Extends
Methods
addAll(…child)
Adds one or more children to this widget. This method will flatten any
arrays among the arguments and ignores any null
or undefined
arguments.
Any DOM nodes or widgets will be added to the end, and other objects will be
converted to a text node first. Subclasses should normally override the
addChildNode()
method instead of this one, since that is the basis for
DOM node insertion.
- Parameters:
-
Name Type Attributes Description child
{string|Node|Array} <repeatable>
the children to add - Inherited From:
- RapidContext.Widget#addAll
- Source:
- RapidContext_Widget.js, line 570
addChildNode(child)
Adds a single child DOM node to this widget. This method is sometimes overridden by child widgets in order to hide or control intermediate DOM nodes required by the widget.
- Parameters:
-
Name Type Description child
{Widget|Node} the DOM node to add - Inherited From:
- RapidContext.Widget#addChildNode
- Source:
- RapidContext_Widget.js, line 534
addClass(…cls)
Adds the specified CSS class names to this HTML DOM node.
- Parameters:
-
Name Type Attributes Description cls
{string|Array} <repeatable>
the CSS class names to add - Inherited From:
- RapidContext.Widget#addClass
- Source:
- RapidContext_Widget.js, line 333
animate(opts)
Performs a visual effect animation on this widget. This is
implemented using the MochiKit.Visual
effect package. All options
sent to this function will be passed on to the appropriate
MochiKit.Visual
function.
- Parameters:
-
Name Type Description opts
{Object} the visual effect options Properties
Name Type Description effect
{string} the MochiKit.Visual effect name queue
{string} the MochiKit.Visual queue handling, defaults to "replace" and a unique scope for each widget (see MochiKit.Visual
for full options) - Inherited From:
- RapidContext.Widget#animate
- Deprecated:
- Use CSS animations instead.
- Example:
-
widget.animate({ effect: "fade", duration: 0.5 }); widget.animate({ effect: "Move", transition: "spring", y: 300 });

blurAll()
Blurs (unfocuses) this DOM node and all relevant child nodes. This function
will recursively blur all <a>
, <button>
, <input>
, <textarea>
and
<select>
child nodes found.
- Inherited From:
- RapidContext.Widget#blurAll

destroy()
Destroys this widget.
- Overrides:
- RapidContext.Widget#destroy

- RapidContext_Widget_TableColumn.js, line 89
disable()
Disables this widget if it was previously enabled. This method is
equivalent to calling setAttrs({ disabled: true })
.
- Inherited From:
- RapidContext.Widget#disable
- Source:
- RapidContext_Widget.js, line 424
enable()
Enables this widget if it was previously disabled. This is
equivalent to calling setAttrs({ disabled: false })
.
- Inherited From:
- RapidContext.Widget#enable
- Source:
- RapidContext_Widget.js, line 416
getChildNodes() → {Array}
Returns an array with all child DOM nodes. Note that the array is
a real JavaScript array, not a dynamic NodeList
. This method is
sometimes overridden by child widgets in order to hide
intermediate DOM nodes required by the widget.
- Returns:
- {Array} the array of child DOM nodes
- Inherited From:
- RapidContext.Widget#getChildNodes
- Source:
- RapidContext_Widget.js, line 522
hasClass(…cls) → {boolean}
Checks if this HTML DOM node has the specified CSS class names. Note that more than one CSS class name may be checked, in which case all must be present.
- Parameters:
-
Name Type Attributes Description cls
{string|Array} <repeatable>
the CSS class names to check - Returns:
-
{boolean}
true
if all CSS classes were present, orfalse
otherwise - Inherited From:
- RapidContext.Widget#hasClass
- Source:
- RapidContext_Widget.js, line 315
hide()
Hides this widget node if it was previously visible. This method
is equivalent to calling setAttrs({ hidden: true })
. It is safe
for all types of widgets, since it only adds the widgetHidden
CSS class instead of setting the display
style property.
- Inherited From:
- RapidContext.Widget#hide
- Source:
- RapidContext_Widget.js, line 470
isDisabled() → {boolean}
Checks if this widget is disabled. This method checks both the
"widgetDisabled" CSS class and the disabled
property. Changes
to the disabled status can be made with enable()
, disable()
or
setAttrs()
.
- Returns:
-
{boolean}
true
if the widget is disabled, orfalse
otherwise - Inherited From:
- RapidContext.Widget#isDisabled
- Source:
- RapidContext_Widget.js, line 395
isHidden() → {boolean}
Checks if this widget node is hidden. This method checks for the
existence of the widgetHidden
CSS class. It does NOT check the
actual widget visibility (the display
style property set by
animations for example).
- Returns:
-
{boolean}
true
if the widget is hidden, orfalse
otherwise - Inherited From:
- RapidContext.Widget#isHidden
- Source:
- RapidContext_Widget.js, line 437
removeAll()
Removes all children to this widget. This method will also destroy and child
widgets and disconnect all signal listeners. This method uses the
getChildNodes()
and removeChildNode()
methods to find and remove the
individual child nodes.
- Inherited From:
- RapidContext.Widget#removeAll
- Source:
- RapidContext_Widget.js, line 582
removeChildNode(child)
Removes a single child DOM node from this widget. This method is sometimes overridden by child widgets in order to hide or control intermediate DOM nodes required by the widget.
Note that this method will NOT destroy the removed child widget, so care must be taken to ensure proper child widget destruction.
- Parameters:
-
Name Type Description child
{Widget|Node} the DOM node to remove - Inherited From:
- RapidContext.Widget#removeChildNode
- Source:
- RapidContext_Widget.js, line 553

- Source:
- RapidContext_Widget_TableColumn.js, line 130
setStyle(styles)
