The graphical objects that are grouped together to represent one attribute are called Group Controls. The graphical objects button, checkbox, and radio button are called Group Controls. For example, checkboxes can be used as the multiple choice answers for one question.
Group Controls do not leave their container and cause attribute disassociation. For example, if a Button is dragged from the Toolbox onto the Graphical Painter Form, then the parent of the Button is always the Form. If the Button is dragged into a GridPanel, then the parent of the Button is always the GridPanel.
