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 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.
