Project Proposal

Proposed project is a development of software which would store in file(s) images with their associated text and be able to retrieve that information from file(s) which, would be than displayed in picture viewer. The software should have GUI windows user interface. User should be able to navigate between stored pictures and be able to add description to them. As an addition should be included dropdown box with picture list selection for quick access.

For development of proposed software I will use Java programming language which support object orientated techniques needed for this project. I would include following components: Swing components to create GUI environment, Layout Managers which allow displaying all components in correct manner, FileWriter Class which provide file writing function and FileReader Class which provide file reading functions.

As assistance with development of proposed project, error handling and testing I will use Eclipse integrated development environment (IDE) software for Java.

Project Design

Record structure design

The record structure of proposed project will be held in JAVA folder. Inside this folder would be three folders: Images, Text, JavaRun.

Images folder would store all images which would be retrieved into the image viewer as an image files.

Text folder would store all description associated with corresponding picture as a text files.

JavaRun folder would store all java files which are needed to run software.

information


User interface components design

JFrame window in size 700 by 680 Menu bar set at the top of JFrame window include menu options. “File” menu

consist “Open in Paint” option, “Save” option and “Close” option. “Tools” menu include: “Font Colour” option which allows changing font colour in text area, “Look and Feel” submenu consisting two options for look of the application: “Nimbus” set as default and “Metal” as an optional. “Help” menu includes “About” option which consist text regarding use of application and Support details.

Image title which is stored in text file in first line. Image view is a JLabel area in size 640 by 360. Image view area is designed to display

chosen image from images folder Picture description is a editable JText Field located below image view. It consist text

related to displayed image which is stored in text file in text folder. Dropdown box allows searching for specific text and picture. Save is a JButton which allows saving changes made to the text in picture description

area. Navigation buttons under the picture description area are Jbuttons which are helping

with navigation between pictures, they function after pressing them from left are: go back to the first picture, go to previous picture, go to next picture and go back to the last picture.

26 Adding more images with related text to the folder

Displaying new pictures after clicking next button

Added images are not showing becouse the loop for list is limited to 10 images

No For loop need to be changed to new number of images every time, as future improvement recommend to adjust the loop structure so any number of elements can be displayed

b. Report on test scheduled for Image Viewer application

After completed test schedule that covers all of the program functionality I found following:

Regarding to tests 1-4, application is opening after double clicking on run.jar file. Application opens in the middle of the screen with all GUI elements displayed in designed places. First image in the folder is displayed correctly with related text. Welcome title is displayed for three seconds after which is changed automatically to current image title.

Closing application is working properly by using Close option or keyboard shortcut. Warning message is displayed and user is asked for close choice confirmation.

Test 5 - 10 and test 15: shows navigation buttons functionality and that application is reading correct files from correct folders in right sequence.

Next button is working correctly and clicking it, change image to the next image in the right order. Back button is working correctly and change current image to previous in the right order. As an exception handling method, message boxes are displayed when user reached last or first image.

First and Last buttons are working correctly by going accordingly to the first image in the folder and last image in the folder.

Tests 11 – 12 are showing correct display of combo box selected choices.

Tests 13 – 14 are proving that to every image selected correct text and title is displayed.


In tests 16 to 19 editing and saving option are tested. Selected text can be edited and saved into specified file in directory. Directory was not displaying current program path, so I modified code to open directory in the current program location which solved the issue. Even moving program to new location will still open correct path to the folder holding text files.

Test 20 shows that Open in Paint option is working correctly and selected image is open in Paint application.

Tests 21 – 23 are showing that additional features to change font colour or application theme are working correctly.

Test 24 shows that about.txt which holds help and support information is opening in notepad.

Test 25 is showing that tooltip help information are displayed correctly while hovering over objects with mouse.

Test 26 checks if program is scalable. Currently program displays 10 images, more images can be added for displaying but currently adjustment needs to be made in the List of images loop but this is not user friendly solution.

System evaluation

In conclusion, all tested features included in Image Viewer application are working correctly. Data is stored accurately in designed files: text(x).txt and images(x).jpg. Program is reading data from the file accurately and displays it in structured GUI environment. All elements are displayed in right place and correct order.

All menu options are working properly and correct functions are open after clicking selected option. All buttons are working properly and assigned functionality is working correctly. External program Paint and Notepad are opening as an option from main program.

Having options to change application look theme and font colour it provide option to personalize application accordingly to the user taste and make it more personal. Unfortunately the settings selected by user are lost after application is closed, so I would suggest as an future improvement to save changed settings by overriding current default settings which allows to reopen application with user preferred theme.


Handling exceptions are working accurate, by informing user about reaching beginning or end of the folder. “Try catch” exceptions implemented in the code are working correctly while opening text files or image files.

Current version of application is very rigid, it is possible to scale program by adding new images and texts but currently it is not user friendly. As an improvement, I would suggest creating a separate option for adding new images and text to the current Array List which would be more user friendly then current option which need adjusting the For loop counter “i” to the new number of files.
