JPH0628141A - Actuation controller for window - Google Patents

Abstract

PURPOSE:To perform processing for a window which is opened first while holding windows which are currently opened as they are by opening a window other than the windows which are currently opened. CONSTITUTION:As windows are opened in order, process names and file names corresponding to the respective windows are stored in a table 19 together with data indicating the depths of the layers of the respective windows. When a 3rd application process 18 is actuated, only one window corresponding to the process 18 is present on the desk top. When an item corresponding to a 2nd process 17 is selected in a submenu in this window by using a mouse 3, the press 18 takes the corresponding process name and file name out of the table 19 and sends a command to a control process 15. The control process 15 actuates and generates a 4th process 20 corresponding to the 2nd process 17 as an independent process and opens a window at a different position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device such as a document structure device having a tree-structured file system and a multi-window function, and more particularly to an activation control device for the window.

[0002]

2. Description of the Related Art There are various types of document creating apparatus,
One of them has a tree structure file system. In this tree-structured file system, each file has a hierarchical structure, and files are sequentially opened from an upper file to a lower file.

In a document creating apparatus having such a tree structure file system, when processing a lower file, the type of the file is schematically displayed on a desktop displayed on a display device such as a VDT (video display terminal device). A graphic called an icon is displayed in advance.
Then, first select the icon of the higher-level file on the desktop to open the window with instructions from the keyboard or mouse, select the file from the opened windows, and open the window again. Open the file. Then, processing such as document creation is performed with the target file opened.

Further, in such a document creating apparatus, a file existing on the desktop can be simultaneously opened to form a multi-window so that a plurality of files can be processed in parallel.

[0005]

In such a document creating apparatus, the window opened is only the last one opened. That is, a file opened in the middle becomes invisible because it is overlapped by windows of lower files in the file system opened thereafter. Therefore, it is necessary to close the window to get back to the opened window.

The files that can be multi-windowed are only files that exist independently of each other on the desktop. Therefore, if you want to process in parallel with windows in different layers in the middle, you need to copy the necessary files to the desktop in advance. Therefore, the operability was low.

The present invention provides a data processing device such as a document creation device which has the tree-structured file system and sequentially opens windows toward lower layers for processing.
It is an object of the present invention to provide a window start-up control device capable of processing a previously opened window without changing the currently opened window.

[0008]

In order to achieve the object, a window activation control device of the present invention is a tree in which files of a plurality of files existing in a desktop are sequentially opened in the same window from the higher order to the lower order. In a data processing device having a structured file system and capable of multi-window display, a means for sequentially storing a process name and a file name corresponding to each file in a table each time the file is opened; Means for inputting the layer depth of an already opened file desired by the operator to the application process to be processed, and extracting the corresponding process name and file name from the table according to the inputted layer depth Separately without changing the means and the window corresponding to the currently opened file The window corresponding to a file opened windows currently on the basis of the serial retrieved process name and file name, characterized in that a means for displaying in a different position.

[0009]

That is, in the present invention, as windows are sequentially opened, the process name and file name corresponding to each window are stored in the table together with the data indicating the depth of the hierarchy of the window. And /
When the operator inputs the depth of the hierarchy of the already opened file into the process of the application for processing each window, the table is searched and input by the application process corresponding to the currently opened window. The corresponding process name and file name are retrieved from the table according to the depth of the hierarchy of the windows. Then, a request to start the corresponding application process is sent to the control process. The control process activates the application process corresponding to this process name and file name as an independent process. For this independently started application process, a window different from the currently opened window is opened and enters the multi-window state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing an example of an apparatus to which the present invention is applied.

In the figure, 1 indicates a CPU, and the CPU
1 controls each program, keyboard 2 and mouse 3
It accepts, interprets, and executes an operator's instruction input from the device, and outputs a display signal to the display device 4 according to the result. The CPU 1 also receives image data from the scanner 5, executes document creation processing, transfers files to the printer 6, and the like.

The main memory 7 is used as an area for program execution, a table of process names, etc., and a work area for document creation. On the other hand, the external storage device 8
Is a large-capacity rewritable medium such as a magnetic disk, and is used as an auxiliary storage device during the processing of the file system and each program, and when the main storage device 7 runs out of capacity.

