<h1 style="margin-top:0px">hgeGUIObject helper class</h1>
<p>
<b>hgeGUIObject</b> is an abstract class used to define custom GUI controls.
The default classes <a href="hgegui_guitext.html">hgeGUIText</a>,
<a href="hgegui_guibutton.html">hgeGUIButton</a> and <a href="hgegui_guislider.html">hgeGUISlider</a>
are derived from it. You can create your own controls deriving their classes from <b>hgeGUIObject</b>.
<br><br>
All the methods of <b>hgeGUIObject</b> are <b>virtual</b>. If you don't need some of the methods, you could just use defaults and not redefine them.
The only methods you must define in a derived class are <a href="hgeguio_constructor.html">Constuctor</a> and <a href="hgeguio_render.html">Render</a>.
You could also use virtual destructor.
