Container GroupBox The GroupBox offers an easy way to combine RadioButtons to a RadioButtonGroup. The special functionality of this Control is to select just one selection object ( RadioButton ) at the same time. So if one of the objects get selected, the others automatically get deselected. Furthermore it is possible to set a node as default selected object. There can also be a Layouter attached as child of the GroupBox to order the RadioButtons. The visual appearance can be configured with a background image (9Patch Image) which can be resized by using the Layout.
