I am trying to follow http://www.jetbrains.com/idea/features/uml_class_diagram.html I have a few classes so when I do Ctrl + Alt + U I only see all classes and just Extends relationships.
Please note that I have set the "Diagrams" options in my settings to show one to many etc.
I do not see One to One, One to Many relationships at all ? I have used JPA OneToOne Annotations and they dont turn up at all?
Pressing Ctrl Shift F12 does not do anything?
Can someone please explain?
Actually it appears there is a "Show Dependencies" icon. Toggling that and toggling it again actually shows my relationships one to one, one to many etc
In order to see these relationships you have to right click in the diagram and select "Show Edge Labels".
This works in IntelliJ IDEA 2021.1.1 (Ultimate Edition), April 30, 2021
Using 9th icon from left side of image ,we can show relationships between classes.
This option is only available in Intelij ultimate edition.

While I'm uncertain of the precise names for them - I'm referring to these:
There is a strip of these on both the left and right sides. I simply want to "reclaim" the real estate (since I have the keyboard shortcuts memorized).
Oh I see they're also at the bottom..
Why is it that GUI designers want to continually cram more stuff on the screen.. at the expense of usable working /editing areas..
Found it: Under _View | _Tool Buttons
Dear JetBrains: thanks for making this configurable after all.
You could also click on the square icon on bottom left to toggle the Tool Buttons.
I find it extremely difficult to spot the currently selected tab in Intellij, if using the Darcula theme. I've looked for a workaround and I was not able to find any solution besides disabling the "Use in Editor Tabs" checkbox in Settings->Appearance&Behavior->FileColors.
This issue has been reported by several other users (e.g. this question), but I can't seem to solve it for the current version of Intellij/Darcula.
Thanks
One possible fix is to use the single tab model, where you set the maximum open tabs to 1. You can use open-recent, open class, and the project explorer to navigate around your codebase. I switched to this model after seeing a colleague working this way last year and I'm enjoying it. It took me a few days to get used to it, but having the tool enforce the single tab approach helps because you are basically forced to work this way.
You can try Material Theme plugin for intellij. It has a dark theme like Darcula and it would underline and highlight your current tab.
And if you think long term perspective, actually Engineer Dollery is correct. When you get more and more experience with intellij, you also feel that working with multiple tabs is really a time waste. Single tab mode is much efficient.
Because intellij provides plenty of navigation tools like Ctrl + Shift + N , Ctrl + tab , Ctrl + E , Ctrl + Shift + E , you really don't need tabs. These shortcut keys make sure your finger tips remain on keyboard and save the time you have to deal with switching to touch pad/mouse and again to keyboard when you try to switch the tabs in multiple tabs mode. If you count this time saving for a week/month, actually its a huge amount. :))
I've moved from Eclipse to IntelliJ IDEA and I like the its responsiveness.
In Eclipse I use ObjectAid to assist in designing my application structure. IntelliJ IDEA does have a UML diagram but it got really annoying when it keeps re-adjusting my diagram layout to what it thinks is a neat structure. Everytime I add/remove a class, it will re-adjust the layout. It may look neat, but it makes little sense to me. I like to manually place my class model in the exact place I leave it. Why oh why does IntelliJ think it knows best? Can I change this behavior? I can't find any settings in the settings menu.
You can disable this behaviour in the preferences under "Tools" -> "Diagrams". There is an option "Do relayout when new elements were added" which you need to disable.
Note: IntelliJ 2016.3
Just started working on E-R diagrams for the first time and I can't seem to be able to underline. Any suggestions?
as you are not creating a flowchart, but an er, you should change your palette :) click on the left side of your screen where it says "flowchart", and select "er". now use the tool "attribute" from this new palette. check out the properties of this one! no underlining..... but!! primary key :D dia is even semantically correct.
you should use the tools from this palette exclusively when creating er diagrams. so use "entity" for that box in your screenshot that says "person".
draw lines between entities and relations with the line tool from the er palette, use the generic line tool from the basic tools on your top left for the attributes. and make sure everything is connected via their handles (displayed on each object as tiny tiny x:es). makes it easier to move things around :)
good luck!
Trying to reverse-engineer existing project and it would be of great help to see how classes collaborate/depend on each other. Is there a way to build project-wide UML diagram (or class diagram of any kind) in IntelliJ IDEA using build-in functionallity or using some free plugin?
Right click on your package no matter which. Click Diagrams > Show Diagram (Ctrl+Alt+Shift+U). You will see your package in diagram editor.
Now:
You can expand (E) or collapse (C) all nodes.
You can show dependencies
You can show many attributes of nodes (constructors, methods, properties...)
You can drag&drop other packages from project explorer.
So, play with it a bit and i think you will achieve what you need.
This is how it could looks like:
