Japanese Patent Laid-Open No. 7-200266

  When performing a drag and drop operation, various situations can be considered. For example, a part of a window to which the user intends to drop overlaps with another window, and a desired part is not displayed. It is done. In such a case, the user himself / herself operates the corresponding window to display a desired drop position, or while dragging and dropping, the user moves the cursor to the folder on the task bar and displays the corresponding folder on the foreground. Such a complicated operation is required. In addition, for example, a situation may be considered in which a part of the drop destination window intended by the user protrudes from the screen area (desktop screen) and a desired part is not displayed. In such a case, it is necessary to move the corresponding window until the desired drop position is displayed by the user's own operation, which is complicated. This was also a problem when using a mouse as an input device. However, especially when the input device is composed of a digitizer and a dedicated pen, the user can perform drag operations as easily as a mouse. is not. In particular, since the larger the screen is, the more complicated it is, there has been a demand for realizing a drag and drop operation as easily as possible.

Even when the drop destination area is not displayed at the start of dragging, the drop destination area is displayed without requiring the user to adjust the position of the drop destination area in advance. The purpose is to let you.

Therefore, the present invention is configured to move or copy the information included in the first area in the screen area to the second area in the screen area based on a drag operation via the input device. A first determination means for determining whether or not there is an area displayed in front of the area, and an area displayed in front of the second area by the first determination means; If it is determined that the second area is present, the first area display control means for controlling the second area to be brought to the forefront and the second area brought to the forefront by the first area display control means are displayed. A second determination means for determining whether or not the image is displayed outside the screen area of the device; and the second area is displayed by the second determination means so as to protrude from the screen area of the display device. If it is determined And having a, a second region display control means for controlling so as to move the second region so that the entire area is displayed on the screen region of the second region.

  Further, the present invention provides the second information when the information included in the first area in the screen area is moved or copied to the second area in the screen area based on a drag operation via the input device. Determining means for determining whether or not the area is displayed protruding from the screen area of the display device; and the determining means determines that the second area is displayed protruding from the screen area of the display device. An area display control means for controlling to move the second area to the center of the screen area.

  Further, the present invention may be a region display method, a program, and a storage medium.

  According to the present invention, even when the drop destination area is not displayed at the start of dragging, the drop destination area can be displayed without requiring the user to adjust the position of the drop destination area in advance.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 is a diagram illustrating an example of a hardware configuration of the information processing apparatus.
The information processing apparatus 100 includes a CPU 111, a RAM 112, a ROM 113, an HDD 114, a network I / F 115, an input device interface 116, a display I / F 117, and a bus 121.
The CPU 111 controls the entire computer (information processing apparatus). A RAM (Random Access Memory) 112 is used as a work memory necessary for the operation of the CPU 111. A ROM (Read Only Memory) 113 stores instructions and data necessary for the CPU 111.

  An HDD (Hard Disk Drive) 114 stores a program for realizing the area display method (or area display processing) in the present embodiment. The CPU 111 reads out the program stored in the HDD 114 to the RAM 112 or the like and executes it, thereby realizing the region display method (or region display processing or drag and drop processing) in the present embodiment.

The network I / F 115 processes communication control for connecting to the network, but may not be in the present embodiment. The input device interface 116 connects a keyboard 118 and a mouse 119 of the input device. The display I / F 117 connects to the display device 120 and performs display.
Each block from the CPU 111 to the display I / F 117 is connected to the bus 121.

FIG. 2 is a diagram illustrating an example of a functional configuration of the information processing apparatus.
The input device 210 includes a keyboard 118 and a mouse 119.
In response to an instruction from the input device 210, the cursor control unit 201 controls the cursor displayed on the screen area. In response to an instruction from the input device 210 (based on a drag operation via the input device 210), the cursor control unit 201 also performs control for starting dragging on a file, an object, or the like.

The drag start / end detection unit 202 detects the start or end of the drag under the control of the cursor control unit 201.
The information storage unit 203 stores information inside the information processing apparatus such as files and objects to be dragged, cursor information, window information, and the like.
The cursor position determination unit 204 determines at which position in the screen area the cursor is located based on the information stored in the information storage unit 203.

The window position determination unit 205 determines at which position in the screen area the window is located based on information stored in the information storage unit 203.
The window position control unit 206 controls the window position.
The display device 120 displays the result processed in the information processing device 100.

Next, the drag and drop process according to this embodiment will be described with reference to the flowchart in FIG. 3 and the screen examples in FIGS.
FIG. 3 is a flowchart illustrating an example of the drag and drop process.
Upon receiving an instruction from the input device 210, the cursor control unit 201 starts dragging the file X in the window A in FIG. 4 as a start process (step S3-1). The start of the drag is detected by the drag start / end detection unit 202, and thereafter, the information processing apparatus 100 recognizes that the drag is being performed until the drop process is performed.

