About FrameBorderLayout and its Named Children

The frameBorderLayout component is a layout element for frames, supporting 11 named children that arrange frame child components in predefined, named areas. Each frameBorderLayout named child can contain one frame only. The frameBorderLayout named children (or named areas) are:

bottom - Lays out a frame at the bottom of the center frame.
center - Lays out a center frame. This must be specified.
end - Lays out a frame to the right of the center frame. If the reading direction is from right to left, lays out a frame to the left of the center frame.
innerEnd - Lays out a frame in the same area as innerRight. If the reading direction is from right to left, lays out a frame in the same area as defined by innerLeft.
innerLeft - Lays out a frame between the left frame and center frame.
innerRight -Lays out a frame between the right frame and center frame.
innerStart - Lays out a frame in the same area as defined by innerLeft. If the reading direction is from right to left, lays out a frame in the same area as defined by innerRight .
left - Lays out a frame to the left of the center frame.
right - Lays out a frame to the right of the center frame.
start - Lays out a frame to the left of the center frame. If the reading direction is from right to left, lays out a frame to the right of the center frame.
top - Lays out a frame at the top of the center frame.

Notes:

The frameBorderLayout component must be added inside a document component; it cannot be used inside a pageLayout component.
Use the alternateContent named child to provide non-frame content for browsers that do not support frames.
For the top and bottom frames, use the height attribute to specify the frame's height.
For all other child frames except center, use the width attribute to specify the frame's width.
If the reading direction is from left to right, right has precedence over end when both end and right are used. Similarly, left has precedence over start when both start and left are used. The same is true for innerEnd and innerRight , and innerStart and innerLeft.
