+controls</title>
+<p>Window-owning controls have the same size and position as a window in
+the display. Each window has a one-to-one relationship with the control that
+covers it, and shares its behavior with that control.</p>
+<p>Examples of window-owning controls include:</p>
+<ul>
+<li><p>top-level control in <xref href="GUID-B5DE1C86-2B16-4B22-887F-7079E54A8ED6.dita">Traditional
+Symbian architecture</xref></p></li>
+<li><p>the subpanes in the status pane</p></li>
+<li><p>pop-up windows, when a sense of layering is required</p>
+</li>
+</ul>
+<p>The following code snippet is an example of the second phase construction
+of a window-owning control:</p>
+<codeblock id="GUID-234E4AC3-2FC8-4AD9-8B72-0FBA478E1D5A" xml:space="preserve">CMyControl::ConstructL()
+    {
+    CreateWindowL();    // This makes the control window- 
+                        // owning
+    SetRectL(ClientRect()); // This sets the control’s 
+                            // size
+    ActivateL();        // This must be called before
+                        // the control can be drawn
+    }
+</codeblock>
+<p><parmname>ClientRect()</parmname> returns the screen area available
+to the application for drawing. This typically does not include the space
+that is reserved for the status/control panes.</p>

+<section id="GUID-13D754E5-EBCF-4058-B3B3-05505289953B"><title>Non-window-owning
+controls</title>
+<p>Non-window-owning controls typically cover only part of a window on
+the display, and must be contained in window-owning controls. They are faster
+and require fewer resources than window-owning controls.</p>
+<p>Examples of non-window-owning controls include:</p>
+<ul>
+<li><p>command buttons</p></li>
+<li><p>edit windows</p></li>
+<li><p>labels</p></li>
+</ul>
+<p>Non-window-owning controls are assigned to window-owning controls by
+calling <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Control_Environment/CCoeControlClass.html#%3a%3aCCoeControl%3a%3aSetContainerWindowL%28RBackedUpWindow%20%26amp%3b%29" format="application/java-archive"><parmname>CCoeControl::SetContainerWindowL</parmname></xref> when the
+control is constructed.</p>
