Scaling and zoom
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: 开发者_如何学Pythonthe 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.
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.
