Did not worked :

setSectionResizeMode(QHeaderView::Fixed); setDefaultSectionSize(10);

@tomendop see documentation for "Layout QML Type". It states:

Note: It is not recommended to have bindings to the x, y, width, or height properties of items in a layout, since this would conflict with the goals of Layout, and can also cause binding loops.

I can't say exactly what is going wrong in your example, but it is basically that you are doing something you aren't supposed to do when you choose to use the Layout mechanism.

I think it can be quite confusing as QML has a number of different ways to manage layout and it isn't always obvious which way is best or most appropriate.

Kind of solved. If I set sizeAdjustPolicy to AdjustToContents and sizePolicy to Maximum, the list widget size will adjust to accomodate items plus small margins around them. I'm quite happy with the result, it would be even better if I could make items equally distribute across available space, but even now it looks good enough.

@hskoglund I confirm that this works nicely. Thanks!

@jsulm said in QApplication::desktop()->screenGeometry() not work in qt6:

What error?

You have to know this ! I mean - is your crystal ball not working today?

Educated guess: If you want to use QDesktopWidget you should insert the header where the class is defined - basic C

QScreen should also be available for PyQt.

@jeanmilost
Your logic seems to be correct.
What you have to do is to move the re-calculation of Scrollbar size & position to the Rectangle rcPageContainer because you are applying scale for that.

Rectangle { id: rcPageContainer objectName: "rcPageContainer" ... /// called when page viewport width changed onWidthChanged: { sbHorz.size = rcPageViewport.width / rcPageContainer.width sbHorz.position = Math.min(Math.max(sbHorz.position, 0.0), 1.0 - (sbHorz.size)); } /// called when page viewport height changed onHeightChanged: { sbVert.size = rcPageViewport.height / rcPageContainer.height sbVert.position = Math.min(Math.max(sbVert.position, 0.0), 1.0 - (sbVert.size)); } }

@firen Read "Size Hints and Size Policies" in https://doc.qt.io/qt-5/qwidget.html

@arjun98 said in How do you properly increase QLineEdit increase icon size/:

ui->searchbar->setClearButtonEnabled(true);
ui->searchbar->QLineEdit::addAction(QIcon(":/img/icons/icon_search.png"), QLineEdit::LeadingPosition);

I have tried loading icon to line edit using above code, it's clearly visibile. and image is not blurred.
try to experiment loading the icon to QLineEdit without any stylesheet being set to it.

@SGaist Yes Thank! It all makes sense now!

Did you check the KDDockWidgets project ? They might have your issue handled.

@Mr-Workalot

First of all, it seems that you don't use any layouts.
Secondly, don't hide your widget by just resizing your dialog (if you are trying to do that). Better hide the widget itself.

To set a width anyway, you can use
QWidget::resize(int w, int h)

Glad you found out and thanks for the detailed solution !

@Jkimmy Thank you for your help.

@JonB
I am passing to QML for this reason. There, placement and dimensioning of graph oblect is very easy to do. I like also the stong division between frontend a nd backend!!!

@mrjj Thanks for the help

@mrjj I tried your code, here's the result:
