<A NAME="sec:controller"></A>
<P><A NAME="idx:controllers:115"></A><font size=-1>XPCE</font> Dialog
windows are normally used to display a number of controllers, named <A class="" href="summary.html#class:dialog_item">dialog_item</A><EM>s</EM>
in <font size=-1>XPCE</font>'s jargon. Class
<A class="" href="summary.html#class:dialog">dialog</A> is a subclass of <A class="" href="summary.html#class:window">window</A>
with specialised methods for positioning controllers. Dialog items are
graphical objects specialised for displaying and/or editing particular
data.
<A class="fig" href="controller.html#fig:dialoghierarchy">Figure 7</A>
illustrates the inheritance relations relevant to dialog windows and the
locations of the most important methods.

<P>Dialogs can be created both by using the <A NAME="idx:new2:116"></A><A class="pred" href="sec-D.1.html#new/2">new/2</A>
and <A NAME="idx:send212:117"></A><A class="pred" href="sec-7.1.html#send/[2-12]">send/[2-12]</A>
operations as well as by using the Dialog Editor which is described in
<A class="sec" href="dialogeditor.html">appendix A</A>. This section
describes the first mechanism. Reading this chapter will help you
understanding the dialog editor.
