I use google a lot to find help on JFace/SWT but the only way I find something usefull is when I know the name of the class I want to use. And search again with an other classname related with the first one to finally get to the example of an avanced use of the class (what I wanted for the first time).
Exemple "jface toolbar" doesn't show really interesting results on jface (just some examples on swt). "jface ToolBarManager" show a litle more interesting stuff.
So my question is: where can I find a good advanced documentation on JFace (not only for my toolbar problem) ? A site that list code sample of advance used of JFace components ?
Is this problem of poor documentation due to a framework that is not used a lot ? (execpt in eclipse projet ?)
Thanks in advance
Probably this helps? Furthermore: how about the eclipse integration as well as Javadoc locally and integerated in eclipse so F2 brings up the corresponding docs?

I am currently working on a RCP-Application where i can draw an Internal-Block-Diagram.
Maybe most of you know "Papyrus" from eclipse. This modelling tool provides an Internal-Block-Diagram but I think it is a little bit overloaded so I decided to do it on my own.
I found this awesome tutorial :
https://www.vainolo.com/tutorials/gef-tutorials/
It helped me a lot how GEF works but one thing is not explained. How to draw ports. In the picture below you can see what i am capable of.
I am trying to modify my application that a user is able to draw ports. Like in the next picture:
Does somebody know how this is done in GEF ?
As far as I understand it, it has something to do with the figure of a node. Every node has a figure which is displayed inside the diagram. A port is an extension of the edge of a node and it is not possible to exceed the edge of a node. So I think that papyrus uses a different way to make this happen.
I tried to get the source code of Papyrus but i found nothing neither a documentation about it...
I am thankfully for every opinion.
Papyrus use GMF to create these ports.
You may check classes with containing BorderItem, for example AbstractBorderItemEditPart.
Be careful, the tutorial you are following seems to have been written for GEF3.
As far as I know, there is no "easy" way to manage port in pure GEF3.
There was a major change in GEF last year, you should be able to easily create port with the new GEF4 API.
I know there is a very similar topic to this here but I have looked at the answers posted for it and I feel my problem is slightly different and doesn't need the same approach.
I'm developing an Eclipse plugin which is in essence a GUI that provides the user with different menus, buttons, editing areas etc. It's designed to be an all in one tool to help with coding, re-using code and re-structuring it.
I need a few pointers towards the resources available that can help me build this GUI and have it available as a plugin so I can get the ball rolling. I've looked at the suggestions in the link above but I don't feel like my plugin needs for example a model, view, controller design pattern. I just need the ability to have a GUI pop up when the user starts the plugin and have them interact with it.
Any suggestions or ideas are very much appreciated.
Your GUI has to be an multi-page editor. One (or more) page(s) for the GUI, and one page for the code.
Use the "Plug-in with a multi-page editor" template to get started.
This answer should help you fill out your template code.
When you have a specific question, feel free to ask again.
Take a look at the Tutorials at vogella.de especially the Eclipse plugin section. Those tutorials are usually very good. I learned Eclipse RCP with it.
I am trying to create a screen like this one
Initially I was trying to port a console program to java. I have found things like jcurses and charva but there is almost no documentation on them and I really cant understand how to use them.
So I figured that I could create a console like screen that resembled the one above.
what library / framwork would I be best using. Should I use swing as it if fully portable?
what would be the best approach being that I need to be able to navigate and alter the 00 in the picture above?
Easily usable would be great but as long as it has good documentation that I can learn it from that would be fine.
(Answering as if you're looking for a hex editor.)
http://jhecomponent.sourceforge.net/
http://www.fifesoft.com/hexeditor/
http://hexedit-lib.sourceforge.net/
Played a bit with the fifesoft.com offering, kinda cool.
If you're not looking for a hex editor, can you be more specific? If you just want a cursor-addressable window you'll probably have to suck it up and figure out something like jcurses or libjcsi :)
If you prefer to create a full fledged GUI with Java you could certainly use Swing. I would prefer SWT as a matter of personal taste, the widget library of Eclipse. You will find a lot of snippets and tutorials (same for Swing). Here is the Widget Library.
Here is a discussion about SWT versus Swing.
You could use the table layout manager to create the layout shown in your screenshot. If you rewrite the application from scretch, you should be able to handle the GUI events and update the widgets according to your application needs. You will easily find articles when you search for swt and table. If you would like to keep the code base and just exchange the GUI, I 'm not sure about the best approach. Maybe, the libs jcurses and charva are the way to go.
