+management</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>Many factors have to be taken into consideration when laying out controls.
+Component controls are normally laid out within their containers according
+to the prevailing UI policy, skin, font, text style, zoom-factor and the sizes
+and shapes of the controls themselves. A change to any one of these might
+necessitate a new layout. </p>
+<p>The Control Framework supports run-time layout management with the <xref href="GUID-A622B8C7-60F4-38E8-B102-14883BCBA249.dita"><apiname>MCoeLayoutManager</apiname></xref> interface.
+Each compound control knows which layout manager to call when it changes size.
+The layout manager then takes responsibility for making any adjustments to
+the layout. </p>
+<p>A layout manager is associated with a compound control using: </p>
+<codeblock id="GUID-B2CAA11F-EAEF-5583-A86D-BEF8A279EF22" xml:space="preserve"> IMPORT_C virtual void SetLayoutManagerL(MCoeLayoutManager* aLayout);</codeblock>
+<p>Note that this call passes 'ownership' so the caller does not need to retain
+a pointer. A layout manager may be attached to more than one control so it
+must implement its own reference count and delete itself when the count becomes
+zero. <codeph>SetLayoutManagerL()</codeph> is also used to dissociate a layout
+manager from a control by passing either NULL or a pointer to a different
+layout manager. </p>
+<p>The Control Framework does not provide any concrete layout managers. This
+is the responsibility of the UI variant library or the application developer. </p>
+<p>Though layout managers are now built into the control framework their use
+is optional. </p>
