In this case, the sender is on a small view.
On small view -> root -> onClicked event -> sendMessage
This small view, is instantiated on a large view.
On large view -> root -> script -> message handler listening.
How do I properly set the 'minimal' scope, for communication to take place?
Hey Eugene49, for the minimal scope you will need to specify the scope in the small view when you do system.perspective.sendMessage.
In the scope parameter, you can define the scope to be "view" in order for your execution to take place.
We also have an example of component message handlers listed in our User Manual as well.
So I made a cheat sheet below, who's sending to where and who's listening from where.
Sender and receiver can only communicate according to scope setting strictly.
I like that diagram, but it there are some additional aspects it doesn't cover or illustrate well.
When a message is sent ("broadcast" for the rest of this post), you specify a singular scope. This specified scope determines how broadly the message will be broadcast, whether it be limited to only this View, this Page, or all Pages (browser tabs) in this Session.
When a handler/listener is configured to listen for broadcast messages, the listener can actually have multiple scopes.
Suppose I create a message (named
DEMO) to be broadcast at the
view scope on
DemoViewA. I also create a second message with the same name to be broadcast with a
session scope inside of
DemoViewA I create a handler/listener with a name of
DEMO which will listen at both the
I make two pages --
PageB -- where
DemoViewA somewhere within its content, and
DemoViewB somewhere within its content. I create a session which contains two tabs; one open to
PageA and one open to
If I trigger some action on
PageB which would broadcast my message, then the listener/handler within
PageA will "hear" the broadcast message because that other page is listening for the
DEMO message at both the
You mean the feature where the listener can listen to multiple scope, right?
I didn't intend the diagram to be complete, but shows basicly how the communicate.
Nice to have multiple Listen scope.
