This reverts commit 0e318bfc.

Implement WatchModel::data() to return the right values
for Qt::EditRole, obsoleting the role matching in the delegate.
Similarly, handle Qt::EditRole in setData(), leaving only
'Change watch expression' in the delegate, which removes
and recreates a row, causing crashes when done in setData().

Tooltips can still be improved.

The symbols are now exported in current 4.7.1.
So it does compile.

This assert is simply wrong. A component
might reparent the item inside an item,
that has no instance.

We have to call classBegin() on creation.

Set the parent if no parentItem exists
Call componentComplete

There can be notifications from the instance
after a model node has been deleted.
We now ignore those.

Check if object is not 0 and we are not called back from the
destructor.

anchors

ChildItems of siblings can not be anchored to a item.

the root item

This is preventing visual artefacts.

If the NodeInstance is allready removed the formeditor item isn't
removed.

Add getter for id in node instances.

Split isAnchoredBy() in isAnchoredBySigbling() and
isAnchoredByChildren()

Fix node instance view notifications and settings in the model.
Now the old node instance view is detached and the new one is attached.
The test runs again. Also fixes a notification.

Use the node instance id member instead of the model node id
Prevents a crash because the model node is allready invalid
and has no id anymore.

The rewriter is not anymore in the view list, so the reset function has
to be changed.

RewriterView and NodeInstanceView was not notified about a model change.

This is preventing a crash if the nodeinstance is invalid.
