Hi,
I use a grid as a display as well as data structure: there is information in
that grid that I wish to hide from the user ... one of them is a password
column.
I tried to change the column size to 0 without success ... is there a way to
hide that infomation (ex: even seeing stars on the grid cells would be fine).
Thanks,
Philippe

Store the information however you want, set up the grid to be virtual,
and override the GetValue() method to return something like '********'
on the password column.

So I should derive from the grid ? right now it is just another widget in a
panel.

The grid protects cols and rows from being resized to zero by the user in order to protect against their losing the ability to size it larger again. If you want to programatically set the size to zero you can do so, but first you need to call SetColMinimalWidth and set the min width to zero.
is there a way to hide that infomation (ex: even seeing stars on the grid cells would be fine).
You can use a custom renderer for that col that just draw stars, but if you want it to not be shown at all then the best thing is to separate your model (the data) from the view (the grid window). Put your data in some other structure and then use a class derived from wx.grid.PyGridTableBase that provides the data elements to the grid on demand. Then you can either just not provide that column at all, or provide "*****" or whatever. See the samples in the demo that use a grid table for an example.

Why would you include a column that is essentially hidden? What
information are you giving the user? My advice is to not display the
password at all in the grid.
