<p>A method and apparatus for defining customizable pick, hit or find detection criteria for geometric types and using the results of the search as a basis for determining whether to perform an action. According to the inventive method, a search protocol is defined for geometric types. The search criteria is compared with graphic objects to determine whether the object matches the criteria. Based on the results of the comparison, an output is produced. In addition to allowing customized hit criteria for primitive geometric types, the hit object framework allows hit criteria to be specified for geometric types created by the application developer.</p> |
