Something about the output data.

Hi all,
I want to do some improvement to the output data.
When execute a query, if one column of the result data is something like
text or large varchar or xml, the output can't show all of them, it's not
very convenient for user to check the data.
Like MSSQL, when the result column is an xml type, it show as a hyperlink,
and one can click it and show a new window which contains the whole text.
I want to improve the pgadmin just like the MSSQL.
But I don't obtain much knowledge about the wxWidgets, so I want to asking
for help.

Is there any method to show the content of the wxGrid as hyperlink, and is
there any eventhandler of wxGrid to process the click of it's content.
Wish someone could help me~

Thanks a lot! Very appreciate your help~~~
