set-tabs

Sets the tabbing array for the buffer.

Setting tabs is disallowed when the buffer is internally locked for reflowing (see also Locks).

• (send a-wx:media-edit set-tabs tabs tab-width in-units?) -> void
      tabs : list of inexact reals
      tab-width = wx:const-tab-width : inexact real
      in-units? = #t : boolean

  The tabs list determines the tabbing array. The tabbing array specifies the x-locations where each tab occurs. Tabs beyond the last specified tab are separated by a fixed amount tab-width. If in-units? is not #f, then tabs are specified in canvas units; otherwise, they are specified as a number of spaces. (If tabs are specified in spaces, then the graphic tab positions will change with the font used for the tab.)
