Hi!

Thanks for the report. Could you please describe how important is this feature for you?

It's not urgent but currently we had to write a workaround using the scrollChanged event which is shared by all sources of scrolling. We wanted to alter the behavior of right joystick only to add scroll acceleration. At this point we don't see an easy way to do that.

@sfernandez, I wonder if doing the same as the ScrollViewer is doing would be a better workaround? How are Scroll and HScroll events being propagated to controls?

Scroll and HScroll functions are generating MouseWheel events. ScrollViewer overrides the MouseWheel event to scroll.
The good thing about Scroll/HScroll is that it uses a float as scroll increment so you can specify the speed of the scrolling.

Wouldn't it be a better workaround overriding the MouseWheel even then?

I tried the MouseWheel event but it seem not be triggered by the scrollViewer when I used the right joystick

Is it possible that your integration layer is not sending the Scroll/ScrollH events to the IView when the right thumbstick is moved?

then I guess the scroll wouldn't work at all for the right joystick... Here is how integrated with the IView:

void SetupDisplay(NoesisApp::Display* display, NoesisApp::RenderContext* ctx, Noesis::Ptr<Noesis::IView> view)
      {
        // Gather window events and send to view
        display->SizeChanged() += [view, ctx](NoesisApp::Display*, uint32_t width, uint32_t height) {
          view->SetSize(width, height);
          ctx->Resize();
        };

        display->Activated() += [view](NoesisApp::Display*) {
          view->Activate();
        };

        display->Deactivated() += [view](NoesisApp::Display*) {
          view->Deactivate();
        };

        display->MouseButtonUp() += [view](NoesisApp::Display*, int x, int y, Noesis::MouseButton b) {
          view->MouseButtonUp(x, y, b);
        };

        display->MouseButtonDown() += [view](NoesisApp::Display*, int x, int y, Noesis::MouseButton b) {
          view->MouseButtonDown(x, y, b);
        };

        display->MouseMove() += [view](NoesisApp::Display*, int x, int y) {
          view->MouseMove(x, y);
        };

        display->MouseDoubleClick() += [view](NoesisApp::Display*, int x, int y, Noesis::MouseButton b) {
          view->MouseDoubleClick(x, y, b);
        };

        display->MouseWheel() += [view](NoesisApp::Display*, int x, int y, int delta) {
          view->MouseWheel(x, y, delta);
        };

        display->Scroll() += [view](NoesisApp::Display*, float delta) {
          view->Scroll(delta);
        };

        display->HScroll() += [view](NoesisApp::Display*, float delta) {
          view->HScroll(delta);
        };

        display->TouchUp() += [view](NoesisApp::Display*, int x, int y, uint64_t id) {
          view->TouchUp(x, y, id);
        };

        display->TouchDown() += [view](NoesisApp::Display*, int x, int y, uint64_t id) {
          view->TouchDown(x, y, id);
        };

        display->TouchMove() += [view](NoesisApp::Display*, int x, int y, uint64_t id) {
          view->TouchMove(x, y, id);
        };

        display->KeyDown() += [view](NoesisApp::Display*, Noesis::Key key) {
          view->KeyDown(key);
        };

        display->KeyUp() += [view](NoesisApp::Display*, Noesis::Key key) {
          view->KeyUp(key);
        };

        display->Char() += [view](NoesisApp::Display*, uint32_t c) {
          view->Char(c);
        };
      }
