Abstract

PURPOSE:To easily execute a scroll indication in an arbitrary direction every time even if the screen on a view port exists on any rotary display unit to considerably improve an operation ability by considering the rotation information on the view port so as to decide a scroll direction at the time of processing a scroll. CONSTITUTION:A composite document processing device using a window, a view port and a frame icon has scroll derection conversion mechanism 13 which follows the scroll indication and decides the moving direction of the window based on the scroll direction and the rotary angle information of a display screen and a scroll execution mechanism 14 which executes the scroll process based on the scroll information obtained from the scroll direction conversion mechanism. Thus when data on a physical screen which is made to rotate is executed the scroll process by utilizing a frame icon function, between the up and down, left and right direction of the scroll instruction and the direction where the data actually scrolls any error doesn't occur, so that the smooth scroll process can be always executed regardless of the rotary angle of the view screen.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application gJI) The present invention uses a window, a viewport, and an icon to create a compound document containing a mixture of characters, figures, images, etc. It relates to a document processing device.

(Conventional example) Conventional scrolling using window viewports, stylish icons, etc. was realized by moving the window in that direction according to the scroll commands of the top, bottom, left, and right of the frame icon.

However, if this method is applied directly to rotated data, there will be a slight difference between the vertical and horizontal directions of the scroll command and the direction in which the data is actually scrolled.

This occurs after the rotated display is performed by rotating the viewport while remaining in the window. For example, in the case of a view that has been rotated 90 degrees,
When scrolling in the horizontal direction is executed, the data in the bit -rN- is scrolled in the vertical direction.

(Problems to be Solved by the Invention) As mentioned above, in the past, when the screen in the viewport is in the rotated display state, the display screen in the normal display state (the display screen at the rotation angle)
Since the scrolling direction is different from that in the previous case, there was a problem of poor operability.

The present invention determines the scroll direction by taking into account the rotation information of the view port during scroll processing, so that the scroll instruction direction always matches the direction in which data is actually scrolled. Regardless of whether the screen is rotated or displayed, scrolling in any direction can be easily performed, resulting in a marked improvement in operability.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a document processing device that uses a window, a viewport, and a frame icon, in which the scroll direction and the rotation angle of the display screen are adjusted in accordance with a scroll instruction. A configuration comprising a scroll direction conversion mechanism that determines the moving direction of the window based on information, and a scroll execution mechanism that executes scroll processing based on the scroll information obtained from the scroll direction conversion mechanism. It is said that

(Function) When the scroll direction conversion mechanism recognizes a scroll request by operating a specific icon provided in a predetermined area around the viewport, the scroll direction conversion mechanism converts the scroll direction based on the scroll instruction direction and the rotation angle information of the display screen in the viewport. The moving direction of the window is determined, and the scroll execution mechanism executes scrolling according to the determined direction.

This kind of scroll control function makes it possible to always match the direction in which the scroll is instructed and the direction in which the data actually scrolls. Therefore, no matter which rotation display state the screen in the viewport is in, it is always possible to move in any direction. Scroll instructions can be easily given, and operability is significantly improved.

(Example) An example of the present invention will be described below with reference to the drawings. still,
Here you can scroll by using the arrow (up, down, left, right) icons,
or vertical/horizontal elevators), and the screen rotation angle on the vinyl is 0/90°/1.
There are four types: 80°/270°.

FIG. 1 is a block diagram showing main components according to an embodiment of the present invention.

In the figure, 11 is a display mechanism having a display processor for displaying a compound document to be scrolled on a picture port, and here has a function of recognizing mouse icon (including elevator) selection operations.

12 is the display data rotation angle on the viewport (0°/90
This is a rotation update storage area in the memory in which rotation information indicating angles (°/180°/270°) is stored.

13 is a scroll request (Isc) from the display mechanism 1 above.
When the rotation information storage area 12 is received, a read request (RT) is output to obtain rotation information from the rotation information storage area 12.
This is a scroll conversion mechanism that obtains reverse rotation information (DT) and executes scroll direction conversion processing as shown in FIGS. 2 and 3 according to the information.

Reference numeral 14 denotes a scroll execution mechanism that executes scroll processing of the display screen in accordance with scroll information (SD) provided by the scroll conversion mechanism 13.

FIG. 2 is a flowchart showing the processing flow of scroll direction conversion in response to arrow icon operation, which is executed by the scroll converter Pilt13.

FIG. 3 is for explaining the scroll processing operation accompanying the elevator selection operation in the above embodiment.
, ) is a diagram showing the logical screen 21 and the intou 22 on the same screen, and FIG. The figure (c) shows that the view rotation is 90
The same display state when the figure (d) shows the busy rotation is 1.
The same display state is shown when the view rotation is 80', and the same display state is shown when the view rotation is 270 degrees. In the figure, EvL is a vertical elevator, and EVw is a horizontal elevator.

The operation of one embodiment will now be described with reference to FIGS. 1 to 3.

When the scroll direction mechanism 13 receives a scroll request (R2O) from the display mechanism 11, it outputs a read request (RT), reads rotation/information (DT) from the rotation information storage area 12, and reads this rotation information (DT). Executes conversion processing in the specified scroll direction according to the following. At this time, rotation information (DT)
The contents are 0', 90°, 180°.

270' (left rotation direction), and the scroll direction conversion mechanism 13 receives a scroll request (
aSC), the next scrolling direction is converted according to each of the above rotation angles.

The scroll conversion mechanism 13 sends a scroll request (RSC
) performs a unique conversion process depending on whether it is an arrow icon or an elevator.

That is, in the case of scrolling using an arrow icon, conversion is performed according to the following rules.

Scroll up → scroll right scroll down → scroll left scroll left scroll → scroll up scroll right scroll → scroll down
= 1), twice (t = 2) for 180°, and three times (1 = 3) for 270°, the above rule t-repeatedly being adapted. Note that no conversion is performed when the rotation angle of the vinyl screen is 0°. The conversion process flow at this time is shown in Figure 2 (Stella f
81-Ss).

Also, in case of scrolling by elevator.

At a rotation angle of 90°, 2706, Fig. 3(c)
, as shown in (,), in the horizontal elevator in the y direction, l
i! In the elevator, I realized the scroll in the X direction and reached 0°.

At a rotation angle of 180°, as shown in (b) and (d) of the same figure, the horizontal elevator is in the X direction, and the vertical elevator is in the y direction.
Implies directional scrolling. At this time, either method is determined depending on the rotation angle on the vinyl. For example, the rotation angle is 00
In the case of 1800, when the horizontal elevator is moved to the right, the window also shifts to the right, but in the case of 1800, when all the same operations are performed, the window is moved to the left.

As mentioned above, when using the frame icon function to scroll data on a physical screen that has been rotated by the conversion processing function of the scroll direction according to the rotation angle of the m-screen, the up and down of the scroll command Since there is no difference between the left and right direction and the direction in which data is actually scrolled, operability with respect to the user interface is improved, and scrolling operations can always be performed smoothly regardless of the rotation angle of the screen. look.

In the above embodiment, the rotation angle of the vinyl screen is 90'718.
Although the case of 0'/270° (7) 90' increments is shown as an example, it is easy to extend and apply the rotation to arbitrary angles.
