I set a frame to initial value (500,700);

But I allow the user to resize it by draging the edges.

How can I continue to use this new size for all the other frames that wud come along??

and also as and when they start up again??

1. listen for ComponentEvents (add ComponentListener to Frame)
2. save new size in some sort of .ini file.

for example, this frame will be use most of the time.
The old frame is diposed by mainFrame.dispose() method

public Myapp {
.
.
.

mainFrame = new JFrame("This 1st frame");
mainFrame.setSize(700,580);
content=mainFrame.getContentPane();
content.setLayout(new BorderLayout());

if I resize to (800,700) ..   how can I get the resized 'size' and pass it to the next frame (which is actually previous.dispose(); Or rather how to use this new resized value thruout??

what is the syntax to get the new size?

// member
 Dimension lastSize = new Dimension (700, 800);
 
 // before disposing old frame save the size
 lastSize = frame.getSize();
 
 
 // after creating Frame - save the size
 frame.setSize(lastSize.width, lastSize.height);
