Creating visual objects

You can create all the kinds of visual objects you’ve seen in this book. There is a uniform syntax for all of them:

CREATE object-type handle [ IN WIDGET-POOL pool-name ]   [ASSIGN attribute = attribute-value [attribute = attribute-value ] . . . ]   [ trigger-phrase ] .

When you create an object dynamically you must associate it with a HANDLE variable (or possibly a handle field in a temp-table). This is the only way to reference the object after you create it. Unlike a static object, it has no name.

The WIDGET-POOL phrase lets you define a special storage area in memory where you want the object’s description to be located. The "Using named widget pools" section describes this phrase in more detail.
