@Chris-Kawa thank you, it helped to set the margins!

@mrjj I actually want to print to an actual printer. So, using a PDF in between is not an option.

Just as I said: the margins of the QPrinter::pageLayout() do not work as one would expect. In order to be able to print close to the border, you have to turn on full page mode and set the margins of the QPrinter directly. I am not entirely sure (as I have a huge code base involved converting wxWidgets to Qt), but it looks like setting the margins of QPrinter actually prints with that margin (in contrast to what the documentation suggests). For me the problems are now solved.

@J.Hilk said in Set fixed margin/spacing/padding between Widgets/Layouts:

@wrekler you have to set the margin and spacing of the QLayout item to 0 as well, not only in the StyleSheet. I believe those are 2 different pairs of shoes.

@JonB said in Set fixed margin/spacing/padding between Widgets/Layouts:

To clarify what @J-Hilk is saying (which I believe to be correct): a QLayout is not a QWidget and so cannot have its attributes affected via a stylesheet rule (sadly). That has to be done via explicit, back-end code.

Here we go! That was the problem! Layout cannot be affected by a stylesheet file! Now I know how styling layout works! Thank!

Hi
Seem you just want to paint it using a border.
Not having a border inside image.
That you can easy do when painting it.

Like

void MiniSVG::paintEvent(QPaintEvent* ) { QPainter p(this); QSvgRenderer r; // this would normally be a member.. r.load(QString(":/7XB_smaller.svg")); r.render(&p, rect().adjusted(64, 64, -64, -64)); }

sample to play with

if its only this image u need this for, you can also just change page size. ( view box)

that should work too.

If you put your buttons in a QButtonGroup you could simply store the button id so you can programmatically check it when loading your document.

but the cursor detect the margins

What margins?
Do you mean for something inside the docks?

@Chris-Kawa Thanks. I agree it seems like a bug, and have now reported it: https://bugreports.qt.io/browse/QTBUG-51359. I figure the widget-inside-widget would be a workable alternative, but was hoping to avoid that route. C'est la vie.

@bam500 Yes, using GridLayout is an option so that the vertical alignment of the texts are equal.

I think I was finally able to solve the problem.

As the solution suggested by @hskoglund is Windows-specific, I decided to first investigate a bit deeper the other options presented by @J-Hilk

It turned out that the Qt::WindowStaysOnTopHint flag was not set for our main window. I am now setting that flag in our main windows's constructor, and afterwards show it full screen. This seems to work.

Thanks again for your suggestions!

You could put the content of the outer rectangles inside a component.
This way the code would be hidden away in a separate qml file.

cheers
