Detailed Description

The QMimeSource class is an abstraction of objects that provided formatted data of a certain MIME type.

The preferred approach to drag and drop is to use QDrag in conjunction with QMimeData. See Drag and Drop for details.

Constructors and Destructors

◆ ~QMimeSource()

Functions

◆ encodedData()

QByteArray QMimeSource::encodedData ( const char * format ) const

pure virtual

Returns the encoded data of this object in the specified MIME format.

Implemented in QDropEvent, and QMimeDataWrapper.

Referenced by QMimeSourceWrapper::retrieveData().

◆ format()

const char * QMimeSource::format ( int n = 0 ) const

pure virtual

Returns the (i - 1)-th supported MIME format, or 0.

Implemented in QDropEvent, and QMimeDataWrapper.

Referenced by QMimeSourceWrapper::formats(), and provides().

◆ provides()

bool QMimeSource::provides ( const char * mimeType ) const

virtual

Returns true if the object can provide the data in format mimeType; otherwise returns false.

If you inherit from QMimeSource, for consistency reasons it is better to implement the more abstract canDecode() functions such as QTextDrag::canDecode() and QImageDrag::canDecode().

Reimplemented in QDropEvent.

Definition at line 90 of file qmime.cpp.

     for (int i=0; (fmt = format(i)); i++) {
         if (!qstricmp(mimeType,fmt))

     }
