Note that in the above example, if we want to control the foreground color
  of the text items, we cannot issue commands such as:
  .t insert end -itemtype text -text "First Item" -foreground black
 because 
-foreground is not an individual attribute of the text
  item. Instead, it is a collective attribute and must be accessed using a
  display style object. To do that we can use the command 
tixItemStyle to create display styles, as shown in the following
  example:
  set style1 [tixDisplayStyle text -font 8x13]set style2 [tixDisplayStyle text -font 8x13bold]
tixTList .t; pack .t
.t insert end -itemtype text -text "First Item"  -underline 0 
    -style $style1.t insert end -itemtype text -text "Second Item" -underline 0  
    -style $style2.t insert end -itemtype text -text "Third Item"  -underline 0  
    -style $style1The first argument of 
tixDisplayStyle specify the type of style we
  want to create. Each type of display item needs its own type of display
  styles. Therefore, for example, we cannot create a style of type 
text and assign it to an item of type image. The subsequent
  arguments to 
tixDisplayStyle set the configuration options of the
  collective attributes defined by this style. A complete list of the
  configuration options of each type of the display style is in figures ???
  through ???.
   The 
tixDisplayStyle command returns the names of the newly created
  styles to us and we use the variables 
style1 and style2 to
  store these names. We can then assign the styles to the display items by
  using the names of the styles. As shown in figure 3-5, by
  assing these two styles to the 
-style option of the display items,
  we assigned a medium-weight font to the first and third item and a bold
  font to the second item.
  (Figure 3-5) Two Display Styles With Different Fonts    
   The name of the style returned by 
tixDisplayStyle is also the name
  of a command which we can use to control the style. For example, we can
  use the following commands to switch the fonts in the two styles we
  created in the above example:
  $style1 configure -font 8x13bold$style2 configure -font 8x13
   After the execution of the above command, the font in the second item in
  the TixTList widget becomes medium-weight and the font in the first and
  third items becomes bold, as shown in figure 3-5.