Unless you are looking to run the app on a headless VM (where a console/tty is all you've got), I'd use Swing. Create a JTable with a custom TableModel (to provide the data) and custom renderers (to provide the hex formatting) and everything should just work. Consider deriving from the various DefaultXXX implementations to save a lot of work.
I wonder if someone can help me... I've been developing VB.Net for years and C++/VB before that. I've also got some PHP experience. I'm now moving to Java to write an app for my Android mobile. I'm trying to use MOTODev Studio (Which extends eclipse)
I've not developed in Java before so it's a bit of a learning curve anyway. I'm fairly confident I'll be able to work out the important bits but I'm in a new IDE in a new language developing for a new platform.
As I'm new to Java, I was hoping to be able to rely on auto-code generation, intellisense, etc. I'm starting to think this was either very optimistic or I'm using eclipse very poorly.
For example, I know I need to override the OnClickListener() event but am unsure of the exact syntax. In VS, I'd just start typing Override in a class and up would pop intellisense with everything I can override and the appropriate signature, however, in eclipse none of the intellisense options seem to apply when I type public voidor #Override. Is this because I'm doing something wrong/is eclipse intellisense incomplete not very good?
In VS there's a bar at the top of the code page which lists objects in the file on the left and methods of the current object on the right. Does eclipse have an equivalent? If so, where?
I've managed to use the IDE to the extent that I've got a "Hello World" installed on my mob so it's more code generation techniques than windows/dialogues/etc.
I suppose what I really need is for someone to recommend some good resources to help me transition. I'd also appreciate any comments or advice from others that have done similar
Thanks in advance
So you learning three items at once
Language (Java)
Platform (Android)
Tool (Eclipse)
Here are my two cents for each of them:
Java - besides annotations guide already mentioned by Falmarri all java tutorials on oracle site are worth seeing you can find them here
Android - From my point of view very good entering points into android development are Android Developer Dev guide and API Demos project which demonstrates many android aspects ( You can add this project into your workspace in Eclipse via ->New Android Project-> Select from sample ->Choose target version -> Click OK , Voila you have new project in your workspace with a lot of useful android related code, describing many advanced and not so advanced topics). BTW Android developers blog is worth reading but
it usually covers more advanced topics
Eclipse - Falmarri already pointed and pretty good tutorial about Eclipse, I from my side would suggest to start from Help-> Help Contents -> Java Development User Guide
It covers all basic tasks and concepts. For your particular problem with overriding ( actually implementing) an interface method you've to first indicate that your class implements View.OnClickListener via class MyClass implements OnClickListener at this point eclipse will notice that you claiming to implement interface but didn't actually implemented some of it methods ( in this situation onClick(View v)) and will mark class declaration with error marker. Go to your class declaration and press Ctrl + 1 ( also known as "quick fix") and you will get some options to fix broken code. At the other hand if you really want to override parent class method you can press Ctrl + Space in a class body ( e.g not inside the method) and you will get option to override avalible methods.
Hope it helps

yes, it's the default java perspective. Have you even installed the IDE yet?
http://www.vogella.de/articles/Eclipse/article.html
I'm not entirely sure I fully understand your questions, but if I'm in a Java class in Eclipse that implements some Interface and I want to implement methods I either select the quick fix (Ctrl+1) for the compiler error telling me I'm not implementing the Interface or I trigger content assist (Ctrl+Space) in the class body to get a list of methods to override. And with the bar you mention, do you mean something like the breadcrumb navigation (Alt+Shift+B)?
I've been trying to create a GUI using netbeans, that includes a dialog similar to Netbean's own "property dialog" that appears when designing. ie. a dialog that contains a table that can be expanded by tree nodes. Something like the dialog on this page, http://platform.netbeans.org/tutorials/nbm-property-editors.html
As far as I can understand, the page I linked to describes a custom editor I can set up for use within netbeans while designing - I'm just looking for a way to doing something similar for my actual application I'm writing. Is there an easy way to do this?
I came across this and have tried it but it doesn't quite work in the same way as the standard Netbeans dialog. weblogs.java.net/blog/timboudreau/archive/2008/06/egads_an_actual.html
Any tips greatly appreciated.
This will sound flip... but I am being serious.
The easiest way to do this is to write your app using the NetBeans RCP platform.
You may want to look at the Swing Application Framework, too.
There are a couple SAF samples integrated into NetBeans... You can read about them here: http://netbeans.org/kb/docs/java/gui-saf.html
I could not find a property editor dialog sample, though.
I found a couple other pointers, using this query: http://www.google.com/search?q=how+to+write+a+property+editor+dialog+in+swing
