	I've been typing in some more of the sample progrmams from the book
that I recently got, and my question is this:  I'm using the function
GpiCharStringAt, and just for the hell of it, I brought up the "Font
Palette" and dragged a different font to my window to see what would
happen.  There was no visible change, but if I then "invalidated" some
portion of the window, that portion, when refreshed, came back in the
new font.  My question is:  What message is sent to my window procedure
when I drag a new font to the window?  I tried a couple of the more
obvious ones, I don't remember their names right now, something about
SYSVALUE and COLORCHANGE, I'm not sure.  Also, I'm assuming that this is
the way these features work, if they're not, let me know what the
standard way of dealing with them is.  I've also tried dragging a new
color to the window, and it seems to make no difference at all.  Is
there a message that also goes with a color change?  Some pseudo-code
would also be helpful.  Thanks.

Did you look at WM_SETWINDOWPARAMS?  The WNDPARAMS structure contains
Presentation Parameter length and data pointer elements.

The window gets a WM_PRESPARAMCHANGED message.
You can get the new presentation parameter (font, colour, etc) by
an appropriate call to WinQueryPresParam.
