Open a file [message #714225]

How do I open (in a plugin) an external file in Eclipse, but not in a projekt ? ... so just an editor-window.

It must be possible, because when I open a file via menu "File", "Open file ..." it opens the file outside a projekt in an editorwindow, and my plugin (with reserved words and stuff) does it's thing.

See org.eclipse.ui.ide.IDE.openEditorOnFileStore(IWorkbenchPage,
IFileStore).

Hi Dani,

Thanks for your reply. Doing it with "openEditorOnFileStore" only works if the file-extension is by default opened with Eclipse (f.e. when you double-click in the Windows file Explorer). For files that are by default opened f.e. with Notepad it doesn't work ... whereas when I open these files via menu "Open - Open file ..." the file (off course) is opened by Eclipse.

Do you have any idea how menu "Open - Open file ..." does it ?

Yes, it calls the method I gave you. I guess when you tested in your
workspace, you had an association defined in Eclipse.

Nope, the association is not to Eclipse.
But I got it working with a method of the same class :
IDE.openEditor( page, lcUri, lcEditorId, true );

Thanks for your help. By the way, do you know how to prevent this :

when I remove (via my plugin, but also when I do it manually) the last file from a project the project visually still has one empty "something" open. I see a small dotted line in the project. When I unfold the project, it's gone. Is this something I could prevent in my plugin when I remove the last files ?

Well, you can File > Open File on some file type not known by Eclipse
and it will open it with the OS editor.

I've never seen that.

There is a difference between files opened inside / outside a project.
I have made a new editor which is attached to file-extension ABC.

When I open an ABC-file inside a project, I can get its full filename with below code :

private IEditorPart prvEditor;
private IEditorInput prvEditorInput;
private IFileEditorInput prvFEI;
private IFile prvFile;
private String prvFullFileName;

prvEditor = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor();
prvEditorInput = prvEditor.getEditorInput();
prvFEI = (IFileEditorInput) prvEditorInput;
prvFile = prvFEI.getFile();
prvFullFileName = prvFile.getLocation().toOSString();

When I open an ABC-file outside a project, I can't get its full filename with above code, it goes into catch on statement "prvFEI = (IFileEditorInput) prvEditorInput;"

How to make above code working for a file which is opened outside a project?
