Set Window's Minimum size when using P2D

VansiusProductions · June 23, 2018, 11:44pm

Hi,

How do i Set Window’s Minimum size when using the P2D renderer? I know for the default Java renderer I would do this:

PSurfaceAWT.SmoothCanvas sc = (PSurfaceAWT.SmoothCanvas) getSurface().getNative();
JFrame jf = (JFrame) sc.getFrame();
jf.setMinimumSize(new Dimension(1600, 900));

But the code above will not work when I use the P2D renderer. What will I need to do in this case? Any help would be appreciated!

I don’t know how to do this off the top of my head, but if I were trying to figure it out I would take a look at the error message you’re getting: they’ll tell you the classes that are actually being used. I’d also look through the Processing source code to see what’s going on inside the P2D renderer to know how to get to the underlying window.

Dunno either! But you should start your search here methinks:
https://JogAmp.org/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/newt/Window.html

import com.jogamp.newt.Window;
Window window;

void setup() {
  size(800, 600, P2D);
  window = (Window) getSurface().getNative();
  println(window);
}

Thanks for the useful link. I wrote a few lines of code to test this but I can’t even resize the windows itself. In my code I already did surface.setResizable(true). Doing window.setResizable(true) gives me the following error:

I don’t know what is happening here .

According to your original post:

You’ve seemed interested in setting minimum size only, not programmatically resizing the window directly!

If it is just the latter now, the class PSurface already got a setSize() method:
getSurface().setSize(width>>1, height>>1);

VansiusProductions · June 24, 2018, 1:16am

Oh, I meant resizing the window manually, not programmatically.

kfrajer · June 24, 2018, 2:49am

I tried this in a test program and it worked:

  size(400, 600,P3D);
  surface.setResizable(true);

Check this https://github.com/processing/processing/issues/3952

The only trick for me on a Win OS is that the mouse pointer does not change when it hovers on the edge of the window. However, if I click right at the edge and I drag the mouse, the window’s size adjusts to a new size.

Hi there - I’d like to resurrect this old post as the original question was not really addressed

here is some sample code

import processing.awt.PSurfaceAWT.SmoothCanvas;
import javax.swing.JFrame;
import java.awt.Dimension;

final static int minWidth=300;
final static int minHeight=300;

void settings() {
  size(500, 500); // will work
  // size(500, 500, P2D); // will fail @build time: ClassCastException: com.jogamp.newt.opengl.GLWindow cannot be cast to processing.awt.PSurfaceAWT$SmoothCanvas
}

void setup() {
  surface.setResizable(true);
  surface.setTitle("Testing Resize");
  surface.setLocation(10, 10);

  SmoothCanvas sc = (SmoothCanvas) getSurface().getNative();
  JFrame jf = (JFrame) sc.getFrame();
  jf.setMinimumSize(new Dimension(minWidth, minHeight));
}

void draw() {
  if ((width <= minWidth) && (height <= minHeight)) background(0xFFFF0000);
  else background(0xFF0000FF);
}

when building with size(500, 500); all is fine, but if I switch to size(500, 500, P2D); it will fail with

ClassCastException: com.jogamp.newt.opengl.GLWindow cannot be cast to processing.awt.PSurfaceAWT$SmoothCanvas

this is pretty self explanatory, clearly the window is no longer of the same type and we have a * com.jogamp.newt.opengl.GLWindow* but looking at its documentation I did not find anything related to setting a minimum size.

any hint appreciated if you got this to work.

thanks

Jay.

Get the window like this:

import com.jogamp.newt.opengl.GLWindow;

window = (GLWindow) surface.getNative();
window.setResizable(true);

Then at the top of draw(), include something like this:

window.setSize(max(window.getWidth(), minWidth), max(window.getHeight(), minHeight));

… as there doesn’t seem to be a way to set minimum dimensions on the window object:

jay_m · November 6, 2020, 11:29am

Thanks for the answer and confirming it does not seem to be a way to set minimum dimensions. I was just in denial that in 2020 there would be a package with such a missing feature…

So, yes, feels like that’s last resort solution. it is ugly when resizing compared to the behavior you get without P2D but…

thx again
