JPS63188227A - Display system for pull-down menu - Google Patents

Abstract

PURPOSE:To enable a user to continue operations without erasing original data by using a video data synthesizing circuit to display with transmission a pull-down menu when the pull-down is displayed with priority. CONSTITUTION:A pull-down menu is set at a graphic memory plane 5 or 6. The display size of the pull-down menu is set by a video data synthesizing circuit 9 and the display of the plane storing the pull-down menu is designated with priority in accordance with the contents stored in a control memory plane 7. The pull-down menu is displayed with transmission as a single hardware window when a transmission display is designated in a display mode. In such a way, the pull-down menu is displayed without erasing the original data and the working efficiency is improved with a pull-down menu display system.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a sol-down menu display system used in a workstation.

(Prior Art) In recent years, work stages for OA have appeared that can handle not only code information such as characters but also graphics, images, etc. in an integrated manner. Workstations that perform interactive processing use a technique called hi-to-pu control to output screens that are easy to understand, and use multi-window display to simultaneously display multiple pieces of information on the same screen. It has functions.

By the way, the gourmet menu display is known as an important operator interface in the work stage mentioned above.

(Problems to be Solved by the Invention) The Soldown Menu is a system 64 installed in application software etc. to facilitate the operation of EDE and used as a help function. In the conventional sol-down menu, the original image is moved back to the Kaifu area, deleted from the screen, a pull-down menu is displayed, and when the menu is deleted, the original image is returned to its original position. This is what was being displayed. Therefore, when the Soldown menu is displayed, the data is hidden and cannot be viewed, which is an inconvenience.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pull-down menu display system that allows a user to continue operations without deleting the original data even when a pull-down menu is displayed. purpose.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes a plurality of graphics memory planes and a control memory plane in which control data for changing the display priority in units of one or more dots is stored. and a video data synthesis circuit for synthesizing and displaying the graphics data read from each memory, and the video data synthesis circuit transparently displays when the pull-down menu is displayed with priority.

(Function) In the above configuration, the display size of the pull-down menu is set in the video data synthesis circuit that sets the pull-down menu in the graphics memory plane, and the pull-down menu is set according to the contents stored in the control memory plane.
Specifies the priority display of the plane where is stored. By specifying transparent display in the display mode, the pull-down menu is displayed transparently as one hardware window. This makes it possible to display the solve-down menu without erasing the original data, improving work efficiency.

(Example) Hereinafter, an example of the present invention will be described in detail using the drawings. FIG. 1 is a schematic diagram showing an embodiment of the present invention. In the figure, numeral 1 denotes a display controller (CRTC) that controls display on a CRT monitor (not shown), and reads out data for drawing and displaying display data. A text memory 2 stores code data among the text data, and a text attribution memory 3 stores attribute data among the text data. 4 is a character generator that converts code data obtained from the text memory 2 into a character pattern. 5 is a graphics memory for storing all the first graphics data, and 6 is a graphics memory for storing the second graphics data. Reference numeral 7 denotes a display priority control memory that stores control data for performing priority display control in units of display dots. 8
1 to 8d are parallel-to-serial conversion circuits for converting parallel data read from the character generator 4 and each memory 6, 6, and 7 into serial data; 9 is for synthesizing each serial data;
This is a video data synthesis circuit that generates video data.

The above display controller 1, text memory 2, text attribute memory 3, graphics memory 4, 5
, and the display priority control memory 7 are commonly connected to the data bus 10.

Hereinafter, the operation of the embodiment of the present invention will be explained in detail. Text data TX, graphics data GR1, GR, and control data CT read out from each memory 2, 5.6 and converted into serial data are simultaneously supplied to video data synthesis circuit 9. Here, a display window is defined that defines the range to be displayed for the graphics data GR. This is a CPU (not shown)
It is done well. Graphics data GR, TOGR
, the display priority is GR, )GR
However, graphics data GR□ is displayed outside the display window of graphics data GR.

By the way, in multi-window display, it is necessary to give priority to all windows and display interactive displays mainly based on instructions from the operator, such as pull-down menus. For this purpose, display priority control memory 7
The display of the graphics data GR□ is partially given top priority based on the control data CT output from the control data CT. Here, if data such as a pull-down menu is set in advance in a partial area of the graphics data GR, which is given the highest priority, the following control is possible. That is, first, the Soldown menu is set to graphics level 5 or 6. Display a pull-down menu on the video synthesis circuit 9.a) eSpecify all. As a result, by specifying transparent display in the display mode, the pull-down menu is displayed transparently as one hardware window.

[Effects of the Invention] As explained above, according to the present invention, the following effects can be obtained.

(1) Multi-window display using the Oparatsuno method is possible using text planes, double-sphere graphics, and cross-planes.

(2) A pull-down menu can be displayed without erasing the original data.

(3) It is possible to set the window like a heart 9 square 9
, it is possible to specify overlay (transparent/non-transparent) with the original data.

(4) Since the text and each of the multiple graphics and boxes are independent from each other, high-speed display is possible in a multitasking environment.
