Comprehension problem...

Hi everybody! I still have the same problem… :-\

I know that’s a nooby problem, but nobody understand me…

So, I will explain you very simply…

I have 3 classes: A main, a frame and a Button class.

The main lauch the frame class with “frame f = new frame();”

The frame class create a frame with :


public class frame extends Button implements MouseListener, ActionListener{


	JFrame frame;



	
	public frame (){
		
		JPanel contenu;


		frame = new JFrame("Doode - Jeu");
		frame.setLayout(null);
		
		contenu = new JPanel();
				
		contenu.addMouseListener(this);
		
		 frame.setContentPane(contenu); 
		 

			frame.setSize(400,400);
			frame.setResizable(false);
			frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
			frame.setVisible(true); 

Button b = new Button();
 
}}

The Button class create a JButton by :

public int CoorX=0;
public int CoorY=0;
JPanel contenu;
public JButton Doode = new JButton ("",new ImageIcon("DoodeImages/vert.gif"));



public Button(){
		System.out.print("doode crée ");

		Doode.setBounds(15,15,50,50);
		Doode.setFocusPainted(false);
		Doode.setBorderPainted(false);                  
		Doode.setContentAreaFilled(false);
		Doode.addMouseListener(this);
		Doode.setVisible(true);

}

public void mouseClicked(MouseEvent arg0) {
	// TODO Auto-generated method stub
	
}



public void mouseEntered(MouseEvent arg0) {
	// TODO Auto-generated method stub
	
}




public void mouseExited(MouseEvent arg0) {
	// TODO Auto-generated method stub
	
}



public void mousePressed(MouseEvent arg0) {
	// TODO Auto-generated method stub
	
}



public void mouseReleased(MouseEvent f) {
	Object source = f.getSource();	

	if(SwingUtilities.isRightMouseButton(f)) {

		CoorX=f.getX();
		CoorY=f.getY();
 }

}}

I want that everytime I put the line “Button v = new Button();” in the frame class, it show me a new button…

I hope this time you understood me :confused:

To show a button in a JPanel you should add it to the panel .

in your case, you should add this call :



Button b = new Button();

// add the button to a panel
contenu.add (b.Doode);

that’s a pretty bad design though. If you want your button to be a special kind of JButton, you should extend JButton .

#3

I already showed you how to do this…

I thought I understood what you wanted(cause you said I was right).

you want a new one for every new time you make a doode right??

what was wrong with the code I gave you.

help me help you,
h3ckboy

EDIT:
hmm, I looked at the other thread, and saw you were asking…

for starters, why did you make a new thread?

second, you completely disregarded the code I gave you… I didnt see anything static, so I solved your problem, it just seems you dont want the solution I gave you?

#4

h3ckboy, the code you gave me worked fine for define a new name for each button, but, these buttons don’t appear in my frame ^^

THe game don’t crash, but Jbutton “DoodeVert” aren’t in the frame… I tried to solve this problem by lots of way, and now, my code is crap and I think I have regressed… :-\

#5

kk, thank you, if you had just said something I could have taken a look ;).

I will take another look now to see if I missed something.

#6

well, I noticed some pretty deep design flaws in you code.

for starters, I couldnt find DoodeVerta declared anywhere, I did find DoodeVert, but not a DoodeVerta…

that would be an issue.

I will try and get something working from your code.

#7

It will NOT appear if you don’t add it to the panel or the jframe. They way it is right you just create a button instance, and that’s it . You habe to add it to the pane, so the pane renderizes it .

By the way, you should play a little more with basic swing API before starting to build your own customized stuff .

#8

The problem is your design. Have you worked through any of the Java Tutorial series?
