wxGrid navigation and column tooltips

Hi,

I have a wx.Grid that I'm using for as a spreadsheet in one
of my
applications. I would like to override the grid cell
editor's arrow key
navigation so that when I press one of the keys, it will
navigate away
from the cell I am currently editing, like MS Excel does.
While I can
successfully catch the keycodes for the buttons when I am
not editing a
cell, they seem to get eaten once I actually activate the
editor. Is there
a way to do this?

Also, one of my users asked if I could put pop-up tooltips
on the column
name when moused over. I can't find anything about
mouse-over events. I
did find this excellent tutorial on grid cell tooltips:
http://wiki.
wxpython.org/wxGrid_ToolTips

Unfortunately, it doesn't apply to my case. Any help one
these two issues
would be appreciated.

I am using wxPython 2.8.4, Python 2.4 on Windows XP SP2.
Thanks!

Keep in mind that when the cell editor is shown that there
is another 
widget there, and so the grid itself doses not have the
keyboard focus 
anymore, and so it will not be getting the key events.  You
can however 
bind your own key handler to the cell editor widget and take
care of 
things there.  Bind a handler for the
EVT_GRID_EDITOR_CREATED event and 
in the handler you can use event.GetControl() to get a
reference to the 
widget.

You can intercept the mouse events for the 
theGrid.GetGridColLabelWindow() and show a tip window if you
sense that 
the mouse is hovering.  Be sure to call event.Skip() so the
default 
event handlers in the grid will still be called.
