Add java element decoration to a common navigator [message #641380]

Thu, 25 November 2010 04:17

Eclipse User

Hello,

I have created a common navigator to display resources (Projects, Folders, Files) on my own arrangement, with customized label and content providers.

Nevertheless, I would like to subscribe to marker service on resources when error are encountered (an error decorator is added on Java file, folder and project image when error occurs on a java class file).

Is there a way to use jdt processing or must I develop this part?

Thanks for any help

Alain

Why do you create your own common navigator?

If you really create your own common navigator then you also have to
provide the label provider to Java projects yourself. You can start by
looking at org.eclipse.jdt.internal.ui.navigator.JavaNavigatorLabelProv ider.

To elaborate on Dani's question about why are you creating your own CommonNavigator:

1) Could you use the ProjectExplorer (which has all of the resource stuff built into it)? This is simply using the org.eclipse.ui.navigator.resources plugin.

2) If you don't like some of the things the ProjectExplorer does, then you can override the navigator content extensions and provide your own label providers (including the use of the JDT's label provider as Dani mentions.

Thank you for your attention

I want to have in a wink an overview of specific resources of a project. The organization will not follow the folder hierarchy: e.g. as children of an XML file i want the generated java classes depending on the XML file.
Moreover, specific images must be associated to xml files and following to rules, decorators must be added.

I reached my objectives by this way:
Project, Folder and File classes were extended.
PackageExplorerLabelProvider was extended and getImage method was overriden.
A common navigator was created to fit the new organization.

However, it remains one last problem.
When an error occurred on a java file, an error decorator is added to the image and to all the parent folders up to the project.
I would like the image of the XML file associated to the java class to be decorated and all the parent folders the file.
Do you know a way to obtain that.

This is the problem decoration stuff which is a separate mechanism. Unfortunately I don't understand it much at all. I suggest you make a new post with "Problem decorators" in the subject and you might attract the attention of someone who can help.

Hi Alain,

I'm sorry, but I can't help you with your decoration problem..

However I have the same problem you already solved..
Could you please explain me what do you mean by "Project, Folder and File classes were extended" and how you overrode the getImage method?

Thanks

Hi,

Quote:

I created classes which extends org.eclipse.core.internal.resources.Project, org.eclipse.core.internal.resources.File, ...

Quote:

I created my own MenuNavigator which use a specific MenuLabelProvider which is inspired by org.eclipse.jdt.internal.ui.navigator.JavaNavigatorLabelProv ider.
The label provider has a field

DelegateLabelProvider delegeteLabelProvider

which refers to a class which extends org.eclipse.jdt.internal.ui.packageview.PackageExplorerLabel Provider.

Hope it helps you
