Scaling and zoom

Question

I need to implement zoom for a JDesktopPane contained in a JScrollPane. I have had prior success zooming by overriding the paintComponent(...) method and calling scale(double,double).

This is not working properly: the JInternalFrame's and JPanel's scale as intended, but the MouseListener's for the JLabel's and such register at the pre-scaled locations. What can I do? Thank you for reading.

Answer 1

ScaledPanel shows how to scale mouse coordinates using explicit transformation methods: scaleX, scaleY, unScaleX and unScaleY. Alternatively, you can use an inverse transformation, as shown here.
