Image items define areas where a picture file can be displayed.

Usage
A
Static Image displays an image
that has its source file defined by the
image property.
This type of image item must be used to display text that does not
change often, such as background pictures or logos. The item is not
a formField. The image file can be changed from the BDL program by
using the API provided to manipulate the user interface (see the
Genero
Business Development Language User Guide topic
Dynamic User
Interface for more details). It is not possible to change the
image with a DISPLAY TO instruction.
A
formField Image is a widget that gets the image
file based on the underlying
formField.
The value of the formField is the image file specified with a URL.
The formField can be associated with a database column by changing
the
fieldType property
to TABLE_COLUMN, and specifying the sqltabName and colName properties.
This type of image item must be used to display values that
change often during program execution, like database information.
The picture can be changed from the BDL program by using the
DISPLAY TO instruction to set the value of the field.
