public class DecoratedPopupPanel
extends PopupPanel

A PopupPanel that wraps its content in a 3x3 grid, which allows users to add rounded corners.

Setting the Size:

If you set the width or height of the DecoratedPopupPanel, you need to set the height and width of the middleCenter cell to 100% so that the middleCenter cell takes up all of the available space. If you do not set the width and height of the DecoratedPopupPanel, it will wrap its contents tightly.

 .gwt-DecoratedPopupPanel .popupMiddleCenter {
   height: 100%;
   width: 100%;
 }

How to Override this Method

There are several important things that must take place in the correct order to properly remove a Widget from a Panel. Not all of these steps will be relevant to every Panel, but all of the steps must be considered.

1. Validate: Make sure this Panel is actually the parent of the child Widget; return false if it is not.
2. Orphan: Call Panel.orphan(Widget) first while the child Widget is still attached.
3. Physical Detach: Adjust the DOM to account for the removal of the child Widget. The Widget's Element must be physically removed from the DOM.
4. Logical Detach: Update the Panel's state variables to reflect the removal of the child Widget. Example: the Widget is removed from the Panel's WidgetCollection.

Specified by:

remove in interface HasWidgets

Overrides:

remove in class SimplePanel

Parameters:

w - the widget to be removed

Returns:

true if the child was present

setWidget

w - the panel's new widget, or null to clear the panel
