Foreground window determination through process and thread initialization

摘要

A method, system and computer program product for foreground window determination of windows displaying applications in a displayed desktop. The present invention continuously resolves the issue of what program or process running or to be run in a window on the desktop is displayed in the foreground or focus window, thereby avoiding unintentional inputs to an application in a background window and unintentional switching of the application program presented in the foreground window of a windows-based operating system. The continuous resolution is made by determining if an initiated process has the special right for its window to become the foreground window; determining if the window associated with a process can take the foreground based on a set of predetermined process foreground rules and if the right was given with respect to the initiated process; determining if an initiated thread has the special right for its window to become the foreground window; and determining what window displayed or to be displayed is in the foreground when a thread requests for its associated window to take the foreground based on a set of predetermined thread foreground rules and if the right was given with respect to the initiated thread.
