One more question: if the number of columns is greater than 5 you
cant access to the last ones without resizing the window.
Would it be possible to add an horizontal scrollbar if the window's
size is fixed?
From ListMagic docs:
ListMagic allows you to specify a number of columns* or to choose
Auto option.
Why specify a number of columns or choose Auto?
* Nine columns only in this demo stack but as many as you want when
installing the widget.
When choosing Auto option, the widget will fit your data list and
will display as many header tabs as there are items in a data line.
In this case the list will have a horizontal scrollbar because all
columns are shown.
When specifying a number, the widget will display the specified
number of headers disregarding the number of items in a data line.
In this case the list will not have a horizontal scrollbar because
all columns are not shown in order to keep hidden data.
Why would you hide some data?
Having hidden data may appear very useful when processing:
For instance:
A column may display Internet domain names while a hidden column is
storing corresponding urls. Whatever sort can be done, the right data
is always in the right line without needing to build an external
index to get the url.
Actually, the list field itself can contain all needed indexed values
without letting the user seeing or accessing them:
on LMMouseDoubleUp pLineNo
settheitemDelimitertotab
launchurlitem 9 of LMExtractLines(pLineNo)
-- see this function in the syntax section
end LMMouseDoubleUp
In this example, if the number of columns has been set to eight, the
user will not see the url but a double click on the line will open
his browser to the right url because it is item 9 (not displayed) in
the list field and easily retrieved whatever sort can have been made.
See LMMouseDoubleUp message and LMExtractLines function in Syntax
section.
Actually, using hidden data feature depends also on the number of
displayed columns:
Remember that screens are not extendable and only Auto (with no
hidden data) allows a horizontal scroll bar.
Such a choice depends on many things: it is up to you and depends on
your needs.
Hope this clarifies :-)
