<P>In this section we have introduced some of the graphics capabilities 
of
<font size=-1>XPCE</font>. <font size=-1>XPCE</font>'s graphics are 
built from primitive and compound graphicals. A compound graphical has 
its own coordinate system in which it can display any graphical object 
including other compound objects. Graphical objects can be connected to 
each others using a <A class="" href="summary.html#class:connection">connection</A>. 
This facility makes the generation of graphs relatively simple. It also 
makes it very simple to extract the graph represented by a drawing made 
by the user.

<P>Graphical objects are made sensitive to mouse and keyboard activities 
by attaching <A class="" href="summary.html#class:recogniser">recogniser</A> 
objects to them. <font size=-1>XPCE</font> defines standard recognisers 
for various complex operations such as moving, resizing, popup-menu's, 
linking graphicals and clicking on graphicals.
