Attachment Layout Manager (PRIM_ATLM)
Attachment Layout Manager
Ancestors - Base Layout Manager (PRIM_DTVW)Object (PRIM_OBJT)
Details
An attachment layout divides the container in to 5 types of cell - Top, Bottom, Left right and Center. Top and bottom fit to the width leaving the control's height unchanged. Left and Right fit to the height leaving the control's width unchanged. Center uses any remaining space. The IDE will manage layout definition through the use of the designer. This code is provided for reference purposes.
Example
Simple web page using an attachment layout showing how it divides the container.
