JFace Data Binding/FAQ

Does Data Binding depend upon Eclipse?

The core Data Binding plug-in only depends upon org.eclipse.equinox.common and no other parts of Eclipse. There are parts of Data Binding that depend upon SWT/JFace but these have been broken out into a separate plug-in, org.eclipse.jface.databinding. For a discussion of why the core depends upon equinox common see bug 153630 comment 9.

Does Data Binding depend upon SWT?

No. Data Binding is meant to be UI toolkit agnostic and more specifically UI agnostic. There is default support for SWT and JFace but this is in the org.eclipse.jface.databinding project which is separate from the core Data Binding APIs that live in org.eclipse.core.databinding. For background and when the separation occurred in see bug 153630.

How do I report a bug?

On the Eclipse bugzilla log a bug to Eclipse > Platform > UI with "[DataBinding]" in the summary.

When will the public API be ready?

By 3.3M4 all API refactoring should have occurred and the code can be thought of as 1.0. (Technically, it will be version 1.1, because version 1.0 of data binding shipped with Eclipse 3.2.) But we're going to give ourselves until 3.3M5 in case any issues are found. To view the plan item for this see bug 154132.

Where can I ask a question?

You can ask questions on the Eclipse Platform newsgroup. When you post please prefix the title with "[DataBinding]".

How do I bind to the ValidationError of a Binding or DataBindingContext?

See snippet 004.

How do I run the tests?

In order to run the tests you need to check out the following projects:

  • org.eclipse.core.databinding
  • org.eclipse.core.databinding.beans
  • org.eclipse.jface.databinding
  • org.eclipse.jface.examples.databinding
  • org.eclipse.jface.tests.databinding

View the run configurations in your workspace (Run->Run...). Run JUnit Plug-in Test->JFace-Data Binding Test Suite.

Where can I get the plugins?

The JFace Data Binding plug-ins can be found in any of the following distributions on the Eclipse download page:

  • Eclipse SDK
  • RCP Runtime/SDK
  • Platform Runtime/SDK

Just select the desired build (e.g. stable, integration, nightly) and download one of the above distributions.

Where can I find examples of how to use data binding?

The org.eclipse.jface.examples.databinding project contains snippets that demonstrate some of the more common usages of the API.
