24.17  text:1-pixel-tab-snip%

Superclass: tab-snip%

This class re-uses the implementation of tab-snip% to implement a string snip that is always one pixel high.

See also text:1-pixel-string-snip% for a similar extension to the string-snip%class.

This snip is used in conjunction with the frame:delegate<%> and text:delegate<%> interfaces.

• (make-object text:1-pixel-tab-snip% allocsize s) -> text:1-pixel-tab-snip% object
     allocsize = 0 : exact non-negative integer
     s : string

  Creates a snip for a single tab, though the tab is initially empty.

  Normally, a single tab is inserted into a tab-snip% object using the insert method.

  The tab's content is not drawn, through it is used when determining the size of a single character in editors where tabbing is determined by the character width (see set-tabs); if the content is a single tab character (the normal case), then the average character width of snip's font is used as the tab's width.
