[PyQt] Converting C++ to Python

[Rajeev J Sebastian]

Hi Phil,

Thanks for the response, but I would like some clarification:

I should do

if (self.textInteractionFlags() & QtCore.Qt.TextEditable):
    ... do some stuff ...

is that correct ?

Also, I have another question.

In the diagramscene app, in the QGraphicsScene subclass, I do the following:

for item in self.items():
    print item

Which prints the following:
<PyQt4.QtGui.QGraphicsItem object at 0xa7a7a0ac>
<__main__.DiagramItem object at 0xa7a7acac>
<__main__.DiagramItem object at 0xa7a7abac>
<__main__.Arrow object at 0xa7a7ad2c>


The problem is that the first element *should* actually be a
<__main__.DiagramTextItem> rather than a QGraphicsItem.
(DiagramTextItem is a subclass of QGraphicsTextItem).

In other words, for some reason, python subclasses of
QGraphicsTextItem arent recognized correctly when the same are
returned from C++.

I can see that QGraphicsTextItem gets some special treatment in the
.sip files ... would this affect its use ?
