Text Editor Program Create a graphical text editor program. The window should only consist of a scrollable text area. The user should have the menu options to create new files and open/save existing files. Your Text Editor’s window size should be 500 pixels wide and 500 pixels tall. How your Text Editor must look (This image has been cropped): • When the program first starts, the window’s text area should be empty. o You can place a text area directly on the frame for this program. o The text area will fill the entire window, so the initial height and width of the text area will not matter. • The text editor must have a menu bar containing a single File menu. • The File menu should have the options of New, Open, Save, and Exit. (See photos) o Menu items should have the mnemonics shown below as well. • When the user selects the New menu item, the text area should be cleared. • When the user selects the Open menu item, an open file chooser window should appear. o When the user selects their file, the contents of the file should be displayed in the text area. • When the user selects the Save menu item, a save file chooser window should appear. o When the user selects their file, the contents of the text area should be written to the file the user selected. • When the user selects the Exit menu item, the program should end. • The text area should be scrollable but have no word wrapping. Additional Image
Tips • After opening/reading an existing file, be sure to close it. If you leave it open, the user will be unable to overwrite the existing file if it wasn’t closed. • When reading a file, you can build a string that contains the contents of the file, then use that string to set the text area’s text.
