Is it possible to send mouse event in a remote unity window containing a noesisView ?

Yes, the architecture allows that. You can inject events manually to the view. You just need to implement the part that collects the input from the network.

I inject my position and click on MouseButtonDown but I have some issues on refreshing , sometimes events don't refresh. I don't know why currently

Does it happen if you remove the network layer and inject the events locally?

In local , the events are ok , but in remote renderer doesn't work , I modified the NoesisView file and created remote function

Well, without more information I am no able to help you. Anyway, I don't see necessary to modify NoesisView at all, you should be able to inject events from outside.

I do it because , I don't want to add code managment into xaml.cs. I build a ddl of my unity scene the only way to send event for me it's attach my objectSender into NoesisView and catch event a send to process with UpdateMouse function by example. I do this because I can't integrate noesis with my implementation but the issue it's the same.

In remote mode , the _uiView.MouseButtonDown return false , I don't know why currently

In remote mode , the _uiView.MouseButtonDown return false , I don't know why currently

That function returns false whenever the event is not being handled, so for example, when clicking in an empty area.

Do I assign the correct window to handle events ?
