Code: Select all

/*! \brief Handle a mouse press on this trackContentObjectView.
 *
 *  Handles the various ways in which a trackContentObjectView can be
 *  used with a click of a mouse button.
 *
 *  * If our container supports rubber band selection then handle
 *    selection events.
 *  * or if shift-left button, add this object to the selection
 *  * or if ctrl-left button, start a drag-copy event
 *  * or if just plain left button, resize if we're resizeable
 *  * or if ctrl-middle button, mute the track content object
 *  * or if middle button, maybe delete the track content object.
 *
 * \param me The QMouseEvent to handle.
