doubleclicking with columns

Is there a plan to release a control that has columns and accepts a 
doubleclick on a row?. Currently a wxformlist is the only control that 
accepts a doubleclick but it has no columns and a wxformgrid has columns but 
no doubleclick function.
I could set up a type that created 2 or more adjacent listboxes to look like 
columns and link them with functions but don't want to spend time doing this 
and can workaround it with an ongotfocus function or button if the future 
holds a doubleclick function for a grid row.
