Dear Voters;
I need an easy way to prevent the Windows font resource
from being released after setting the TFont->Handle property?

TFont takes ownership of the font resource. The previous resource assigned
to the Handle is automatically released when assigning a new resource to the
Handle, and the current Handle is automatically freed when the TFont itself
is freed.

I see. Thanks.
Related to that: is there a way to tell if hFont is a valid HFONT handle?
Like an API call IsWindow(HWND). Boba

The only thing I know of is to call GetObject() to get the font's LOGFONT
structure and check if GetObject() fails.
