### 6.58.3. Creating the Component with a Page Tag

Here is a simple example of how the component can be used on a page:

Example:

    ...

    <rich:inplaceInput value="#{bean.value}"/>

    ...

### 6.58.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.inplaceInput;

    ...

    HtmlInpaceInput myInplaceInput = new InplaceInput();

    ...

### 6.58.5. Details of Usage

The <rich:inplaceInput> component was designed to facilitate displaying and inputting(editing) some data.

The "value" attribute is a value-binding expression for the current value of the component.

The component has three functional states:

- View state displays default label with the value taken from "value" or "defaultLabel" attributes.

  If the initial value of the "value" attribute is "null" or empty string the "defaultLabel" attribute is used to define default label.

  Example:

      ...

      <rich:inplaceInput value="#{bean.value}" defaultLabel="click to edit"/>

      ...

  In the example above the "value" attribute is not initialized therefore "`click to edit`" text, that "defaultLabel" , contains is displayed.

  This is the result:

  Figure 6.137. View state

- Edit state - input representation to allow value edit

  Figure 6.138. Edit state

- Changed state - value representation after it was changed

  Figure 6.139. Changed state

The "editEvent" attribute provides an option to assign a JavaScript action to initiate the change of the state from view/changed to edit. The default value is "onclick".

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" editEvent="ondblclick"/>

    ...

The <rich:inplaceInput> component provides specific event attributes:

- "oneditactivation" which is fired on edit state activation

- "oneditactivated" which is fired when edit state is activated

- "onviewactivation" which is fired on view state activation

- "onviewactivated" which is fired after the component is changed to representation state

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" oneditactivation="if (!confirm('Are you sure you want to change the value?')){return false;}" />

    ...

The given code illustrates how "oneditactivation" attribute works, namely when the state is being changed from view to edit, a confirmation window with a message `"Are you sure you want to change value?"` comes up.

Using the boolean "selectOnEdit" attribute set to true, the text in the input field will be selected when the change from view/changed state to edit occurs.

This is the result:

Figure 6.140. Usage of the "selectOnEdit" attribute

If the <rich:inplaceInput> loses focus, input data is saved automatically and the component displays a new value. Additionally, the data is saved when "Enter" is pressed. Nevertheless, you can use the "showControls" attribute, which makes "Save" and "Cancel" buttons appear next to the input field. If the controls are used, data is not saved automatically when the form loses focus: user has to confirm that he/she wants to save/discard the data explicitly. In both cases(with controls or without them) the input data can be discarded by pressing "Esc" key.

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" showControls="true"/>

    ...

Figure 6.141. Usage "showControls" attribute

You can also position the controls relatively to the input field, by means of

- The "controlsHorizontalPosition" attribute with "left", "right" and "center" definitions

- The "controlsVerticalPosition " attribute with "bottom", "center" and "top" definitions

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" showControls="true" controlsVerticalPosition="bottom" controlsHorizontalPosition="left"/>

    ...

This is the result:

Figure 6.142. Positioning of "Save" and "Cancel" buttons

It is also possible to use "controls" facet in order to replace the default controls with facets content. See the example below.

Example:

    ...

    <rich:inplaceInput defaultLabel="Click here to edit" showControls="true" controlsHorizontalPosition="left" controlsVerticalPosition="bottom" id="inplaceInput">

        <f:facet name="controls">

            <button onclick="#{rich:component('inplaceInput')}.save();" type="button">Save</button>

            <button onclick="#{rich:component('inplaceInput')}.cancel();" type="button">Cancel</button>

        </f:facet>

    </rich:inplaceInput>

    ...

This is the result:

Figure 6.143. "controls" facet usage

## Note:

The "controls" facet also implies using "showControls" attribute and it has to be defined as "true".

Redefinition of the "save" and "cancel" icons can be performed using "saveControlIcon" and "cancelControlIcon" attributes. You need to define the path to where your images are located.

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" defaultLabel='click to edit'

        showControls="true"

        controlsHorizontalPosition="left"

        controlsVerticalPosition="top"

        saveControlIcon="/images/cancel.gif"

        cancelControlIcon="/images/save.gif"/>

        ...

Figure 6.144. Redefining of "save" and "cancel" buttons

The <rich:inplaceInput> component could be rendered with <span> or <div> elements to display its value. In order to change default <span> output, use "layout" attribute with "block" value.

The <rich:inplaceInput> component supports standard "tabindex" attribute. When the component gets focus the edit mode is activated.

The "inputWidth" , "minInputWidth" , "maxInputWidth" attributes are provided to specify the width, minimal width and maximal width for the input element respectively.

Table 6.240. Keyboard usage

Keys and combinations | Description
--- | ---
ENTER | Saves the input data, and changes the state from edit to changed
ESC | Changes the state from edit to view or changed, value is not affected
TAB | Switches between the components

### 6.58.6. JavaScript API

Table 6.241. JavaScript API

Function | Description
--- | ---
edit() | Changes the state to edit
cancel() | Changes its state to the previous one before editing (changed or view)
save() | Changes its state to changed with a new value
getValue() | Gets the current value
setValue(newValue) | Sets the current value (to be implemented)

### 6.58.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:inplaceInput> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:inplaceInput> component

Table 6.246. Class name for the view state

Class name | Description
--- | ---
rich-inplace-view | Defines styles for the view state
rich-inplace-input-view-hover | Defines styles for hovered text in the view state

Table 6.247. Class name for the input field in edit state

Class name | Description
--- | ---
rich-inplace-field | Defines styles for input field look and feel in edit state

Table 6.248. Class name for the "Changed" state

Class name | Description
--- | ---
rich-inplace-changed | Defines styles for the "Changed" state
rich-inplace-input-changed-hover | Defines styles for the hovered text in the "Changed" state

Table 6.249. Classes names "save" and "cancel" controls in Edit state

Class name | Description
--- | ---
rich-inplace-control | Defines styles for the controls
rich-inplace-control-press | Defines styles for the controls when either of the buttons is pressed
rich-inplace-shadow-size | Defines size of the shadow

rich-inplace-shadow-tr | Defines styles for the shadow in the top right corner
rich-inplace-shadow-bl | Defines styles for the shadow in the bottom left corner
rich-inplace-shadow-br | Defines styles for the shadow in the bottom right corner

In order to redefine styles for all <rich:inplaceInput> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-inplace-field {

        font-style: italic;

    }

    ...

This is the result:

Figure 6.146. Redefinition styles with predefined classes

In the shown example the font in edit state is changed to bold.

It's aslo possible to change styles of a particular <rich:inplaceInput> component. In this case you should create own style classes and use them in corresponding <rich:inplaceInput> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass {

        color:  #008cca;

    }

    ...

The "viewClass" attribute for the <rich:inplaceInput> is defined as it's shown in the example below:

Example:

    ...<rich:inplaceInput value="click to edit" styleClass="myClass"/>

This is a result:

Figure 6.147. Modificaton of a look and feel with own classes and styleClass attributes

As it could be seen on the picture above, the font color of the text on the component was changed.
