<span class="subtitle"></span>
<!-- $$$qtquickcontrols2-customize.html-description -->
<div class="descr"> <a name="details"></a>
<p>Qt Quick Controls 2 consist of a hierarchy (tree) of items. In order to provide a custom look and feel, the default QML implementation of each item can be replaced with a custom one.</p>
<a name="customizing-a-control"></a>
<h2 id="customizing-a-control">Customizing a Control</h2>
<p>Sometimes you'll want to create a "one-off" look for a specific part of your UI, and use a complete style everywhere else. Perhaps you're happy with the style you're using, but there's a certain button that has some special significance.</p>
<p>The first way to create this button is to simply define it in-place, wherever it is needed. For example, perhaps you're not satisfied with the default style's Button having square corners. To make them rounded, you can override the <a href="qml-qtquick-controls2-control.html#background-prop">background</a> item and set the radius property of Rectangle:</p>
<pre class="qml">
import QtQuick 2.6
import QtQuick.Controls 2.0
<span class="type">ApplicationWindow</span> {
<span class="name">width</span>: <span class="number">400</span>
<span class="name">height</span>: <span class="number">400</span>
<span class="name">visible</span>: <span class="number">true</span>
<span class="type">Button</span> {
<span class="name">id</span>: <span class="name">button</span>
<span class="name">text</span>: <span class="string">"A Special Button"</span>
<span class="name">background</span>: <span class="name">Rectangle</span> {
<span class="name">implicitWidth</span>: <span class="number">100</span>
<span class="name">implicitHeight</span>: <span class="number">40</span>
<span class="name">color</span>: <span class="name">button</span>.<span class="name">down</span> ? <span class="string">"#d6d6d6"</span> : <span class="string">"#f6f6f6"</span>
<span class="name">border</span>.color: <span class="string">"#26282a"</span>
<span class="name">border</span>.width: <span class="number">1</span>
<span class="name">radius</span>: <span class="number">4</span>
}
}
}
</pre>
<p>The second way to create the button is good if you plan to use your rounded button in several places. It involves moving the code into its own QML file within your project.</p>
<p>For this approach, we'll copy the background code from the default style's <code>Button.qml</code>. This file can be found in the following path in your Qt installation:</p>
<p><code>$QTDIR/qml/QtQuick/Controls.2/Button.qml</code></p>
<p>After doing that, we'll simply add the following line:</p>
<pre class="cpp">
radius: <span class="number">4</span>
</pre>
<p>To avoid confusion with the controls in the module itself, we'll call the file <code>MyButton.qml</code>. To use the control in your application, refer to it by its filename:</p>
<pre class="qml">
import QtQuick.Controls 2.0
<span class="type">ApplicationWindow</span> {
<span class="type">MyButton</span> {
<span class="name">text</span>: <span class="name">qsTr</span>(<span class="string">"A Special Button"</span>)
}
}
</pre>
<p>The third way to create the button is a bit more structured, both in terms of where the file sits in the file system and how it is used in QML. First, copy an existing file as you did above, but this time, put it into a subfolder in your project named (for example) <code>controls</code>. To use the control, first import the folder into a namespace:</p>
<pre class="qml">
import QtQuick.Controls 2.0
import "controls" as MyControls
<span class="type">ApplicationWindow</span> {
<span class="type">MyControls</span>.Button {
<span class="name">text</span>: <span class="name">qsTr</span>(<span class="string">"A Special Button"</span>)
}
}
</pre>
<p>As you now have the <code>MyControls</code> namespace, you can name the controls after their actual counterparts in the Qt Quick Controls 2 module. You can repeat this process for any control that you wish to add.</p>
<a name="creating-a-custom-style"></a>
<h2 id="creating-a-custom-style">Creating a Custom Style</h2>
<p>There are several ways to go about creating your own styles. Below, we'll explain the various approaches.</p>
<a name="definition-of-a-style"></a>
<h3 >Definition of a Style</h3>
