I have spent near more two weeks to write this Notepad application. At this moment, I want to share with you.
I wonder that do you know the Notepad in Windows xp/7. If you have no idea, I am pleasure to display the Notepad
in Windows 7 with you, and it displays as below:
It has large future and simple interface, so does my Notepad!
Well, I will introduce my Notepad.
First, Let's look at the structure of the my Notepad application:
=================================================The structure of the PRoject:================================================= -src/main/java -com.b510.notepad -client -Client.java -common -Common.java -ui -AboutUI.java -FindManagerUI.java -FontManagerUI.java -FontSizeManagerUI.java -JUI.java -MainUI.java -NotepadUI.java -ReplaceManagerUI.java -SkinManagerUI.java -util -EditMenuUtil.java -FileMenuUtil.java -FormatMenuUtil.java -HelpMenuUtil.java -NotepadUtil.java -ViewMenuUtil.java -log4j.properties -lib -skin -substance-1.0.jar -pom.xml
=================================================Describe for all files: =================================================
-Client.java --> The entry of the notepad application. It contains the main method. -Common.java --> All constants in here. -AboutUI.java --> About notepad page. -FindManagerUI.java --> Find page. -FontManagerUI.java --> Font setting page. -FontSizeManagerUI.java --> Font sizt setting page. -JUI.java --> The parent class for the NotepadUI, It extends JFrame. -MainUI.java --> The main page of the notepad. -NotepadUI.java --> The parent class for the MainUI, It extends JUI and implements ActionListener. -ReplaceManagerUI.java --> Replace page. -SkinManagerUI.java --> Skin setting page. -EditMenuUtil.java --> Edit menu functions provider. -FileMenuUtil.java --> File menu functions provider. -FormatMenuUtil.java --> Format menu functions provider. -HelpMenuUtil.java --> Help menu functions provider. -NotepadUtil.java --> Common functions provider. -ViewMenuUtil.java --> View menu functions provider. -log4j.properties --> A properties for the log4j. -substance-1.0.jar --> substance dependency. -pom.xml --> pom.xml
=================================================How to add substance to your project build path?=================================================
NOTE: Your computer should install the Maven(apache-maven-3.2.2 is good choice) before running this project! There are TWO ways to provided.
1. Using eclipse tool to add the substance-1.0.jar to project build path. 1.1.Finding the substance-1.0.jar with the path "notepad/lib/skin/substance-1.0.jar". Right Click --> Build Path --> Add to Build Path. 1.2.Then open the opm.xml(with the path "notepad/pom.xml") Deleting the substance dependency: <dependency> <groupId>org.jvnet.substance</groupId> <artifactId>substance</artifactId> <version>1.0</version> </dependency>
2. Copy the substance-1.0.jar to your repository. 2.1.Finding the substance-1.0.jar with the path "notepad/lib/skin/substance-1.0.jar". Copying the substance-1.0.jar file to your repository. The default path of the repository is "${user.home}/.m2/repository/org/jvnet/substance/substance/1.0/substance-1.0.jar"
=================================================How to run notepad project?=================================================Using the eclipse tool and finding the Client.java file with the path "notepad/src/main/java/com/b510/notepad/client/Client.java".Right Click --> Run As --> Java Application
==================
Some UIs Show
==================
1. The Notepad Main UI
2. File Menu
3. Edit Menu
4. Format Menu
5. View Menu
6.Help Menu
7.Untitle Notepad
8. Open a File
9. About Notepad
10. Change Skin
