semi transparency?

Hello,

i need to create a semi-transparent dark overlay (window, canvas etc.) where the underlying controls are visible through that, like opacity 80% of black.
Is that possible with xojo (on Windows), with or without plugins?

Some old test re-purposed code until I get around to doing actual control transparency
