swing hide cursor

It appears that the
Cursor class does not have a "blank"cursor to begin with, so one could define a new "blank"cursor using the
Toolkit.createCustomCursor method.
Here's one way I've tried which seems to work:
 

// Transparent 16 x 16 pixel cursor image. BufferedImage cursorImg = new BufferedImage(16, 16, BufferedImage.TYPE_INT_ARGB); // Create a new blank cursor. Cursor blankCursor = Toolkit.getDefaultToolkit().createCustomCursor(     cursorImg, new Point(0, 0), "blank cursor"); // Set the blank cursor to the JFrame. mainJFrame.getContentPane().setCursor(blankCursor); 

 
Edit
Regarding the comment about everything inside the JFrame ending up without a cursor, it seems that the Component s which are contained in the JFrame will end up inheriting the cursor of the container (the JFrame ), so if it is a requirement to have a certain Component have the cursor appear, one would have to manually set the desired cursor.
For example, if there is a JPanel contained in the JFrame , then one could set the cursor of that JPanel to the system's default using the Cursor.getDefaultCursor method:

JPanel p = ... // Sets the JPanel's cursor to the system default. p.setCursor(Cursor.getDefaultCursor());
