Graphical issues when embedded widget is too big about nodeeditor HOT 5 CLOSED

Hi! Thanks for submitting the bug. It it strange that the hight is limited. I will have a look

from nodeeditor.

Could you please share the code where you construct the model's widget?
I can't reproduce the issue.

from nodeeditor.

The specific node I showed on my first post was dynamically generated, so there is no specific code I can give you to duplicate except the whole project. I thought that maybe my "dynamic node creation system" might be the one messing up with the graphics so I added the NaiveDataModel from the connection_colors example to my project and changed the "embeddedWidget" to this piece of code :

QWidget *
  embeddedWidget() override { //return nullptr;
    QFormLayout * layout = new QFormLayout;
    for (int i = 0; i < 15; i++)
    {
        QLineEdit * le = new QLineEdit;
        QString s = QString::number(i);
        layout->addRow(s,le);
    }
    QWidget * widget = new QWidget;
    widget->setLayout(layout);
    widget->setMaximumSize(widget->sizeHint());
    return widget;
  }

Here are the results :

I tried different styling options to be sure that it has nothing to do with it.

Here is another example with more rows :

Also, I'm doing this to set nodeeditor as the central widget of my main project, maybe it's where the problem comes from... :

NodeEditor::NodeEditor()
{
    ::setStyle();

    scene = new FlowScene(registerDataModels());
    this->view = new FlowView(scene);
}

QWidget *
NodeEditor::getWidget()
{
    return ((QGraphicsView *)(this->view));
}
//NodeEditor is one of my class.

Alright, that's not a bug, that's just me.
When I first wrote my function I took your calculator/NumberSourceDataModel.cpp as example where the widget creation is :

_lineEdit->setValidator(new QDoubleValidator());

_lineEdit->setMaximumSize(_lineEdit->sizeHint());

connect(_lineEdit, &QLineEdit::textChanged,
          this, &NumberSourceDataModel::onTextEdited);

_lineEdit->setText("0.0");

So I also used setMaximumSize to create my widget and got a wrong result.

I changed it to setMinimumSize and got :

So I'm finally using :

widget->setMinimumHeight(widget->sizeHint().height());
widget->setMaximumWidth(widget->sizeHint().width());

And now the result is fine :

I guess one does not need to set the size explicitly. From what I know it works just fine with the automatically defined size. Anyway, nice that it finally works.
