The QMimeData class provides a container for data that records information about its MIME type.
QMimeData is used to describe information that can be stored in the clipboard, and transferred via the drag and drop 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.
QMimeData objects are usually created using new and supplied to QDrag or QClipboard objects. This is to enable Qt to manage the memory that they use.
A single QMimeData object can store the same data using several different formats at the same time. The formats() function returns a list of the available formats in order of preference. The data() function returns the raw data associated with a MIME type, and setData() allows you to set the data for a MIME type.
For the most common MIME types, QMimeData provides convenience functions to access the data:
TesterGetterSetterMIME Types
hasText() text() setText() text/plain
hasHtml() html() setHtml() text/html
hasUrls() urls() setUrls() text/uri-list
hasImage() imageData() setImageData() image/ *
hasColor() colorData() setColorData() application/x-color
For example, if your write a widget that accepts URL drags, you would end up writing code like this:
void MyWidget::dragEnterEvent(QDragEnterEvent *event)
{
if (event->mimeData()->hasUrls())
event->acceptProposedAction();
}
void MyWidget::dropEvent(QDropEvent *event)
{
if (event->mimeData()->hasUrls()) {
foreach (QUrl url, event->mimeData()->urls()) {
...
}
}
}
There are three approaches for storing custom data in a QMimeData object:
Custom data can be stored directly in a QMimeData object as a QByteArray using setData(). For example: QByteArray csvData = ...;
QMimeData *mimeData = new QMimeData;
mimeData->setData("text/csv", csvData);
We can subclass QMimeData and reimplement hasFormat(), formats(), and retrieveData().
If the drag and drop operation occurs within a single application, we can subclass QMimeData and add extra data in it, and use a qobject_cast() in the receiver's drop event handler. For example: void MyWidget::dropEvent(QDropEvent *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
On Windows, formats() will also return custom formats available in the MIME data, using the x-qt-windows-mime subtype to indicate that they represent data in non-standard formats. The formats will take the following form:
application/x-qt-windows-mime;value="<custom type>"
The following are examples of custom MIME types:
application/x-qt-windows-mime;value="FileGroupDescriptor"
application/x-qt-windows-mime;value="FileContents"
The value declaration of each format describes the way in which the data is encoded.
On Windows, the MIME format does not always map directly to the clipboard formats. Qt provides QWindowsMime to map clipboard formats to open-standard MIME formats. Similarly, the QMacPasteboardMime maps MIME to Mac flavors.
See also QClipboard, QDragEnterEvent, QDragMoveEvent, QDropEvent, QDrag, QWindowsMime, QMacPasteboardMime, and Drag and Drop.
|
protected |
| QtCore.QMimeData.QMimeData | ( | ) |
Constructs a new MIME data object with no data in it.
| new void QtCore.QMimeData.Clear | ( | ) |
Removes all the MIME type and data entries in the object.
|
virtual |
Reimplemented from QtCore.QObject.
| new QByteArray QtCore.QMimeData.Data | ( | string | mimetype | ) |
Returns the data stored in the object in the format described by the MIME type specified by mimeType.
See also setData().
| new void QtCore.QMimeData.Dispose | ( | ) |
|
virtual |
Returns a list of formats supported by the object. This is a list of MIME types for which the object can return suitable data. The formats in the list are in a priority order.
For the most common types of data, you can call the higher-level functions hasText(), hasHtml(), hasUrls(), hasImage(), and hasColor() instead.
See also hasFormat(), setData(), and data().
| new bool QtCore.QMimeData.HasColor | ( | ) |
Returns true if the object can return a color (MIME type application/x-color); otherwise returns false.
See also setColorData(), colorData(), and hasFormat().
|
virtual |
Returns true if the object can return data for the MIME type specified by mimeType; otherwise returns false.
For the most common types of data, you can call the higher-level functions hasText(), hasHtml(), hasUrls(), hasImage(), and hasColor() instead.
See also formats(), setData(), and data().
| new bool QtCore.QMimeData.HasHtml | ( | ) |
Returns true if the object can return HTML (MIME type text/html); otherwise returns false.
See also setHtml(), html(), and hasFormat().
| new bool QtCore.QMimeData.HasImage | ( | ) |
Returns true if the object can return an image; otherwise returns false.
See also setImageData(), imageData(), and hasFormat().
| new bool QtCore.QMimeData.HasText | ( | ) |
Returns true if the object can return plain text (MIME type text/plain); otherwise returns false.
See also setText(), text(), hasHtml(), and hasFormat().
| new bool QtCore.QMimeData.HasUrls | ( | ) |
Returns true if the object can return a list of urls; otherwise returns false.
URLs correspond to the MIME type text/uri-list.
See also setUrls(), urls(), and hasFormat().
| new void QtCore.QMimeData.RemoveFormat | ( | string | mimetype | ) |
Removes the data entry for mimeType in the object.
This function was introduced in Qt 4.4.
|
protectedvirtual |
Returns a variant with the given type containing data for the MIME type specified by mimeType. If the object does not support the MIME type or variant type given, a null variant is returned instead.
This function is called by the general data() getter and by the convenience getters (text(), html(), urls(), imageData(), and colorData()). You can reimplement it if you want to store your data using a custom data structure (instead of a QByteArray, which is what setData() provides). You would then also need to reimplement hasFormat() and formats().
See also data().
| new void QtCore.QMimeData.SetData | ( | string | mimetype, |
| QByteArray | data | ||
| ) |
Sets the data associated with the MIME type given by mimeType to the specified data.
For the most common types of data, you can call the higher-level functions setText(), setHtml(), setUrls(), setImageData(), and setColorData() instead.
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 meta type, using the Q_DECLARE_METATYPE() macro, and implement stream operators for it. The stream operators must then be registered with the qRegisterMetaTypeStreamOperators() function.
See also data(), hasFormat(), QMetaType, and qRegisterMetaTypeStreamOperators().

getset |
Returns a color if the data stored in the object represents a color (MIME type application/x-color); otherwise returns a null variant.
A QVariant is used because QMimeData belongs to the QtCore library, whereas QColor belongs to QtGui. To convert the QVariant to a QColor, simply use qvariant_cast(). For example:
if (event->mimeData()->hasColor()) {
QColor color = qvariant_cast<QColor>(event->mimeData()->colorData());
...
}
Sets the color data in the object to the given color.
Colors correspond to the MIME type application/x-color.

getprotected |
|
getset |
Returns a string if the data stored in the object is HTML (MIME type text/html); otherwise returns an empty string.
Sets html as the HTML (MIME type text/html) used to represent the data.
|
getset |
Returns a QVariant storing a QImage if the object can return an image; otherwise returns a null variant.
A QVariant is used because QMimeData belongs to the QtCore library, whereas QImage belongs to QtGui. To convert the QVariant to a QImage, simply use qvariant_cast(). For example:
if (event->mimeData()->hasImage()) {
QImage image = qvariant_cast<QImage>(event->mimeData()->imageData());
...
}
Sets the data in the object to the given image.
A QVariant is used because QMimeData belongs to the QtCore library, whereas QImage belongs to QtGui. The conversion from QImage to QVariant is implicit. For example:
mimeData->setImageData(QImage("beautifulfjord.png"));

staticget |
|
getset |
Returns a plain text (MIME type text/plain) representation of the data.
Sets text as the plain text (MIME type text/plain) used to represent the data.
|
getset |
Returns a list of URLs contained within the MIME data object.
URLs correspond to the MIME type text/uri-list.
Sets the URLs stored in the MIME data object to those specified by urls.
URLs correspond to the MIME type text/uri-list.
