ColumnLayout.setVAlign

Sets the vertical alignment for all child controls of the container as a whole e.g. setting this property to Center will place all controls in the center of the container's vertical space. Use the #setCellVAlign(String) method to align each control within its containing table cell.

Supported values:

Value	Constant
Center	ControlConstants.VERTICAL_ALIGNMENT_CENTER
Top	ControlConstants.VERTICAL_ALIGNMENT_TOP
Bottom	ControlConstants.VERTICAL_ALIGNMENT_BOTTOM
Fill	ControlConstants.VERTICAL_ALIGNMENT_FILL

Setting a value of null removes any existing value for the property.
