Create Application model depending on login information [message #23776] Mon, 30 March 2009 07:44 Go to next message

Hi,

I want to create my application model depending on the current users
permissions.

The problem is that IApplicationNode.createModel() is called before login
has been performed.

Is there any possibility to manipulate the displayed model nodes after
login? Or is there any out of the box solution for this?

Thanks and greetz,
Carsten

Hi Carsten,

you are right in case you use the splash login view (its different for
the login dialog view). The splash login view is brought up when the
workbench is created and that is after createModel() was called. I think
you can use the riena ui filters (see
http://wiki.eclipse.org/Riena_UI_filters) to manipulate the displayed
model nodes based on permissions. Override the createView() method of
your application class (subclass of SwtApplication) like this:

@Override
public Object createView(IApplicationContext context, IApplicationNode
pNode) {
Collection<IUIFilterRule> rules = new ArrayList<IUIFilterRule>(1);

// hidden marker for all children of application node
IUIFilterRule filterRule = new UIFilterRuleNavigationHiddenMarker("/"
+ pNode.getNodeId().getTypeId() + "/*") {
@Override
public boolean matches(Object... args) {
return super.matches(args) && !getPermission(args);
}

private boolean getPermission(Object... args) {
boolean permission = true;
if (args[0] instanceof INavigationNode<?>) {
permission = // get permission for node (args[0])
}

return permission;
}
};
rules.add(filterRule);
IUIFilter filter = new UIFilter(rules);
pNode.addFilter(filter);

return super.createView(context, pNode);
}

Also there is an API method setVisible() in INavigationNode to set the
visibility of a node.

Regards, Frank

Hi Frank,

thanks for your reply!

I tried the way you explained via the UIFilter. Unfortunately I have two
problems with this solution:

1) The class UIFilterRuleNavigationHiddenMarker seems to be internal.
2) The UI shows a bad looking gray "placeholder" where the now hidden
navigation node was displayed before until I "click" somewhere in the UI
(maybe this is only a refresh problem?)

Greetz,
Carsten

Hi Carsten,

you are right class UIFilterRuleNavigationHiddenMarker is internal and
so should be used only with caution, because this code may undergo
changes. May be you file a bugzilla request which describes your problem
and mentions that class UIFilterRuleNavigationHiddenMarker is internal.
The gray "placeholder" seems to be a refresh problem. Can you file
bugzilla request for that? Is it a submodule your are hiding?

Regards, Frank

Collection<IUIFilterRule> rules = new ArrayList<IUIFilterRule>(1);

// hidden marker for all children of application node
IUIFilterRule filterRule = new UIFilterRuleNavigationHiddenMarker("/"
+ pNode.getNodeId().getTypeId() + "/*") {
@Override
public boolean matches(Object... args) {
return super.matches(args) && !getPermission(args);
}

private boolean getPermission(Object... args) {
boolean permission = true;
if (args[0] instanceof INavigationNode<?>) {
permission = // get permission for node (args[0])
}

return permission;
}
};
rules.add(filterRule);
IUIFilter filter = new UIFilter(rules);
pNode.addFilter(filter);

return super.createView(context, pNode);
}

Also there is an API method setVisible() in INavigationNode to set the
visibility of a node.
