Trevor (and Andre.Bisseret),
Thanks you for the very thoughtful reply(s).
It is heartening to see something defended by its parent. My sincere
apologies for treating your offspring in such a quick and dirty
fashion :-)
I'm sure I will appreciate the richness of this new Run Rev object
in time--see below.
FIrst to satisfy my quick and dirty needs, I find that the following
works well to get data displayed in a data grid field:
on mouseUp
put field "data" into tData --Tab delimited text
--The first line of tData contains the column names
put line 1 of tData into tHeaders
replace tab with cr in tHeaders
set dgProp["Columns"] of group "DataGrid" to tHeaders --Thanks to
Andre for this line.
set the dgText [ true ] of group "DataGrid" to tData
end mouseUp
Your handler above, confirmed by Trevoir, helped me a lot to
understand the possible uses of pFirstLineContainsHeaders.
In order to learn more about data grid, I tried several variations, I
put below in case it could interest someone :
local tData,tHeaders,
-- field "data" = lines of tab delimited text -- a Data Grid
"DataGrid" with 3 columns
------------
-- 1 ) IF THE LINE OF HEADERS IS NOT INCLUDED IN THE DATA (AS I AM
ACCUSTOMED TO)
-- 1.1) WITHOUT USING pFirstLineContainsHeaders; WORKS:
on mouseUp
put "header1" & cr & "header2" & cr & "header3" into tHeaders
set the dgProp["columns"] of grp "DataGrid" to tHeaders
put fld "data" into tData
set the dgText of group "DataGrid" to tData
end mouseUp
-- 1.2) USING pFirstLineContainsHeaders: USELESS BUT WORKS :-)))
on mouseUp
put "header1" & cr & "header2" & cr & "header3" into tHeaders
set the dgProp["columns"] of grp "DataGrid" to tHeaders
put fld "data" into tData
set the dgText[false] of group "DataGrid" to tData
end mouseUp
-- 2) IF, FOR SOME REASON, THE LINE OF HEADERS IS INCLUDED IN THE
DATA (FIRST LINE)
-- 2.1) WITHOUT USING pFirstLineContainsHeaders: WORKS:
on mouseUp
put field "data" into tData
put line 1 of tData into tHeaders
replace tab with cr in tHeaders
set dgProp["Columns"] of group "DataGrid" to tHeaders
delete line 1 of tData
set the dgText of group "DataGrid" to tData
end mouseUp
-- 2.2) USING pFirstLineContainsHeaders: WORKS:
on mouseUp -- the handler from Jim
put field "data" into tData
put line 1 of tData into tHeaders
replace tab with cr in tHeaders
set dgProp["Columns"] of group "DataGrid" to tHeaders --Thanks to
Andre for this line.
set the dgText [ true ] of group "DataGrid" to tData
end mouseUp
-------------------------------------------------
-- indeed, in all these handlers, it's possible to directly set the
dgText of grp "datagrid" to fld "data" (but less fast, I guess,
specially if it contains a lot of lines)
--------------------------------------------------
AS FOR THE SYNTAX OF pFirstLineContainsHeaders
OK: set the dgText[true]
nevertheless:
put true into pFirstLineContainsHeaders
set the dgText[pFirstLineContainsHeaders] of grp "datagrid" to true
works as well, but useless, OK :-)
set the pFirstLineContainsHeaders of grp "datagrid" to true does not
work as that is creating a custom prop; OK :-))
I am a bit slow-witted but I am beginning to understand quite what
this pFirstLineContainsHeaders can do ;-o)))))
Thanks to both of you,
André
