<!-- $$$QMimeData-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QMimeData class provides a container for data that records information about its MIME type.</p>
<p>QMimeData is used to describe information that can be stored in the <a href="qclipboard.html">clipboard</a>, and transferred via the <a href="dnd.html">drag and drop</a> mechanism. QMimeData objects associate the data that they hold with the corresponding MIME types to ensure that information can be safely transferred between applications, and copied around within the same application.</p>
<p>QMimeData objects are usually created using <tt>new</tt> and supplied to <a href="qdrag.html">QDrag</a> or <a href="qclipboard.html">QClipboard</a> objects. This is to enable Qt to manage the memory that they use.</p>
<p>A single QMimeData object can store the same data using several different formats at the same time. The <a href="qmimedata.html#formats">formats</a>() function returns a list of the available formats in order of preference. The <a href="qmimedata.html#data">data</a>() function returns the raw data associated with a MIME type, and <a href="qmimedata.html#setData">setData</a>() allows you to set the data for a MIME type.</p>
<p>For the most common MIME types, QMimeData provides convenience functions to access the data:</p>
<table class="generic">
<thead><tr class="qt-style"><th >Tester</th><th >Getter</th><th >Setter</th><th >MIME Types</th></tr></thead>
<tr valign="top" class="odd"><td ><a href="qmimedata.html#hasText">hasText</a>()</td><td ><a href="qmimedata.html#text">text</a>()</td><td ><a href="qmimedata.html#setText">setText</a>()</td><td ><tt>text/plain</tt></td></tr>
<tr valign="top" class="even"><td ><a href="qmimedata.html#hasHtml">hasHtml</a>()</td><td ><a href="qmimedata.html#html">html</a>()</td><td ><a href="qmimedata.html#setHtml">setHtml</a>()</td><td ><tt>text/html</tt></td></tr>
<tr valign="top" class="odd"><td ><a href="qmimedata.html#hasUrls">hasUrls</a>()</td><td ><a href="qmimedata.html#urls">urls</a>()</td><td ><a href="qmimedata.html#setUrls">setUrls</a>()</td><td ><tt>text/uri-list</tt></td></tr>
<tr valign="top" class="even"><td ><a href="qmimedata.html#hasImage">hasImage</a>()</td><td ><a href="qmimedata.html#imageData">imageData</a>()</td><td ><a href="qmimedata.html#setImageData">setImageData</a>()</td><td ><tt>image/</tt> *</td></tr>
<tr valign="top" class="odd"><td ><a href="qmimedata.html#hasColor">hasColor</a>()</td><td ><a href="qmimedata.html#colorData">colorData</a>()</td><td ><a href="qmimedata.html#setColorData">setColorData</a>()</td><td ><tt>application/x-color</tt></td></tr>

