OK I've solved it.

The entire application has a Stylesheet applied, including settings for a QMenu, and QMenu item, with custom padding.
By overriding the padding for the specific Menu in question I am setting the left padding to be the check icon size smaller than the normal padding size.
Now when the menu is draw it is consistent in padding size with all other menu's.

I still dont think i should have to do it this way, but it's working.

Hi,

Please provide a minimal compilable example to reproduce your issue.

Hi @Kyeiv ,
I didn't realize that you wanted the elements of each line to line up with each other. In this case you can use GridLayout:

import QtQuick import QtQuick.Window import QtQuick.Controls import QtQuick.Layouts Window { GridLayout { anchors.fill: parent columns: 3 //rows: 5 Text { Layout.fillWidth: true text: "Text1a Looooooooog" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } Text { Layout.fillWidth: true text: "Text1b" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } Text { Layout.fillWidth: true text: "Text1c" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } Item { Layout.columnSpan: 3 Layout.fillWidth: true height: 10 Rectangle { height: 1 width: parent.width anchors.centerIn: parent color: "grey" } } Text { Layout.fillWidth: true text: "Text2a" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } Text { Layout.fillWidth: true text: "Text2b Looooooooog" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } Text { Layout.fillWidth: true text: "Text2c" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } ´ Item { Layout.columnSpan: 3 Layout.fillWidth: true height: 10 Rectangle { height: 1 width: parent.width anchors.centerIn: parent color: "grey" } } Text { Layout.fillWidth: true text: "Text3a" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } Text { Layout.fillWidth: true text: "Text3b" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } Text { Layout.fillWidth: true text: "Text3c Looooooooog" horizontalAlignment : Text.AlignHCenter elide: Text.ElideRight } } }

Use QScreen::availableGeometry. It provides the geometry excluding window manager reserved areas.

My sampleColor function was called from the QScrollArea::mouseMoveEvent and the QPoint mousePos was pass in from the mouseEvent there.

What I'm suspecting is that when the image was loaded, the default alignment AlignTop & AlignLeft kicked in, then the mouseMoveEvent followed and the sampleColor function somehow took a snapshot of the imageLabel, before the AlignCenter setting in the constructor. That's why my mouse was still seeing the image at the pre-aligncenter position in the snapshot.

Do you run it on a 2K screen？

Thanks everyone for help.
For me solution is using QGraphicsSimpleTextItem and translate by value calculate by QFontMetricsF::tightBoundingRect / QFontMetricsF::boundingRect.

Now yellow is QGraphicsSimpleTextItem::boundingRect.

QComboBox {background-color:rgb(190,190,190);color:black;padding-left: 10px;padding-right: 30px;border-style: solid;border-width: 0px;}

"padding-left: 10px;"

the padding will shift the combo-box displayed content form the left edge

QComboBox::drop-down {subcontrol-origin: padding; subcontrol-position: top right;width: 40px;border: 0px ;}

"subcontrol-position: top right;"

and the above will position wot text to the right.

Hopefully this helps.
