"ask list" [SCd] version ? in [LCd] ??

[mcelvain]

In SuperCard, the "Ask List" XCMD (?) was helpful: is there a LiveCode version, or does one just keep using a crafted palette for the job of calling a selectable list during a handler, which returns with the value(s) of hilited button(s) ?

†his is it's SuperCard dictionary citation:

ask list textList [prompt prompt] [with button1 [or button2]][using stylesList] [hilitedLines numberList] [at loc] [return {text|lines}]
ask list myList prompt "Please choose an item:" return lines
ask list (cd fld 4) prompt "Please choose an item:" with "Cancel" or "Select" using "selContig,selFilled" hilitedLines "1,2" at 500,500 return text

Sorry, this one's a roll-your-own. That said, so many of us have made list picker dialogs I'm sure there's an example floating around that's sharable.

Anyone have one already generalized for our SuperCard friend?

Don’t have a generalisable one but have done such things using a datagrid - I guess a list field or polygrid would also do nicely.

I’m not sure I’ve ever seen an OS interface element that does this (other than pop up menus etc, which already exist in LC).

@mcelvain: you don’t mean pop up/dropdown menus or something similar do you?

A simple list field would do, with Cancel and Select buttons, in a modal dialog.

The more I think about it, it's self-contained enough that it might make an excellent exercise for the reader.

Macelvain, take a look at the modal command, the dialogData property, and the properties associated with list fields. Let us know where anything you encounter isn't clear and we can provide guidance.

Will do, Richard; and thank-you.

Stam, what I'm looking to build is not a menu button, but a simple list dialog.

I'll have a look at Modal Command, DialogData property; further looking at List Field properties.
