Summary

Tag name: <tr:inputColor>
UIComponent class: org.apache.myfaces.trinidad.component.core.input.CoreInputColor
Component type: org.apache.myfaces.trinidad.CoreInputColor
The inputColor component creates a text field for entering colors. Users can specify color values in one of three ways, depending on how the inputColor component is configured.

  • Users can type the color value directly in the field. This option is always available.
  • Users can select a color value from a secondary dialog. This option may not be available in all look and feel implementations. In particular, this option is not available on PDA look and feels.
  • Users can select a color value from an inline chooseColor component. In order to enable this option, the chooseColor must be placed in the same page as the inputColor, and the inputColor's paletteId attribute must be set to the id of the corresponding chooseColor. Again, this option is not supported on PDA look and feel.

The colorConverter can be used to control both the formatting that the inputColor uses when displaying color values, as well as the set of color format patterns that are accepted by the inputColor. See the documentation for the colorConverter for more information.

Code Example(s)

<tr:inputColor name="color" value="#{color.colorValue3}" />

Events

Type Phases Description
javax.faces.event.ActionEventApply Request ValuesEvent delivered when the "action" of the component has been invoked; for example, by clicking on a button. The action may result in page navigation.
org.apache.myfaces.trinidad.event.ReturnEventApply Request ValuesEvent delivered when the dialog has completed successfully.
javax.faces.event.ValueChangeEventProcess Validations,
Apply Request Values
The valueChange event is delivered when the value attribute is changed.
org.apache.myfaces.trinidad.event.AttributeChangeEventInvoke 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.

Supported Facets

Name Description
helpThis facet should contain field level help.

Attributes

Name Type Supports EL? Description
accessKeycharYes Character used to gain quick access to the form element specified by the for, if set (or this component itself, if it is a "non-simple" form element). For accessibility reasons, this functionality is not supported in screen reader mode. If the same access key appears in multiple locations in the same page of output, the rendering user agent will cycle among the elements accessed by the similar keys.

This attribute is sometimes referred to as the "mnemonic".

actionjavax.el.MethodExpressionYes a reference to an action method sent by the commandButton, or the static outcome of an action
actionListenerjavax.faces.el.MethodBindingOnly EL a method reference to an action listener
attributeChangeListenerjavax.el.MethodExpressionOnly 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.
autoCompleteStringYes Valid Values: on, off
Default Value: on

whether previous values of text fields in the form should be remembered and offered for auto completion.
autoSubmitbooleanYes Default Value: false

If set to TRUE on a form element, the component will automatically submit the enclosing form when an appropriate action takes place (a click, text change, etc.).
bindingorg.apache.myfaces.trinidad.component.core.input.CoreInputColorOnly 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.
chooseIdStringYes The id of the inline chooseColor component which can be used to update the Color value for this inputColor. Use the same syntax as partialTriggers if the components are separated by Naming Containers.
columnsintYes the number of columns to display in the text control. If no value is specified, a default value will be derived from the current converter, if one is attached.
compactbooleanYes Default Value: false

If true, attempt to use less screen real-estate to display the inputColor. For example, this might cause the text area not to be rendered, and the color swatch conveys the currently selected color.
contentStyleStringYes the CSS styles to attach to the content of the component. For example, you can set the width of that portion to 100 pixels by setting this attribute to "width: 100px".
converterjavax.faces.convert.ConverterYes a converter object
disabledbooleanYes Default Value: false

whether the element is disabled.
idStringNo 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 ('-').
immediatebooleanYes Default Value: false

whether the value is converted and validated immediately in the Apply Request Values phase, or is handled in the Process Validators phase, the default. By default, values are converted and validated together in the Process Validators phase. However, if you need access to the value of a component during Apply Request Values - for example, if you need to get the value from an actionListener on an immediate commandButton - then setting this to "immediate" makes that possible.
inlineStyleStringYes the CSS styles to use for this component.
labelStringYes the label of the bean.
labelAndAccessKeyStringYes An attribute that will simultaneously set both the "value" and "accessKey" attributes from a single value, using conventional ampersand ('&') notation.

For example, setting this attribute to "L&amp;abel" will set the label to "Label" and the access key to 'a'.

onblurStringYes the event handler for the component losing the focus.
Not supported on the following agents: pda
onchangeStringYes event handler for when the value is changed.
onclickStringYes an onclick Javascript handler.
ondblclickStringYes an ondblclick Javascript handler.
onfocusStringYes the event handler for the component gaining the focus.
Not supported on the following agents: pda
onkeydownStringYes an onkeydown Javascript handler.
onkeypressStringYes an onkeypress Javascript handler.
onkeyupStringYes an onkeyup Javascript handler.
onmousedownStringYes an onmousedown Javascript handler.
onmousemoveStringYes an onmousemove Javascript handler.
onmouseoutStringYes an onmouseout Javascript handler.
onmouseoverStringYes an onmouseover Javascript handler.
onmouseupStringYes an onmouseup Javascript handler.
partialTriggersString[]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.

Separate multiple triggers with a space. e.g., partialTriggers="cmp1 cmp2"

Identifiers must account for NamingContainers. You can use a single colon to start the search from the root, or use multiple colons to move up through the NamingContainer. For example, "::" will pop out of this component's naming container (it pops out of itself if it is a naming container), ":::" will pop out of two naming containers, etc. The search for the partialTrigger begins from there. e.g., partialTriggers=":::commandButton1" the search begins for the component with id = commandButton1 after popping out of two naming containers relative to this component. To go into naming containers, you separate the naming containers with ':', e.g.,partialTriggers= "nc1:nc2:nc3:componentId".

readOnlybooleanYes Default Value: false

whether the element is read-only.
renderedbooleanYes 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.
requiredbooleanYes Default Value: false

whether a non-null, non-empty value must be entered. If false, validators will not be executed when the value is null or empty.
requiredMessageDetailStringYes the message to be displayed, if 'required' validation fails.

Parameters:

  • {0} the label that identifies the component
returnListenerjavax.el.MethodExpressionOnly EL a method reference to an return listener
shortDescStringYes The short description of the component. This text is commonly used by user agents to display tooltip help text.
showRequiredbooleanYes Default Value: false

whether the associated control displays a visual indication of required user input. If a "required" attribute is also present, both the "required" attribute and the "showRequired" attribute must be false for the visual indication not to be displayed.
simplebooleanYes Default Value: false

a boolean value that controls whether the component provides label and message support; when set to "true", the component will not display messaging support or the label (these attributes may be ignored: label, labelAndAccessKey, accessKey, showRequired, tip), and may use simpler layout primitives
styleClassStringYes a CSS style class to use for this component.
validatorjavax.faces.el.MethodBindingOnly EL a method reference to a validator method
valueObjectYes the value of the component. If the EL binding for the "value" points to a bean property with a getter but no setter, and this is an editable component, the component will be rendered in read-only mode.
valueChangeListenerjavax.faces.el.MethodBindingOnly EL a method reference to a value change listener
