<h2 class="description">Description</h2>
<p>
OpenGL control, with extensions for "Castle Game Engine", including <a class="normal" href="CastleControl.TCastleControlCustom.html#Controls">Controls</a> list for <a class="normal" href="CastleUIControls.TUIControl.html">TUIControl</a> instances. Use a descendant <a class="normal" href="CastleControl.TCastleControl.html">TCastleControl</a> to have a ready <a class="normal" href="CastleControl.TCastleControl.html#SceneManager">TCastleControl.SceneManager</a> for 3D world.
<p>This extends TOpenGLControl, adding various features:
<p></p>
<ul class="paragraph_spacing">
<li><p><a class="normal" href="CastleControl.TCastleControlCustom.html#Controls">Controls</a> list where you can easily add <a class="normal" href="CastleUIControls.TUIControl.html">TUIControl</a> instances (like <a class="normal" href="CastleOnScreenMenu.TCastleOnScreenMenu.html">TCastleOnScreenMenu</a>, <a class="normal" href="CastleControls.TCastleButton.html">TCastleButton</a> and more). We will pass events to these controls, draw them etc.</p></li>
<li><p>Continously called <a class="normal" href="CastleControl.TCastleControlCustom.html#DoUpdate">DoUpdate</a> method, that allows to handle TUIControl.Update. This is something different than LCL "idle" event, as it's guaranteed to be run continously, even when your application is clogged with events (like when using <a class="normal" href="CastleCameras.TWalkCamera.html#MouseLook">TWalkCamera.MouseLook</a>).</p></li>
<li><p>Automatically calls <a class="normal" href="CastleGLUtils.html#GLInformationInitialize">GLInformationInitialize</a> when OpenGL context is initialized. This will initialize <a class="normal" href="CastleGLVersion.html#GLVersion">GLVersion</a>, <a class="normal" href="CastleGLVersion.html#GLUVersion">GLUVersion</a>, <a class="normal" href="CastleGLUtils.html#GLFeatures">GLFeatures</a>.</p></li>
<li><p>FPS (frames per second) counter inside <a class="normal" href="CastleControl.TCastleControlCustom.html#Fps">Fps</a>.</p></li>
<li><p>Tracks pressed keys <a class="normal" href="CastleControl.TCastleControlCustom.html#Pressed">Pressed</a> and mouse buttons <a class="normal" href="CastleControl.TCastleControlCustom.html#MousePressed">MousePressed</a> and mouse position <a class="normal" href="CastleControl.TCastleControlCustom.html#MousePosition">MousePosition</a>.</p></li>

Event called when the OpenGL context is created, you can initialize things that require OpenGL context now. Often you do not need to use this callback (engine components will automatically create/release OpenGL resource when necessary), but sometimes it may be handy (e.g. <a class="normal" href="CastleGLImages.TGLImage.html">TGLImage</a> requires OpenGL context). You usually will also want to implement <a class="normal" href="CastleControl.TCastleControlCustom.html#OnClose">OnClose</a> callback that releases stuff created here.
<p>Even when you really need to initialize some OpenGL resource (like <a class="normal" href="CastleGLImages.TGLImage.html">TGLImage</a>), instead of using this callback it's usually better to derive new classes from <a class="normal" href="CastleUIControls.TUIControl.html">TUIControl</a> class or it's descendants, and override their GLContextOpen / GLContextClose methods to react to context being open/closed. Using such <a class="normal" href="CastleUIControls.TUIControl.html">TUIControl</a> classes is usually easier, as you add/remove them from controls whenever you want (e.g. you add them in ApplicationInitialize), and underneath they create/release/create again the OpenGL resources when necessary.</p>

<p>Note that reporting characters for "key release" messages is not perfect, as various key combinations (sometimes more than one?) may lead to generating given character. We have some intelligent algorithm for this, used to make Characters table and to detect this C for <code>OnRelease</code> callback. The idea is that a character is released when the key that initially caused the press of this character is also released.
<p>This solves in a determined way problems like "what happens if I press Shift, then X, then release Shift, then release X". (will "X" be correctly released as pressed and then released? yes. will small "x" be reported as released at the end? no, as it was never pressed.)</p>
