Window.getDefaultSize

void getDefaultSize(out int width, out int height)

Gets the default size of the window.

A value of 0 for the width or height indicates that a default size has not been explicitly set for that dimension, so the “natural” size of the window will be used.

This function is the recommended way for saving window state across restarts of applications.

Parameters

widthlocation to store the default width
heightlocation to store the default height
