I have a data grid "DataGrid" defined with the Inspector. The
columns' headers are aligned to left.
In order to get the columns headers centered I do the following :
------
put the dgProp["columns"] of group "DataGrid" into theColumns
repeat for each line enil in theColumns
set the dgHeaderAlignment[enil] of grp "DataGrid" of this cd to
center
end repeat
-------
Ok, that works well.
I save the stack
If I close the stack and reopen it, the headers are still centered.
But if I quit Rev, when I reopen the stack, the headers are aligned
to left again.
What am I missing?
It's a bug. The Data Grid isn't setting alignment when creating the
headers from scratch.
You can either set the alignment each time your program opens or add
a 1 line fix to the Data Grid behavior script. Instructions follow.
Thanks Trevor for your answer and the precisely explained procedure to
add the line to the _tableCreateHeaders command.
But, when I do so, I get a new issue : after quitting Rev, when I
launch my stack again, the headers of the columns, not only are not
centered anymore but also some of them are even so shifted to the
left, that one can't see the first characters of them; bizarre ;-)
More precisely : could be useful to say that the data grid is on a
substack;
Even without quitting Rev :
- if I close the substack and re-open it the headers keeps centered
- If I close the substack AND its main stack, then, when I re-open
them, I get the headers shifted to the left.
Not a big problem anyway (I can set the alignment each time a card
opens as you suggest); but I am curious about what is happening ;-))
It was the first time I had a look at your scripts in the
revdatagridlibrary; very impressive; "chapeau bas" ;-))
Best regards from Grenoble
