Graphical Panel Controls: Drop Down List

A Drop Down List control allows input from a list of items. The elements of the list can be either manually entered within the control or taken from the list of name/value pairs in a state-encoded signal.

Figure 1: A Drop Down List control with four options, the third of which is currently selected.

In addition to the Common Control Properties that apply to all controls, the Drop Down List control has an additional property described in Table 1.

Double-click this entry to bring up a dialog box where you can enter the items for the list and the values they represent (Figure 2). Simply type a name in the List Item box and a matching value in the Value box, then click the Add button or press Enter. Vehicle Spy will add the item to the list in the bottom of the dialog, and automatically increment the Value counter for the next item as a convenience. You can also click Load From Signal to import name/value pairs from a state-encoded signal.
