Method to support applications that allocate shareable or non-shareable colorcells in a conferencing network system having a hetergeneous hardware environment

摘要

A method for an X windows conferencing enabler to support applications that use non-shareable color cells while running in a conference in which the various X server participants differ in their support of visual classes is disclosed. In the method, an application request to allocate and initialize non-shareable colorcells and is displayed in a conference such that the colors for each X server participant are as close to that requested by the application as the hardware supports. The conference enabler distributes all of the non-shareable requests to each participant in the conference that supports the requests. For those participants that do not support those requests, a NoOp request is sent in place of the allocation requests and an AllocColor or AllocNamedColor is sent in place of the initialization request. Errors and replies are moderated so that the application only receives those errors and replies that are consistent with its X server's expected behavior.
