More specifically, the present invention relates to a tree-structured document editor and a document editing method for easily editing a tree structure of various sizes and objects such as text, pictures, videos, charts, charts, and 3D models.

Recently, due to the rapid development of electronic communication technology, a computer for inputting a large amount of information, editing and storing in a specific form has been widely used.

In order to support the function of document editing by computer, many software developers have developed various types of document editors. Currently, Microsoft's Word and Office, Hangul and computer company's Hanga Hangul are used as representative document editors.

Most text editors currently in use provide additional functions such as inserting picture files, inserting tables, and inserting external documents, in addition to basic text input, and document structure information so that users can edit documents more efficiently. A window structure with a tree structure to briefly display the back is provided along with the document editing window.

However, in the document editor supporting the conventional tree structure as described above, since the edit window such as the area for displaying the tree and the data input area has a plural structure, the user selects a specific node of the tree to edit the document. There was an inconvenience in that the task could not be directly edited in a specific node of the tree but should be performed through a separate data edit window.

In addition, the document editor supporting the conventional tree structure has the same height of each node constituting the tree, and since each node constituting the tree supports only text, it is possible to use different images such as pictures, videos, charts, and charts. The problem is that objects cannot be edited directly on each node of the tree.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to easily and quickly edit objects of various sizes and data, such as text, pictures, videos, charts / charts, and application extension data, into a single tree structure.

Hereinafter, a tree structure document editor and a document editing method of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically showing the configuration of a tree structure text editor according to the present invention.

As shown, the tree structured document editor according to the present invention includes a key input means 10, a control means 20, a user interface means 30, a document management means 40, an output generating means 50. ), The storage means 60 and the like.

The key input means 10 is a general key input device such as a keyboard and a mouse. The key input means 10 generates a key signal according to a key operation of a user who uses a tree structure document editor and outputs it to the control means 20.

The control means 20 controls the execution, storage, loading, etc. of the tree structure document editor, and collectively controls the document structure of the tree structure according to the key signal input from the key input means 10.

At this time, the control means 20, the size of the content corresponding to the logical output size of the entire node for the real-time coordinate changes according to the addition / deletion / movement and enlargement / reduction of each node by the operation of the user performing the tree search Keeps the memory field. That is, in order to quickly reflect the real-time coordinate variation of a large number of nodes having different sizes, each node maintains the screen visibility height reflecting the size of the lower node in real time in the form of a memory field, and displays on the screen of the node. The variable position starts from the node list of the top node and searches the top-down method to find the first node to be displayed on the screen, and sequentially starts the node to display in the next position starting from the first node according to the node association. This is to create a list of display nodes.

In more detail, the first node search method to be displayed on such a screen will be described in detail. First, the screen visibility height including the display height of the lower main / second node in the uppermost node group is cumulatively added to determine the number of nodes to be displayed. After the top node is confirmed, the bottom node group immediately following the top node is added cumulatively to determine the immediate node by accumulating the visual height, and then repeats this step to the bottom to complete the search for the node. Determine the display area of the node based on it (ie, the X coordinate is calculated taking into account the offset entered by the user and the basic option according to the level of the node, and the Y coordinate is the cumulatively added screen height, and the size of the node. Is embedded as its own information field.

In addition, the control unit 20 does not output all screens such as texts, pictures, videos, charts, and charts included in each node of the generated tree document, and searches only the resources of a specific node selected by the user by a tree search. To copy or reference.

In addition, when the corresponding resource included in each node of the tree document is not displayed on the screen, the control unit 20 releases the corresponding resource from the memory to optimize memory usage.

In addition, the control means 20 accumulatively accumulates the logical size of the node which is the size displayed when displayed on the screen, the screen size of the node which is the size output on the current screen, its screen size and the screen size of the lower nodes. Controls to record the data such as the node's own size, type, size that can be displayed on the screen, and whether to display the expansion, including the expanded size of the node in the file, and refers to this data when opening the file. Control to display

The tree document expresses each node type consisting of text, picture, video, chart, chart, etc. in a single field (integer or character), and stores the picture, video, external object in binary format or as a reference URL. Save, add / move / delete / modify without limiting each node's hierarchy, and adjust the size of the node being edited by dragging the outline displayed on the screen. In addition, * .tdoc is used as the extension of the tree document, but is not limited to this. Other extensions can be used, and the size of each node is linked with the size of text, picture, and video.

The user interface means 30 displays a document editor input screen on the screen under the control of the control means 20, and according to the user's function selection for inputting text, pictures, videos, diagrams, charts, 3D models, and the like. Displays an input form on the screen for editing the content.

