I am using InteliJ IDEA

Show Diagram

action on the base class, but I see only single class. Is there any way to see all of the child classes as well? I imaging there is a swich to turn on, a bug in IDE 🤔 BTW Is there any other tool to draw nice class hierarchy?

iirc right click on that node and tell it to add the children

Try right-clicking the project in the Project tool window and then selecting Show Diagram.

@Vampire Is there an option to all all children at once? @Marit van Dijk This is wired sometimes works, fine other times I see bunch of module dependenciesŚ instead of classes nested in the given package

The approach is, that it shows the class and its ancestors (at least for Java classes). And if you do right click and select "Show implementations", it gives you a list of all descendents and you can select which to add to the diagram. I assume it is the same for Kotlin files.

For me (on MacOS) it works to press select the node, press

cmd+B

, then

cmd+A

, then

enter

Yes, that's exactly what I described, just with Keyboard shortcuts 🙂

thx @Wout Werkman - I didn't realised that I can ad all of them at once. Even better they stick after repenting the diagram. BTW @Vampire similar point, but it was not clear for me that I can add all of them easily 😉
