Kai,
What about QGraphicsWidget? There seems no visual editor for it.
Besides, it is not clear on how to add a new sub class QDelarativeItem to item
library. I tried the following:
I. in myplugin.cpp:
qmlRegisterType<QDeclarativeItem>("test_mtf_plugin",1,0,"QDeclarativeItem");
2. in .metainfo
metainfo>
<node name="test_mtf_plugin/QDeclarativeItem" showInItemLibrary="true"
category="Bauhaus - Basic" isContainer="true"
icon=":/fxplugin/images/item-icon.png">
<inherits name="Qt/Item" />
<propertyDefaultValue name="width" type="int" defaultValue="600"/>
<propertyDefaultValue name="height" type="int" defaultValue="400"/>
<itemlibraryrepresentation name="MTF Item"
icon=":/fxplugin/images/item-icon.png">
<property name="width" type="int" value="200"/>
<property name="height" type="int" value="200"/>
</itemlibraryrepresentation>
</node>
</metainfo>
Notice that I use "<inherits name="Qt/Item" />" in the metainfo file, or it
will not show in item library.
Although with these codes, qmldesigner can show a item in the library, when I
drag the item on top of an item, qtcreator crashes with:
property list interface not fully implemented for Class
QDeclarativeListProperty<QObject> in property "data" !
Property list interface not fully implemented for Class
QDeclarativeListProperty<QObject> in property "data" !
Property list interface not fully implemented for Class
QDeclarativeListProperty<QObject> in property "data" !
Property list interface not fully implemented for Class
QDeclarativeListProperty<QObject> in property "data" !
terminate called after throwing an instance of 'QmlDesigner::RewritingException'
If I change " test_mtf_plugin" to "Qt", everything is OK. Should I always put
my customized class to "Qt" ?
Best regards,
John Chen

Hi,
the idea of QuickDesigner is obviously to lay out stuff visually. To do
this, the things you drag&drop have to implement an interface.
QuickDesigner needs a way to e.g. set a width, height, position, and
tell the thingy to paint itself. That's why we cannot handle 'arbitrary'
QObject based classes (at least QuickDesigner is not able to do anything
interesting with it).
You're right in that QuickDesigner only supports items inheriting from
QDeclarativeItem. It would be indeed possible to also add support for
QWidget based stuff, but it would be a major effort, and given the fact
that we don't support QWidget bindings for Qml, and there is already a
visual editor for QWidgets (QtDesigner), it's unlikely that we look into
this any time soon.
