SWT/Devel/Gtk/Useful Eclipse shortcuts

Often you will find that Eclipse has many tools useful for dealing with the nuances of the SWT code base.

Call Hierarchy

This tool, bound by default to Ctrl + Alt + H, is very useful for looking at which functions/methods call one another. I usually bind this to F1 (since I use it often and F1 is unbound), but that is totally a matter of personal preference.

If you are interested in what calls a certain method, simply move the cursor on it and type Ctrl + Alt + H, your keybinding, or right click, select "Open Call Hierarchy". A tabbed view will open in the bottom portion of Eclipse (by default) and a function hierarchy will be displayed.

Function Declaration

This tool, bound to F3 by default, displays the original declaration of a function. To use it, move the cursor over the name of the function/method and press F3, your keybinding, or right click and select "Open Declaration".

Sometimes functions/methods are overridden somewhere and you need to see where this occurs. To view the implementation of a function/method, hover the cursor over the function/method name, and hold Ctrl. A menu will appear: click "Open Implementation" instead of "Open Declaration".
