Description

  The present invention relates to a window system capable of operating a plurality of programs having windows composed of window parts in a single window under a multi-window system. A window part is a display element of a window and is directly managed by a multi-window system.

In Just Window (registered trademark) operating on MS-DOS (registered trademark) which is one of the OSs of personal computers and Palm (registered trademark) of PDA, a plurality of programs can be used in parallel by switching the screen. However, these do not operate under a multi-window system.
Also, a browser that displays an html file can change the display content of the browser by switching the html file to another html file. However, the display content of the browser is displayed by the browser based on the html file and is not a window component managed by the multi-window system.
In a window under the multi-window system, there is a method called MDI that creates a child window in a window, but this does not switch windows. There is also a method called card layout or tab display. In this method, a plurality of display elements are displayed in advance and the display content is changed by moving the display element to the top, and the window itself is not switched.

A window composed of window parts under the multi-window system cannot be displayed by switching to another window with a single window, such as the just window (registered trademark). Therefore, a new window is opened to display different contents.

  Java Applet (registered trademark) is a JAVA (registered trademark) program that runs on a virtual computer (virtual machine) whose display area is a browser window.

In Java Applet (registered trademark), it is possible to display a window composed of window parts in a display area of a browser. However, the Java Applet (registered trademark) itself cannot switch and display the window composed of the window parts so that the browser displaying the html file switches the screen.

  Therefore, it is not possible to operate a plurality of programs having windows composed of window parts in a single window of Java Applet (registered trademark) and use the plurality of programs in parallel while switching the display.

  In view of such a conventional situation, an object of the present invention is configured by a window component in a single window (hereinafter referred to as a single window) such as Java Applet (registered trademark) operating under a multi-window system. A plurality of programs having windows are operated, the windows of the plurality of programs are switched and displayed in the single window, and a plurality of programs can be used in parallel in the previous period.

In order to achieve the above object, a first feature of the window system of the present invention is a means for starting a program by a button, a menu, or the like in a single window such as Java Applet (registered trademark) operating under a multi-window system. (Hereinafter referred to as a program menu or the like) and a plurality of programs can be started.

In order to achieve the above object, a second feature of the window system of the present invention is that the activated program generates a window composed of window parts under the multi-window system. The window composed of window parts under the multi-window system means a set of window parts under the multi-window system (hereinafter referred to as a program window).

In order to achieve the above object, a third feature of the window system of the present invention is that, in the single window, the generation is performed using a technique already described in the specification of PCT / JP2005 / 007307 by the present applicant. The displayed program window is switched and displayed in the single window.
Here, the technique described in the specification of PCT / JP2005 / 007307 will be described.
A window in the multi-window system is generated and then drawn in the display area. The display device displays the contents drawn in the display area. For example, when a window size is changed or moved, a window that needs to be redrawn is drawn in the display area. At this time, if the overlapping state with other windows is not drawn properly, it is not correctly displayed on the display device. Such a management is performed by a multi-window system.
A program window associated with the generated single window program menu or the like is started when the program menu or the like is clicked, and a program window already associated with the generated single window or the like. Can be switched to the window of the program generated by the activated program. However, since the changed program window is not drawn in the display area, the program window before the change remains displayed on the display device.
Here, for example, if the size of the single window is slightly changed after switching the program window, the window program associated with the switching and the single window are both drawn in the display area and are displayed on the display device. It is displayed.

In order to achieve the above object, a fourth feature of the window system of the present invention is that it has a function (hereinafter referred to as a task bar or the like) for displaying the operating program in the single window.

  In order to achieve the above object, according to a fifth feature of the window system of the present invention, one of the operating programs displayed on the task bar or the like is selected in the single window (hereinafter referred to as click or the like). By using the technique already described in the specification of PCT / JP2005 / 007307 by the present applicant, the window of the clicked program is switched in the single window.

  In the above description, the window system is taken as an example. However, the present invention provides a window display method, a program, a computer system including the program, a program development support apparatus, a program for the development support apparatus, a recording medium storing these, and a computer system. The present invention can also be applied to a server (including a proxy server) including a providing means to provide.

  As described above, according to the first, second, third, fourth, and fifth features of the present invention, a plurality of programs are operated and switched between them in a single window under the multi-window system. Can be used.

