QT5.9 Text is not smooth

Akshay Bhavsar

Hi

I am using QT 5.9 in my project. Prior to that I was using QT5.5

Below is difference I am seeing in QT 5.5 and QT5.9

QT5.5

QT5.9

It seems text is not smooth in QT 5.9

Please suggest me if I am missing something.

Thanks.

Hi
ok.
as far as i know, there is no flag to change font smoothing.
The 5.9 does look smoothed also but not as much as in 5.5

There does seems to be something changed

but if that applies to your platform i dont know.

Can someone please suggest any possible solution?

@Akshay-Bhavsar What are you using to display the text?

Akshay Bhavsar

I am using QML and QT desktop for display

I meant, which Type of object/class are you using to display the text?

If it is the Text type, see if the renderType and renderTypeQuality settings can help: https://doc.qt.io/qt-6/qml-qtquick-text.html#renderType-prop

Note: Qt 5.9 reached end-of-life in May 2020. Since you are upgrading from Qt 5.5, I strongly suggest you upgrade to at least Qt 5.12 LTS

I am using Text Type
I have set renderType: Text.NativeRendering
renderTypeQuality is not available in this version
antialiasing : true

& I am not allowed to change QT version.

JKSH

renderTypeQuality is not available in this version

Ah sorry... I was looking at the Qt 6 documentation.

Does changing renderType change the look?

I am not allowed to change QT version.

That's a bit unfortunate

renderType doesnt change the look.

@Akshay-Bhavsar I hope you find a solution
