Create a commercial-quality Eclipse IDE by IBM

ANTLR, DSL, eclipse No Comments »

This should be a good tutorial. I need to look into it:

http://www.ibm.com/developerworks/edu/os-dw-os-ecl-commplgin1.html

I know there is an excellent tutorial in Chinese. It demos how to craft a source code editor using Eclipse JFace Text Framework and a bit ANTLR. The link is here.

Mouse-click on Buttons Doesn’t Work in Ubuntu 9.10?

eclipse 2 Comments »

After installing Ubuntu 9.10, eclipse became naughty. I tried to create a Java Project. However, mouse-click on Next/Finish buttons didn’t work. The buttons got focused, but no response. So you have to press ENTER or SPACE to actually press the buttons.

A quick fix here: create a shell script. For example, eclipse.sh:

export GDK_NATIVE_WINDOWS=1
/home/frankdu/Developer/eclipse/eclipse

Then add executable permission to the file: chmod +x ./eclipse.sh

Every time you run eclipse.sh to launch eclipse. At least we can be happy for a while. Please see http://www.eclipse.org/forums/index.php?t=msg&goto=498640& for more information.

Quick Note: How to check out eclipse source code?

eclipse No Comments »

The source code can be checked out with CVS or subversion. I assume that you are running eclipse. We will use the CVS tool.

1. Open the CVS view: Window -> Show View -> Other -> CVS -> CVS Repositories

2. Add a new repository location, using the settings below:
Host: dev.eclipse.org
Repository path: /cvsroot/eclipse
User: anonymous
Connection Type: pserver
Port: use default. If it doesn’t work or you are behind firewall, use 80.

And, that’s it! It should works now.

Quick Note: Which eclipse version to install for Mac OS X?

eclipse No Comments »

Since eclipse 3.5, you will find 3 versions for Mac OS X users: carbon, cocoa, and cocoa-64.

A simple note here: Install carbon version for Leopard and earlier versions. Try Cocoa 64-bit for Snow Leopard.

It took me a couple of minutes. Therefore, a quick note here.

GEF involves many concepts as it establishes its MVC convention. You may find tutorials from eclipse official site spend most paragraphs in concept explanation.

Here is a very nice tutorial focusing on step-by-step application. It’s not long, around 80 pages in PDF version:

Eclipse: Dynamically Adjust Widget Size and Reflow a Form Page

eclipse, java No Comments »

Let’s say you need to dynamically adjust a widget size, and then update scroll bar information. Things are pretty simple, if we understand how eclipse layout works.

I have a PageBook widget, and wish to resize the form page as selection changes. Here is the important part:

  1.  
  2. // other code
  3. pageBook.showPage(parent);
  4. Point computeSize = pageBook.computeSize(SWT.DEFAULT, SWT.DEFAULT);
  5.  
  6. // the following two statements are very important, because they will tell swt/jface how to layout.
  7. GridDataFactory.defaultsFor(pageBook).align(SWT.FILL, SWT.TOP).span(2, 1).hint(SWT.DEFAULT, computeSize.y + 20).applyTo(pageBook);
  8.  
  9. pageBook.layout(true, true);
  10.  
  11. // reflow the form
  12. form.reflow(true);
  13.

Code Snippet to use PageBook

eclipse, java No Comments »

Below is very straightforward code snippet to use PageBook. It is used together with eclipse form. Therefore you will see widgets are created via the FormToolkit class.

  1.  
  2. toolkit = new FormToolkit(container.getDisplay());
  3. form = toolkit.createScrolledForm(container);
  4.  
  5. Composite parent = form.getBody();
  6. GridLayoutFactory.fillDefaults().numColumns(1).applyTo(parent);
  7.  
  8. // create a table as selection provider
  9. final Table table = toolkit.createTable(parent, SWT.BORDER | SWT.VIRTUAL);
  10. table.setHeaderVisible(true);
  11. table.setLinesVisible(true);
  12. for(int i=1; i<=12; i++){
  13.         TableItem item = new TableItem(table, 0);
  14.         item.setText("Item " + i);
  15. }                              
  16.  
  17. toolkit.createLabel(parent, "Selected pagebook:");
  18.  
  19. // create a PageBook
  20. final ScrolledPageBook pageBook = toolkit.createPageBook(parent, SWT.NONE);
  21. GridDataFactory.defaultsFor(pageBook).grab(true, true).applyTo(pageBook);
  22.  
  23. // create PageBook controls
  24. for(int i=0; i<table.getItemCount(); i++){
  25.         TableItem item = table.getItem(i);
  26.         Composite pageContainer = pageBook.createPage(item.getText());
  27.         GridLayoutFactory.fillDefaults().numColumns(1).applyTo(pageContainer);
  28.        
  29.         toolkit.createLabel(pageContainer, item.getText());
  30.         toolkit.createText(pageContainer, "to be edited");
  31.        
  32.         pageBook.showPage(item.getText());
  33. }
  34.  
  35. pageBook.showEmptyPage();
  36.  
  37. // add selection listener, and show relative PageBook on selection
  38. table.addSelectionListener(new SelectionAdapter(){
  39.         public void widgetSelected(SelectionEvent e) {
  40.                 TableItem item = (TableItem) e.item;
  41.                 pageBook.showPage(item.getText());
  42.         }                      
  43. });
  44.

Finally Learned to Use Common Navigator Framework (CNF)

eclipse No Comments »

Today I finally went through the CNF tutorials by Michael. It’s a famous online one, located at

http://scribbledideas.blogspot.com/2006/07/pdf-versions-now-available.html

My task is to customize all menu items in our customized navigator. There are generally 2 ways to contribute menus in Common Navigator Framework:

1. Contribute via platform popup menu extensions (viewerContribution and objectContribution).

2. Via ActionProvider inside CNF.

I wish to remove all contributions in the additions section (mainly by objectContribution) and Import/Export actions (via ActionProvider).

To achieve the first aim, set the navigator viewer subnode <popupMnu allowsPlatformContributions=”false” >…</popupMenu>.

To achieve the second goal, remove the following insertionPoint from <popupMenu />:

  1.  
  2. <insertionPoint
  3. name="group.port"
  4. separator="true">
  5. </insertionPoint>
  6.

Eclipse Headless Build Error “no protocol: ${eclipseBaseURL}”

eclipse 2 Comments »

When setting up headless build in eclipse, you may encountered an error like:

C:\plugin-build\build-target-3.4.1\eclipse\plugins\org.eclipse.pde.build_3.4.1.R34x_v20080805\templates\headless-build\customTargets.xml:18: java.net.MalformedURLException: no protocol: ${eclipseBaseURL}

According to my solution, this is caused by a relative path when you invoke antRunner. For exmaple, if you use a relative path to set the builder:

-Dbuilder=pnstool
or
-Dbuilder=../pnstool

Then the error will appears. If you use an absolute path, the error will be fixed. An example is below:

java -jar %ECLIPSE_HOME%/startup.jar -application org.eclipse.ant.core.antRunner -buildfile %ECLIPSE_HOME%/plugins/org.eclipse.pde.build_3.4.1.R34x_v20080805/scripts/build.xml -Dbuilder=c:/plugin-build/pnstool
