SKINNING - ways to pass a value (text) to a skinning callback

Dear all

How can I pass a text to a common skinning callback without having to check what widget it has been?
I would like to do it without using:
- globals
- WM_GetId();
- <WIDGET>_GetUserData to get, for example, the index

Thanks very much for support so far

There is no way to pass a string directly to a skinning routine. You can set a string to most widgets are receive this string by calling the GetText function of this widget.

For example, set a string to a button with BUTTON_SetText() and receive it inside the skinning function with a call of BUTTON_GetText(). You can use the handle which is past to the skinning routine in the WIDGET_ITEM_DRAW_INFO structure, pDrawItemInfo->hWin. This is always the widget this skinning function belongs to.
