Remarks

When this navigator is attached to the BaseViewer using its property Navigator, it is working in the following way:

  1. When the left button of the mouse is pressed down, it captures the mouse control.
  2. When control is captured and the mouse is moved, the selection rectangle is displayed and stretched.
  3. When the left button of the mouse is released, the control zooms the content so that the selected portion occupy as much control client area as aspect ratio allows.
