How to show all parents and subclasses of a class in IntelliJ IDEA?

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 subc

Answer 1

Ctrl+U - go to base class

Ctrl+Alt+B - got to implementation. Type parts of class name to narrow down the list

Ctrl+H - open type hierarchy tool window

Ctrl+Alt+U - peek class/interface inheritance hierarchy

Answer 2

For Mac Users, the shortcut is

^(control) + h

Answer 3

Navigate | Type Hierarchy Ctrl+H will show similar information, however in the Panel. You can Float and Unpin the Panel so that it appears on the fixed display position only when you use the keyboard shortcut.

Answer 4

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

Answer 5

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

Answer 6

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.)
