When you define an element or connector shape using a Shape Script, you can build the shape from separate components, defined as sub-shapes. Using sub-shapes, you can create complex shapes that more closely resemble the objects that they represent.
To set the layout type you use the layoutType attribute, which must be set in the initialization attributes section of the script; in other words, before any of the methods are called. Valid values for this attribute are:
- LeftRight - Shapes with this layout position the sub-shapes side by side, with the first added on the left, and subsequent sub-shapes to the right
- TopDown - Places the sub-shapes in a vertical arrangement, with the first sub-shape added to the top and subsequent sub-shapes added beneath
- Border - This requires an additional argument to the addsubshape method to specify which region of the containing shape the sub-shape is to occupy: N, E, S, W or CENTER; each region can only be occupied by one sub-shape
A sub-shape that is assigned to the E or W region must have its preferredwidth attribute specified in its declaration and, similarly, sub-shapes added to N or S must have their preferredheight attribute set; in this case, the values for these attributes are treated as static lengths and do not scale glyphs
The script defines this shape:
