Incomplete doc for widgets API

[Amerio.Stephane]

Hello,

In the Widget API, what are exactly the arguments passed to these callbacks:

https://developer.unigine.com/en/docs/2.11/api/library/gui/class.widget?rlang=cpp#addCallback_int_Callback3_void_ptr

I couldn't figure out the second WidgetPtr and the int value passed.

Bonus question: in a radio button group, is it possible to know which radio is checked, without having to explicitly look at each one?

Thanks!

pointer - is used for Drag&drop operations. For details see Widgets/spritre_03 in  SDK UnigineScript samples.

data - is used for getting of mouse or keyboard button state, when widget is pressed or clicked (callbacks names: Gui::CLICKED, Gui::PRESSED, Gui::KEY_PRESSED)

There aren't embedded ways to do it. But you can set one callback (from Gui::CHANGED) for all widgets in group.
