Eclipse Intro / Welcome page

is it possible to have links on the welcome page which point to defined commands and for example, launch an dialog?

I am thinking of having a welcome page, pointing out the steps what to do fi开发者_JS百科rst, like:

1) change language (click here)
2) set up database connection (click here)
3) start working (click here)

"click here" should be a link to call the actual dialog to set things up. I am using Eclipse with the command style menu.

Grateful for any suggestions!

You can run jface actions from the welcome page like this (in the introContent.xml)

<link 
label="System Configuration" 
url="http://org.eclipse.ui.intro/runAction?pluginId=org.eclipse.ui.internal&#38;class=org.eclipse.ui.internal.OpenPreferencesAction">
   <img src="config.png" alt="System Configuration"/>
   <text>Current system configuration.</text>
</link>

if your intro page is in XHTML. The encoded ampersand & is quite a common pitfall. You can also call your own implemented action class (not a predefined one from org.eclipse.ui.*), but you should then implement the IIntroAction like this

public class YourPreferencesAction extends OpenPreferencesAction implements IIntroAction {

    @Override
    public void run(IIntroSite site, Properties params) {
        final IIntroPart introPart = PlatformUI.getWorkbench().getIntroManager().getIntro(); 
        PlatformUI.getWorkbench().getIntroManager().closeIntro(introPart);  
        run();
    }

}

where you close the intro page and call some method you would like to have executed, in this case run(). Your actions class should in all cases inherit from org.eclipse.jface.Action.

Take a look at the Eclipse forms API. Here's a tutorial I found very useful: http://www.eclipse.org/articles/Article-Forms/article.html

Forms can have links in them, and those links call back to HyperLinkListeners. It doesn't look like the HyperLink class is linked into the Command framework yet. Though I could be wrong about that. There are a number of things that haven't really been integrated with the Command framework yet. You could use your HyperlinkListener to call the Command's handler if you like, implementing the command calling functionality manually.

Here's the API docs for HyperLinks: http://help.eclipse.org/galileo/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/ui/forms/widgets/Hyperlink.html
