Folder Drop Down
Does anyone know what the name for function clicking on an arrowed folder in the list, and when the arrows turns down, it shows all the contents in that folder?

It is what it is - a simple tree example in SWT

What's ugly about it that the equivalent in Swing betters?

Why's that an issue?

Nazi? Oh boy.
1. I could very easily call you an "SWT Nazi" for the above, clearly being as narrow-minded as you choose to perceive I am.
2. The argument that the use of swing equates with supporting mass genocide is a childish one at best, and is horribly inaccurate. I did not state that I intended to visit every person that prefers SWT and put them in an oven, for example.Nor do I believe that George is the perfect scapegoat for my country's loss in a war.
3. The best policy is to keep an open mind, and know how to work with both when it comes to that. The question that I was asked was "how do I do that in Java?" My answer does not fail to answer that question, and I left it there.
4. I have no preference, I am merely aware of the advantages and disadvantages associated with one or the other and recommend the use of one when it fits. George then asked me what a disadvantage of SWT was over Swing, and I gave him an answer.
If you feel that you are too childish, too obnoxious, or too stupid to understand the above and wish to continue trolling, feel free to do it on someone else's time.

Good grief, man, calm down! Big Daddy ain't no troll! You've taken him too seriously. Seriously
Hen-knee-weigh, you never did tell me why the dispose() method is an issue. Why is it?

Anyways.
Also, as JRE's garbage collection becomes better, doing it manually not only goes against the language specifications, but whatever efficiency gained by it becomes less and less meaningful to the point where it is either superfluous or, in some cases, less efficient all together.

I am just not a fan of one-line retorts. The day some fat person on the forums offends me is the day I need to step away from the computer for a while :P

The method is there to manually dispose of native peers which are outwith the runtime's control

But it is possible to implement the JNI in a manner that allows for JRE garbage collection, yes?

Mneh. It is, I guess. AWT must do so. That SWT doesn't is not really a weakness, IMHO. Certainly, in the great Java widget library debate, that particular argument would smack of clutching at straws.
The most common use of SWT is within the Eclipse platform, where such management is taken care of on your behalf anyway

I prefer the term "steatopygous".

I would disagree. According to the language specifications, garbage collection should be automatic. Otherwise, I could just go write a GUI up in C++.
Also, consider a GUI which is running for a relatively extended period of time and is fairly dynamic. Java's garbage collection as you know is designed to collect objects that are unreachable (JNI allows for global references to be reachable, I think.) and therefore no longer in use. If these are always reachable, or have valid references, they are not collected.
However, in SWT (like in the example you posted), garbage collection was not manually done until the END of the program; furthermore, the java garbage collector did nothing because there were still references to the objects. ( I think that at this point it would be almost useless anyways because the references go out of scope and are collected.) But... what if all references to an object are destroyed BEFORE execution of the program ends? what if all the references to hundreds of objects are destroyed? thousands?

Ask the guy at the bakery to do it for you

Which would be more effort. I couldn't do it, because I don't have the C++ nous to. I'm far from alone there.

That example is poor. The dispose method is defined on org.eclipse.swt.widgets.Widget, one is free to call it whenever, on whatever widgets he chooses. When learning SWT, almost all tutorials and books mention that you as a developer are responsible for disposing of the widgets you create. Not perfect, but still, in my opinion, not so big a deal as to render SWT a poor choice of library
georgemca at 2007-7-28 20:03:45 >
Funny how a simple topic is turning into an arguement over Java.
But I'm gonna take jGardner side just because george doesn't think the IPhone won't be a complete failure.
Ah hail, the swing facist!!!

blackmagea at 2007-7-28 20:03:45 >
I never said that SWT was a poor choice of a library in the first place, I was pointing out that expecting the programmer to manually handle the disposal of objects in a language where it is specified that it is done automatically is a weakness in that it is odd. Not only that, but the JRE garbage collector becomes a redundant monster that just sits there.

See, what's happened here is two people have opposing views, but rather than just insist on being right, present reasoned arguments in favour of their corner. Not really an argument, as such

Straw man. I - nor anyone else in that thread - said any such thing :p

Ok, I assumed that was your stance
While its true that the Java language does the heavy lifting of GC, it doesn't mandate that all third-party libraries should take advantage of that. I don't know the reasoning behind why SWT requires manual disposal, but I bet there is some. SWT was conceived by ex-Sun engineers, some of whom worked on AWT and the JFC
The JRE isn't redundant, unless of course, your code consists solely of instances of SWT widgets!
