- This is the inset locking stuff needed for mathed --------------------
-
- an inset can simple call LockInset in it's edit call and *ONLY* in it's
- edit call.
- Inset::Edit() can only be called by the main lyx module.
-
- Then the inset may modify the menu's and/or iconbars.
-
- Unlocking is either done by LyX or the inset itself with a UnlockInset-call
-
- During the lock, all button and keyboard events will be modified
- and send to the inset through the following inset-features. Note that
- Inset::insetUnlock will be called from inside UnlockInset. It is meant
- to contain the code for restoring the menus and things like this.
-
-
- virtual void insetButtonPress(int x, int y, int button);
- virtual void insetButtonRelease(int x, int y, int button);
- virtual void insetKeyPress(XKeyEvent *ev);
- virtual void insetMotionNotify(int x, int y, int state);
- virtual void insetUnlock();
-
- If a inset wishes any redraw and/or update it just has to call
- UpdateInset(this).
- It's is completly irrelevant, where the inset is. UpdateInset will
- find it in any paragraph in any buffer.
- Of course the_locking_inset and the insets in the current paragraph/buffer
- are checked first, so no performance problem should occur.
-
- Hope that's ok for the beginning, Alejandro,
- sorry that I needed so much time,
-
