jdialog

Is there a way to set a dialog location relative to a JFrame ? I would like to center the dialog to the frame that houses my GUI, instead the dialog often appears in the center of the screen rather than within the GUI. Is there a way to set a location relative to another JFrame You can: pass JFrame as argument for JDialog.setLocationRelativeTo(Component c) set to desired Point from JFrame to JDialog.setLocation(Point p) EDIT all Swing code must be done on EventDispatchThread , meaning that setVisible(true) should be wrapped into invokeLater EDIT2 when using the JFrame as Component c I am

What is the difference between a JFrame and a JDialog ? Why can't we use setDefaultCloseOperation(JDialog.EXIT_ON_CLOSE); for a JDialog? JFrame is a normal window with its normal buttons (optionally) and decorations. JDialog on the other side does not have a maximize and minimize buttons and usually are created with JOptionPane static methods, and are better fit to make them modal (they block other components until they are closed). But both inherit from Window, so they share much functionality. camickr Why we can't use setDefaultCloseOperation(JDialog.HIDE_ON_CLOSE); for JDialog ? Sure you

I have a JFrame (undecorated) with a Glasspane. This Frame opens a JDialog (also undecorated and has also a glassPane) and hides itself (setVisible(false)). The Glasspanes are set with .setGlassPane(). The Dialog is opened with the Frame as owner. The GlassPane extends a JPanel and implements AWTEventListener. I use it for resizing the Frames and Dialogs, so it knows it's parent (the Frame/Dialog) - this is called "target". The Events inside the GlassPane are handled like this: public void eventDispatched(AWTEvent event) { if (target instanceof JFrame) { e = SwingUtilities.convertMouseEvent( (

This thread gives timeouts but no idle condition - Can I set a timer on a Java Swing JDialog box to close after a number of milliseconds Thanks!

I have a working JDialog and now I want to add scroll bars to it. The documentation is a bit confusing to me. Do I add the dialog to the JScrollPane or vice-versa? It seems like all the examples have a JPanel in the dialog and the panel is scrollable. I have a dialog that grows dynamically so I want the dialog itself to be scrollable. Can someone point me in the right direction? Reply to Andrew Thompson Thanks for the reply. I let the size be determined by the layout manager at this point.
