Functions

◆ formats()

QStringList QTextEditMimeData::formats ( ) const
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.

hasFormat(), setData(), data()

◆ retrieveData()

QVariant QTextEditMimeData::retrieveData ( const QString mimeType,
QVariant::Type  type 
) const
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().
