|
<p> We have kept the main() function simple and small. We create a
|
|
<a href="tqapplication.html">TQApplication</a> object and pass it the command line arguments. We are
|
|
allowing users to invoke the program with <tt>chart mychart.cht</tt>, so if
|
|
they've added a filename we pass that through to the chart form
|
|
constructor. Most of the action takes place within the chart form
|
|
which we'll review next.
