Use of Routing and JumpLinks For Connectors [message #158477]

Hi,

By default the Routing Style of a Connector is set to Oblique.How can I
change the default value to Rectilinear.Similarly Jump Links Status is
None by default how can I change it All and Jump Type to Chamfered.

I tried to override refereshRoutingStyle() in ConnectorEditPart,but it is
throwing an Exception.Please guide me where to change and which method to
change.

Instead of overriding the code can I change something in gmfgraph or
gmfgen to do the above mentioned changes.

Thanks in advance.

Regards,
Shwetha

Dear All

We are also stuck with a similar Problem .. Can anyone help us out .. Can
anyone tell us how to configure the Style Values through GmfGraph or
GmfGen Models. If not using the model where should the code be changed.

Any help in this direction would be highly appreciated.

regards
Malai

Hello,

I managed to find the solution for my query.

To change the style property of the connector I overrided
initializeFromPreferences() in ConnectorViewFactory class generated by GMF
inside factories package.

@Override
protected void initializeFromPreferences(View view) {
super.initializeFromPreferences(view);

IPreferenceStore store = (IPreferenceStore) getPreferencesHint()
.getPreferenceStore();

RoutingStyle routingStyle =
(RoutingStyle)view.getStyle(NotationPackage.Literals.ROUTING _STYLE);
if (routingStyle != null) {
// Routing.get(1) is for RECTILINEAR Routing style.
Routing routing = Routing.get(1);
if (routing != null) {
routingStyle.setRouting(routing);
routingStyle.setJumpLinkStatus(JumpLinkStatus.ALL_LITERAL);
routingStyle.setJumpLinkType(JumpLinkType.CHAMFERED_LITERAL) ;
}
}
}

It works for me,but would be happy to know is this the right place.

Thanks and Regards,
Shwetha

Hello,

you can also change to the following code:

public class DiagramPreferenceInitializer extends
AbstractPreferenceInitializer {

/**
* @generated NOT
*/
public void initializeDefaultPreferences() {
IPreferenceStore store = getPreferenceStore();

DiagramPrintingPreferencePage.initDefaults(store);
DiagramGeneralPreferencePage.initDefaults(store);
DiagramAppearancePreferencePage.initDefaults(store);
DiagramConnectionsPreferencePage.initDefaults(store);
DiagramRulersAndGridPreferencePage.initDefaults(store);

// store.setDefault(IPreferenceConstants.PREF_LINE_STYLE,
// Routing.RECTILINEAR);
// store.setValue(IPreferenceConstants.PREF_LINE_STYLE,
// Routing.RECTILINEAR);
// store.setDefault(IPreferenceConstants.PREF_SHOW_CONNECTION_H ANDLES,
// false);

}

Hope this helps,
Johan
