adjust-cursor

Gets a cursor to be used in the editor's display. If the return value is #f, a default cursor is used.

See also set-cursor.

• (send an-editor adjust-cursor event) -> cursor% object or #f
      event : mouse-event% object

  If an overriding cursor has been installed with set-cursor, then the installed cursor is returned.

  Otherwise, if the event is a dragging event, a snip in the editor has the focus, and the snip's adjust-cursor method returns a cursor, that cursor is returned.

  Otherwise, if the cursor is over a snip and the snip's adjust-cursor method returns a cursor, that cursor is returned.

  Otherwise, if a cursor has been installed with set-cursor, then the installed cursor is returned.

  Otherwise, if the cursor is over a clickback region in an editor, an arrow cursor is returned.

  Finally, if none of the above cases apply, a default cursor is returned. For a text editor, the default cursor is an I-beam. For a pasteboard editor, the default cursor is an arrow.
