I only know a bad way to do this, so I'd like someone else to show me a better way to do this.
As with most GWT Cells, as soon as I want to do something different, I have to create my own. So I suggest you look up the code for EditTextCell, copy and paste it into a new MyEditTextCell and then change the commit() method to do what you want. In my case, I needed EditTextCell to use a textarea instead of a textbox, so I had already copied and pasted the code out to make it use a textarea. When the requirement came down that I needed to give people a confirm when they changed the text (sigh), I modified the commit method similar to: private void commit(final Context context, final Element parent, final ViewData viewData, final ValueUpdater<String> valueUpdater) { if(Window.confirm("Really update value?")) { String value = updateViewData(parent, viewData, false); clearInput(getInputElement(parent)); setValue(context, parent, viewData.getOriginal()); if (valueUpdater != null) { valueUpdater.update(value); } } } I'd be happy if someone could point out a way to do things like this in a way that allows me to not have to copy/paste GWT Cell code into my own project.
