Detect widget changed

[malc_b]

Hi,

Sorry this is in English

How do I detect when a widget has changed?  I want to change the color of the select background.  I can do

Code Auswählen Erweitern

$("#myselect > select").on("change", function().......

but that only works when I change the value on screen.  If it changes via a timer say then the state is update but the onchange is no triggered.  I did try

Code Auswählen Erweitern

$(document).on("updateDone", function()......

but that doesn't seem to run for me.  Or at least not at each update.

I did think about using class changer widget but I could not think of way of taking the class down to select background.

[setstate]

As far as I know, I would say, the widget has to emit such a change by its own.
The Select Widget must be extended
Add elem.trigger('changedItem'); into setCurrentItem function.

And then you could subscribe this new event.
