whats the proper way to subclass?

What i do is i just go to the source and add 'extends whatever....' class
i want to extend.

So where do i specify 'whatever' so 'whatever' will automatically show up
in the extends section of the code?

and implements????

Victor,

In the New Java Class wizard, there's a box labeled Superclass. You can
type the name of the class you wish to extend there, or press the Browse
button to locate the class. Beneath that there is a list labeled
Interfaces. You can use the Add and Remove classes you'd like to implement.

Hope this helps,

- Jeff

When i create a new class,
there's a place where i can specify 'Superclass'
(i guess this is where i could put 'Dialog', which'
is what i wanna subclass)

problem is when i click browse, there's not much:
Choose a type says:
java.lang.Object
(which is what was in there in the first place(i guess it is the default,
cause i sure as hell didnt do it)

Matching types says:
Object

Qualifyer says:
(well, it specifies the run time jar)
java.lang -C:\Program files\Java\jre.1.5.0_01\lib\rt.jar

where can i pull Dialog from?

Just clear the text java.lang.Object in the textfield at the top and
start typing Dialog. It should auto filter and allow you to select the
class you want from the list in the middle.

To see the class 'Dialog', it must be on the classpath
of your project. This can be done by hand, using
the project properties.

But, it sounds like you are writing a plugin.
In that case, you should use the plugin.xml editor
to add a dependency to the plugin that declares
the 'Dialog' class - org.eclipse.jface?

To understand better what classes you can see
when, read this uber-frequently-asked-question:
