// Hide title bar and borders
d1.setUndecorated(true);
// Set background for dialog

// Set opacity

// Create a dialog with current frame as parent
// with title Simple Dialog

// d1 cannot be made active if d2 isn't closed
// this is theme behind setting a dialog modal
// default value is false
d2.setModal(true);
// Set size

// Set layout
d2.setLayout(new FlowLayout());
// Make it non resizable
d2.setResizable(false);
// Set d2 location relative to d1
// d2 appears at center of d1

// Add some components

// Show the dialog
d2.setVisible(true);
