Known Indirect Subclasses

AbsolutePanel, CaptionPanel, CellPanel, ComplexPanel, DeckPanel, DecoratedPopupPanel, DecoratedStackPanel, DecoratedTabPanel, DecoratorPanel, DialogBox, DisclosurePanel, DockLayoutPanel, DockPanel, FlexTable, FlowPanel, and 26 others.

AbsolutePanel	An absolute panel positions all of its children absolutely, allowing them to overlap.
CaptionPanel	A panel that wraps its contents in a border with a caption that appears in the upper left corner of the border.
CellPanel	A panel whose child widgets are contained within the cells of a table.
ComplexPanel	Abstract base class for panels that can contain multiple child widgets.
DeckPanel	A panel that displays all of its child widgets in a 'deck', where only one can be visible at a time.
DecoratedPopupPanel	A `PopupPanel` that wraps its content in a 3x3 grid, which allows users to add rounded corners.
DecoratedStackPanel	A `StackPanel` that wraps each item in a 2x3 grid (six box), which allows users to add rounded corners.
DecoratedTabPanel	A `TabPanel` that uses a `DecoratedTabBar` with rounded corners.
DecoratorPanel	A `SimplePanel` that wraps its contents in stylized boxes, which can be used to add rounded corners to a `Widget`.
DialogBox	A form of popup that has a caption area at the top and can be dragged by the user.
DisclosurePanel	A widget that consists of a header and a content panel that discloses the content when a user clicks on the header.
DockLayoutPanel	A panel that lays its child widgets out "docked" at its outer edges, and allows its last widget to take up the remaining space in its center.
DockPanel	This class is deprecated. Use `DockLayoutPanel` instead, but understand that it is not a drop in replacement for this class. It requires standards mode, and is most easily used under a `RootLayoutPanel` (as opposed to a `RootPanel`
FlexTable	A flexible table that creates cells on demand.
FlowPanel	A panel that formats its child widgets using the default HTML layout behavior.
FocusPanel	A simple panel that makes its contents focusable, and adds the ability to catch mouse and keyboard events.
FormPanel	A panel that wraps its contents in an HTML <FORM> element.
Grid	A rectangular grid that can contain text, html, or a child `Widget` within its cells.
HTMLPanel	A panel that contains HTML, and which can attach child widgets to identified elements within that HTML.
HTMLTable	HTMLTable contains the common table algorithms for `Grid` and `FlexTable`.
HasWidgets.ForIsWidget	Extends this interface with convenience methods to handle `IsWidget`.
HorizontalPanel	A panel that lays all of its widgets out in a single horizontal column.
HorizontalSplitPanel	This class is deprecated. Use `SplitLayoutPanel` instead, but understand that it is not a drop in replacement for this class. It requires standards mode, and is most easily used under a `RootLayoutPanel` (as opposed to a `RootPanel`
LayoutPanel	A panel that lays its children out in arbitrary `layers` using the `Layout` class.
LazyPanel	Convenience class to help lazy loading.
LoggingPopup	A simple popup to show log messages, which can be resized, minimized, and dragged to a different location.
NullLoggingPopup	A class which can be substituted in for the BasicLoggingPopup in the the gwt.xml file to disable the default popup log handler.
Panel	Abstract base class for all panels, which are widgets that can contain other widgets.
PopupPanel	A panel that can "pop up" over other widgets.
RootLayoutPanel	A singleton implementation of `LayoutPanel` that always attaches itself to the document body (i.e.
RootPanel	The panel to which all other widgets must ultimately be added.
ScrollPanel	A simple panel that wraps its contents in a scrollable area.
SimplePanel	Base class for panels that contain only one widget.
SplitLayoutPanel	A panel that adds user-positioned splitters between each of its child widgets.
StackLayoutPanel	A panel that stacks its children vertically, displaying only one at a time, with a header for each child which the user can click to display.
StackPanel	A panel that stacks its children vertically, displaying only one at a time, with a header for each child which the user can click to display.
TabLayoutPanel	A panel that represents a tabbed set of pages, each of which contains another widget.
TabPanel	A panel that represents a tabbed set of pages, each of which contains another widget.
Tree	A standard hierarchical tree widget.
VerticalPanel	A panel that lays all of its widgets out in a single vertical column.
VerticalSplitPanel	This class is deprecated. Use `SplitLayoutPanel` instead, but understand that it is not a drop in replacement for this class. It requires standards mode, and is most easily used under a `RootLayoutPanel` (as opposed to a `RootPanel`

Inherited Methods

From interface java.lang.Iterable

Public Methods

public abstract void add (Widget w)

Adds a child widget.

Parameters

w	the widget to be added

Throws

UnsupportedOperationException	if this method is not supported (most often this means that a specific overload must be called)

public abstract void clear ()

Removes all child widgets.

public abstract Iterator<Widget> iterator ()

Gets an iterator for the contained widgets. This iterator is required to implement remove().

public abstract boolean remove (Widget w)

Removes a child widget.

Parameters

w	the widget to be removed

Returns

true if the widget was present
