Re: [platform-swt-dev] SWT-Design Decisions

Not to mention, one of the requirements for SWT was that the class
hierarchy could fit on a single PowerPoint slide using a font size Steve
could still see.

Hi Tom,
These questions have been asked before.
1) Interfaces have various advantages and drawbacks. Defining them for the
purposes of Javadoc is not in keeping with the small side of the toolkit.
What's an "SWT-Binding writer"?
2) There could be abstact classes but that would introduce a layer,
increase the size of the toolkit and make things slower, and possibly
harder to debug and maintain.
3) The idea was to minimize the number of constants in the toolkit. Read
the Javadoc for class SWT.

<platform-swt-dev@xxxxxxxxxxx> Decisions
Hi,
Last night I browsed the SWT-Source and asked myself some questions:
1. Why are there no interface definitions like IWidget, IComposite, ...?
This would make life of SWT-Binding writers easier to stay in sync
with the SWT-API, wouldn't it? Another pro is that the javadoc is
stored in the interface and not duplicated in the real
implementation as it is now.
2. Why are the no AbstractClasses used to extract platform-independent
code parts of Widgets?
3. Looking back was it really a good decision to put all constants into
SWT class?
Thanks for your thoughts.
Tom
