I am not looking for an article or tutorial.

I need a list of all the available dialog types and options that are valid for each one.

E.g.: How do I adjust the width and height of a dialog? I saw one example of this, but no explanation.

I want to do things like Zenity and yad can do, but the application I'm using uses kdialog and I want to make the most out of it without using an external dialog manager.

I am using kubuntu Linux 18.04, but others who might use my examples may be using other Linux distros and releases.

kdialog --help is probably the closest.

But maybe :
https://man.cx/kdialog
https://develop.kde.org/deploy/kdialog/

Thanks. Those are helpful.
