how to get pop up windows from java ...

thanks in advance

 

[Eraserhead]

like sheets? Or just like windows pop up windows? And what software are you using to make the GUI? Swing? Ant?

I don't know the answer to this question, just the answers should help others who know about Java GUI's to help you.

Here's a splash screen. Displays for about 5 seconds and goes away.

// Java Application sample to display a splash screen.

public class JavaPopup extends javax.swing.JWindow {

	private int duration ; 
	
	public JavaPopup(int d) { 
		duration = d ; 
	} 
	
	void ShowSplash(String text) { 
		
		javax.swing.JPanel content = (javax.swing.JPanel)getContentPane() ; 	
		content.setBackground(java.awt.Color.blue) ; 
		
		// Set the window's bounds & center the window 
		int width = 700 ; 
		int height = 200 ; 
		java.awt.Dimension screen = java.awt.Toolkit.getDefaultToolkit().getScreenSize() ; 
		int x = (screen.width-width) / 2 ; 
		int y = (screen.height - height) / 2 ; 
		setBounds(x,y,width,height) ; 
		
		javax.swing.JLabel myLabel   = new javax.swing.JLabel(text, javax.swing.JLabel.CENTER) ; 
		myLabel.setFont(new java.awt.Font("Courier" , java.awt.Font.BOLD,60)) ; 
		
		content.add(myLabel, java.awt.BorderLayout.CENTER ) ; 
		content.setBorder(javax.swing.BorderFactory.createLineBorder(new java.awt.Color(3,30,105,64),5) ); 
	
		setVisible(true) ;    // Display it 
		
		try { 
			Thread.sleep(duration) ;    // Wait a little while 
		}
		catch (Exception e) {}         // ignore any errors 
	} 
	
	void showSplashAndExit() { 
		ShowSplash("JAVA POPUP SCREEN") ; 
		System.exit(0) ; 
	} 
	
	public static void main(String[] args) { 
		JavaPopup splash = new JavaPopup(5000) ;  // 1000 = 1 second 
		splash.showSplashAndExit() ; 
	}
}
