    public abstract class CellPanel

extends ComplexPanel

A panel whose child widgets are contained within the cells of a table. Each cell's size may be set independently. Each child widget can take up a subset of its cell and can be aligned within it.

Note: This class is not related to the `Cell` based data presentation widgets such as `CellList` and `CellTable`.

### Use in UiBinder Templates

When working with CellPanel subclasses in `UiBinder` templates, wrap child widgets in `<g:cell>` elements. (Note the lower case "c", meant to signal that the cell is not a runtime object, and so cannot have a `ui:field` attribute.) Cell elements can have attributes setting their height, width and alignment.

#### <g:cell> attributes

horizontalAlignment
  Interpreted as a static member of `HasHorizontalAlignment.HorizontalAlignmentConstant` and used as the `align` argument to `setCellHorizontalAlignment(com.google.gwt.user.client.ui.Widget, com.google.gwt.user.client.ui.HasHorizontalAlignment.HorizontalAlignmentConstant)`
verticalAlignment
  Interpreted as a static member of `HasVerticalAlignment.VerticalAlignmentConstant` and used as the `align` argument to `setCellVerticalAlignment(com.google.gwt.user.client.ui.Widget, com.google.gwt.user.client.ui.HasVerticalAlignment.VerticalAlignmentConstant)`
width
  Used as the `width` argument to `setCellWidth(com.google.gwt.user.client.ui.Widget, java.lang.String)`
height
  Used as the `height` argument to `setCellHeight(com.google.gwt.user.client.ui.Widget, java.lang.String)`

For example:

     <g:HorizontalPanel>
       <g:cell width='5em' horizontalAlignment='ALIGN_RIGHT'>
         <g:Label ui:field='leftSide' />
       </g:cell>
       <g:cell width='15em' horizontalAlignment='ALIGN_LEFT'>
         <g:Label ui:field='rightSide' />
       </g:cell>
     </g:HorizontalPanel>

Constructor Detail

### CellPanel

    public CellPanel()

Method Detail

### getSpacing

    public int getSpacing()

  Gets the amount of spacing between this panel's cells.

  Returns:
    the inter-cell spacing, in pixels

### setBorderWidth

    public void setBorderWidth(int width)

  Sets the width of the border to be applied to all cells in this panel. This is particularly useful when debugging layouts, in that it allows you to see explicitly the cells that contain this panel's children.

  Parameters:
    `width` - the width of the panel's cell borders, in pixels

### setCellHeight

    public void setCellHeight(Widget w,
                              java.lang.String height)

  Sets the height of the cell associated with the given widget, related to the panel as a whole.

  Parameters:
    `w` - the widget whose cell height is to be set
    `height` - the cell's height, in CSS units

### setCellHeight

    public void setCellHeight(IsWidget w,
                              java.lang.String height)