An example of the screen in the initial state immediately after the start of dragging is shown in FIG. FIG. 4 is a diagram illustrating a screen example in an initial state immediately after the start of dragging. The user's purpose is to move the file X (information) in the window A (first area) to the target folder Y (second area) in the window B.
Upon receiving an instruction from the input device 210, the cursor control unit 201 moves the cursor to the drag destination window (step S3-2). Then, the cursor position determination unit 204 determines that the cursor is on the window B. Next, in step S3-3, for example, the cursor control unit 201 determines whether or not the user stops the input from the input device 210 while being dragged at a specific portion on the window B and stops the cursor for a certain time. (Judge) (stop decision). If the cursor control unit 201 determines that the user stops the input from the input device 210 while dragging in a specific portion on the window B and stops the cursor for a certain period of time, the process proceeds to step S3-4. On the other hand, if the cursor control unit 201 determines that the user has stopped the input from the input device 210 while dragging in a specific portion on the window B and has not stopped the cursor for a certain period of time, the process proceeds to step S3-10. .

In step S <b> 3-4, the window position determination unit 205 determines the position and state of the window B, and determines whether there is a window that overlaps the front of the window B. If the window position determination unit 205 determines that there is a window overlapping the front of the window B, the process proceeds to step S3-5. On the other hand, when the window position determination unit 205 determines that there is no window overlapping the front of the window B, the window position determination unit 205 advances the process to step S3-6.
In step S3-5, the window position control unit 206 performs control so that the window B is arranged in the foreground (area display control). An example of a screen immediately after this process is performed is shown in FIG. FIG. 5 is a diagram illustrating an example of a screen after the window B is controlled to be placed on the foreground.

In the determination (determination) in step S3-3, the cursor control unit 201 advances the processing to step S3-4 at the moment when the stop time is zero, that is, when the cursor is on a specific part on the window B. Also good. In the present embodiment, the specific portion is the title bar of the window, but it is not necessarily the title bar, and may be, for example, a window corner.
When the drop target is already displayed, the user does not need to stop the cursor at a specific portion on the window B for a certain period of time. Therefore, the user does not stop the cursor at a specific portion on the window B for a certain period of time, and the cursor control unit 201 advances the process to step S3-10. In such a case, the cursor control unit 201 determines in step S3-10 that the drop preparation has been completed, and advances the process to step S3-11.

  Here, the window B is displayed in the foreground in FIG. 5, but in the example of FIG. 5, the target folder Y to be subjected to the drop processing protrudes from the screen area of the desktop. In order to cope with such a case, in step S3-6, the window position determination unit 205 determines whether or not the entire area of the window B is displayed on the desktop screen. If window position determination section 205 determines that the entire area of window B is displayed on the desktop screen, processing proceeds to step S3-9. On the other hand, if window position determination section 205 determines that the entire area of window B is not displayed on the desktop screen, the process proceeds to step S3-7.

In step S3-7, the window position control unit 206 controls the window B to move toward the center of the desktop screen (area display control). At this time, the cursor is controlled to move in conjunction with the window B by the cursor control unit 201.
In step S3-8, the cursor control unit 201 determines whether or not the cursor has been moved (resumption determination). If the cursor control unit 201 determines that the cursor has been moved, the process proceeds to step S3-9. If the cursor control unit 201 determines that the cursor has not been moved, the process proceeds to step S3-6.

As shown in FIG. 5, when the whole area of the window B is not displayed, the window position control unit 206 controls the window B to move toward the center of the desktop screen unless the cursor is moved.
In step S3-9, the window position control unit 206 stops the control (position control) of the window B that is the drag destination window. In step S3-10, the window position control unit 206 determines whether or not the drop preparation is completed based on whether or not the target folder Y that is the drop destination is displayed outside the screen area of the desktop. If the window position control unit 206 determines that the drop preparation has been completed, the process proceeds to step S3-11. If the window position control unit 206 determines that the drop preparation has not been completed, the window position control unit 206 proceeds to step S3-3.

  When the user moves the cursor with the input device 210 while the window B is moving toward the center of the desktop screen, the window position control unit 206 interrupts the window movement control. At this time, if the entire area of the window B has not yet been displayed in the desktop screen area, for example, the user again stops the cursor at a specific portion on the window B for a certain period of time. Then, the window position control unit 206 resumes the movement control from the position where the window movement control is interrupted.

In step S3-11, the cursor control unit 201 executes a drop process and ends the process illustrated in FIG.
FIG. 6 shows a state in which the window B is moved and the whole area of the window B is displayed. FIG. 6 is a diagram illustrating an example of a state in which the window B is moved and the entire area of the window B is displayed. As described above, the window position control unit 206 controls the movement of the window B until the entire area of the window B is displayed on the desktop screen unless the cursor is moved.
Note that the window position control unit 206 may return the window B to the original position after the drop processing is completed, or may display the window B as it is.

The object to be dragged and dropped can be any file, folder, object in the document, etc. The operation of this embodiment can be applied to all objects in a situation where dragging and dropping is possible on the operation system to be used. It is. For example, the operation (processing) of this embodiment can also be applied when an object in an opened electronic document is copied to another electronic document.
In this embodiment, the mouse 119 and the keyboard 118 are used as the input device 210. However, the input device 210 may be configured by a combination of a digitizer and a dedicated pen.

  As described above, according to the present embodiment, even when the drop destination area is not displayed at the start of dragging, the drop destination area can be displayed without requiring the user to adjust the position of the drop destination area in advance.
