摘要

The ARC / INFO Geographic Information System (GIS) computer program 28 supports multiple schedules of command line (TTY) and graphical user interface (GUI) operations. The TTY operation at the top of the thread is enabled to be controlled from the keyboard 20 via the terminal emulator 26 while the GUI operation at the top of the thread is controlled by the mouse using the window display 24 Program 28 to be controlled. The transition from the TTY to the GUI control of the program 28 in standalone form requires an instruction from the input stream while the transition from the GUI to the TTY control artificially triggers from the mouse 22 or keyboard 20. [ There is a need. The controller 44 of the present invention enables GUI control by inserting a dummy GUI operation 50 that includes a dummy window as a workpiece at the top of the TTY operation 46 of the straddle 48. The controller 44 removes the dummy window from the keyboard 20 or the user program so that the dummy GUI operation 50 is removed from the slade 48 and the TTY control is cleared from the keyboard 20 . The controller 44 then provides an instruction to the program 28 and inserts the dummy GUI operation 50 back onto the top of the TTY operation 46 of the thread 48 to enable subsequent GUI control do.
