02 The class ContainerFrame

This class is a derivation of the class ReportFrame an inherits all the attributes from it. There is only one additional attribute which can hold an array of frames. It is an abstract base class for the SerialFrame or BoxFrame classes which I describe later in this document.

This class offers all the necessary functions to manage the array of frames. The array can hold any kind of frame type which is derived from ReportFrame.

You can add a frame by calling the addFrame function. The new added frame is added at the end of the container. There are also functions to remove one or all frame or to get a certain frame (getFrame, removeFrame and clearFrames). Because a container frame can contain other containers you can create a highly recursive tree structure. The library calculates the size of the frame by calculating recursively the sizes of all the inner frames.
