QWindowsMime Class Reference
[QtGui module]

Detailed Description

The QWindowsMime class maps open-standard MIME to Window Clipboard formats.

Qt's drag-and-drop and clipboard facilities use the MIME standard. On X11, this maps trivially to the Xdnd protocol, but on Windows although some applications use MIME types to describe clipboard formats, others use arbitrary non-standardized naming conventions, or unnamed built-in formats of Windows.

By instantiating subclasses of QWindowsMime that provide conversions between Windows Clipboard and MIME formats, you can convert proprietary clipboard formats to MIME formats.

Qt has predefined support for the following Windows Clipboard formats:

An example use of this class would be to map the Windows Metafile clipboard format (CF_METAFILEPICT) to and from the MIME type image/x-wmf. This conversion might simply be adding or removing a header, or even just passing on the data. See Drag and Drop for more information on choosing and definition MIME types.

You can check if a MIME type is convertible using canConvertFromMime() and can perform conversions with convertToMime() and convertFromMime().
