refresh all subCannonicalEditPolicies [message #104857]

Hi,

My each operation executes my MainCanonicalEditPolicy.refresh() in order
to refresh all diagram elements.

But some main diagram elements can have another one inside them.
So there is also SubCanonicalEditPolicy for them.

Unfortunatelly refreshing MainCEP does not refresh all SubCEPs.
How should I do that?

Thanks
Wiktor

CanonicalEditPolicy has some static methods to reach all policies for a
given semantic element. To see how it's done take a look in
ToggleCanonical...Command (I don't remember the exact name).

My diagram looks like this:

--MYTOP---------------------
|
| -MYCONTAINER-----
| | |
| | A |
| |_______________|
|
| MYNONCONTAINER
|
| -MYCONTAINER-----
| | |
| | B |
| |_______________|
|
----------------------------------

There can be arrows betwean containers/noncontainers
and betwean containers and their elements.

After each EMF operation on diagram command stack (i do not use GMF
operations) and/or after each change of my layer (level of visible
diagram details) i execute sth. like this:

MYTOPCanonicalEditPolicy editPolicy = (MYTOPCanonicalEditPolicy)
MYTOPCanonicalEditPolicy.getRegisteredEditPolicies(getDiagra m().getElement()).get(0);

editPolicy.refreshActiveElements();
- prepares list of visible elements and its connection (calculations
are rather complex)

editPolicy.refreshComplexEditPolicies();
- executes editPolicy1.refresh() for every MYCONTAINERS canonical edit
policy

editPolicy.refresh();
- refresh elements in MYTOP

editPolicy.refreshComplexEditPolicies();
- executes editPolicy1.refresh() for every MYCONTAINERS canonical edit
policy

but it does not work well. very often (but not always), after this whole
refresh there are less arrows on diagram than should be (but they are in
semantic model).

I suppose, that when some elements are created, another (necessary for
connections) or have been ot created yet.

I think that there should be one mechanism for refreshing all elements
on diagram - but where? maybe should I modify generated
MYTOPCannonicalEditPolicy?

I am fighting with this problem for days, with no result:(

You need to refresh when the edit part ends activate, so override these
two methods in you editparts, substituting your canonical refresh
accordingly.

vlad

public void activate() {
super.activate();
B2CanonicalConnectionEditPolicy.refresh(this);
}

public void refresh() {
if (isRefresh == false) {
isRefresh = true;
try {
super.refresh();
} finally {
isRefresh = false;
}
}

}

Many thanks for your help, but I still do not understand what should I do.

1. which editParts should I extend (all, or only few of them)?

I have such a structure:(EP=EditPart, CEP=CannonicalEditPolicy)

myNetEP - (with corresponding myNetCEP)
|
|-myNodePlaceEP
|
|-myNodeTransitionEP (with corresponding myTransitionCEP)
| |-mySubNodePlaceEP
|
|-myConnectionArrowEP

2. what should B2CanonicalConnectionEditPolicy.refresh(this); do?
I suppose that B2CCEP is myNetCEP - also extends CCEP.

3. To be sure - isRefresh should be a private variable of my EP's (not
global from for e.g. NetCEP)?

I'll attach the files for you in an email.

You should extend the editparts that can be created programmatically,
together with the connection.

Thanks, but my problem seems to be more global . for a moment I forgot
even about my 'parts in parts', and I try to solve my bug on 'flat
structure'. I do not know why

standard CanonicalConnectionEditPolicy cannot find in

protected final Edge createConnectionView(EObject connection, int index) {
EditPart sep = getSourceEditPartFor(connection);
EditPart tep = getTargetEditPartFor(connection);

sep or tep (usually for elements which should exists). Sometimes I have
here null, so new/old connections are not created.

any ideas?
