<div class="descr"> <a name="details"></a>
<p>a value with width and height attributes</p>
<p>The <code>size</code> type refers to a value with has <code>width</code> and <code>height</code> attributes.</p>
<p>For example, to read the <code>width</code> and <code>height</code> values of the Image::sourceSize size-type property:</p>
<pre class="qml">
<span class="type">Column</span> {
<span class="type">Image</span> { <span class="name">id</span>: <span class="name">image</span>; <span class="name">source</span>: <span class="string">"logo.png"</span> }
<span class="type">Text</span> { <span class="name">text</span>: <span class="name">image</span>.<span class="name">sourceSize</span>.<span class="name">width</span> <span class="operator">+</span> <span class="string">","</span> <span class="operator">+</span> <span class="name">image</span>.<span class="name">sourceSize</span>.<span class="name">height</span> }
}
</pre>
<p>To create a <code>size</code> value, specify it as a "width x height" string:</p>
<pre class="qml">
<span class="type">Image</span> { <span class="name">sourceSize</span>: <span class="string">"150x50"</span> }
</pre>
<p>Or use the <a href="qml-qtqml-qt.html#size-method">Qt.size()</a> function:</p>
<pre class="qml">
<span class="type">Image</span> { <span class="name">sourceSize</span>: <span class="name">Qt</span>.<span class="name">size</span>(<span class="number">150</span>, <span class="number">50</span>) }
</pre>
<p>When integrating with C++, note that any QSize or QSizeF value <a href="qtqml-cppintegration-data.html">passed into QML from C++</a> is automatically converted into a <code>size</code> value, and vice-versa. When a <code>size</code> value is passed to C++, it is automatically converted into a QSizeF value.</p>
