Whether this part is idle.
A part is idle if it is not initializing, rendering, or having any of it's options calculated.

Test whether the widget is visible.
A widget is visible when it is attached to the DOM, is not explicitly hidden, and has no explicitly hidden ancestors.

Set the parent of the widget.
Children are typically added to a widget by using a layout, which means user code will not normally set the parent widget directly.
The widget will be automatically removed from its old parent.
This is a no-op if there is no effective parent change.
The current state of the part
An object that describes additional detail about the state of this part. If the state is Error, the detail will be the actual error thrown. If the state is Calculating, the detail will be a string list of currently calculating options.
The title object for the widget.
The title object is used by some container widgets when displaying the widget alongside some title, such as a tab panel or side bar.
Since not all widgets will use the title, it is created on demand.
The owner property of the title is set to this widget.
An external ID that this part will be referenced by
A static identifier for this part set by PartFactory#registerPart.
Post an 'activate-request' message to the widget.
This is a simple convenience method for posting the message.

The class name to add to the node.
If the class name is already added to the node, this is a no-op.
The class name must not contain whitespace.
Request that the framework stop evaluating this part's options.
Create an iterator over the widget's children.
A new iterator over the children of the widget.
The widget must have a populated layout in order to have children.
If a layout is not installed, the returned iterator will be empty.

This is a simple convenience method for sending the message.
Test whether a widget is a descendant of this widget.
The descendant widget of interest.
true if the widget is a descendant, false otherwise.
Convenience for sending an error message to this part
Post a 'fit-request' message to the widget.
This is a simple convenience method for posting the message.
Test whether the widget's DOM node has the given class name.
The class name of interest.
true if the node has the class, false otherwise.
Invoke the message processing routine of the widget's layout.
The message to dispatch to the layout.
This is a no-op if the widget does not have a layout.
This will not typically be called directly by user code.

The default implementation of this handler is a no-op.
The framework is about to calculate this part's options
The default implementation of this function is a no-op

The default implementation of this handler is a no-op.
A message handler invoked on a 'before-show' message.
The default implementation of this handler is a no-op.
The part's option evaluations have been canceled.
The default implementation of this function is a no-op
A message handler invoked on a 'child-added' message.
The default implementation of this handler is a no-op.
A message handler invoked on a 'child-removed' message.
The default implementation of this handler is a no-op.
A message handler invoked on a 'close-request' message.
The default implementation unparents or detaches the widget.
An error occurred while this part was being evaluated.
The message can be investigated for more detail, such as when the error occurred or any detail provided with the error (such as a stack trace)
The default implementation of this function is a no-op
A message handler invoked on a 'fit-request' message.
The default implementation of this handler is a no-op.
An option, or set of options, has finished calculating
The default implementation of this function is a no-op. If an option errored out, it will be included in this message.
An option, or set of options, is now calculating.
The default implementation of this function is a no-op
A message handler invoked on a 'resize' message.
The default implementation of this handler is a no-op.
A message handler invoked on an 'update-request' message.
The default implementation of this handler is a no-op.
Convenience for sending option calculation updates to this part
Request that the framework refresh this part as soon as possible. This is used to do things like clearing error state and reconstructing IFrames after being removed from the DOM.
Remove a class name from the widget's DOM node.
The class name to remove from the node.
If the class name is not yet added to the node, this is a no-op.
The class name must not contain whitespace.
Show or hide the widget according to a boolean value.
true to hide the widget, or false to show it.
This is a convenience method for hide() and show().
Test whether the given widget flag is set.
This will not typically be called directly by user code.
Toggle a class name on the widget's DOM node.
The class name to toggle on the node.

remove the class (false). If not provided, the presence of
the class will be toggled from its current state.

Generated using TypeDoc
This part is a proxy/wrapper around kernel parts that live on the Kernel. The KPP uses a comm to connect to a kernel-side KernelPartManager, and use that to manage the lifecycle of a kernelside part.
Each part connects over the same comm, and that comm provides some helpers for syncing the available parts with the client-side part factory
