a) If you want to change the location of the message dialog box, use the following statements:
JOptionPane optionPane = new JOptionPane("Message");
JDialog dialog = optionPane.createDialog(JOptionPane.getRootFrame(), "Titre");
// Change location
dialog.setLocation(10, 10);
dialog.setVisible(true);
dialog.dispose();b) You're right, displaying a message to wait for the end of each move in the 3D view is probably not the best solution.
Miserably, the solution is not straightforward. The best solution would be to wait for an event that tells you that a move of the camera is finished in the 3D view, but this would oblige you to create and display a 3D view that would use the canvas3DPostRendered method I added for Canvas3D instances (see line 244 in HomeComponent for a real example).
If you capture images with Robot class (as I suppose you do), a simpler solution might be to include your calls to createScreenCapture in EventQueue invokeLater or invokeAndWait calls (the choice depends on the thread in which you run your video program).
final Robot robot = new Robot();
EventQueue.invokeLater(new Runnable() {
public void run() {
robot.createScreenCapture(...);
}
});c) I don't see any error in your code.
It looks almost the same as the one I used in VideoPanel.PhotoImageGenerator class. What exceptions do you get? Do you use multithreading?
