I've spent a few days trying to figure out the following. My editor is a
debugger so I need to be able to switch around between files while I'm
stepping through the code. I've succeeded in being able to switch between
files if a file is already open in an editor. However this puts a
requirement on the user to have to go open any files he is going to be
stepping through before actually stepping into them.
Additionally I'd like to be to search a project and create an editor
instance for each file that has the particular extension my editor handles.
And if you really have a thorough understanding of how the project
management portion of the eclipse plugin API works: Given a file with the
correct extension that my editor handles, being able to programatically
create a link to it in a project and then open it would really be cool to
know how to do as well.
A small snippet of code would be nice but just telling me a class, how I
instantiate that class from within a plugin class and the method I would use
to instantiate the editior is cool.. The enviroment I'm working from is a
plugin class erived from the AbstractUIPlugin class.
If you don't know how to search the project but do know how to
programatically create an instance of the editor from within a plugin class
that would be a big help just knowing how to do that.
Thanks for any help anyone can provide (I'm running out of time).

I've requested some new APIs to make this easier but here's a code snippet I
use that opens a file and goes to a line number in M6. The most important
parts are the page.openEditor() and root.getFileForLocation() methods.
/**
* Open a file in the Workbench that may or may not exist in the
workspace. Must be run on the
* UI thread.
*
* @param filename
* @param line
* @throws CoreException
*/
public static void openFile(String filename, int line) throws
CoreException {
// reject directories
if (new File(filename).isDirectory())
return;
IWorkbench workbench = PlatformUI.getWorkbench();
IWorkbenchWindow window = workbench.getActiveWorkbenchWindow();
IWorkbenchPage page = window.getActivePage();
File file = new File(filename);
// If the file exists in the workspace, open it
IEditorInput input = createEditorInput(file);
String editorId = getEditorId(file);
IEditorPart editor = page.openEditor(input, editorId);
ITextEditor textEditor = (ITextEditor)
editor.getAdapter(ITextEditor.class);
// If a line number was given, go to it
if (line > 0) {
try {
line--; // document is 0 based
IDocument document =
textEditor.getDocumentProvider().getDocument(textEditor.getE ditorInput());
textEditor.selectAndReveal(
document.getLineOffset(line),
document.getLineLength(line));
} catch (BadLocationException e) {
// invalid text position -> do nothing
}
}
}
private static String getEditorId(File file) {
IWorkbench workbench = PlatformUI.getWorkbench();
IEditorRegistry editorRegistry = workbench.getEditorRegistry();
IEditorDescriptor descriptor =
editorRegistry.getDefaultEditor(file.getName());
if (descriptor != null)
return descriptor.getId();
return "org.eclipse.ui.DefaultTextEditor"; //$NON-NLS-1$
}
private static IEditorInput createEditorInput(File file) {
IFile workspaceFile = getWorkspaceFile(file);
if (workspaceFile != null)
return new FileEditorInput(workspaceFile);
// support for external files you probably don't need: return new
ExternalFileEditorInput(file);
return null;
}
private static IFile getWorkspaceFile(File file) {
IWorkspace workspace = ResourcesPlugin.getWorkspace();
IPath location = new Path(file.getAbsolutePath());
return workspace.getRoot().getFileForLocation(location);
}
