It does work with the wx HEAD that I checked out a couple days ago.

I wanted to understand this better, so I did some searching.
At least for msw, I found two techniques that are claimed to work:

http://www.codeguru.com/cpp/controls/controls/tooltipcontrols/article.php/c2277/
|      The hwnd of the WM_MOUSEMOVE above a disabled control

|
|      To correct this, if we get WM_MOUSEMOVE and the hwnd is the
|      dialog's hwnd
|
|      We check on all the controls that are Visible, but disabled
|      if the point is in their rectangle.

| In this case we alter the msg to the controls hWnd and coordinates before

[Send TTM_WINDOWFROMPOINT to get the window under the point, even
if it's a disabled control; change LPARAM to that window to make
the tooltip show that window's text.]

Do you find those ideas interesting for wx-msw?

Does gtk already show tooltips for disabled controls?
