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.
