How to show all parents and subclasses of a class

Question

When I'm editing a Java class in Eclipse, when my cursor is over a class variable, I can do Ctrl+T to have a popup that shows all its parents and subclasses. What is the equivalent in IntelliJ?

Example:

Use|r user = new User();

The pipe is my cursor.

Answer 1

In terms of behavior the equivalent of Eclipse Ctrl+T in IntelliJ IDEA is Ctrl+Alt+B

Answer 2

I don't know about prior versions, but in IntelliJ version 13 you can go into your Keymap preferences, search for "Implementations", and bind that to Ctrl+T. It will work very much like the Eclipse equivalent.

Answer 3

Whilst Eclipse includes the type hierarchy and class structure (methods, fields etc.) in a single view, IntelliJ splits these up: In addition to the CTRL+H (or ALT+8) "Type Hierarchy" view, the other relevant IntelliJ window is called "Structure" and can be invoked via ALT+7 (Structure Tool Window) or CTRL+F12(Structure popup).

(Not a direct answer to the exact question posted but would expect others from an Eclipse background may arrive here having googled for "intellij type hierarchy", as I did.)

Answer 4

In IntelliJ 13, it's Navigate > Implementations or CMD + ALT + B by default. Of course, this shortcut can be overridden in your Keymap preferences.

Answer 5

In IntelliJ IDEA 12, it's Navigate > Type Hierarchy (Ctrl+H by default).

Answer 6

Intellij does - in contrast to Eclipse - distinguish between type hierachies and implementation classes. I'm still undecided whether this is a good thing or not (just switched over from Eclipse to Intellij myself)

On a Mac Intellij 14

• Ctrl + H will bring up the type hierarchy showing you sub- and supertypes
• Cmd + Alt + B will show you all implementing classes and subclasses of the interface/class you're interested in
