Maplets[Elements][Item] - specify an item in a box element

Calling Sequence





equation(s) of the form value=string; specify options for the Item element



The Item element specifies an item in a ComboBox, DropDownBox, or ListBox element.


The Item element features can be modified by using options.  To simplify specifying options in the Maplets package, certain options and contents can be set without using an equation. The following table lists elements, symbols, and types (in the left column) and the corresponding option or content (in the right column) to which inputs of this type are, by default, assigned.

Elements, Symbols, or Types

Assumed Option or Content



string or symbol

value option




An Item element cannot contain other elements.


An Item element can be contained in a ComboBox DropDownBox, or ListBox element.


The following table describes the control and use of the Item element options.


An x in the I column indicates that the option can be initialized, that is, specified in the calling sequence (element definition).


An x in the R column indicates that the option is required in the calling sequence.


An x in the G column indicates that the option can be read, that is, retrieved by using the Get tool.


An x in the S column indicates that the option can be written, that is, set by using the SetOption element or the Set tool.






















The opts argument can contain one or more of the following equations that set Maplet application options.




value = string or symbol


A string that is an entry in a combo, list, or drop-down box.


A Maplet application that prompts the user for a favorite color:


maplet:=MapletPick your favorite color: ,ComboBox'CoB1'Itemred,Itemgreen,Itemblue,Itemnone of the above,ButtonOK,Shutdown'CoB1',ButtonCancel,Shutdown:


This can be done more easily by using a list in a ComboBox.

maplet:=MapletPick your favorite color: ,ComboBox'CoB1'red,green,blue,ButtonOK,Shutdown'CoB1',ButtonCancel,Shutdown:
