forcing Resource to be dirty [message #207918]

Hi there,

when adding/changing/deleting a Breakpoint I have to make sure the
underlying resource is saved.

My idea was to somehow set the "dirty" flag of the resource. I thought of
different approaches:
1) try to set the dirty flag directly
2) try to fire a ResourceChangeEvent
3) call the resource.touch() method

I already tried 3), which is not working :(

Concerning 1) and 2) I couldn't find out how to do this.

Any suggestions?

Thanx,
Tobias

Can you explain your problem a little more?

What do you mean by "ensuring the resource is saved"?

The contents of a resource (IFile) are stored independantly of its
markers (breakpoints).

Thanks.

Ok, let me see how to get this straight.

I have to save specific markers of a resource in a separated file. I do
this in the save-Method of the resource.
So I have to find a way to somehow "inform" the platform that the resource
has changed when a new marker of this specific type is added (or changed
or deleted).
Speaking in GUI terms: every time I add a specific marker I want the
save-Button to become active and have the small star beside it...

Thanx again,
Tobias

When you call IResource.createMarker the marker is created, the platform
stores it in a file in the metadata area (eventually when changes are
flushed), and the platform notifies listeners that this resource has
changed.

So if you register a resource change listener and listen for marker
changes on that resource you will be able to pick up the notification.

That's the Core answer but its sounding more like a question about
creating editors for your resource and displaying markers so I leave you
in the capable hands of someone with UI experience....

Markers do not have a dirty/save/clean lifecycle. They do not need to
be saved after they are created. Just create the markers and don't mark
the editor as dirty.
