Frames inside a window are organized by line of cells. Each line can contain variable cells. The line and col parameters defines the order of the frame in the window. The real coordinates of a frame inside the work area of the root window depend on the frame sizes. And these sizes can be eventually changed by the user. The w and h parameters define the initial size of the frame.
The flags parameter defines special feature of the frame. See FrameSet() for a complet description of this parameter.
The frame uses the GEM widget of the window. Possible attributs for a frame are INFO, SIZER, HSLIDE, VSLIDE, UPARROW, DNARROW, LFARROW and RTARROW. Other widgets are ignored.
