[SOLVED] Chm

[Sarinam]

Hi All

How can i open a chm file through menu item.Plz help me..

Look at the Desktop (Desktop (Java Platform SE 6)) class, and you do know about ActionListeners? If not see How to Write an Action Listener (The Java™ Tutorials > Creating a GUI with JFC/Swing > Writing Event Listeners) and How to Use Menus (The Java™ Tutorials > Creating a GUI with JFC/Swing > Using Swing Components).

Google and especially the API docs (Java Platform SE 6) and Tutorials (The Java™ Tutorials) are your friends. Use them first.

Yes Sarinam, Google is the best place. You can find large number of examples on the web. At least try one of them and ask any question if you stuck with them.

More important thing is, pay attention on what masijade says.

Yes sir adding click event....

Did you read those two tutorials and the API docs for Desktop that I posted?

The last one shows you how to create menus and add ActionListeners to the Items.

The second one shows you how to write an ActionListener.

The first one (the API doc) shows you a class you can use to allow a system to "open" a "chm" file with the "default" program assigned to handle it.

So, write an ActionListener that calls desktop and attach it to your menu item.

That's it.

Can you give me some example code..

[masijade]

Post your attempt at it, and we will help you correct it, but we are not going to do it for you. Those tutorials have enough code snippets as it is, anyway. And a little Google searching, I can guarantee, will turn up a code snippit for Desktop.

Yep, shows your code where you stuck with and try to get our members help. I'm sure that too, you can easily find an example on the web related to your application.

    mi.addActionListener(this); 
    add(mi = new MenuItem("Close")); 
    mi.addActionListener(this); 
    add(mi = new MenuItem("Exit")); 
    mi.addActionListener(this); 
  } 
 
  public void actionPerformed(ActionEvent e) { 
    String item = e.getActionCommand(); 
    if (item.equals("Exit"))  
      mw.exit(); 
    else  
      System.out.println("Selected FileMenu " + item); 
  } 
} 
 
class HelpMenu extends Menu implements ActionListener { 
  MainWindow mw;  
  public HelpMenu(MainWindow m) { 
    super("Help"); 
    mw = m; 
    MenuItem mi; 
    add(mi = new MenuItem("Basics")); 
    mi.addActionListener(this); 
    add(mi = new MenuItem("Advanced")); 
    mi.addActionListener(this); 
    addSeparator(); 
    add(mi = new CheckboxMenuItem("Manual")); 
    mi.addActionListener(this); 
   
    Menu subMenu = new Menu("Miscellaneous"); 
    subMenu.add(mi = new MenuItem("Help")); 
    mi.addActionListener(this); 
    subMenu.add(mi = new MenuItem("Other Option")); 
    mi.addActionListener(this); 
    add(subMenu); 
  } 
  
  public void actionPerformed(ActionEvent e) { 
    String item = e.getActionCommand(); 
    if (item.equals("Basics")) 
      System.out.println("Basics"); 
    else if (item.equals("Help"))  
      System.out.println("Help"); 
  } 
}

Sir here how can i add chm..

[masijade]

When the "actionCommand" equals "Open", use JFileChooser to have the user select the file then call Desktop.open(file). What is so hard here?

See, after few attempts you got the things. Now what you have to do is on menu item click event, do the same process. Do you know how to add events to menu items?

import java.awt.*;

public class MainMenu 
{
	Frame   m_Frame        = null;
	boolean m_fInitialized = false;

	

	MenuBar mb;
	


	MenuItem MN_EXIT;	
	Menu m3;	
	
	

	
	Menu m8;
	MenuItem ID_HELP_ABOUT;	
	MenuItem ID_HELP_TOPICS;
	
	
	
	// Constructor
	//--------------------------------------------------------------------------
	public MainMenu (Frame frame)
	{
		m_Frame = frame;
	}

	
	// Initialization.
	//--------------------------------------------------------------------------
	public boolean CreateMenu()
	{
		// Can only init controls once
		//----------------------------------------------------------------------
		if (m_fInitialized || m_Frame == null)
			return false;

		// Create menubar and attach to the frame
		//----------------------------------------------------------------------
		mb = new MenuBar();
		m_Frame.setMenuBar(mb);

		// Create menu and menu items and assign to menubar
		//----------------------------------------------------------------------
	//
	//		MN_EXIT = new MenuItem("Exit");
	
			m3 = new Menu("Settings");
			mb.add(m3);
				
		
	        
	        
	        MN_EXIT = new MenuItem("Exit");
			m3.add(MN_EXIT);
			
			
		
			
		
		m8 = new Menu("Help");
		mb.add(m8);
		ID_HELP_TOPICS=new MenuItem("Help Topics");
		m8.add(ID_HELP_TOPICS);
	
		ID_HELP_ABOUT = new MenuItem("About");
		m8.add(ID_HELP_ABOUT);
		
		
	
		
		
			
		m_fInitialized = true;
		 
		return true;
