Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a port display method in a display device applied to position a new port in an empty area on a physical screen such as a CRT display. .

(Prior art) For example, when arranging a new port or a port whose size has been changed on a physical screen (on a CRT display), in the past, a predetermined location in the upper left corner on the physical screen or existing before. The place was unconditionally positioned.

In the above-mentioned conventional apparatus, when a plurality of ports coexist, for example, in a multi-window environment, the ports are often overlapped, the screen becomes complicated, and the screen is often difficult to see. In order to avoid such inconvenience, for example, it is necessary to perform an operation of moving a designated port one by one, and there is a disadvantage that operability is poor.

(Problems to be Solved by the Invention) According to the above-described conventional port positioning device, as described above, there is a problem that the ports overlap each other, making it difficult to see the physical screen, and the operation of moving the ports is troublesome. .

The present invention solves the above-mentioned conventional problems, makes it easy to see a screen that tends to be complicated, and automatically sets an empty area (an area where no existing port exists) on the physical screen to facilitate the positioning operation. It is an object of the present invention to provide a port display method in a display device that can find and automatically position a new port at that location.

[Configuration of the Invention] (Means for Solving the Problems) The present invention divides a newly displayed port into four cells in a display device that displays a plurality of ports superimposed on a screen, and The screen of the display device is divided into a plurality of cells, and among the plurality of cells obtained by dividing the screen of the display device, a plurality of sets of four cells adjacent to each other are set as candidates for a new port arrangement location. For each set, the number of ports displayed in each cell constituting the set is counted, the number of ports displayed for each set is counted, and the displayed number of ports for each set is counted. , The new port is displayed in the set having the smallest number of displayed ports.

(Operation) According to the present invention, the physical screen is divided into a plurality of cells by dividing the physical screen into rectangles of ports to be arranged, and it is checked whether or not each cell has some existing ports. By positioning a new port in the cell with the minimum count, overlapping of ports can be prevented and port positioning operation can be facilitated.

(Embodiment) FIG. 1 is a block diagram showing a configuration of an embodiment of the present invention. 1 is a table storing a physical screen size, for example, a hardware FW information table, and 2 is a port position and size. Port management table, 3
Is a physical screen cell division mechanism that divides the physical screen into cells,
Reference numeral 4 denotes a cell evaluation mechanism, and reference numeral 5 denotes a port creation mechanism. The cell evaluation mechanism 4 and the port creation mechanism 5 detect the count of each cell and position a new port to the cell with the minimum count.

The operation of the embodiment of the present invention shown in FIG. 1 will be described. In FIG. 1, physical screen size information (CRTS) is obtained from the FW information table 1 and the physical screen is divided into cells by the physical screen cell dividing mechanism 3 in consideration of the size of the new port. Based on the division information (CEL), the number of existing ports for each cell is checked. Information (PORT) on the position and size of the existing port used at that time is obtained from the port management table 2. A new port is positioned by the port creation mechanism 5 in the optimal cell (OCEL) adopted by the cell evaluation mechanism 4.

FIG. 2 is a diagram for explaining the operation of one embodiment of the present invention. For example, when a new port T is positioned on a physical screen having existing ports P, Q, R, and S, the following is performed. In FIG. 2, a dotted rectangle represents each cell. In this case, the count of each cell (the number of existing ports) is as follows, and the cell is selected as the optimum cell from this.

... 1, 1, ... 0, ... 2, ... 2,
…… 1, ……………………………………………………………………………………………………………………………………………………………………………………………………… 1,
...... 1, 2.

In this method, a part extending over cells is not taken into consideration. Therefore, in order to realize more fine-grained optimization, the division unit is made finer, and a plurality of cells form a rectangle of a new port, that is, a candidate for an arrangement location. To do. In the evaluation, the sum of all the counts of the cells constituting the rectangle of the new port is used as the count of the location, and the location with the smallest count is adopted as the location of the port.

FIG. 3 shows an example in which the unit of division in each of the other embodiments of the present invention is set to 縦 each of the length and width of the new port T.
In the case of the embodiment shown in FIG. 3, from a set of four cells of,,, to a set of four,,,
35 sets are candidates for port arrangement. The count of each set is a composite of the counts of the cells constituting the set. For example, the count of the set,.
2 + 0 + 2 = 4. In this Fig. 3, the set,
, Are count zero and are adopted as the optimal set.

When dividing into cells, for example, if you start the division from the upper left corner of the physical screen, there will be inevitably too many parts on the right side and the lower side, which will not be considered at all, so the division was started from the upper left corner In addition to the above, for example, the same processing is performed on each cell when dividing from the remaining three corners of the upper right, the lower right, and the lower left, and finally the optimum is selected from among all the cells or the set. What is necessary is just to select a suitable port arrangement place.

(Effects of the Invention) According to the present invention, a new port is automatically positioned so as not to overlap with an existing port, so that the screen is easy to see, and the operator does not need to move the port, so that the man-machine interface can be used. Excellent effects such as greatly helping the improvement can be obtained.
