## Detailed Description
该QMimeData类提供一个容器,用于数据记录有关它的MIME类型的信息。
QMimeData是用来描述可以存储在信息[clipboard](qclipboard.html),并经由传输[drag and drop](index.htm)机制。 QMimeData对象,它们与相应的MIME类型保存数据关联起来,以确保信息可以在应用程序之间进行安全转移,并在同一应用程序内各地复制。
通常使用创建QMimeData对象`new`并供给到[QDrag](qdrag.html) or [QClipboard](qclipboard.html)对象。这是为了让Qt的管理他们所使用的内存。
单个QMimeData对象可以使用几种不同的格式的同时存储相同的数据。该[formats](qmimedata.html#formats)( )函数返回按优先顺序排列的可用格式的列表。该[data](qmimedata.html#data)( )函数返回一个MIME类型相关联的原始数据,并[setData](qmimedata.html#setData)()允许您设置一个MIME类型的数据。
对于最常见的MIME类型, QMimeData提供方便的功能来访问数据:
| Tester | Getter | Setter | MIME Types |
| --- | --- | --- | --- |
| [hasText](qmimedata.html#hasText)() | [text](qmimedata.html#text)() | [setText](qmimedata.html#setText)() | `text/plain` |
| [hasHtml](qmimedata.html#hasHtml)() | [html](qmimedata.html#html)() | [setHtml](qmimedata.html#setHtml)() | `text/html` |
| [hasUrls](qmimedata.html#hasUrls)() | [urls](qmimedata.html#urls)() | [setUrls](qmimedata.html#setUrls)() | `text/uri-list` |
| [hasImage](qmimedata.html#hasImage)() | [imageData](qmimedata.html#imageData)() | [setImageData](qmimedata.html#setImageData)() | `image/` * |
| [hasColor](qmimedata.html#hasColor)() | [colorData](qmimedata.html#colorData)() | [setColorData](qmimedata.html#setColorData)() | `application/x-color` |
例如,如果你写一个接受URL的小工具拖拽,你最终会编写这样的代码:
```
void MyWidget.dragEnterEvent([QDragEnterEvent](qdragenterevent.html) *event)
{
if (event->mimeData()->hasUrls())
event->acceptProposedAction();
}
void MyWidget.dropEvent([QDropEvent](qdropevent.html) *event)
{
if (event->mimeData()->hasUrls()) {
foreach ([QUrl](qurl.html) url, event->mimeData()->urls()) {
...
}
}
}
```
有三种方法用于在QMimeData对象存储自定义数据:
1. 自定义数据可以直接存储在一个QMimeData对象作为[QByteArray](qbytearray.html) using [setData](qmimedata.html#setData)( ) 。例如:
```
[QByteArray](qbytearray.html) csvData = ...;
QMimeData *mimeData = new QMimeData;
mimeData->setData("text/csv", csvData);
```
2. 我们可以继承QMimeData和重新实现[hasFormat](qmimedata.html#hasFormat)( )[formats](qmimedata.html#formats)()和[retrieveData](qmimedata.html#retrieveData)( ) 。
3. 如果发生在一个单一的应用程序中的拖放操作,我们可以继承QMimeData ,并在其中添加额外的数据,并使用[qobject_cast](qobject.html#qobject_cast)( )在接收器的放置事件处理程序。例如:
```
void MyWidget.dropEvent([QDropEvent](qdropevent.html) *event)
{
const MyMimeData *myData =
qobject_cast<const MyMimeData *>(event->mimeData());
if (myData) {
// access myData's data directly (not through QMimeData's API)
}
}
```
### Platform-Specific MIME Types
在Windows上,[formats](qmimedata.html#formats)( )也将返回的MIME数据可自定义格式,使用`x-qt-windows-mime`亚型,表明它们代表了非标准格式的数据。该格式将采取以下形式:
```
application/x-qt-windows-mime;value="<custom type>"
```
下面是自定义MIME类型的示例:
```
application/x-qt-windows-mime;value="FileGroupDescriptor"
application/x-qt-windows-mime;value="FileContents"
```
该`value`声明的每个格式的描述,其中的数据被编码的方式。
在Windows上, MIME格式并不总是直接映射到剪贴板格式。 Qt提供[QWindowsMime](index.htm)映射的剪贴板格式,打开标准的MIME格式。类似地,[QMacPasteboardMime](index.htm)MIME映射到Mac的口味。

```
QVariant QMimeData.colorData (self)
```
返回一个颜色,如果存储在所述对象数据代表颜色(MIME类型`application/x-color`) ,否则返回一个空的变体。
A [QVariant](qvariant.html)被使用,因为[QMimeData](qmimedata.html)属于[QtCore](index.htm)库,而[QColor](qcolor.html)属于[QtGui](index.htm)。若要转换[QVariant](qvariant.html)到[QColor](qcolor.html),只需使用[qvariant_cast](qvariant.html#qvariant_cast)( ) 。例如:
```
if (event->mimeData()->hasColor()) {
[QColor](qcolor.html) color = qvariant_cast<[QColor](qcolor.html)>(event->mimeData()->colorData());
...
