Filter Col Selection Properties: Limit selection

Robbb

Hi everybody,

since JMP 15 (or 14?) there is this wonderful Filter Col Selection. I am trying to use it for my own GUI in a JSL script.

colList = Filter Col Selector( Width( 256 ), N Lines( 20 ), Max Selected( 1 ) )

Somehow Max Selected (1) does not work, even though I see it in the property list, when calling show properties(colList).

It works when replacing Filter Col Selector by a Col List Box, but then I loose the nice filter function.

What am I doing wrong? How to limit the number of selected elements of a Filter Col Selector?

Hi,

Here is a possible solution to your problem: the Set Max Selected needs to be applied to the colList variable separately:

Names Default to Here (1);

dt = Current Data Table ();

nw = New Window("TEXT",colList = Filter Col Selector( dt, Width( 256 ), N Lines( 20 )));

colList << Set Max Selected (2);

Hi Rob,
It might be obvious but based on the JMP help section, the command Filter Col Selector does not appear to have an option for specifying Maximum selected items.
Best,

Hi Thierry,

It seems to me it does have this possibility:

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
New Window( "Filter Col Selector Example",
	fontobj = lb = Filter Col Selector( width( 250 ) )
);
Show Properties(fontobj)

The long output lists

Set Max Selected
Get Max Selected

as well as

Set N Lines
Get N Lines

as available Functions.

N Lines works, Max Selected does not for some reason.

@Thierry_S provided you a perfect solution.

Just a simple syntax addendum: any property that seems to be added once created typically can be added as , <<property.

So this works as well.

Names Default to Here (1);

dt = Current Data Table ();

nw = New Window("TEXT",colList = Filter Col Selector( dt, Width( 256 ), N Lines( 20 ), << Set Max Selected (2)));

Yes, that kind of works. Thanks.

However, the behavior with Set Max Selected (1) of a Filter Col Selector is different than with a Col List Box. I can still select multiple entries by holding down shift and up or down. Is it a bug? Set Max Selected (2) works like expected i.e. it is not possible to select more than 2, even with the keyboard.

@gzmorgan0 Thanks, I learned something. Just out of curiosity: How and why is the Max Selected Property different here from Width or N Lines for example?
