I would like to use multiple-page editor (eclipse RCP). I want to follow this tutorial but I开发者_JAVA百科 cannot get "plug-in with multiple page editor" when I create a new project. I have only : Hello with a view with an introduction mail template

Does anyone have an idea about how to get the option plug-in with multiple page editor when creating a new RCP project? Thnx

PS: I use Galileo 3.5.2

Please use the Eclipse Indigo instead.

Otherwise, you can create from the empty plugin project.

Here is my example of multiple pages editor. PropertyFileEditor is multiple pages editor. Hope this will help you.

I cannot tell you, if this template is available in Galileo. It is in Indigo.

But this template just combines two steps you can do on your own. Create an empty plugin project, open the MANIFEST.MF to open the plugin editor and select the extension tabs.

There you can add extension for editors and for wizards.

For a multipage editor click on Add, then select org.eclipse.ui.editors. In the template area at the bottom of the dialog select Multi-Page editor. Then enter the properties as show in your tutorial.

Repeat for the new wizard by selectin org.eclipse.ui.newWizard and the New File Wizard template.