<p>In Qt Quick Controls 2, a style is essentially an interchangeable set of QML files within a single directory. There are two requirements for a style to be <a href="qtquickcontrols2-styles.html#using-styles-in-qt-quick-controls-2">usable</a>:</p>
<ul>
<li>At least one QML file whose name matches a control (for example, <code>Button.qml</code>) must exist.<p>The Default style will be used for any controls that aren't implemented.</p>
</li>
<li>The files must be in a directory in the filesystem or in the <a href="../qtcore/resources.html">resource system</a>.<p>For example, these are all valid paths to a style:</p>
<ul>
<li><code>./myapp -style /home/absolute/path/to/my/style</code></li>
<li><code>./myapp -style :/mystyle</code></li>
<li><code>./myapp -style relative/path/to/my/style</code></li>
<li><code>./myapp -style MyStyle</code></li>
</ul>
<p>The third and fourth paths will be looked up within the QML engine's import path list. This is the same as what happens when you pass <code>Material</code> as the style, for example.</p>
</li>
</ul>
<p>What this means is that you can implement as many controls as you like for your custom style, and place them almost anywhere. It also allows users to create their own styles for your application.</p>
<a name="style-specific-c-extensions"></a>
<h3 >Style-specific C++ Extensions</h3>
<p>Sometimes you may need to use C++ to extend your custom style. There are two ways to expose such types to QML:</p>
<ul>
<li>If the style that uses the type is the only style used by an application, it's enough to register it with the QML engine via <a href="../qtqml/qqmlengine.html#qmlRegisterType">qmlRegisterType</a>():<pre class="cpp">
qmlRegisterType<span class="operator"><</span>ACoolCppItem<span class="operator">></span>(<span class="string">"MyApp"</span><span class="operator">,</span> <span class="number">1</span><span class="operator">,</span> <span class="number">0</span><span class="operator">,</span> <span class="string">"ACoolItem"</span>);
</pre>
<p>See <a href="qtquickcontrols2-gettingstarted.html#using-c-data-from-qml">Using C++ Data From QML</a> for more information about this.</p>
</li>
<li>If the style that uses the type is one of many styles used by an application, it may be better to only register it when necessary. This is the point at which it would make sense to implement your own <a href="../qtqml/qtqml-modules-cppplugins.html">QML plugin</a>.<p>Using a plugin as part of your style is not that much different from using a set of QML files. The only difference is that the plugin and its <code>qmldir</code> file must be present in the same directory as the QML files.</p>
</li>
</ul>
<a name="attached-properties"></a>
<h4 >Attached properties</h4>
<p>It is common for a style to have certain properties or attributes that apply to all controls. <a href="../qtqml/qtqml-syntax-objectattributes.html#attached-properties-and-attached-signal-handlers">Attached properties</a> are a great way of extending an item in QML without having to modify any existing C++ belonging to that item. For example, both the <a href="qtquickcontrols2-material.html">Material</a> and <a href="qtquickcontrols2-universal.html">Universal</a> styles have an attached theme property that controls whether an item and its children will be rendered in a light or dark theme.</p>
<p>As an example, let's add an attached property that controls elevation. Our style will illustrate the elevation with a drop shadow; the higher the elevation, the larger the shadow.</p>
<p>The first step is to add a C++ type that stores the elevation. Since the type will be used for every control supported by our style, and because we may wish to add other attached properties later on, we'll call it MyStyle. Here is <code>MyStyle.h</code>:</p>
<pre class="cpp">
<span class="preprocessor">#ifndef MYSTYLE_H</span>
<span class="preprocessor">#define MYSTYLE_H</span>
<span class="preprocessor">#include <QObject></span>
<span class="preprocessor">#include <QtQml></span>
<span class="keyword">class</span> MyStyle : <span class="keyword">public</span> <span class="type">QObject</span>
{
Q_OBJECT
Q_PROPERTY(<span class="type">int</span> elevation READ elevation WRITE setElevation NOTIFY elevationChanged)
<span class="keyword">public</span>:
<span class="keyword">explicit</span> MyStyle(<span class="type">QObject</span> <span class="operator">*</span>parent <span class="operator">=</span> nullptr);

