Question

I try to convert a div tag into something I can drag and drop in CKEditor (as asked in another question).

Do you know how I can trigger the event when someone switches between source view and WYSIWYG mode?

I think this is what you are looking for:

CKEDITOR.on('instanceCreated', function(e) {
    e.editor.on('mode', function(e){
        // Do your stuff here
        alert(e.editor.mode);
    });
});
