ItemStyle

ItemStyle

is an option for Dataset, Grid and related constructs that specifies styles to use for items.

Details

  • ItemStyle->s specifies that all items should use style specification s.
  • Item style specifications can include all options to Item, as well as options to Style. Directive[opt1,opt2,…] can be used to specify multiple options.
  • Item style specifications are applied to the complete region of an item, not just its contents, so that, for example, backgrounds extend to the edge of the item.
  • The settings for ItemStyle can be given as follows to apply separately to different items:
  • specapply spec to all items
    {specx}apply specx at successive horizontal positions
    {specx,specy}apply speck at successive horizontal and vertical positions
    {spec_(x),spec_(y),rules}also allow explicit rules for individual i,j elements
  • The speck can have the following forms:
  • {s1,s2,…,sn}use s1 through sn; then use defaults
    {{c}}use c in all cases
    {{c1,c2}}alternate between c1 and c2
    {{c1,c2,…}}cycle through all ci
    {s,{c}}use s, then repeatedly use c
    {s1,{c},sn}use s1, then repeatedly use c, but use sn at the end
    {s1,s2,…,{c1,c2,…},sm,…,sn}use the first sequence of si at the beginning, then cyclically use the ci, then use the last sequence of si at the end
    {s1,s2,…,{},sm,…,sn}use the first sequence of si at the beginning and the last sequence at the end
    {i1->v1,i2->v2,…}specify what to use at positions ik
    {spec,rules}use rules to override specifications in spec
  • If multiple speci or rules specify styles for a particular element, the styles are combined in the order they appear.

Basic Examples  (3)

Style all the elements in the grid:

Style the first row:

Use a style from the current stylesheet:

Scope  (6)

Blue and red font colors for the first and second horizontal positions:

Blue and red font colors for the first and last horizontal positions:

Blue and red font colors for the first and second vertical positions:

Alternating blue and red font colors:

Alternating font colors with orange superimposed in the first and last positions:

Style specific elements:

Style a region:

Overlapping specifications are unified when possible:

Generalizations & Extensions  (1)

Color negative numbers red in Dataset:

Properties & Relations  (1)

BaseStyle can be used to specify a style for the entire grid:

Possible Issues  (2)

Column styles have precedence over row styles:

Use Directive to wrap multiple style directives:
