Explicitly delete the root project item when closing a QmlProject.

When adding a multiselection of images outside the qrc-path,
the file dialog is created every time, causing great
delays due to DBUS problems. Create a context struct
keeping the dialogs around.

When multiple threads share the Bind instance in a Document and do
lookup on the objects contained inside, that may trigger a new object
creation in some situations - which needs to be synchronized.

This avoids asserts and catches exceptions

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.

ChildItems of siblings can not be anchored to a item.

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.
