Application¶

Everything in eclipse is handled through the plug-in extension mechanism, and defining an application is no different. The org.eclipse.core.runtime plug-in defines the concept of what it means to be an Application.

• Switch to the Extensions tab.

  

• Press the Add button, and select the org.eclipse.core.runtime.applications extension point.

  

• Press the Finish button.

  Hint

  You can check what xml is being generated at any point by looking at the plugin.xml tab.

• Right click on the (application) element and select New ‣ Run

  

• In the class text field enter: net.refractions.udig.tutorials.customapp.CustomApp

  

• Save your work, and then press the class link.

• Eclipse will open up a wizard for creating a New Java Class. Enter the following:

  Superclass: net.refractions.udig.internal.ui.UDIGApplication

  

• Press the Finish Button

• In the newly created file add the following method:

  @Override
  
  protected WorkbenchAdvisor createWorkbenchAdvisor() {
     return new UDIGWorkbenchAdvisor() {
        @Override
        public String getInitialWindowPerspectiveId() {
           return "net.refractions.udig.tutorials.customapp.perspective";
        }
     };
  }
  

• If you just cut and paste the above code you will be left with several problems (as UDIGWorkbenchAdvisor is not imported yet).

  Here are two ways to fix this:

  • Type CTRL + SHIFT + o

    This keyboard short cut will try and fix as many import statements as it can. Save the file after this change and the correct import statements should be there.

  • Or you can just type them in at the top of the file:

  import net.refractions.udig.internal.ui.UDIGWorkbenchAdvisor;
  

• Save your work and lets move on.
