ListView
A ListView control lets you display items and icons in a variety
of arrangements. You can display large or small icons in free-form
lists. You can add columns, pictures, and items to the ListView, and
modify column properties, using PowerScript functions such as
AddColumn, AddLargePicture, SetItem, SetColumn, and so on. For
information about ListView functions, see the section called “Using
ListView controls” in Application Techniques and
the section called “ListView control” in Objects and Controls.
The following illustration from the Code Examples application
shows a ListView control used in a sales order application.
Adding ListView items and
pictures
Adding images to a ListView control is the same as adding images
to a PictureListBox. The ListView control’s Properties view has two
tab pages for adding pictures: Large Picture (default size 32 by 32
pixels) and Small Picture (16 by 16 pixels).
For more information, see Adding images
to a PictureListBox.
