A Combo Box object presents a drop-down menu of options from which the user may select one. A Combo Box tool can be used in many of the same situations where a Radio Button would be used. The advantage of the Combo Box is that it takes up less space on TheView.
The list of items in the drop-down is defined using the object’s ListItems property. Each item has a Name and Value, either of which can be called in script. The Value must be a positive integer.
The Combo Box can be one of two types: Drop-down or Droplist. The default type is Droplist, which is a static list of items. The Drop-down type allows you to type in the selection field, thereby entering a new item.
When this occurs, the Name of the item is the user-entered text. The Value of the item is set to -1 (not found).
The number of items displayed in the drop-down is specified by the NumDropped property. The default is 2. Be sure to set this to a higher number if you have more items in the list. The recommended type is Droplist.
Custom colors can be applied to the object. To use custom colors, set the UseColors property to 1 - Yes and then specify the colors using the BackColor and ForeColor properties.
Script is required for an action to occur when using a Combo Box object. See Scripting Examples.
