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 online Help.
The following illustration from the Code Examples application shows a ListView control used in a sales order application.
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”.
Select the ListView control to display its properties in the Properties view and then select the Items tab.
Enter the name of the ListView item and the picture index you want to associate with it. This picture index corresponds to the images you select on the Large Picture, Small Picture, and State property pages.
On the Items tab page, you can work with rows in this way:
