My Notepad

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:

            -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.

=================================================
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?
