for more information:

Re: Celltable w/ selectionModel and ActionCells
I haven't played with this a whole bunch but have you looked at
handlesSelection? I was under the impression that by setting this to
false you indicate that a particular cell type is not allowed to
determine selection state?
Like if you have a checkboxcell it can be the only cell that
determines whether or not the row is selected.

Re: Celltable w/ selectionModel and ActionCells
This is not possible. In your case, the click event is always also
given to the SelectionModel.
See line 971 in CellTable (http://www.google.com/codesearch/p?
hl=en#A1edwVHBClQ/user/src/com/google/gwt/user/cellview/client/
CellTable.java&q=CellTable%20package:http://google-web-toolkit
%5C.googlecode%5C.com&sa=N&cd=1&ct=rc):
if (selectionModel != null && "click".equals(eventType) && !
handlesSelection) {
selectionModel.setSelected(value, true);
}
As you can see, if you could make the handlesSelection boolean true,
the selectionModel will not be updated. This boolean is true if one
(or more) cell(s) declare(s) to handle the selection. ActionCell does
not do that. What you can do is create your own cell, make it handle
the selection, and use it for all the columns that you want to be
clickable.

Celltable w/ selectionModel and ActionCells
hi, i have a celltable with a selectionModel but also a column of actioncells. the selectionModel and actioncells both handle click events, but when i click the action cell, it also triggers the selectionmodel click handler. is it possible to prevent this? Or do i have to nix the selectionModel and go with clickable cells on the row? thanks. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
