I have just written a program in Netbeans that moves/copies/deletes files, and I wanted to give it a "diagnostic mode" where information about selected files, folders, variables, etc is displayed in a Text Area. Now, I could set this to only be visible when the "diagnostic mode" toggle is selected, but I think it would look awesome if the text area started behind the program, and "slid" out from behind the JFrame when the button is toggled. Is there any way to do this?
Thanks! -Sean
Here is some starter code for you. This will right-slide a panel of just about any content type. Tweak as necessary. Add error checking and exception handling.
Tester:
static public void main(final String[] args) throws Exception {
SwingUtilities.invokeAndWait(new Runnable() {
@Override
public void run() {
final JPanel slider = new JPanel();
slider.setLayout(new FlowLayout());
slider.setBackground(Color.RED);
slider.add(new JButton("test"));
slider.add(new JButton("test"));
slider.add(new JTree());
slider.add(new JButton("test"));
slider.add(new JButton("test"));
final CpfJFrame42 cpfJFrame42 = new CpfJFrame42(slider, 250, 250);
cpfJFrame42.slide(CpfJFrame42.CLOSE);
cpfJFrame42.setSize(300, 300);
cpfJFrame42.setLocationRelativeTo(null);
cpfJFrame42.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
cpfJFrame42.setVisible(true);
}
});
}
Use GAP & MIN to adjust spacing from JFrame and closed size.
The impl is a little long...it uses a fixed slide speed but that's one the tweaks you can make ( fixed FPS is better ).
