set-label in message%

Sets a window's label. The window's natural minimum size might be different after the label is changed, but the window's minimum size is not recomputed.

See get-label for more information.

• (send a-message set-label label) -> void
     label : bitmap% object

  Sets the bitmap label for a bitmap message. Since label is a bitmap, the bitmap must be valid (see ok? in bitmap%) and not installed in a bitmap-dc% object; otherwise, an exn:application:mismatch exception is raised. The bitmap label is installed only if the control was originally created with a bitmap label.

  
  

• (send a-message set-label l) -> void
     l : string (up to 200 characters)

  If the window was not created with a label, or if the window was created with a non-string label, l is ignored.
