Embedded widget with wrong size when content has changed

[yvanblanchard]

Hello,

I have a node with an embedded widget (QtLabel). This Label widget contained a quite long text, and after updating the flow graph, this node was updated and text was shorter. Problem is that the lable widget kept its previous size, instead of being resized as expected. The node (container) of this widget was correctly resized (smaller), but not the widget child..

Before:

After:

Any idea ?

Can you try to use a QLayout to manage the size of the label?

QWidget* embeddedWidget() {
    auto* widget = new QWidget;
    auto* lay = new QVBoxLayout; // or QHBoxLayout
    auto* label = new QLabel; // your label
    lay->addWidget(label);
    widget->setLayout(lay);
    return widget;
}

@mariusalexander thank you, but I had already used layout for my embedded widget. it seems like this issue is possibly related to a Qt bug (related to zooming effect): #121

...when also using 'embeddedWidgetSizeUpdated' in eventFilter of the widget (Qlabel orother), it works fine!
