• listpick ?options? list
Display a dialog with the list displayed in a table view. If the user presses the Cancel button, an error is returned. If the user selects the OK button, or double clicks an item in the list, that item will be returned. Valid options are:

-attributes num	attributes of the list view
-cancel str	text of the Cancel button
-header list	headers at the top of the list view columns
-height num	height of the dialog
-indices	use indices rather than names
-l	synonym of -multi (deprecated)
-L list	a list of default item(s) to be initially selected
-multi	allow multiple items to be selected, return a list
-num num	number of columns in the list view (default is 1)
-ok str	text of the OK button
-prompt str	prompt text at the top of the dialog
-truncate str	set the truncation mode
-width num	width of the dialog
--	end of options

The -attributes option takes the same values as the -attr option of the Table View view (see the table of possible values). If the -attributes option is not specified, the command sets the following flags by default: AllowsTypeSelect, UsesAlternatingRowBackgroundColors, AllowsColumnResizing, AllowsEmptySelection. If there is only one column, the NoHeader attribute is also set by default.
If the -num option is specified with value n, the list of items is a list of n-element sublists: each sublist corresponds to the n elements displayed in a row.
If accompanied by -multi, all items in the -L list will be selected, otherwise only the first item is selected.
If the -indices option is specified, the command returns a list of the indices of the selected items and, in that case, the -L option expects a list of the indices of the default item(s) to be initially selected.
The -truncate option sets the truncation mode used to display items that are too long to fit in the width of the table. It takes the same values as the -truncate option of the Table View view (see the possible values here).
