ToolTips for a Disabled control?

I have a wx.CheckBox in my program that I have associated a
wx.ToolTip with. I would dearly love for this Tooltip to be
displayed even if the checkbox is disabled.

(In fact I *especially* want the tooltip then, so the user can
hover over the disabled control and find out *why* it is
disabled.)

Unfortunately, wxPython does not show tooltips for disabled
controls, and EVT_ENTER_WINDOW events (which was my next idea)
are not generated either.

Does anybody know of a way to achieve what I want?

As ever, thanks in advance.
