Disable drag of JFrame

Question

I want to ask how to make frame can not drag when the application is running?

And then how to disable maximize, minimize button (title bar)?

I'm using JFrame.

Answer 1

Just add the below line it removes the window decorations like close maximise and minimise(titlebar). This itself disables the dragging only with mouse events.

frame.setUndecorated(true);

Answer 2

You can use a JWindow instead of a JFrame. There is no title bar, so the user won't be able to move it.

setResizable(false);
setUndecorated(true);
getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG);
