Problem Statement of Text Editor

Text editor mainly aims at developing an application that helps us in creating and editing text files. The application is more user-friendly and platform independent. The user can edit and manipulate the typed text to his satisfaction. Following gives a brief description about the features and the use cases developed in the project. This specification describes the project based on functionality and features. Each feature, along with its specification function and working are described in detail.

Create a file: This option allows user to create a new file and perform various functions on that file. When the user clicks on to the editor icon on the screen, the request is sent to the OS and it is processed by opening the editor screen on the desktop which allows the user to type the required text on the newly created file, edit and perform various operations on the same.

Open a file:

This option allows the users to open an already existing file. We should make sure that the file is already available in the harddisk of the system being used. The user inputs the name of the file using the keyboard or by selecting the required file in the dialog box. The filename is sent to the harddisk and if file is found ,the file is displayed on the editor.Now the file is ready for all text manipulations like cut,copy and paste.

Save a file:

This is an usual operation which is performed before closing the file. The contents of the file are saved at any specified location on the disk ,this option is enabled only if there is any file which is already opened.In the similar fashion the newly typed text can also be saved.

Close a file:

This option allows the required file to be closed. The file is saved before closing. This feature is enabled only when the file is opened.The specified file window is closed by using this option.

Cut the text:

Another option that can be enabled only when at least one file is opened. This option helps user to edit the text. Here the user has to select the particular text that is to be cut before performing this action. When the “cut” option is chose the selected text is saved in a separate location, say a clipboard and the text disappears from the place where it was originally found. Another function that compliments this is the “paste” option which makes use of the text that is saved in the clipboard.

Copy the text:

Very similar to the “Cut” option is the “Copy” option. Selected part of text is copied into a common location when the text is copied. This can be used only when at least one file is opened. The only difference is that the selected text remains on the screen even after copying the text.

Paste the text:

This option is enabled only when a “Cut” or “Copy” is already performed. It allows the user to insert text from the common location where the selected text is saved, into the current file. The advanced features that can be added to this project are word wrap, print a file, dictionary, spell check, changing the format , font size ,mail merge etc.
