A tooltip can be associated with a picture, which is a tiny box that is displayed next to the picture and identifies it in the Results and Table section. For Dynamic pictures, the tooltip field accepts a column name which represents a non-BLOB column item on the request line used to describe the picture. If no tooltip is selected for a BLOB image, the picture column text shows <<Picture: unique id>>. In this case, the unique id is the tooltip text. Otherwise, the corresponding primary key value is shown. For static images, the tooltip is text that you specify on the properties dialog of a picture.
To associate a tooltip with a BLOB image:
Right-click and select Properties.
The Items Properties dialog box is displayed.
The Datatype drop-down and Tooltip drop-down are displayed. The Tooltip drop-down contains a list of all non-blob items on request line, and a “None” (default) option.
From the Tooltip drop-down, select the non-BLOB image to use as the tool tip.
