    Thanks for that!

    I am just working on it.

    I have a problem that when using confirm the msgbox is not in the foreground but behind the main window

    I have an mcve where this error does NOT occur (not helpful I know)

    But how can I make sure the msgbox gets in the foreground and has the focus? It's in P3D by the way.

    Thanks a ton as always!

    Chrisir ;-)

  • ah, it's because of P3D

    this mcve shows it (sometimes)

    solution...?

    Sorry @Chrisir; but I've never tested it w/ other renderers yet. Just JAVA2D! ~:>

    This library simply invokes JOptionPane's static methods: showMessageDialog(), showConfirmDialog() & showInputDialog().

    Which respectively corresponds to JS' alert(), confirm() & prompt(). ~O)

    Therefore, that is simply a JOptionPane interaction glitch w/ Processing's OpenGL P3D renderer you've just found out AFAIK. :|

    As you can see, JOptionPane is a Swing/AWT class: 8-|
    import static javax.swing.JOptionPane.*;

    And almost n1 knows Processing doesn't behave that well when we use Swing/AWT classes. ^#(^

  • solution in P3D....?

  • edited March 14

    @Chrisir, can you check out whether this Inputs class behaves correctly for all Processing's renderers: :-?
    https://Gist.GitHub.com/GoToLoop/bba0c288aaeeb5ef9bb1

    Aside from its readBoolean() method which directly invokes JOptionPane::showConfirmDialog(), everything else relies on a JDialog instance created outta a customized JOptionPane: :-B

    protected static final JDialog dialog = new JOptionPane(panel, QUESTION_MESSAGE) {
      @Override public void selectInitialValue() {
        field.requestFocusInWindow();
      }
    }
    .createDialog(null, TITLE);
    

    Notice its @Override method invokes method requestFocusInWindow() over a JTextField object. L-)

    Whether that's enough to force Processing's P3D and other renderers to always behave correctly related to foreground placement is your task now. #:-S

    Good luck! B-)

  • thanks!!

  • Thanks, I couldn't get it to run

    Do I need this library?

    No library found for iadt.creative.Inputs Libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder.

    • Just to make sure, I've copied & pasted "Test.pde" into the 1st main tab.
    • Then created a 2nd tab named exactly as "Inputs.java", and pasted Gist's "Inputs.java" there.
    • Hit CTRL+R and it compiled & run as it should under 64-bit PDE 3.3.5.
    • Indeed a red warning "No library found for iadt.creative.Inputs" appeared.
    • Just ignore it! :\">

    I get similar warnings on some of my sketches that include local libraries which are not installed in the sketchbook libraries folder. The sketches still run fine.

    To remove the warnings you can (sometimes) also add the resource to sketchbook > libraries.

  • this works, I needed the class in test tab

    in the 2nd tab Inputs.java I had to comment out the package

    // package iadt.creative;
    

    I also receive huge bunch of warnings but it runs now in 2D

    I've turned off warnings & auto code complete since the very beginning of P3. >:)

    In the 2nd tab "Inputs.java" I had to comment out the package.

    If you really had to, you're highly probably running a very old P3 version! 8-X

  • I also receive huge bunch of warnings...

    only when I enter a false age by the way!

    If you really had to, you're highly probably running a very old P3 version!

    no, I just installed 3.3.7 to make it work... ;-)

    I'm still using PDE v3.3.5. And due to many folks reporting bugs for v3.3.6, I've decided to skip it completely. :-h

    I had high hopes for this latest v3.3.7. But after reading that huge list of warnings, I'm gonna hold on to v3.3.5 for a while again! :-\"

  • in P3D the InputBox is not in the foreground.

    Is there not a command for this...

    annoying...

  • edited March 18

    Problem is, both renderers P2D & P3D are OpenGL-based wrapped by JOGL bindings: :-B
    https://JogAmp.org/

    Up till PDE v3.0a5, JOGL was somehow embedded as a Java's Applet. ~O)

    But after that, Processing's PApplet class isn't a subclass of Java's Applet anymore. :-&

    So I've got no idea how to control which component gets the right to be foreground:
    JOptionPane's Swing or P3D's JOGL. :-<

    You can check its API if you wish though: ^#(^
    https://JogAmp.org/deployment/jogamp-next/javadoc/jogl/javadoc/index.html?overview-summary.html

  • I would rather report it as a bug....

    but thank you!

    I had other difficulties in P3D with receiving keys etc. ...
