Cancel CellList selection

Hello, Is there a way to cancel a user selection of a row in a "CellList" ? I can't find something like a "BeforeSelectionHandler" on a "TabLayoutPanel". I would like to be able to prompt a message indicating that the current edited object of the CellList has not been saved if the user clicks on a

I was looking something similar and your example is perfect. I am going with approach of having my custom SingleSelectionHandler i.e PromptingSelectionModel . My view is more like GWT Showcase CellList-DetailForm example. If I click on my cell, my code populates the form elements. My Form is a

Apologies Thomas, "onCellPreview" is actually called ! I didn't find yet which native event I should cancel, but I'm working on it... -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group. To post to this group, send email to google-web-toolkit@g

Re: Cancel CellList selection

It's not about cancelling the event; it's about *not* routing it to a DefaultSelectionEventManager (which changes selection depending on the event). It also means you shouldn't addCellPreviewHandler, but instead use the two-argument overload of setSelectionModel
