Kalk window doesn't show contents

Hi,
I installed Kalk which is a Kirigami based calculator. When I run it is just shows an empty window like this…

I ran it on a terminal and got this output:

82au:~> kalk
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
   QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
   QT_SCREEN_SCALE_FACTORS to set per-screen DPI.
   QT_SCALE_FACTOR to set the application global scale factor.
kf.kirigami: (qrc:/qml/CalculationPage.qml:348:21: Type NumberPad unavailable
                        NumberPad {
                        ^, qrc:/qml/NumberPad.qml:14:5: Type PortraitPad unavailable
        PortraitPad {
        ^, qrc:/qml/PortraitPad.qml:17:5: Type NumberButton unavailable
        NumberButton {text: "√(" ; display: "√"; onClicked: pressed(text);}
        ^, qrc:/qml/NumberButton.qml:14:1: module "QtFeedback" is not installed
    import QtFeedback 5.0
    ^)

Any help on how to get a proper working Kalkulator is much appreciated.

For those who are wondering why I am not using the other default KDE Kcalc app, I want to have like a history list of what I typed in which is not available on the default Kcalc.

KCalc
Ctrl+H - show history.

Another stuff: gnome-calculator, qalculate, speedcrunch.
Or LibreOffice Calc.

Yes. I tired that, but it is not the same as being in the same screen…seems more ‘connected’.

Install with 1 Click install:
libQt5Feedback0

Go to:
https://software.opensuse.org/package/libQt5Feedback0?search_term=libQt5Feedback0

NEVER do a 1-click install when you don’t want to screw up your repository list. ALWAYS do expert installation!

1 Click Installer shows the option to install the package without adding the repository.

Please don’t recommend 1-click installation without knowing the consequences. The forum is full of people with broken repo list because of 1-click installations.

I created a bugreport 1217957 – kalk 23.08.4-1.1 does not work because of missing libQt5Feedback0

I have never had problems with 1 Click Install.
Anyway thanks for creating a bug report.

Thanks. Really appreciate it.
