The tooltip docs say that

A tooltip control always has the WS_POPUP and WS_EX_TOOLWINDOW window styles, regardless of whether you specify them when creating the control.

Meanwhile, the way to custom draw a tooltip is through WM_NOTIFY/NM_CUSTOMDRAW, which would require a parent.

So how is custom-draw performed if the tooltip is always a popup?

Notification messages are sent to the window specified in the `TTTOOLINFO` structure when you add the tool to the tooltip. – Jonathan Potter Oct 25 '21 at 05:01
