get-dc

Returns either the drawing context into which the editor is displayed, or the context into which it is currently being drawn. When the editor is not embedded, the returned context is always the drawing content into which the editor is displayed. If the editor is not displayed, #f is returned.

The origin of the drawing context is also returned, translated into the local coordinates of the editor. For an embedded editor, the returned origin is reliable only while the editor is being drawn, or while it receives a mouse or keyboard event.

• (send an-editor-admin get-dc x y) -> dc<%> object or #f
      x = #f : boxed real number or #f
      y = #f : boxed real number or #f

  The x box is filled with the x-origin of the DC in editor coordinates, unless x is #f. The y box is filled with the y-origin of the DC in editor coordinates, unless y is #f.
