    • getWindowHandle

      public long getWindowHandle()

    • getWindowContentScale

      public Vector2f getWindowContentScale(Vector2f store)
      Get the window content scale, for HiDPI support. The content scale is the ratio between the current DPI and the platform's default DPI. This is especially important for text and any UI elements. If the pixel dimensions of your UI scaled by this look appropriate on your machine then it should appear at a reasonable size on other machines regardless of their DPI and scaling settings. This relies on the system DPI and scaling settings being somewhat correct.
      Parameters:
      store - A vector2f to store the result
      Returns:
      The window content scale
