List Image Column (PRIM_LIST.Image)
Column displaying an image
Ancestors - List Column (PRIM_LIST.Column) Object (PRIM_OBJT)
Prim_List.Image is a column in a List used to display images. Each column type has a corresponding CurrentItem class that provides access to the individual entries in the column accessible via the CurrentItem property. The image for each item can be modified independently using the current item for the column in the same way that other visual LANSA lists allow the current item for the list to be used. An image column is created whenever an Image control is dropped on the list. If a Blob field is dropped on the list, the Source property will be set to the field and it will be used as a column in the underlying working list. If the field value at run time contains a valid image file, the image will be shown. This is a simple and convenient shortcut that simplifies the processing of text and image data when being read from a database.
This example shows a 4 column list, each using a repository field as the source. The image column has a source of a Blob field EMPTHM. This is rendered as an image at runtime.
