You have to use a prg named newcol.prg (for instance)
Define Class mycol as Column
** put all the column properties you need here. I show only two as an
example
Procedure init
this.width = 40
this.header1.caption ='New col'
endproc
EndDefine
You then instantiate it like so:
*form init
Set Procedure to newcol.prg additive
** add as many columns of the new class as you wish, in here I just add
four of the new class
local cN,cV
for k = 3 to 6 && I assume your grid has originally 2
columns
cN = alltrim(str(k))
thisform.grid1.Addobject('column'+cN,'mycol')
cV = 'thisform.grid1.column'+cN+'.visible = .t.'
&cV
endfor

Dear Vixens and Reynards:
How does one subclass Column and get it used?
According to Hacker's 6, this can not be done in the GUI, but I
code nearly everything. I can not find where to specify an
alternative Column class. If I have to explicitly instantiate the
columns, where/when/how do I do it?
Sincerely,
