How to know if any of the widgets's values on current window has changed?

How-to

Hi,

I would like to have an “Apply” button that shows up whenever there is a change on any of current window(“Panel”)'s widgets.
The hard way to do this would be to define a call function for every single widget. But I was wondering if there is a more efficient way to do this.

Thanks

perhaps an LV_EVENT_VALUE_CHANGED will help you
