[solved]-Think Gui Layout Put Together Somewhat Correctly Feel Free Change Completely Far Need Use Q39082852
I think the GUI layout has been put together somewhat correctly,but feel free to change it completely. This is what I have so far.You do not need to use it! Thank you!

Pre-majors are placed into the Area of Interest (AOI) program and to be eligible for the degree, they must be admitted to and declare the major. The requirements and application process for matriculation are detailed below. Students admitted to other programs within the College of Engineering and Applied Science (CEAS) follow the same admissions process as students in the A0I program. Students in programs outside of CEAS (non-CEAS students) and double major applicants MUST apply for admission to the degree program following a separate process, outlined below.

Override the method Application.start to create and add all the GUI elements shown in the screen shot above. A suggestion: use a GridPane to lay out the GUI components. The large box in the middle is a TextArea. On the bottom of the screen there are two Label components: one showing the number of words and characters in the text area, and a second one that shows how many seconds have elapsed since the user last saved a file Y Part II: Loading a File (6 points) Add event-handling code for the “Load File” button and its associated TextField so that the user can load the file with the name provided in the text field and display its contents in the text area for editing. If you are using IntelliJ to implement this assignment, place your input text file in the top directory of your Intelli project (perhaps you called it “CSE 114”) Use an Alert Dialog to show an informative error message if a problem is encountered while reading the file. The only problem your are likely to encounter is that the user entered an invalid filename.

If you are using IntelliJ to implement this assignment, your output text file will be saved in the top directory of your Intelli project (perhaps you called it “CSE 114”) Use an Alert Dialog to show an informative error message if a problem is encountered while writing the file.

To Lower To Upper To Title Case Find Replace with Replace All # words : 115 # chars : 736 Seconds since last save: 30 OK Part IV: Change Text Area Contents to Lowercase (5 points) Add event-handling code to the “To Lower” button so that the contents of the text area are changed into lowercase Spaces, punctuation marks, digits and other non-letter characters should remain unchanged. No file reading or writing takes place as a result of pressing this button Part V: Change Text Area Contents to Uppercase (5 points) Add event-handling code to the “To Upper” button so that the contents of the text area are changed into uppercase Spaces, punctuation marks, digits and other non-letter characters should remain unchanged. No file reading or writing takes place as a result of pressing this button. Part VI: Change Text Area Contents to Title Case (5 points) Add event-handling code to the “To Upper” button so that the contents of the text area are changed into title case That is, given a word, change the leftmost character to uppercase (if that character is a letter) and all other letters in the word to lowercase. A “word” is defined as a group of characters that immediately follow one or more spaces. Also be sure to properly capitalize the first word in the text area, which is unlikely to have a space in front of it. Spaces, punctuation marks, digits and other non-letter characters should remain unchanged. No file reading or writing takes place as a result of pressing this button Part VII: Find and Replace Text (5 points) Add event-handling to the “Replace All” button so that the program searches through the text area for the text given in the “Find” text field and replaces it with the text given in the “Replace with” text field. If the “Find” text field is left blank then pressing this button should have no effect on the contents of the text area. No file reading or writing takes place as a result of pressing this button Part VIII: Display File Statistics (6 points) In the lower-left comer of the window create a Label that displays the number of words and characters in the text area. The definition of a “word” is given in Part VI. The contents of this label are updated with each key press inside the text area. You are not required to show the line over the label as shown in the screen shot above, but if you want to incorporate it you will need to learn a little about JavaFX CSS. Part IX: Seconds Elapsed Since Last Save (6 points) In the lower-right corner of the window create a Label that displays the number of seconds that have elapsed since the user successfully saved the contents of the text area into a text file. The easiest way to accomplish this is to use a Timeline object. Have your timer update the contents of the label every 1000 milliseconds (i.e., every 1 second). You are not required to show the line over the label as shown in the screen shot above, but if you want to incorporate it you will need to learn a little about JavaFX CSS.
