Java Swing inactive button for window close

I am trying to create a gui using swing. I have a main frame and I want it to only show the x button at the top right corner. I would also like to make this button impossible to press if certain conditions are met. I did some search on google and on java's website but I couldn't find any functions related to these two tasks. Any small pieces of code or links to tutorials or apis are welcome.

I want the button to be there. I don't want the window to close (which I can do with the setDefaultCloseOperation) and also I'm trying to find a way to be able to make the button look greyed out and not allow it to execute the animation of getting pressed in when I click on it. I want it to be there but grey and totally non responsive.

maybe myFrame.setResizable(false); and all of Events for this Button you can hande this way

EDIT:

window's decorations coming from Native OS, and then you have this four options as follows

  • full decorated (JFrame) minimize/maximize/close Button

  • only close Button JDialog and JFrame#setResiziable(false)

  • undecorated, then there missed minimize/maximize/close Button(a) and toolBar (that came from Native OS) too

  • undecorated Top-level Container with JPanel (with GradientPaint simulated real ToolBar) contains JButton with Char X (could be enabled once time or another time disabled as you want)

You can use a JDialog it just have got the X button

JDialog

And with dialog.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);
you can disable the close button.

With dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
you can enable the close button

You didn't search very far. See http://download.oracle.com/javase/6/docs/api/javax/swing/JFrame.html#setDefaultCloseOperation%28int%29. Passing DO_NOTHING_ON_CLOSE to this method will forbid the frame to be closed via the default close button.

You can specify what you want to happen when close button is pressed on your Frame. If you want it to do nothing, then:

frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