}
```
**See also** [hasColor](qmimedata.html#hasColor)( )[setColorData](qmimedata.html#setColorData)()和[data](qmimedata.html#data)( ) 。

```
QVariant QMimeData.imageData (self)
```
返回[QVariant](qvariant.html)存储[QImage](qimage.html)如果该对象可以返回一个图像,否则返回一个空的变体。
A [QVariant](qvariant.html)被使用,因为[QMimeData](qmimedata.html)属于[QtCore](index.htm)库,而[QImage](qimage.html)属于[QtGui](index.htm)。若要转换[QVariant](qvariant.html)到[QImage](qimage.html),只需使用[qvariant_cast](qvariant.html#qvariant_cast)( ) 。例如:
```
if (event->mimeData()->hasImage()) {
[QImage](qimage.html) image = qvariant_cast<[QImage](qimage.html)>(event->mimeData()->imageData());

此功能被引入Qt的4.4 。
```
QVariant QMimeData.retrieveData (self, QString mimetype, Type preferredType)
```
返回一个变量与给定的_type_包含的数据由指定的MIME类型_mimeType_。如果对象不支持的MIME类型或特定变量类型,则返回一个空的变体来代替。
调用此函数由一般[data](qmimedata.html#data)( ) getter和通过便捷的getter ([text](qmimedata.html#text)( )[html](qmimedata.html#html)( )[urls](qmimedata.html#urls)( )[imageData](qmimedata.html#imageData)()和[colorData](qmimedata.html#colorData)())。您可以重新实现它,如果你想使用一个自定义的数据结构,而不是一个(存储数据[QByteArray](qbytearray.html),这是[setData](qmimedata.html#setData)( )提供) 。那么你就还需要重新实现[hasFormat](qmimedata.html#hasFormat)()和[formats](qmimedata.html#formats)( ) 。
**See also** [data](qmimedata.html#data)( ) 。
```
QMimeData.setColorData (self, QVariant color)
```
在对象的颜色数据设置为给定_color_。
颜色对应的MIME类型`application/x-color`。
**See also** [colorData](qmimedata.html#colorData)( )[hasColor](qmimedata.html#hasColor)()和[setData](qmimedata.html#setData)( ) 。
```
QMimeData.setData (self, QString mimetype, QByteArray data)
```
设置与由下式给出的MIME类型相关联的数据_mimeType_到指定的_data_。
对于数据的最常见的类型,你可以调用高级功能[setText](qmimedata.html#setText)( )[setHtml](qmimedata.html#setHtml)( )[setUrls](qmimedata.html#setUrls)( )[setImageData](qmimedata.html#setImageData)()和[setColorData](qmimedata.html#setColorData)( )来代替。
请注意,如果你想使用自定义数据类型中的项目视图拖放操作,您必须注册为一个Qt[meta type](qmetatype.html)使用[Q_DECLARE_METATYPE](qmetatype.html#Q_DECLARE_METATYPE)()宏,并实现流运算符吧。流运营商然后必须与所登记的[qRegisterMetaTypeStreamOperators](qmetatype.html#qRegisterMetaTypeStreamOperators)()函数。
**See also** [data](qmimedata.html#data)( )[hasFormat](qmimedata.html#hasFormat)( )[QMetaType](qmetatype.html)和[qRegisterMetaTypeStreamOperators](qmetatype.html#qRegisterMetaTypeStreamOperators)( ) 。
```

**See also** [html](qmimedata.html#html)( )[hasHtml](qmimedata.html#hasHtml)( )[setText](qmimedata.html#setText)()和[setData](qmimedata.html#setData)( ) 。
```
QMimeData.setImageData (self, QVariant image)
```
在对象中的数据设置为给定_image_。
A [QVariant](qvariant.html)被使用,因为[QMimeData](qmimedata.html)属于[QtCore](index.htm)库,而[QImage](qimage.html)属于[QtGui](index.htm)。从转换[QImage](qimage.html)至[QVariant](qvariant.html)是隐式的。例如:
```
mimeData->setImageData([QImage](qimage.html)("beautifulfjord.png"));
