Calling Sequence

GetInput(msg, opts)




string or symbol



equation(s) of the form option=value where option is one of title, type, or value; specify options for the Maplet application



The GetInput(msg) calling sequence displays a Maplet application that prompts the user for input. The user can enter text in the input field and click OK, which returns the text, or the user can select Cancel, which raises an exception.


The GetInput sample Maplet worksheet describes how to write a Maplet application that behaves similarly to this routine by using the Maplets[Elements] package.


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




title = string or symbol


Specifies the Maplet application title.  By default, the title is Requesting Input.




type = `error`, information, plain, or warning


The input request type.  By default, the type is plain. This option determines the icon that is located left of the text.




value = string or anything


The text that initially appears in the input field.  If this option is not of type string, it is converted to one by using sprintf"%a",....  The default value is .



GetInputThis expression does not parse, please correct:,'value'=2 x + 3,'type'=`error`
