Subject	Re: [platform-swt-dev] Subclassing Widgets..

In reality, most of the methods in org.eclipse.swt.widgets.*
are package private, and SWT devs continue to use package private methods
for their current development.
Where they have public methods with internal
sematics, these are usually prefixed by "internal_" or "win32_"
or "motif_", so your risk of accidentaly overriding/using these
is very low.
 
So your risk of breaking their code in
a future release is 0%, because subclassing their widgets does not give
you more API - all the additional APIs except few cases are package private
=> invisible to you.
 
 
I should have thought a little before posting.
Shame on me.
 
If they add a public method, and they do
it all the time as SWT is a moving target, and you happen to have the same
method in your code, you are of course screwed.
 
Sorry for the confusion.
