I am wondering how to customize to QCCompositionParameterView to
Quartz Composer Style: after open a Quartz Composer Composition in
Quartz Composer, we can click the parameter button to expose all
parameters in a "semi-transparent glass-like" sheet attaching to the
Viewer window.
Then how can we make the appearance of QCCompositionParameterView
like that? If it is related to any private API, I apologize.
Sheet Programming Topics for Cocoa covers sheets, so I assume you are
wondering about the transparency.
Have you tried using QCCompositionParameterView's setBackgroundColor
or setDrawsBackground methods? I don't know if they'll work, but I'd
try those first.
If all else fails, QCTV sample code creates a parameters editor
without using QCCompositionParameterView. You could adapt that code to
your needs.
