Summary
Tag name:
<
af:chooseColor
>
UIComponent class:
oracle.adf.view.faces.component.core.input.CoreChooseColor
Component type:
oracle.adf.CoreChooseColor
The chooseColor control creates a palette for picking colors.
A chooseColor can display two sets of colors:
-
A set of standard colors, as specified by the colorData
attribute.
-
A set of custom colors which extend the set of colors available
in the standard palette. Custom colors are specified by the
customColorData attribute.
Both the colorData and customColorData attributes accept both
List and array objects, each of which contain one java.awt.Color
instance for each color to display.
In order to simplify the use of standard palettes, ADF Faces makes
certain palettes available via the uix.colorPalette EL implicit
object. The "#{adfFacesContext.colorPalette}" implicit object
provides access to four standard color palettes:
-
"default49"
: 49 colors, including
one transparent entry.
-
"opaque49"
: 49 colors, without
a transparent entry.
-
"default80"
: 80 colors, including
one transparent entry.
-
"web216"
: the 216 "web-safe"
colors.
Example:
<!-- A chooseColor which uses the standard "default49" palette -->
<af:chooseColor id="cc0"
colorData="#{adfFacesContext.colorPalette.default49}"/>
<!-- A chooseColor which defines custom colors using inline data -->
<af:chooseColor id="cc1" colorData="#{adfFacesContext.colorPalette.default49}"
customColorData="#{myBean.listOfColors}">
<!-- A chooseColor that is associated with a selectInputColor -->
<af:selectInputColor id="sic1" chooseId="cc2"/>
<af:chooseColor id="cc2" width="18"
colorData="#{adfFacesContext.colorPalette.web216}"/>
