[SOLVED] No notification of listicongadget header click, if it's inside PanelGadget

[Caronte3D]

Until now I have used this code to sort the ListIconGadget lines clicking on her header, works nice, but my ListIconGadget is inside a PanelGadget and now not work anymore, Don't know since what version, but not work with the PB 6.02 beta 2-3.
To test it, un comment the 3 lines indicated afterOpenWindow.

EDIT: With the PB 6.01 LTS works nice (as expected).

WM_NOTIFY is sent to the parent window, not to the root window. It was 'luckily' working before, but the bug has been fixed so you need to attach your callback to the panelgadget item (it also works properly on 64-bit):

Ok, but...
If I have several Panels I can repeat your example for everyone?
Also, until now I have a WindowCallback to process another things related to the main window, so I can use it too?
As you can notice, I don't understand to much about callbacks

EDIT: I answer my self Yes, I can keep my WindowCallback for other tasks.

@Caronte3D: Maybe GetActiveGadget()?

[Caronte3D]

I think no, but i will take a look
