## Detailed Description
该QClipboard类提供窗口系统剪贴板。
剪贴板提供复制和粘贴应用程序之间的数据的简单机制。
QClipboard支持相同的数据类型[QDrag](qdrag.html)确实,并采用类似的机制。对于高级剪贴板的使用读[Drag and Drop](index.htm)。
有一个在应用程序中的单个QClipboard对象,作为访问[QApplication.clipboard](qapplication.html#clipboard)( ) 。
例如:
```
QClipboard *clipboard = [QApplication](qapplication.html).clipboard();
[QString](qstring.html) originalText = clipboard->text();
...
clipboard->setText(newText);
```
QClipboard具有一些方便的功能来访问常用数据类型:[setText](qclipboard.html#setText)( )允许Unicode文本的交换和[setPixmap](qclipboard.html#setPixmap)()和[setImage](qclipboard.html#setImage)( )允许应用程序之间QPixmaps和QImages的交流。该[setMimeData](qclipboard.html#setMimeData)( )函数是极大的灵活性:它可以让你添加任何[QMimeData](qmimedata.html)复制到剪贴板中。有相应的getter为每个这些,例如[text](qclipboard.html#text)( )[image](qclipboard.html#image)()和[pixmap](qclipboard.html#pixmap)( ) 。你可以通过调用清除剪贴板[clear](qclipboard.html#clear)( ) 。
使用这些功能的一个典型例子如下:
```
void DropArea.paste()
{
const QClipboard *clipboard = [QApplication](qapplication.html).clipboard();
const [QMimeData](qmimedata.html) *mimeData = clipboard->mimeData();
if (mimeData->hasImage()) {
setPixmap(qvariant_cast<[QPixmap](qpixmap.html)>(mimeData->imageData()));
} else if (mimeData->hasHtml()) {
setText(mimeData->html());
setTextFormat([Qt](qt.html).RichText);
} else if (mimeData->hasText()) {
setText(mimeData->text());
setTextFormat([Qt](qt.html).PlainText);
} else {
setText(tr("Cannot display data"));
}
```
### Notes for X11 Users
* The X11 Window System has the concept of a separate selection and clipboard. When text is selected, it is immediately available as the global mouse selection. The global mouse selection may later be copied to the clipboard. By convention, the middle mouse button is used to paste the global mouse selection.
* X11 also has the concept of ownership; if you change the selection within a window, X11 will only notify the owner and the previous owner of the change, i.e. it will not notify all applications that the selection or clipboard data changed.
* Lastly, the X11 clipboard is event driven, i.e. the clipboard will not function properly if the event loop is not running. Similarly, it is recommended that the contents of the clipboard are stored or retrieved in direct response to user-input events, e.g. mouse button or key presses and releases. You should not store or retrieve the clipboard contents in response to timer or non-user-input events.
* Since there is no standard way to copy and paste files between applications on X11, various MIME types and conventions are currently in use. For instance, Nautilus expects files to be supplied with a `x-special/gnome-copied-files` MIME type with data beginning with the cut/copy action, a newline character, and the URL of the file.
### Notes for Mac OS X Users
Mac OS X支持保存在查找操作的当前搜索字符串单独发现的缓冲区。这一发现剪贴板可以通过指定访问的[FindBuffer](qclipboard.html#Mode-enum)模式。
### Notes for Windows and Mac OS X Users
* Windows and Mac OS X do not support the global mouse selection; they only supports the global clipboard, i.e. they only add text to the clipboard when an explicit copy or cut is made.
* Windows and Mac OS X does not have the concept of ownership; the clipboard is a fully global resource so all applications are notified of changes.

## Type Documentation
```
QClipboard.Mode
```
该枚举类型是用来控制系统剪贴板中的一部分是由[QClipboard.mimeData](qclipboard.html#mimeData)( )[QClipboard.setMimeData](qclipboard.html#setMimeData)( )和相关函数。
| Constant | Value | Description |
| --- | --- | --- |
| `QClipboard.Clipboard` | `0` | 表示数据应该存储和从全局剪贴板中检索。 |
| `QClipboard.Selection` | `1` | 表示数据应该存储和从全局鼠标选择检索。支持`Selection`是只设置一个全局鼠标选择(例如X11 )系统。 |
| `QClipboard.FindBuffer` | `2` | 表示数据应该存储和查找缓冲区中检索。此模式用于保持搜索字符串在Mac OS X。 |

```
(QString, QString) QClipboard.text (self, QString subtype, Mode mode = QClipboard.Clipboard)
```
这是一个重载函数。
返回亚型剪贴板文本_subtype_,或一个空字符串,如果剪贴板中不包含任何文本。如果_subtype_为null ,任何亚型是可以接受的,并且_subtype_被设置为所选择的子类型。
该_mode_参数用来控制哪些系统剪贴板的一部分使用。如果_mode_ is [QClipboard.Clipboard](qclipboard.html#Mode-enum),文本从全局剪贴板中检索。如果_mode_ is [QClipboard.Selection](qclipboard.html#Mode-enum),该文本从全局鼠标选择检索。
为共同的价值观_subtype_是“普通”和“HTML” 。
请注意,多次调用该函数,例如从一个关键的事件处理程序,可能会很慢。在这种情况下,你应该使用`dataChanged()`信号代替。