<span class="type">int</span> elevation() <span class="keyword">const</span>;
<span class="type">void</span> setElevation(<span class="type">int</span> elevation);
<span class="keyword">signals</span>:
<span class="type">void</span> elevationChanged();
<span class="keyword">private</span>:
<span class="type">int</span> m_elevation;
};
QML_DECLARE_TYPEINFO(MyStyle<span class="operator">,</span> QML_HAS_ATTACHED_PROPERTIES)
<span class="preprocessor">#endif // MYSTYLE_H</span>
</pre>
<p><code>MyStyle.cpp</code>:</p>
<pre class="cpp">
<span class="preprocessor">#include "mystyle.h"</span>
MyStyle<span class="operator">::</span>MyStyle(<span class="type">QObject</span> <span class="operator">*</span>parent) :
<span class="type">QObject</span>(parent)<span class="operator">,</span>
m_elevation(<span class="number">0</span>)
{
}
MyStyle <span class="operator">*</span>MyStyle<span class="operator">::</span>qmlAttachedProperties(<span class="type">QObject</span> <span class="operator">*</span>object)
{
<span class="keyword">return</span> <span class="keyword">new</span> MyStyle(object);
}
<span class="type">int</span> MyStyle<span class="operator">::</span>elevation() <span class="keyword">const</span>
{
<span class="keyword">return</span> m_elevation;
}
<span class="type">void</span> MyStyle<span class="operator">::</span>setElevation(<span class="type">int</span> elevation)
{
<span class="keyword">if</span> (elevation <span class="operator">=</span><span class="operator">=</span> m_elevation)
<span class="keyword">return</span>;
m_elevation <span class="operator">=</span> elevation;
<span class="keyword">emit</span> elevationChanged();
}
</pre>
<p>The <code>MyStyle</code> type is special in the sense that it shouldn't be instantiated, but rather used for its attached properties. For that reason, we register it in the following manner:</p>
<pre class="cpp">
qmlRegisterUncreatableType<span class="operator"><</span>MyStyle<span class="operator">></span>(<span class="string">"MyStyle"</span><span class="operator">,</span> <span class="number">1</span><span class="operator">,</span> <span class="number">0</span><span class="operator">,</span> <span class="string">"MyStyle"</span><span class="operator">,</span> <span class="string">"MyStyle is an attached property"</span>);
</pre>
<p>We then copy the existing default Button style, and add the code for a drop shadow (which was taken from the Material Button style). We modify that slightly to ensure that we:</p>
<ul>
<li>Don't bother using the drop shadow when the elevation is <code>0</code></li>
<li>Change the shadow's color depending on whether or not the button has focus</li>
<li>Make the size of the shadow depend on the elevation</li>
</ul>
<pre class="cpp">
layer<span class="operator">.</span>enabled: control<span class="operator">.</span>enabled <span class="operator">&</span><span class="operator">&</span> control<span class="operator">.</span>MyStyle<span class="operator">.</span>elevation <span class="operator">></span> <span class="number">0</span>
layer<span class="operator">.</span>effect: DropShadow {
verticalOffset: <span class="number">1</span>
color: control<span class="operator">.</span>visualFocus <span class="operator">?</span> <span class="string">"#330066ff"</span> : <span class="string">"#aaaaaa"</span>
samples: control<span class="operator">.</span>MyStyle<span class="operator">.</span>elevation
spread: <span class="number">0.5</span>
}
</pre>
<p>With that in place, we can try out our new elevation feature:</p>
<pre class="qml">
import QtQuick 2.6
import QtQuick.Controls 2.0
import MyStyle 1.0
<span class="type">ApplicationWindow</span> {
<span class="name">id</span>: <span class="name">window</span>
<span class="name">width</span>: <span class="number">400</span>
<span class="name">height</span>: <span class="number">400</span>
<span class="name">visible</span>: <span class="number">true</span>
<span class="type">Row</span> {
<span class="name">spacing</span>: <span class="number">20</span>
<span class="name">anchors</span>.centerIn: <span class="name">parent</span>
<span class="type">Button</span> {
<span class="name">text</span>: <span class="string">"Button 1"</span>
}
<span class="type">Button</span> {
<span class="name">text</span>: <span class="string">"Button 2"</span>
<span class="name">MyStyle</span>.elevation: <span class="number">10</span>
}
}
}
</pre>
