<code>type TUIContainer = class abstract(TComponent)</code></p>
<h2 class="description">Description</h2>
<p>
Abstract user interface container. Connects OpenGL context management code with Castle Game Engine controls (<a class="normal" href="CastleUIControls.TUIControl.html">TUIControl</a>, that is the basis for all our 2D and 3D rendering). When you use <a class="normal" href="CastleWindow.TCastleWindowCustom.html">TCastleWindowCustom</a> (a window) or <a class="normal" href="CastleControl.TCastleControlCustom.html">TCastleControlCustom</a> (Lazarus component), they provide you a non-abstact implementation of <code>TUIContainer</code>.
<p>Basically, this class manages a <a class="normal" href="CastleUIControls.TUIContainer.html#Controls">Controls</a> list.
<p>We pass our inputs (mouse / key events) to these controls. Input goes to the top-most (that is, first on the <a class="normal" href="CastleUIControls.TUIContainer.html#Controls">Controls</a> list) control under the current mouse position (we check control's PositionInside method for this). As long as the event is not handled, we look for next controls under the mouse position.
<p>We also call other methods on every control, like TUIControl.Update, <a class="normal" href="CastleUIControls.TUIControl.html#Render">TUIControl.Render</a>.</p>

Force passing events to given control first, regardless if this control is under mouse cursor. This control also always has <a class="normal" href="CastleUIControls.TUIContainer.html#Focus">focus</a>.
<p>An example when this is useful is when you use camera MouseLook, and the associated viewport does not fill the full window (<a class="normal" href="CastleSceneManager.TCastleAbstractViewport.html#FullSize">TCastleAbstractViewport.FullSize</a> is <code>False</code>, and actual sizes are smaller than window, and may not include window center). In this case you want to make sure that motion events get passed to this control, and that this control has <a class="normal" href="CastleUIControls.TUIContainer.html#Focus">focus</a> (to keep mouse cursor hidden).
<p>This is used only if it is also present on our <a class="normal" href="CastleUIControls.TUIContainer.html#Controls">Controls</a> list, as it doesn't make sense otherwise. We also cannot reliably track it's existence when it's outside our <a class="normal" href="CastleUIControls.TUIContainer.html#Controls">Controls</a> list (and we don't want to eagerly <code>Nil</code> this property automatically).</p>
