@Bonnie Thank you for pointing me in the right direction. I turns out the issue wasn't height, or min-height, but rather an inherited padding, that just happened to make it look like it was expanding to the full height of the QHBoxLayout.

Is it possible to to extend QLabel and implement my own paintEvent() that draws the text and draws the svg image?

It seems to work, but would problaby take alot of effort to get it right (i.e. to get the image in the right location everytime).

void MypLabel::paintEvent(QPaintEvent* event) { QPainter painter(this); const auto pos = QPoint(0, 16); painter.drawText(pos, this->text()); const auto posPixMap = QPoint(30, 0); auto size = QSize(16, 16); auto pixMap = QIcon(":/Resources/smiley.svg").pixmap(size); painter.drawPixmap(posPixMap, pixMap); }

@Bonnie said in UI Stretch with QtCreator:

Because the three layout widgets are not added to any layout. They are child widgets of centralWidget, but they are not added to its layout.
A widget will only be resized and moved to fit the window when it is added to a layout whose parent widget is either the window or also added to an layout whose.....

Thanks for help me, that works

Hi,

Did you also set the stretch factor when inserting the widgets in the layout ?

Hi, this is old now but in case someone else finds this:
I managed to solve this problem by using
setSizeConstraint(QtWidgets.QLayout.SetNoConstraint)
for a layout holding the QLineEdit widget. Actually it wasn't the layout holding the widget, but the layout holding that layout, so you may need to experiment to find out where you need to make this update (or just use SetNoConstraint for all your layouts)
I hope this helps someone!
