I would like to observe changes of the viewport size:
genericRenderWindow.onResize(this.onRenderWindowResized) as vtkSubscription; onRenderWindowResized(obj: vtkObject) { console.log(obj); }
Why is the output always undefined? What am I missing here?
Because that method is called without any argument.
That’s understood, thank you. However, doesn’t this line imply that the callback is passed instance: vtkObject as an argument?
Yes, the typescript definition is wrong. Unless we want to fix the code to match the TS definition.
