Your are right ; I just made a new stack with a data grid "dGrid"
and a field "source"
created the columns manually in the inspector (col 1, col 2 etc)
In the field, the first tab delimited line includes the names for
the columns.
Then
set the pFirstLineContainsHeaders of grp "dGrid" to true -- or,
yes, put true into pFirstLineContainsHeaders as well
put fld "source" into tData
set the dgText ["pFirstLineContainsHeaders"] of group "Dgrid" to
tData
does not work as expected : the columns names keep being "Col 1,
Col 2 etc"
and the first line of tData keeps being the first line of Dgrid :-((
The syntax isn't correct in this example. It should be:
set the dgText[true] of group "Dgrid" to tData
I just tested to verify that using the correct syntax does work -
and it does :-)
I just tried this syntax but without success!
Here,
-------
set the pFirstLineContainsHeaders of grp "Dgrid" to true
put fld "source" into tData
set the dgText[pFirstLineContainsHeaders] of group "Dgrid" to tData
---- is working
except that I don't get Col 1, Col 2 etc replaced by the first line of
tData
I get the feeling that I am missing somethins else
In your previous post (answer to Jim) you said :
"The most likely cause is that you don't have a column labeled with
"Col 1" or "Col 2" in the first line of the data. Therefore the data
you are setting is not mapping to an existing column in the Data Grid."
Does it mean that the first line of tData should be "Col 1 tab Col 2
etc"
I tried that, and actually, the data grid is filled in but is keeping
the generic names (Col 1, Col 2 etc)
But then what about this phrase in the doc :
"… by passing in true for pFirstLineContainsHeaders. If true then the
data grid will extract the first line of pText and use the values for
the internal key/column names …"
I thought it was meaning that In tData I had to put in the first line,
the names that I would like instead of Col 1, Col 2 etc.
Up to now, I don"t use pFirstLineContainsHeaders ; I set first the
dgData["columns"] and dgData["column labels"].
But always happy to better understand about Data Grid (here about how
this pFirstLineContainsHeaders works; seems I am making a bad
interpretation of the manual.
Thanks Trevor for your always helping advices; I keep appreciating
Data Grid a lot; in a couple of app. I have several ones which are
running very nicely :-))
Best regards from Grenoble
André
