Adding a GraphicsScene into a QLabel
-
On my main.cpp i am using w.show(); with w is my MainWindow where i have put the label the scene and the central widget . I am kind of new to qt so i don t know a lot of things , is using a QWidget will make the work easier ?
@chrisLucr QLabel is usually used to show text and images, for QGraphicsScene I would use QWidget.

I have a problem displaying two labels, the label "label" is displayed with no problem ( it has some buttons adjusted Horizontally ) and the second label "label1" is not being displayed ( it contains a scene which has a view , in the scene i have a title and a picture ). This is the code i am trying to use.
widget1 = new QWidget; setCentralWidget(widget1); label1 = new QLabel(widget1); scene = new QGraphicsScene(label1); vue = new QGraphicsView(scene); label1->move(100,100); label = new QLabel(widget1); layout = new QHBoxLayout(label); label->resize(500,100);It's my first time using QGraphicsScene/View and it is confusing me a little bit.
hi @chrisLucr and welcome
I think you're confusing some things.
The GraphixsView object will show/display your QGraphicsScene
What you did was creating a Scene and a view as children of your QLabel. But that will not lead to automatic resizing of the QGraphicsView nor to an automatic show() call.
this, for example, will create and show a QScene inside a view
QGraphicsScene scene; scene.addText("Hello, world!"); QGraphicsView view(&scene); view.show();I assume, you can simply add your QGraphicsView to a layout, no need to go the way over a Label.

i have tried this ,
but it does not work too,
i still can t see the scene in my window, all i am seeing are the buttons i have made
( the picture show exactely what i am trying to do :
)
```widget2 = new QWidget(widget1); scene = new QGraphicsScene(widget2); vue = new QGraphicsView(scene); -

well i have tried it and i deleted the line (view.show();) since i don t need two windows to appear but still does not work , i am trying to display the scene/view on the same window as the other labels.
@jsulm i don t call it cause when i do two windows appear when i need only one. this is the code in my main.cpp where i am showing the window ( i think it does the job ?? )
```
QApplication a(argc, argv);
MainWindow w;
w.show();return a.exec(); -

widget2 = new QWidget(widget1); scene = new QGraphicsScene(); vue = new QGraphicsView(scene, widget2); widget2->show(); vue->show(); -
@chrisLucr if your issue is solved, please don't forget to mark your post as such. Thanks
