af:chooseColor chooseColor choose color

UIComponent class: oracle.adf.view.rich.component.rich.input.RichChooseColor
Component type: oracle.adf.RichChooseColor

The chooseColor component is used in conjunction with a inputColor to allow the user to quickly select a color value without having to navigate to a secondary window. The chooseColor is typically used for tasks where selecting a color value is a critical part of the task flow. Instead of requiring the user to select the color from a secondary window, a chooseColor can be displayed inline in the page contents. Users can then select a color directly within the chooseColor, which will cause the currently focused inputColor to be updated with the selected color.

In order to indicate that a particular inputColor should be updated in response to chooseColor selection changes, the inputColor's "chooseId" attribute must be set to the id of the associated chooseColor component.

Events

Type Phases Description
org.apache.myfaces.trinidad.event.AttributeChangeEvent Invoke Application,
Apply Request Values
Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.

Attributes

Name Type Supports EL? Description
attributeChangeListener javax.el.MethodExpression Only EL a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
binding oracle.adf.view.rich.component.rich.input.RichChooseColor Only EL an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
clientComponent boolean Yes Default Value: false

whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary.
colorData java.util.List Yes the list of colors to be displayed in the standard color palette. The number of provided colors can be 49, 64 and 121, depending on the width attribute. For example, if width is 7, the number should be 49. If the number does not match the width, extra color element in the list will be ignored and missing color elements will be displayed as no-color. The color list must be of an array of type TrColor in the client side. On the server side, it must be a java.util.List of java.awt.Color objects or a java.util.List of hex color code strings (in the tag only). Customer may define their own color palette, such as show 169 color palette with width of value 13.
customColorData java.util.List Yes the list of custom defined colors. The number of colors can be 7, 8, 11, equivalent to the width attribute. The color list must be of an array of type TrColor in the client side. On the server side, it must be a java.util.List of java.awt.Color objects or a java.util.List of hex color code strings (in the tag only).
customVisible boolean Yes Default Value: true

whether the Custom Color button and custom color row are displayed. When set to true, the Custom Color Button and custom color row will be rendered.
customizationId String Yes This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.
defaultColor java.awt.Color Yes the default color. When setting, using the tag it could take a type java.lang.String of #RRGGBB hex color code, e.g. #000000.
Not supported on the following renderkits: oracle.adf.core
defaultVisible boolean Yes Default Value: true

whether the Default button is displayed. When set to true, the Default Button will be rendered.
id String No the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
  • Must not be a zero-length String.
  • First character must be an ASCII letter (A-Za-z) or an underscore ('_').
  • Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an underscore ('_'), or a dash ('-').
inlineStyle String Yes the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. Be aware that because of browser CSS precedence rules, CSS rendered on a DOM element takes precedence over external stylesheets like the skin file. Therefore skins will not be able to override what you set on this attribute. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.
lastUsedVisible boolean Yes Default Value: true

whether the Last Used button is displayed. When set to true, the Last Used Button will be rendered. Last used color information does not persist across browser sessions.
partialTriggers String[] Yes the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.
rendered boolean Yes Default Value: true

whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
shortDesc String Yes the short description of the component. This text is commonly used by user agents to display tooltip help text, in which case the behavior for the tooltip is controlled by the user agent, e.g. Firefox 2 truncates long tooltips. For form components, the shortDesc is displayed in a note window. For components that support the helpTopicId attribute it is recommended that helpTopicId is used as it is more flexible and is more accessibility-compliant.
styleClass String Yes a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.
unsecure java.util.Set Yes A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute. Note that when you are able to set a property on the client, you will be allowed to by using the the .setProperty('attribute', newValue) method, but not the .setXXXAttribute(newValue) method. For example, if you have unsecure="disabled", then on the client you can use the method .setProperty('disabled', false), while the method .setDisabled(false) will not work and will provide a javascript error that setDisabled is not a function.
visible boolean Yes Default Value: true

the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property.
Not supported on the following renderkits: org.apache.myfaces.trinidad.core
width int Yes Default Value: 7

the width of the standard palette in cells. The default supported values are 7, 8 and 11 which will show the palette with 49, 64 and 121 colors respectively. If the width specified is not one of the default supported values, the color palette with closest and less number of colors will be used unless a custom color palette is defined using the colorData attribute.
