<p> 
<p> The <tt>chart</tt> application shows how straight-forward it is to create
applications and their dialogs with TQt. Creating menus and toolbars is
easy and TQt's <a href="signalsandslots.html">signals and slots</a>
mechanism considerably simplifies GUI event handling.
<p> Manually creating layouts can take some time to master, but there is
an easy alternative: <a href="designer-manual.html">TQt&nbsp;Designer</a>.
<a href="designer-manual.html">TQt&nbsp;Designer</a> includes simple but
powerful layout tools and a code editor. It can automatically generate
<tt>main.cpp</tt> and the <tt>.pro</tt> project file.
<p> The <tt>chart</tt> application is ripe for further development and
experimentation. You might consider implementing some of the following
ideas:
<ul>
<li> Use a <a href="qvalidator.html">TQValidator</a> subclass to ensure that only valid doubles are
entered as values.
<li> Adding more chart types, e.g. line graph, area graph and hi-lo
graph.
<li> Allowing the user to set top, bottom left and right margins.
<li> Allowing the user to specify a title which they can drag into
position like the labels.
<li> Providing an axis drawing and labelling option.
<li> Providing an option to provide a key (or legend) instead of labels.
<li> Adding a 3D look option to all chart types.
</ul>
