Promoted Widget within a Promoted Widget programmatically

[ByForeward]

Hi

Widget Promotion

Based on several forums I managed to promote a graphicsView accordingly.
The issue comes when within the promoted class I need to create a QLabel (within the graphicsView) that itself needs to be promoted.

1. Promote Graphics View :) (through the designer)
2. Add QLabel Widget within graphicsView (programatically) :)


label= new QLabel();
label->setFixedSize(320, 320);
label->setText("Test Label");
proxy = myScene->addWidget(label);
proxy->setZValue(0);

3. try to promote the generated label (That is within the graphicsView) to another class in code
Since i only have access to the label in the code and not via the designer. :confused:

How do I promote a QLabel to a specified class within code? (Not through the designer)

Your assistance is appreciated

Regards

There is no such thing as widget promotion in code.

Widget promotion, in the context of Designer, is the mechanism by which the user can add a widget of some class C in design mode and make Designer, in the generated code setting up this UI, actually instantiate a specified subclass of C. E.g. if you have a QLabel-derived class MyLabel, you can add a QLabel in design mode and promote it to MyLabel. You will be limited, in design mode, to the QLabel interface (properties, signals), but Designer will generate code that instantiates a MyLabel and sets its QLabel-inherited properties accordingly.

If you write the code directly, just instantiate the correct class. Instead of

QLabel *label = new QLabel();
, do something like

MyLabel *label = new MyLabel();

Yes Thanks,

Your proposition of correctly instantiating a class would work.:cool:
(I don't know why i did not think of that... I'm still learning the ropes, i guess)

Thanks yeye ;)