<p>For example, if your write a widget that accepts URL drags, you would end up writing code like this:</p>
<pre class="cpp"> <span class="type">void</span> MyWidget<span class="operator">::</span>dragEnterEvent(<span class="type"><a href="qdragenterevent.html">QDragEnterEvent</a></span> <span class="operator">*</span>event)
{
<span class="keyword">if</span> (event<span class="operator">-</span><span class="operator">></span>mimeData()<span class="operator">-</span><span class="operator">></span>hasUrls())
event<span class="operator">-</span><span class="operator">></span>acceptProposedAction();
}
<span class="type">void</span> MyWidget<span class="operator">::</span>dropEvent(<span class="type"><a href="qdropevent.html">QDropEvent</a></span> <span class="operator">*</span>event)
{
<span class="keyword">if</span> (event<span class="operator">-</span><span class="operator">></span>mimeData()<span class="operator">-</span><span class="operator">></span>hasUrls()) {
foreach (<span class="type"><a href="qurl.html">QUrl</a></span> url<span class="operator">,</span> event<span class="operator">-</span><span class="operator">></span>mimeData()<span class="operator">-</span><span class="operator">></span>urls()) {
<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
}
}
}</pre>
<p>There are three approaches for storing custom data in a QMimeData object:</p>
<ol class="1">
<li>Custom data can be stored directly in a QMimeData object as a <a href="qbytearray.html">QByteArray</a> using <a href="qmimedata.html#setData">setData</a>(). For example:<pre class="cpp"> <span class="type"><a href="qbytearray.html">QByteArray</a></span> csvData <span class="operator">=</span> <span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>;
<span class="type">QMimeData</span> <span class="operator">*</span>mimeData <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QMimeData</span>;
mimeData<span class="operator">-</span><span class="operator">></span><a href="qmimedata.html#setData">setData</a>(<span class="string">"text/csv"</span><span class="operator">,</span> csvData);</pre>
</li>
<li>We can subclass QMimeData and reimplement <a href="qmimedata.html#hasFormat">hasFormat</a>(), <a href="qmimedata.html#formats">formats</a>(), and <a href="qmimedata.html#retrieveData">retrieveData</a>().</li>
<li>If the drag and drop operation occurs within a single application, we can subclass QMimeData and add extra data in it, and use a <a href="qobject.html#qobject_cast">qobject_cast</a>() in the receiver's drop event handler. For example:<pre class="cpp"> <span class="type">void</span> MyWidget<span class="operator">::</span>dropEvent(<span class="type"><a href="qdropevent.html">QDropEvent</a></span> <span class="operator">*</span>event)
{
<span class="keyword">const</span> MyMimeData <span class="operator">*</span>myData <span class="operator">=</span>
qobject_cast<span class="operator"><</span><span class="keyword">const</span> MyMimeData <span class="operator">*</span><span class="operator">></span>(event<span class="operator">-</span><span class="operator">></span>mimeData());
<span class="keyword">if</span> (myData) {
<span class="comment">// access myData's data directly (not through QMimeData's API)</span>
}
}</pre>
</li>
</ol>
<a name="platform-specific-mime-types"></a>
<h3>Platform-Specific MIME Types</h3>
<p>On Windows, <a href="qmimedata.html#formats">formats</a>() will also return custom formats available in the MIME data, using the <tt>x-qt-windows-mime</tt> subtype to indicate that they represent data in non-standard formats. The formats will take the following form:</p>
<pre class="cpp"> application<span class="operator">/</span>x<span class="operator">-</span>qt<span class="operator">-</span>windows<span class="operator">-</span>mime;value<span class="operator">=</span><span class="string">"<custom type>"</span></pre>
<p>The following are examples of custom MIME types:</p>
<pre class="cpp"> application<span class="operator">/</span>x<span class="operator">-</span>qt<span class="operator">-</span>windows<span class="operator">-</span>mime;value<span class="operator">=</span><span class="string">"FileGroupDescriptor"</span>
application<span class="operator">/</span>x<span class="operator">-</span>qt<span class="operator">-</span>windows<span class="operator">-</span>mime;value<span class="operator">=</span><span class="string">"FileContents"</span></pre>
<p>The <tt>value</tt> declaration of each format describes the way in which the data is encoded.</p>
<p>On Windows, the MIME format does not always map directly to the clipboard formats. Qt provides <a href="qwindowsmime.html">QWindowsMime</a> to map clipboard formats to open-standard MIME formats. Similarly, the <a href="qmacpasteboardmime.html">QMacPasteboardMime</a> maps MIME to Mac flavors.</p>

<p>Returns a <a href="qvariant.html">QVariant</a> storing a <a href="qimage.html">QImage</a> if the object can return an image; otherwise returns a null variant.</p>
<p>A <a href="qvariant.html">QVariant</a> is used because <a href="qmimedata.html">QMimeData</a> belongs to the <a href="qtcore.html">QtCore</a> library, whereas <a href="qimage.html">QImage</a> belongs to <a href="qtgui.html">QtGui</a>.

<p>Returns a variant with the given <i>type</i> containing data for the MIME type specified by <i>mimeType</i>. If the object does not support the MIME type or variant type given, a null variant is returned instead.</p>
<p>This function is called by the general <a href="qmimedata.html#data">data</a>() getter and by the convenience getters (<a href="qmimedata.html#text">text</a>(), <a href="qmimedata.html#html">html</a>(), <a href="qmimedata.html#urls">urls</a>(), <a href="qmimedata.html#imageData">imageData</a>(), and <a href="qmimedata.html#colorData">colorData</a>()). You can reimplement it if you want to store your data using a custom data structure (instead of a <a href="qbytearray.html">QByteArray</a>, which is what <a href="qmimedata.html#setData">setData</a>() provides). You would then also need to reimplement <a href="qmimedata.html#hasFormat">hasFormat</a>() and <a href="qmimedata.html#formats">formats</a>().</p>

<p>Sets the data associated with the MIME type given by <i>mimeType</i> to the specified <i>data</i>.</p>
<p>For the most common types of data, you can call the higher-level functions <a href="qmimedata.html#setText">setText</a>(), <a href="qmimedata.html#setHtml">setHtml</a>(), <a href="qmimedata.html#setUrls">setUrls</a>(), <a href="qmimedata.html#setImageData">setImageData</a>(), and <a href="qmimedata.html#setColorData">setColorData</a>() instead.</p>
<p>Note that if you want to use a custom data type in an item view drag and drop operation, you must register it as a Qt <a href="qmetatype.html">meta type</a>, using the <a href="qmetatype.html#Q_DECLARE_METATYPE">Q_DECLARE_METATYPE</a>() macro, and implement stream operators for it. The stream operators must then be registered with the <a href="qmetatype.html#qRegisterMetaTypeStreamOperators">qRegisterMetaTypeStreamOperators</a>() function.</p>