Keyboard 2, mouse 3 or scanner 5
The document file input by is put in somewhere in the tree-structured file system by the instruction of the keyboard 2 or the mouse 3 and is organized. Then, the file system is stored in the external storage device 8. A program for processing is also stored in the external storage device 8, loaded into the main storage device 7 as needed, and the processing is executed under the control of the CPU 1. The program includes an application process that manages windows and creates documents, and a control process that manages this application process.

On the screen of the display device 4, a desktop 9 as shown in FIG. 3 is displayed. This desktop 9 exists on the operator side, and the icon 10 and the icon 10
The application window 11 opened by and the application window 12 started as another window are displayed.

FIG. 4A is a diagram showing an example of the application window 11. That is, the application window 11 is divided into a title part 11a, a scroll part 11b, and an application area 11c for actually creating a document.

In the title portion 11a, there is a window menu 13 for window creation which is displayed as "window creation" as an application menu for the operator to create another window. 4 and by pressing the switch of the mouse 3
The submenu 14 is displayed as shown in (b). In the sub-menu 14, application processes that are higher than the application processes corresponding to the currently displayed application window 11 are numerically displayed in order from the highest order. For example, when the hierarchy of the application process corresponding to the application window 11 currently displayed is the third highest layer,
“1” and “2” are displayed on the submenu 14.

Next, along the flow of the operation of the operator,
The operation of this device will be described with reference to FIGS.

When any one of the icons 10 on the desktop 9 is selected and opened with the mouse 3, the control process 15 activates the first application process 16 and opens the application window 11. Further, when the item therein is selected and opened with the mouse 3, the second application process 17 is created as a child process of the first application process 16 (steps 101 to 1).
02), the corresponding window is displayed overlaid on the application window 11. At this time, the number of parent processes is increased by one (step 103), and
The application process name and file name are registered in the table 19 corresponding to the depth of the hierarchy of each process (step 104). In addition, similarly, the third application process 18 is activated as a child process of the second application process 17. In this state,
Only one application window 11 corresponding to the third application process 18 exists on the desktop 9. At this time, the first application process 16 and the second application process 17 are in a dormant state and are stored in the main storage device 7 or the external storage device 8.

Here, in order to perform file processing in the second application process 17 existing above the third application process 18, the window menu 13 of the application window 11 corresponding to the third application process 18 is moved to the mouse 3 The submenu 14 is opened by selecting with. At this time, if the number of parent processes is 0, the process proceeds to the next process without doing anything (steps 105 to 107). In the submenu 14, the second application process 17
By selecting "2" corresponding to "", hierarchy selection is performed (step 108), and the third application process 18 refers to the table 19 (step 109).
The corresponding process name and file name are fetched from this table 19, and a request, that is, a command for activating it as an independent process, not as a child process from the first application process 16 and generating it, is issued to the control process 15 (step 110). ).

The control process 15 receives this command and
The fourth application process 20 corresponding to the second application process 17 is activated and generated as an independent process, and the application window 12 is opened. Therefore, the application window 11 corresponding to the third application process 18 and the application window 12 corresponding to the fourth application process 20 are displayed on the desktop 9. If the generation of the application process fails, an error is displayed and then the process proceeds to the next process (steps 111 to 112).

As described above, since the application window 11 corresponding to the third application process 18 and the application window 12 corresponding to the fourth application process 20 are displayed in a multi-window state, processing of application processes of different hierarchies can be performed. Can be done in parallel.

In the embodiment described above, the window menu 13 and the submenu 14 for creating another application window 12 are present in the application window 11. However, without being bound by this, it is also possible to allocate these menus to the desktop 9 on the screen, reserve a part of the desktop 9 and put it there as a menu of the system. At this time, the windows to be instructed can be distinguished by assigning a number to each window and displaying the number when selecting the menu.

[0024]

As described above, in the window activation control device of the present invention, the application processes of different layers are activated independently in each application process. As a result, the currently opened window can be left as it is, and the previously opened windows can be separately opened to be in the multi-window state. Therefore, a desired file can be processed without performing an operation such as temporarily closing the lower window or copying the file, and the operability of the operator can be improved.
