摘要:
A dependent, nonprogrammable, character-based workstation terminal (DWS) supports a mouse. A terminal controller entirely within the DWS processes and displays mouse motions, but sends mouse button actuations, with the current mouse position, to a single workstation controller (WSC) handling many DWS'. The WSC processes the actuations according to a set of rules, and sends data streams to a main processor (MP) serving multiple WSCs. The MP executes user application programs, partially in response to data streams representing mouse events. The MP executes user application programs, partially in response to data streams representing mouse events. The MP may also send mouse rule sets to the WSCs in data streams.
摘要:
A method and apparatus for displaying entry fields on a workstation display screen, wherein a single entry field may be constructed having selectively positionable segments, and wherein each of the segments are linked together for processing, so that an entry field modification made in any of the segments will result in processing all of the segments for accommodating the modification; the method and apparatus are practiced in a system having a host processor, at least one workstation control interface, and a plurality of workstations.

A system for supporting graphics display sessions on remote terminals contains a processing subsystem dedicated to graphics support. Applications execute on a central processor, and display related graphics commands are executed on the separate graphics controller subsystem. The graphics subsystem is preferably connected to multiple remote terminals over a network, and communicates with them without requiring all work to be performed by the central processor which is executing the applications.
摘要:
A process for displaying cursor information for a plurality of dependent workstations from a remote processor or controller. Prestoring format tables for each dependent workstation in the controller or processor, processing cursor movement keystroke signals within the controller to define and selectively position the cursor for any dependent workstation when a cursor movement keystroke is made in that workstation, and commanding the dependent workstation to display either a selection cursor or a text cursor at the selected position.
摘要:
In a computing system including a host processor, a workstation controller, and a number of nonprogrammable workstations connected to the workstation controller, a method and apparatus to enable the workstation controller to construct and present action bars and pull-down menus for display at any designated workstation, and to process user interactions generated by keyboard signals at the workstation to control the selection and presentation of action bars and pull-down menus.
摘要:
A method and apparatus for constructing edit mask entry fields for display panel data, in a system including a host processor, a workstation controller, and a number of workstations, each workstation having a keyboard and display screen. The edit mask entry field mask positions are protected when display panel information is modified, by special hardware and software operations performed within the workstation controller. In particular, certain keyboard edit function keystrokes are processed by the workstation controller to permit the edit functions to be performed, without disturbing the position or display panel presentation of preselected edit mask characters.
摘要:
A workstation controller (WSC) performance monitor for locating performance bottlenecks is disclosed. The user notifies the host that he wants to start performance measurements. The host notifies each of the workstation controllers to begin collecting data that can be used to determine processor performance and communications line performance for each workstation controller. This data is collected in counters that reside in the storage of each of the workstation controllers. In the preferred embodiment, this data is periodically sent to a data base contained in the storage of the host. When the user specified length of time to collect data has expired, the host informs each of the connected workstation controllers to stop taking measurements. The data contained in the counters is sent to the database in the host and the host calculates processor utilization and communications line utilization for each of the connected workstation controllers. If the processor utilization falls below a first threshold, the performance of that processor is acceptable. If the processor utilization is greater than a second threshold, the performance of that processor is not acceptable. If the processor utilization is in between the first and second thresholds, the processor performance is considered marginal and a more complicated calculation of workload evenness of the processor is performed. If the workload is considered to be uneven, the performance of that processor is considered to be unacceptable.
摘要:
A method and system for visually altering characteristics of an iconic representation in response to a user's interaction with an object within a data processing system. The user initially associates an iconic representation for each object and selects the information to be monitored for each object. Parameters which may be monitored include the number of times the user interacts with the object, the amount of time the user spent interacting with the object, or the passage of time. This information is then stored in a database. The user's interaction with each object is then monitored, and the visual characteristics of the iconic representations associated with each object are then altered in response to the user's interaction with each object.
摘要:
A visually aging scroll bar is associated with a window or viewport on a computer display as part of a computer system, and contains a slider to indicate relative positioning in the window of a document, such as a data file, image file, audio file, text file, or spreadsheet. The current position of the scroll bar slider is monitored by the computer system. After a first predetermined sampling period has elapsed, a first region matching the current position of the scroll bar slider is created. The visual appearance of the region is determined by a predetermined region heating rate. For example, a newly created region starts at "cold", which can be indicated by a violet-indigo color. After a second sampling period has elapsed, the computer system again checks the current position of the scroll bar slider. If the current position still matches the first region, the visual appearance of the first region symbolically "warms up" as indicated by the region heating rate. This incrementally changing visual appearance (for example, from violet to indigo, blue, green, yellow, orange and finally a deep red) continues for as long as the current slider position matches the first region, up until a maximum region symbolic "temperature" is reached.
摘要:
A method and apparatus for distributing the processing of cursor-independent scrolling functions, between a host processor and a workstation via a workstation control interface, the workstation control interface being connected to a plurality of workstations, wherein the host processor formulates a data stream incorporating scrollable panel data, definitions of cursor-independent scrolling keys, definitions of scrolling increments, and definitions of scroll indicators; the data stream is transmitted to the workstation control interface, which may be embodied in a workstation controller (or PWS), and the workstation controller (or PWS) formulates a display screen image for transmission to a workstation to which it is connected. A cursor-independent scrolling request received from a workstation is received by the workstation controller (or PWS) and processed for scrolling without further communication with the host processor.
