There are three CSS examples available.

CSS'ified RCP Mail Application

This is the RCP mail app example, with CSS goodness added. Also acts as an example of how to add CSS to your application.
Features:

• Entirely styled with a CSS stylesheet.
• Notice the date is in italics, this is to indicate that the message is unread. Clicking on the mail icon in the toolbar will mark the message as read, and the italics will go away. This demonstrates use of changing the CSS class name of an element to switch which style it uses:

.messageDateUnRead {
    font-style: italic;
}

.messageDateRead {
    font-style: normal;
}

CSS Live Editors

There are two examples that show a number of widgets styled with a stylesheet, with an editor area where you can modify the stylesheet. Changes in the stylesheet are immediately reflected in the widgets.

CSS SWT Editor

This provides a number of SWT widgets being styled.

CSS Nebula Example

We have CSS support for styling the Nebula Gallery widget (as seen in the e4 photo demo). This little example is like the SWT editor above, but for styling the Gallery widget.

Getting the Examples

After installing e4 UI, check out the e4 css example projects from CVS as follows:

1. Start Eclipse with an empty workspace directory.
2. Select File > Import... and select CVS > Projects from CVS, click Next.
3. Copy the CVS repository location and paste it into the "Host" field to populate the wizard page: :pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse
4. You should see "Host: dev.eclipse.org, Repository path: /cvsroot/eclipse, User: anonymous, Connection type: pserver".
5. Click Next and select the second option Use an existing module.
6. Drill down as follows: e4 > org.eclipse.e4.ui > examples and select three projects:
   1. org.eclipse.e4.ui.examples.css
   2. org.eclipse.e4.ui.examples.css.nebula
   3. org.eclipse.e4.ui.examples.css.rcp.
7. Click Finish.
8. This will check out the three projects into your workspace.
