Java Basics Using Qt Jambi Tutorial

How To Launch The Application?

1. Create an empty file called Main.java where your Ui_helloWorldMainWindow.java resides.

2. Copy and paste the source code:

package helloworld; import com.trolltech.qt.gui.*; import helloworld.*; /** * * @author jun */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here QApplication.initialize(args); QMainWindow window = new QMainWindow(); Ui_helloWorldMainWindow ui = new Ui_helloWorldMainWindow(); ui.setupUi(window); window.show(); QApplication.exec(); } }

Note: Your Ui_helloWorldMainWindow.java must contain: package helloworld in the first line of the source code.

3. Create the Manifest.txt file:

Note: Manifest file should contain the libraries needed and should have a new line or carriage return after the last line.

Manifest-Version: 1.0 Ant-Version: Apache Ant 1.7.0 Created-By: 10.0-b22 (Sun Microsystems Inc.) Main-Class: helloworld.Main Class-Path: /path/to/qtjambi-linux32-gpl-4.4.3_01/qtjambi-4.4.3_01.jar /path/to/qtjambi-linux32-gpl-4.4.3_01/qtjambi-linux32-gcc-4.4.3_01.jar X-COMMENT: Main-Class will be added automatically by build

4. Make the JAR file:

   Create a directory inside your source folder according to the package name. Then, put the *.class files inside the folder.

$javac cfm [package name].jar Manifest.txt [source/folder]/*.class $javac cfm helloworld/helloworld.jar Manifest.txt helloworld/*.class

The source folder must be the package name: “helloworld”

5. Run the JAR file:

$java -jar Main.jar

Or,

$java -Djava.library.path=[/path/to/qtjambi/lib/]:[/path/to/qtjambi-gcc/jar] -jar [/path/to/jar]

Note: Use this if haven't included the Manifest.txt file when running JAR files created using NetBeans.
