Abstract

A system and process for ensuring the smooth flow of electronic ink is described. Dynamic rendering is give priority over other event handlers. Priority may be the use of one or more queues to order when events occur and may be performing dynamic rendering prior to other steps.

Claims

1. A computer system for attaching objects to a software component, said software component having a synchronous interface and an asynchronous interface, said computer system comprising:

means for determining whether a software plug-in object needs to be handled synchronously with received input or whether said software plug-in object can be processed at a later time;

means for attaching said software plug-in to one of a synchronous interface or an asynchronous interface based on an output from said means for determining.

2. The computer system according to claim 1, wherein at least one rendering plug-in object is attached to said synchronous interface.

3. The computer system according to claim 1, wherein time-critical plug-in objects are attached to said synchronous interface and non-time-critical plug-in objects are attached to said asynchronous interface.
