<h2>Detailed Description</h2>
<p>The QDeclarativeItem class provides the most basic of all visual items in QML.</p>
<p>All visual items in Qt Declarative inherit from QDeclarativeItem. Although QDeclarativeItem has no visual appearance, it defines all the properties that are common across visual items - such as the x and y position, the width and height, <a href="qml-anchor-layout.html#anchor-layout">anchoring</a> and key handling.</p>
<p>You can subclass QDeclarativeItem to provide your own custom visual item that inherits these features. Note that, because it does not draw anything, QDeclarativeItem sets the <a href="qgraphicsitem.html#GraphicsItemFlag-enum">QGraphicsItem::ItemHasNoContents</a> flag. If you subclass QDeclarativeItem to create a visual item, you will need to unset this flag.</p>

<p>This property holds the position of the item's baseline in local coordinates.</p>
<p>The baseline of a <a href="qml-text.html">Text</a> item is the imaginary line on which the text sits. Controls containing text usually set their baseline to the baseline of their text.</p>
<p>For non-text items, a default baseline offset of 0 is used.</p>

<p>If clipping is enabled, an item will clip its own painting, as well as the painting of its children, to its bounding rectangle. If you set clipping during an item's paint operation, remember to re-set it to prevent clipping the rest of your scene.</p>

<h3 class="fn"><a name="childAt"></a><span class="type">QDeclarativeItem</span> * QDeclarativeItem::<span class="name">childAt</span> ( <span class="type"><a href="qtglobal.html#qreal-typedef">qreal</a></span> <i>x</i>, <span class="type"><a href="qtglobal.html#qreal-typedef">qreal</a></span> <i>y</i> ) const</h3>

<p>Maps the point (<i>x</i>, <i>y</i>), which is in <i>item</i>'s coordinate system, to this item's coordinate system, and returns a script value with <tt>x</tt> and <tt>y</tt> properties matching the mapped cooordinate.</p>
<p>If <i>item</i> is a <tt>null</tt> value, this maps the point from the coordinate system of the root QML view.</p>

<!-- $$$setImplicitHeight[overload1]$$$setImplicitHeightqreal -->
<h3 class="fn"><a name="setImplicitHeight"></a><span class="type">void</span> QDeclarativeItem::<span class="name">setImplicitHeight</span> ( <span class="type"><a href="qtglobal.html#qreal-typedef">qreal</a></span> <i>h</i> )<tt> [protected]</tt></h3>
<p>Sets the implied height of the item to <i>h</i>. This is the height implied by other properties that determine the content.</p>
<p><b>See also </b><a href="qdeclarativeitem.html#implicitHeight-prop">implicitHeight</a>().</p>
<!-- @@@setImplicitHeight -->
<!-- $$$setImplicitWidth[overload1]$$$setImplicitWidthqreal -->

<!-- @@@setImplicitWidth -->
<!-- $$$setKeepMouseGrab[overload1]$$$setKeepMouseGrabbool -->
<h3 class="fn"><a name="setKeepMouseGrab"></a><span class="type">void</span> QDeclarativeItem::<span class="name">setKeepMouseGrab</span> ( <span class="type">bool</span> <i>keep</i> )</h3>
<p>The flag indicating whether the mouse should remain with this item is set to <i>keep</i>.</p>
<p>This is useful for items that wish to grab and keep mouse interaction following a predefined gesture. For example, an item that is interested in horizontal mouse movement may set keepMouseGrab to true once a threshold has been exceeded. Once keepMouseGrab has been set to true, filtering items will not react to mouse events.</p>
<p>If the item does not indicate that it wishes to retain mouse grab, a filtering item may steal the grab. For example, Flickable may attempt to steal a mouse grab if it detects that the user has begun to move the viewport.</p>
