Close window when file is deleted [message #301119]

Hello,

Im writing an Eclipse plugin with an MultiPageEditor. If I open a file I see
the information in my editor just fine. If I keep my file open but delete
the file from the resources view I want my editor to close automatically but
it don't. How can't I make this happen?

Many regards
Bj

Look at the way the classes in the hierarchy for TextEditor do it (I
think it's in AbstractTextEditor). Basically, you have to register an
IResourceChangeListener and close on a delete.

Create a class that implements IResourceChangeListener and pass the editor
into the constructor. So e.g.

class MyResource implements IResourceChangeListener

public MyEditor editor

public MyResource (MyEditor e) {
editor = e;
}

public void resourceChanged(IResourceChangeEvent event) {
IFile file = ((FileEditorInput)editor.getEditorInput()).getFile();
LOG.debug("event.getType()" + event.getType());
if ((event.getType() == IResourceChangeEvent.PRE_DELETE
|| event.getType() == IResourceChangeEvent.PRE_CLOSE)
&& event.getResource().equals(file.getProject())) {
closeEditor();
}
}

private void closeEditor() {
Display.getDefault().syncExec(new Runnable() {
public void run() {
editor.getSite().getPage().closeEditor(editor, false);
}
//probably remove listener here
}

Then in your MyEditor class add into the init method

listener = new MyResource(this);
ResourcesPlugin.getWorkspace().addResourceChangeListener(lis tener);

I found the code example to be somewhat incomplete. See attached file for more complete version.
