[ gpsdrive ] Embedded GpsDrive using GTK Plug (XEMBED)

[Jim Gruen]

Hello folks,
	After a cursory search of the mailing list archives, I could not find  
a similar patch to this.  So I have attached a very small diff to the  
GpsDrive trunk that enables "embedded" mode using a new command-line  
parameter, '-m'.  This will cause GpsDrive to use a GTK "Plug" instead  
of a "Window," then print out the window's ID to standard output.   
Meanwhile, the GUI will not appear until a GTK "Socket" in a separate  
application uses that same ID to embed and show the GpsDrive GUI.  Why  
do this?  Because I am using this to embed GpsDrive into a PyGTK CarPC  
application.  For a small example of using a GTK Socket from Python,  
look here*:
http://www.pygtk.org/pygtk2tutorial/sec-PlugsAndSockets.html
	Note that I am not sure if this will compile on Win32, as that  
platform may not have Plug/Socket support from GTK (to remedy this,  
some #ifdefs could be added around the relevant GTK Plug code in  
main_gui.c).
	Comments are welcome!

Cheers,
-Jim

(*)  Note also that the socket.py example on the referenced website  
expects a decimal window ID on the command line, instead of the normal  
hex.  To fix this, add ', 16' (the number 16 as a second parameter) to  
the call to long(argv[1]).
