Change Background Color of vsgQt::Window in QT Example

[blacktorch]

How do I change the background color from the default color in the rocky qt example.
I have tried various approaches but it does not work.

rocky_window->windowAdapter->clearColor() = VkClearColorValue{ 0.0f, 0.0f, 0.0f, 1.0f };
app.displayManager->getCommandGraph(rocky_window->windowAdapter)->window->clearColor() = VkClearColorValue{ 0.0f, 0.0f, 0.0f, 1.0f };

but the color never changes.

It's a bit overly complicated :) You have to find a vsg::View and set the clear values on its RenderGraph.
In the demo, after the call to app.displayManager->addWindow, do this:

    auto view = app.displayManager->windowsAndViews[rocky_window->windowAdapter].front();
    app.displayManager->getRenderGraph(view)->setClearValues({ VkClearColorValue{ 0.0f, 0.0f, 0.0f, 1.0f } });

Thank you so much, that worked.
