Review request for Plasma, Marco Martin and Sebastian Kügler.
Changes
-------
Cleaned up diff; v1 contained an accidental paste.
Description
-------
DeclarativeMimeData::setData() is QString type, QString data, while \
QMimeData::setData() is QString type, QByteArray data. The former ends up calling the \
latter with data.toLatin1().
I have a need to set a QByteArray payload in the taskbar - X11 WIds, as understood \
e.g. by pagers.
The proposed patch changes the DeclarativeMimeData::setData() signature to QString \
type, QVariant data. The implementation checks whether the QVariant is a byte array, \
and if so, hands it to the base class implementation. If it's not a byte array, it \
checks if it can be converted to a QString, and if so, hands the string version's \
toLatin1() to the base class. If the QVariant is neither a byte array nor convertable \
to a string, nothing is done.
This means behavior changes as follows:
- Byte array support is back.
- Anything that QVariant knows how to convert to a QString is converted. This maybe \
subtly different from how QML "casts" to QString, but I think fits the original \
sentiment of changing the signature to use QString.
- Non-bytearray/string-convertable data is silently dropped.
If this patch is accepted, I would like to backport it to KDE/4.11 as well and make \
use of the improved implementation to restore drag-task-to-pager behavior in the new \
QML task manager.
This addresses bug 322567.
