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);`

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

I tried this in a test program and it worked:
```auto
size(400, 600,P3D);
surface.setResizable(true);
```
Check this [https://github.com/processing/processing/issues/3952](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
> [@VansiusProductions](#):
>
> How do i Set Window’s Minimum size when using the P2D renderer?
here is some sample code
```auto
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:
```auto
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:

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
