drscheme:unit:make-bitmap in DrScheme Tools Functions

• (drscheme:unit:make-bitmap button-name) -> ((is-a?/c area-container<%>) . -> . (union string? (is-a?/c bitmap%)))
     button-name : string?

  
  

• (drscheme:unit:make-bitmap text filename-or-bitmap) -> ((is-a?/c area-container<%>) . -> . (union string? (is-a?/c bitmap%)))
     text : string?
     filename-or-bitmap : (union string? (is-a?/c bitmap%))

  This function constructs a bitmap for a button label. It is used for the buttons on the top row of DrScheme's frame.

  When one argument is supplied, this function constructs a button from the image in the icons collection named by the button-name with .bmp added to the end of the name. The button's label is also button-name, but with the first letter capitalized.

  When two arguments are supplied, constructs a button with text as the button's label and where filename-or-bitmap specifies the full path to the bitmap or an immediate bitmap.

  The area-container<%> argument is used to find the font for the label.

  If the bitmap isn't found, this function returns a string to be used as the button's label.
