Systems and methods for managing authority designation and event handling for hierarchical graphical user interfaces

Abstract

Prior art attempts to manage authority designation in GUI-based computer systems have set up various 'handshaking' schemes between a graphics management system, such as a window server, and the various processes that are attempting to offer and accept access to each other. However, these schemes have certain limitations. In particular, when windows are used as the 'fundamental basis' for implementing authority designation, events that should treat all content within a window identically can't do so because, even though all content in the window may appear to be “owned” by the window, there may be some other process that is actually rendering the content to some portion of the window. Thus, described herein are systems and methods to manage authority designation and event handling within “hierarchical” GUIs using “handshaking” schemes that are secure, sub-window granular, and that generalize recursively when applied to the various graphical layers used to construct the windows.
