java - 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);