  When the present invention is applied to JAVA Applet (registered trademark), a single window of JAVA Applet (registered trademark) can be used by switching a plurality of program windows in parallel.

JAVA Applet (registered trademark) runs on many platforms without depending on the OS or hardware. For this reason, terminals other than Windows (registered trademark) can be used, and the choices of terminals are widened, thereby reducing costs.

JAVA Applet (registered trademark) can prevent access to files on the terminal. When the present invention is applied to JAVA Applet (registered trademark), a plurality of programs that use only data in the server and do not leave data in the terminal can be used in parallel in a single window.

When the present invention is applied to JAVA Applet (registered trademark), a plurality of programs can be used simultaneously in the same virtual machine, and data can be exchanged between these programs. For example, if a document creation program and a spreadsheet program are run simultaneously, data exchange between these programs becomes possible.

Also, if a terminal that operates JAVA Applet (registered trademark), which is widely used as a standard technology, is connected to the Internet, it will be possible to work remotely without taking out data, and there is a risk of information leakage. Convenience improves at the same time as it decreases.

    Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1, 2, and 3.

  FIG. 1 is a diagram showing a screen of JAVA Applet (registered trademark) which is one embodiment of the present invention, FIG. 2 is a system configuration diagram of one embodiment of the present invention, and FIG. 3 shows an html file in a browser. It is a block diagram of the conventional system to display. The present invention will be described below with reference to these drawings.

Reference numeral 4 in FIG. 1 is a menu for starting a program in the JAVA Applet (registered trademark), and programs 23b in FIG. 2, FIG. 2 and 23c in FIG. By clicking this menu, a program, that is, 23b and 23c in FIG.

Reference numeral 6 in FIG. 1 denotes an area for displaying a window such as 23b and 23c in the program FIG. 2, and a window composed of window parts is displayed. The window composed of the window parts means a pair of window parts under the multi-window system (hereinafter referred to as a program window). Reference numeral 5 in FIG. 1 denotes a button for ending the JAVA Applet (registered trademark). When this button is clicked, the program started from the program menu or the like is terminated, and then the JAVA Applet itself is terminated.

  First, when the browser 27 in FIG. 2 is activated, the browser window 22 in FIG. 2 is displayed.

Next, when JAVA Applet (registered trademark) of this embodiment is activated from the browser, JAVA virtual machine 24 in FIG. 2 is activated, and program 1 23a in FIG. 2 is activated in the virtual machine. The first window like 2 is displayed. At this time, since there is no program started from the program menu or the like, the active program is not displayed in the task bar 3 of FIG.

  At this time, the task bar 3 in FIG. 1, that is, 21d in FIG. 2, is associated with the browser window 22 in FIG. 2, and is managed by the multi-window system 26 in FIG. Similarly, the program start menu 4 in FIG. 1, ie, 21c in FIG. 2, the button 5 in FIG. 1, ie, 21b in FIG. 2, and the program window 6 in FIG. 1, ie, 21a in FIG. Multi-window system 26 is managed in FIG.

  Program Menu Clicking 4 in FIG. 1 starts the registered program. Taking the case where the program 2 registered at the top of the program menu is activated as an example, the program 2 23b in FIG. 2 is activated. The program 2 generates a program window 21a in FIG. 2, switches from the program window already associated with the browser window to the generated program window, and associates it with the browser window 22 in FIG. . Next, the program 2 slightly changes the size of the browser window. Due to the change in the size of the window, the program windows associated with the browser window are both drawn in the drawing area and displayed on the display device. Through the above series of processing, the program display area 6 in FIG. 1 is switched to the window of the activated program. Changing the size of the window is exemplary and other states of the window may be changed.

  When the task bar 3a, 3b, etc. in FIG. 1 is clicked, the contents of the program display area 6 in FIG. 1 are switched to the program window generated by the clicked program. The mechanism for switching the program window is the same as that for starting the program. At this time, the program window and display contents that were previously displayed are saved and used when they are displayed again. Alternatively, a part or all of the previously displayed program window may be deleted, part or all of the display content may be saved, and a program window may be created when displayed again. Further, the program window and display contents that were previously displayed may be deleted, and a new program window and display contents may be created when the program window is displayed again.

  As described above, in a single window under the multi-window system, a plurality of programs for displaying windows composed of window parts can be operated in parallel in the same virtual machine.
