- window-bordered? windowprocedure
- set! (window-bordered? window) borderedsetter
- window-bordered-set! window borderedsetter
Get or set whether the window has a border (window decoration). #t means the window has a border, #f means the window is borderless.
Setting this to #f has essentially the same effect as passing the 'borderless flag to create-window! when creating the window.
