## All primitives have non-transparent backgrounds by default
|

## Setting a primitive's background color to `tcell.ColorDefault` does not result in transparency
|

|

Setting background colors to `tcell.ColorDefault` is insufficient. Call
|
||||
`SetBackgroundTransparent(true)` to enable background transparency. See
|

[#15](https://gitlab.com/tslocum/cview/-/issues/15) for more info.

Note that setting the background color of a primitive to tcell.ColorDefault is

insufficient to achieve transparency (having one or more widgets behind another

Setting the background color of a primitive to tcell.ColorDefault will use the
