The Frame class implements a frame or group box in which you can create other controls as children. This is typically used in dialogs to group together a set of controls. For example, a set of radio buttons defined in a Frame object form a single group in which only one radio button can be selected at a time; a different set of radio buttons in a different Frame object will form a separate, independent group.

You can also use a Frame to contain a set of controls, such as Buttons or ToolButtons, which you want to move together on the window (for example, so they act as a toolbar which can be positioned along the top or bottom of the window).

Whether the group box title (caption property) is shown depends on the style property. If style is 0, the caption is shown. If style is 1, it is not.

If you want to display geometric shapes and draw text on the frame, you can use the Draw method.
