Hello,
In order to use eclipse as a WYSIWYG application, I have to modify the Page
Designer's drag and drop feature to allow users to place elements from the
palette in the sheat with absolute positioning.
The element must been seen at its right position in editor's view and not
only in preview (like frontPage for exemple).
So I have to modify two classes in the Page Designer Plugin :
org.eclipse.jst.pagedesigner.commands.moveNodeCommand
org.eclipse.jst.pagedesigner.editpolicies.DragMoveEditPolicy
My question is : how do I do to create my own plugin which integrate these
two classes ?
Regards,
Al Rivs.

Hi Al,
The answer depends on what your change is doing. If it is an improvement
to the editor that is applicable to all users, then we may be able to
integrate it directly into the codebase if you can contribute it.
Otherwise, you have several options. One option would be to create a
plugin that installs its own IElementEditFactory for all tags. From there
you should be able change what DragMoveEditPolicy is installed on all
ElementEditParts.
Another option that might work, although I don't know much about it, would
be to use either the Fragment or Feature Patch. These allow you to modify
existing components at class load time. I'm not sure of the specifics and
I'm not certain if it allows you to affect the existing classes being
loaded or just add new ones.
Of course, last but not least would be to the import source project for
org.eclipse.jst.jsf.pagedesigner and rebuild and repackage the plugin
yourself. There is an export plugin wizard in PDE to help with this.
