Chapter 6: Using Lists and Tree Views in a Window

Using report view

ListView report view requires more information than the large icon, small icon, and list view. To enable report view in a ListView control, you must write a script that establishes columns with the AddColumn and SetColumn functions, and then populate the columns using the SetItem function.

Populating columns

Use AddColumn to create columns in a ListView. When you use the AddColumn function, you specify the:

Column label The name that will display in the column header
Column alignment Whether the text will be left-aligned, right-aligned, or centered
Column size The width of the column in PowerBuilder units

This example creates three columns in a ListView:

This.AddColumn("Name", Left!, 1000)

This.AddColumn("Size", Left!, 400)

This.AddColumn("Date", Left!, 300)

Setting columns

Use SetColumn to set the column number, name, alignment, and size:

This.SetColumn (1, "Composition", Left!, 860)

This.SetColumn (2, "Album", Left!, 610)

This.SetColumn (3, "Artist", Left!, 710")

Setting column items

Use SetItem to populate the columns of a ListView:

This.SetItem (1, 1, "St.Thomas")

This.SetItem (1, 2, "Saxophone Colossus")

This.SetItem (1, 3, "Sonny Rollins")

This.SetItem (2, 1, "So What")

This.SetItem (2, 2, "Kind of Blue")

This.SetItem (2, 3, "Miles Davis")

This.SetItem (3, 1, "Good-bye, Porkpie Hat")

This.SetItem (3, 2, "Mingus-ah-um")

This.SetItem (3, 3, "Charles Mingus")
