VisionPro display controls

VisionPro provides four kinds of display controls that you can use to display images and graphics.

Table 1. VisionPro Display Controls

Display Control	Descrption
CogToolDisplay	This is the display control you see in QuickBuild and in the vision tools. You can connect a VisionPro tool to the display control, and extracts the records directly from the tool. It uses a dropdown list to choose the image records to display.
CogRecordsDisplay	This control is similar to the CogToolDisplay control. It lets the user choose an image record from a dropdown list and displays any graphical subrecords of the image. Unlike CogToolDisplay this control does not know anything about VisionPro tools; you must provide the records to be displayed.
CogRecordDisplay	This control displays a single image record and its graphical subrecords. It does not have a dropdown list box, and it does not allow the user to choose an image.
CogDisplay	This is the lowest level display control used as a base by all the other display controls. This control displays a single image and a collection of graphics which must be provided directly to the control.
