  72    This is the inset locking stuff needed for mathed --------------------
  73
  74    an inset can simple call LockInset in it's edit call and *ONLY* in it's
  75    edit call.
  76    Inset::Edit() can only be called by the main lyx module.
  77
  78    Then the inset may modify the menu's and/or iconbars.
  79
  80    Unlocking is either done by LyX or the inset itself with a UnlockInset-call
  81
  82    During the lock, all button and keyboard events will be modified
  83    and send to the inset through the following inset-features. Note that
  84    Inset::InsetUnlock will be called from inside UnlockInset. It is meant
  85    to contain the code for restoring the menus and things like this.
  86
  87
  88    virtual void InsetButtonPress(int x, int y, int button);
  89    virtual void InsetButtonRelease(int x, int y, int button);
  90    virtual void InsetKeyPress(XKeyEvent *ev);
  91    virtual void InsetMotionNotify(int x, int y, int state);
  92    virtual void InsetUnlock();
  93
  94    If a inset wishes any redraw and/or update it just has to call
  95    UpdateInset(this).
  96    It's is completly irrelevant, where the inset is. UpdateInset will
  97    find it in any paragraph in any buffer.
  98    Of course the_locking_inset and the insets in the current paragraph/buffer
  99    are checked first, so no performance problem should occur.
 100
 101    Hope that's ok for the beginning, Alejandro,
 102    sorry that I needed so much time,
