How to start sketch fullscreen or windowed with v3.0 depending on start command ?

martinSteigermartinSteiger
edited December 2015 in Questions about Modes

There are 2 possibilities to start a sketch:

  • Sketch Run (Ctrl-R) run windowed

  • Sketch Present (Ctrl-Shift-R) run fullscreen

In case of sketch is started with 'Run' command, a window with defined size should be opened. e.g.: size(800, 480, P3D);

On the other hand, it should be startet fullscreen! e.g.: size(displayWidth, displayHeight, P3D);

This will result e.g. to this coding:

// fullScreen should become a global variable provided by Processing! 
boolean fullScreen = false; // true if started with Ctrl-Shift-R
                            // false if startet with Ctrl-R 
void setup()
{ if (fullScreen)
     size(displayWidth, displayHeight);  // start full screen
  if (!fullScreen)
    size(800, 480);                  // start windowed
}
void draw()
{ background(111);
  textSize(60);
  textAlign(CENTER, CENTER);
  text ("drawing size: " + width + "*" + height, width/2, height/2-60);
  text ("screen size: " + displayWidth + "*" + displayHeight, width/2, height/2+60);
}     // this example works with processing v2.2.1.

But with processing v3.0 it's not allowed to use size(x,y,mode) twice. See https://processing.org/reference/size_.html

Now some questions about this starting problem:

  • Can I get an information on how the sketch was started?

  • Is it possible to start a sketch with defined window size or fullscreen depending on the start command?

  • If mode=JavaScript, sketch should start with a defined window size. If mode=Android, sketch should always be started fullscreen. How can this be made?

ps. Some infos about it

    • I've found out a present mode solution for JAVA2D renderer! \m/
    • However even after many hours, can't tame P2D & P3D.
    • And new newcomer FX2D doesn't have present mode yet I'm afraid.
    • Even though only working correctly for JAVA2D, gonna post it here so some1 else might fix it.
    • Just call checkAndSetPresentMode() inside setup() once you've got size() set: :ar! 

    boolean checkAndSetPresentMode() {
  final PSurface surf = getSurface();
  final PGraphics graph = getGraphics();
  final boolean isPresentMode;

  if (graph.isGL()) {
    isPresentMode = ((PSurfaceJOGL) surf).pgl.presentMode();
    if (isPresentMode)  setSizePGLHack();
    return isPresentMode;
  }

  isPresentMode = displayWidth ==
    (graph instanceof processing.javafx.PGraphicsFX2D
    ? (int) ((javafx.scene.canvas.Canvas) surf.getNative()).getWidth()
    : ((processing.awt.PSurfaceAWT.SmoothCanvas) surf.getNative()).getFrame().getWidth());

  if (isPresentMode)  surf.setSize(displayWidth, displayHeight);
  return isPresentMode;
}

void setSizePGLHack() {
  final PSurface surf = getSurface();
  final PGraphics graph = getGraphics();
  final PGL gl = ((PSurfaceJOGL) surf).pgl;
  final java.lang.reflect.Field scr, present;

  gl.presentX = gl.presentY = 0;
  graph.setSize(displayWidth, displayHeight);

  try {
    (scr = PSurfaceJOGL.class.getDeclaredField("screenRect")).setAccessible(true);
    ((java.awt.Rectangle) scr.get(surf)).setBounds(0, 0, displayWidth, displayHeight);

    (present = PGL.class.getDeclaredField("presentMode")).setAccessible(true);
    present.setBoolean(gl, false);
    surf.setSize(displayWidth, displayHeight);
    present.setBoolean(gl, true);
  }

  catch (ReflectiveOperationException ex) {
    throw new RuntimeException(ex);
  }

  surf.setLocation(0, 0);
  surf.placeWindow(null, null);

  gl.presentX = gl.presentY = 0;
  graph.setSize(displayWidth, displayHeight);
}

    Thanx for your hint! You have to dig deep in the bowels of processing for that solution. Because processing v3.0 forbit double 'size()' and 'fullScreen()' usage, I think this topic can only be solved by the developer team of processing !

    Dear developers, please can you think about an easy to use solution for all users?

    I was checking your function and its working! Starting full screen mode switches to full screen, but e.g. calling surface.setSize(500,500); freezes the sketch (tested under Win-7 Pro SP1, processing v3.0 64 bit).

    I use this test frame:

        //-----------------------------------------------------
    boolean isFullScreen = false; // true if started with Ctrl-Shift-R
                                  // false if startet with Ctrl-R 
    void setup()
    {
      size(800, 480, P3D);
      // switch to full screen mode, if sketch was started in 'Present Mode' (Ctrl-Shift-R)
      isFullScreen = checkAndSetPresentMode();
      println ("display : " +width +"*" +height);
      if (!isFullScreen)
        surface.setResizable(true);  // v3.0 only!
    }  
    void draw()
    {
      background(0);
      text ("screen: " +displayWidth +"*" +displayHeight, 22, 40);
      if ((displayWidth == width) && (displayHeight == height))
        text ("started in fullscreen mode", 22, 70);
      else  
        text ("started in window mode", 22, 70);
      text ("resolution: " +width +"*" +height, 22, 100);
    }
    void keyPressed()
    {
      if (key == 'f') setSizePGLHack();  // switch to full screen
      if (key == 'w') surface.setSize(500,500);  // v3.0 only!
    }

    • I've warned you that only for JAVA2D renderer the hack is working right! :ar!
    • Also I was not thinking about switching presentMode on & off.
    • As requested, check whether sketch was run w/ CTRL+SHIFT+R presentMode or not.
    • If so, then setSize() it to displayWidth & displayHeight dimensions.

    Starting full screen mode switch to full screen, but than it freezes, only a black screen...

    It doesn't freeze for me! Rather erratic positioning behavior.
    Below my test case I was using to "develop" my hack: :P

    With this hack the sketch can be started full screen with the Ctrl-Shift-R command, but the moving circle is only visible, if it is located within the rectangle given bei the 'size(800, 480, P2D);' command on my PC (Win7).

  • martinSteigermartinSteiger

    At the end the answers of my questions are...

    Can I get an information on how the sketch was started?

    --> NO

    Is it possible to start a sketch with defined window size or fullscreen depending on the start command?

    --> YES, but drawing fails afterwards

    If mode=JavaScript, sketch should start with a defined window size. 
If mode=Android, sketch should always be started fullscreen. How can this be made?

    --> at the moment there is no JavaScript available :-(

    So I only can repeat my request of this requirements. Dear developers, please can you think about an easy to use solution for all users?
