is there a way to set a maximum window size?
in particular I am trying to prevent content overflow by limiting the maximum window size
```auto
void setup() {
// initial window size
size(640, 360, P2D);
// allow window to be resized
surface.setResizable(true);
view.setup(P2D);
callOnSizeChanged(view, 720, 480);
verticalScrollBar.onOverflow = verticalScrollBar.new OverflowRunnable() {
@Override
public void run(int value) {
size(width, value, P2D);
}
};
horizontalScrollBar.onOverflow = horizontalScrollBar.new OverflowRunnable() {
@Override
public void run(int value) {
size(value, height, P2D);
}
};
verticalScrollBar.setup(P2D);
horizontalScrollBar.setup(P2D);
verticalScrollBar.document = view;
horizontalScrollBar.document = view;
}
```
but I get
```auto
When not using the PDE, size() can only be used inside settings().
Remove the size() method from setup(), and add the following:
public void settings() {
size(720, 472, "processing.opengl.PGraphics2D");
}
IllegalStateException: size() cannot be used here, see https://processing.org/reference/size_.html
```
at
```auto
horizontalScrollBar.onOverflow = horizontalScrollBar.new OverflowRunnable() {
@Override
public void run(int value) {
> size(value, height, P2D);
}
};
```

```auto
if(width > maxW) surface.setSize(maxW,height);
if(height > maxH) surface.setSize(width,maxH);
```

I already tried that but it just glitches when resizing with mouse

In a previous code, I ran this in the beginning of _draw()_ (this is for a minimum size, not a maximum, but the idea should be similar) :
```auto
GLWindow window = (GLWindow) getSurface().getNative();
final Dimension d = new Dimension(MIN_SIZE_X + 17, MIN_SIZE_Y + 40);
int xDist = max(window.getWidth(), d.width )-window.getWidth ();
int yDist = max(window.getHeight(), d.height)-window.getHeight();
window.setSize(max(window.getWidth(), d.width), max(window.getHeight(), d.height));
window.setPosition(window.getLocationOnScreen(null).getX() - xDist, window.getLocationOnScreen(null).getY() - yDist);
```
And although this works, It is quite glichy… The thing is, anyone correct me if I’m wrong, but I don’t think that P2D PGraphics handle well resizing in general… it’s like the sketch stops when resizing, and no call to _draw()_ is made…
Good luck !

wish there was a better way to set window size limits ☹
(and a way that actually works without having glitches such as the mouse overriding set size when resizable is true and the window is being resized)

just create an `int wdth and hght` (for width and height) and after you stop resizing the window, the variables are set to it. Because of that it won’t be buggy.
