Displays information on the controls on the screen, or prints the same information using your print function, which you specified through the It_SetDumpHook function.

The information provided for printing includes:

• The id of the screen (the iModal member of the IT_SCREEN structure)
• The name, value, left, and top members of the IT_CTRL structure

You use It_ListCOntrols in conjunction with It_SetDumpHook. For more information, see Listing Screen and Control Information.

The ItEv_DumpEvent function displays a larger set of information: it lists all of the items on the screen associated with the current event, not only controls, as It_ListControls does. However, It_ListControls gives you the flexibility of defining print format and target device when you use it with It_SetDumpHook.