The document management means 40 defines a tree structure composed of one or more top nodes and bottom main / sub nodes according to a user's operation, and creates a tree such as one or more top nodes and bottom main / sub nodes. Processes the data input of texts and charts / charts input on the node, or displays the specific pre-stored picture or video files or the editors to generate the tree document.

The output generation means 50 is responsible for outputting the tree structure document generated through the document management means 40.

The storage means 60 stores actual data such as pictures and videos used for document editing or a link thereof, and stores a tree structure document generated through the document management means 40.

Next, an embodiment of the tree structure document editing method according to the present invention configured as described above will be described in detail with reference to FIGS.

2 and 3 are flowcharts showing the operation process of the tree structure document editing method according to the present invention in detail, and FIGS. 4 to 8 are diagrams for explaining the use state of the tree structure document editor according to the present invention.

The editing method applied to the tree structure document editor according to the present invention will be briefly described as follows. The editing method presented herein is provided as an embodiment, and may vary depending on the system environment.

The tree structured document editor according to the present invention displays characters as much as a specified size when text is input through the keyboard in order to provide a text editing environment that is familiar to the user, and if the size exceeds the size, the text is continuously output on the next line.

Entering a new text node forms a new text node and prints it on the next line as the same sibling node, pressing Shift + Delete deletes the node, pressing the Backspace key when the cursor is at the beginning of the text node displays the top line. Merging with nodes, inserting / modifying / deleting / copying / cutting of characters is the same as a general text editor. If the text of a text node is blank, it indicates that it is blank except for the display icon.

In addition, unlike the general document, the tree structured document editor according to the present invention has a hierarchical content of a document, so that it is very easy to search for a corresponding resource. Navigate through the tree search and selectively copy or refer only to the required nodes for quick and easy document editing (e.g., enter the node position of the document into the text box and hit enter to insert the node into the current node editing position. Insert as child node, if the requested node is in the form of a folder, press Shift Enter key to copy to the infrastructure at once.

In addition, the tree structured document editor according to the present invention supports all the various data formats so that the user can easily create an optimal screen layout desired by the user, and can be recycled / reproduced anytime and anywhere by inputting a layered address of the node. It has a mass production structure of form documents, and all types of nodes are created by deriving base nodes with a specific output size. Therefore, it is easy to add / move / delete / modify without any restrictions between layers, providing a convenient hierarchical document environment. The size of the node being edited can be adjusted by dragging the node outline on the screen and the horizontal position can be specified by clicking the increase / decrease button on the tool.

The operation key of the tree structure document editor according to the present invention is summarized as follows.

Enter: Add a new text node consisting of the separated characters by separating the characters at the current node's character position.

Shift + Enter: add a child node

Shift + Left: go to parent node

Shift + Right: Move to the first node below

Shift + Delete: delete the current node

Shift + Insert: Add a new node (base node) to the child

Up: Move to the corresponding text position of the parent node in the current cursor

Down: Move to the character position of lower node in the current cursor

Ctrl + Right: expand the selection node

Ctrl + Left: collapse selected node

<When the character cursor is the insertion point>

Ctrl + C: Copy Node

Ctrl + V: Paste Node

Ctrl + X: Cut node

<When the character cursor selects the selected character>

Ctrl + C: Copy Character

Ctrl + V: Paste character

Ctrl + X: Cut character

Now, an embodiment of the tree structure document editing method according to the present invention according to the above-described editing method will be described in detail.

First, the control means 20 determines whether the tree structure document editor execution signal is input from the key input means 10 according to the user's operation (S10), and if the tree structure document editor execution signal is input, the user interface means 30. In step S20, a tree structure document input unit input screen including a tool menu for generating a tree document is displayed.

The control means 20 determines whether the user performs a key operation (for example, a mouse click) for generating a new document on the tree structure document input unit input screen (S30), and if the key operation for generating a new document is performed, the user The interface means 30 generates a node supporting the text (S40).

In the document management means 40, a user who creates a node for basic text input directly inputs text on the node, or a tool such as a picture, a video, a chart / chart, and an application extension data (ie, an external editor). It is determined whether one of the menus is selected (S50).

As a result of the determination, when the user directly inputs the text on the node using the keyboard or selects one of the tool menus such as a picture, a video, a chart / chart, and an application extension data, the document management means 40 determines that the user Records the text you input directly, or performs input processing such as pictures, videos, charts / charts, and application extension data, and creates nodes at the location according to the user's selection of the top node and the bottom node. After that, a tree document is generated by performing input processing such as text, picture, video, chart / chart and application program extended data (S60).

