Allow empty values for inline edit box

[[email protected]…]

Currently, the inlineEditBox widget does not allow for empty values. Most of the time, this is desired, but sometimes, it is not. I altered my copy of dojo to have a 'required' variable with a default of true. Then altered the 'saveEdit' and 'checkForValueChange' functions accordingly. That way I can set it to false when i want to allow empty values.

You can see my edits here: ​http://infinitysphere.no-ip.org/wsvn/foobar/trunk/dojo_svn_20070124/src/widget/InlineEditBox.js?op=file&rev=2&sc=0

Also, it would be nice if it checked the return value on the onSave handler. This would allow people to validate the new value.

I made the changes to cancel the save if onSave returns false:

On the webpage, instead of "event.connect(inlineEditBoxNode,'onSave',saveFunc)" I had to overwrite the onSave function with "inlineEditBoxNode.onSave = saveFunc"

The InlineEditBox? widget was rewritten for 0.9. Empty values are allowed now. An ampty value is displayed as a single ? so that it can be clicked and edited. All widgets that inherit from Textbox can be used as the editing widget and they all support the required attribute. Ths change will not be backported to 0.4.x.