Referring to FIG. 3, the document management means 40 determines whether the user selects a text input, a picture input, a video input, a chart / chart, and an application extension data input on the newly created node. In operation S602, if the text is input, the text input by the corresponding user is directly input on the node (S604).

In addition, when the user selects the input of the picture file, the document management means 40 executes a folder window to allow the user to select the picture file stored in the storage means 60 (S606). It is determined whether the user who checks the folder window selects a specific picture file (S608). When the user selects a specific picture file, the corresponding picture file is displayed on the node according to the size (S610) (see FIG. 5).

In addition, if the user selects an external object input such as a video file as a result of the determination in step S602, the document management means 40 allows the user to select an external object such as a video file stored in the storage means 60. In operation S612, it is determined whether the user who checks the folder window selects a specific video file (eg, a movie file) (S614). When the user who checks the folder window selects a specific video file or the like, a module for executing the file is loaded into the memory (S616), and the playback process of the video file selected by the user on the node is performed (S618). (See Figure 6)

In addition, if the user selects input of the chart / chart and application extension data as a result of the determination in step S602, the document management means 40 displays the chart / chart and application extension data on the corresponding node (S620). In step S622, it is determined whether a key operation is performed to change the contents of the chart / chart and the application program extended data. As a result of the determination, when the key manipulation is performed to change the contents of the chart / chart and the application extension data, a table or a corresponding interface for data change is inserted into the document in a manner similar to the node expansion, or displayed on the screen in the form of a pop-up window. (S624), it is determined whether the user changes the data by inputting the data into the corresponding table or interface (S626), and when the data is changed, the user changes the data by applying the changed data to the chart / chart and application extension data. (S628). (See FIGS. 7 and 8)

After the user performs text input, picture input, video input, chart / chart, and application extension data input on a specific node as described above, the document management means 40 according to the user's operation, the top node or the bottom main / sub node. In step S630, when generation of the top node or the bottom main / sub node is selected, the node is generated at the location designated by the user, and then the above step S602 is repeated (S632).

Now, after performing input processing such as text, picture, video, chart / chart and application extension data input by the user through the above-described step S60, the control means 20 determines whether the user selects the end of the tree document work. Determining (that is, whether or not the user selects to save the tree document) (S70), if the end of the tree document operation is selected, saves the currently working tree document in the storage means 60 and ends the document editor (S80) If the tree document job termination is not selected, the above-described step S60 for generating a tree document is repeated. At this time, in the storage means 20, when the tree document currently being edited is stored, the logical size of the node, which is the size displayed when displayed on the screen, the screen size of the node, which is the size displayed on the current screen, and its screen size and lower portion. The user can record data such as the node's own size, type, size that can be displayed on the screen, and whether to display the expansion, including the expanded size of the node, which is the sum of the screen sizes of the nodes in the file. When loading later, refer to this data and display it on the screen. In other words, the tree document work state is reproduced as before.

On the other hand, if the user does not select the creation of a new document on the tree structure document editor as a result of the above-described step S30, the control means 20 determines whether the user selects a specific stored tree document (S90). When a specific tree document is stored in advance, the tree document stored in the storage means 60 is loaded and displayed on the screen through the user interface means 30 (S100).

After loading the tree document and displaying it on the screen, the document management means 40 determines whether the additional operation of the tree document is selected or the movement / deletion of the tree document is selected according to the user's operation that checked the tree document. (S110).

As a result of the determination, when the additional work of the tree document is selected according to the user's operation, the document management means 40 performs the step S60 and subsequent steps for generating the document, and moving / deleting the tree document is selected according to the user's operation. If so, the user processes the movement / deletion of the selected node (S120).

After performing the deletion / movement process of the tree document, the control means 20 determines whether the user selects the end of the moving / deleting operation of the tree document (that is, determines whether the user chooses to save the tree document) (S130). If the end of the move / delete operation of the tree document is selected, saves the currently working tree document in the storage means 60 and ends the document editor (S140), if the end of the move / delete operation of the tree document is not selected as described above Repeat after step S110.

As described above, according to the tree structure document editor and the document editing method of the present invention, objects of various sizes and data such as texts, pictures, videos, charts / charts, application extension data, etc., which are desired by the user, can be stored on a single document editor. By editing the structure, it is possible to mass-produce formatted form documents such as dictionaries, codes, project management, resumes, etc., and there is no need to use multiple edit windows, thereby making it easy to edit and manage data.

Herein, while the present invention has been described with reference to the preferred embodiments, those skilled in the art will variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below. And can be changed.
