Re: gui Dialog Box

Steffen,
  To force the argument passed
to the program as a character, you must change the first line to:
guiCreate("Property", Name="first",
DialogControl="String", DialogPrompt="first", UseQuotes=T)
  Otherwise, it will look for an
object named whatever you typed in to the dialog box.

Subject	[S] gui Dialog Box

Hey!
 
I created a very simple Dialog Box with the
following code:
 
 
guiCreate("Property", Name="first",
DialogControl="String", DialogPrompt="first")
guiCreate("Property", Name="group1",
 Type="Group", PropertyList = "first")
guiCreate("Property", Name=
"returnvalue", DialogControl = "Invisible", DefaultValue=
"a")
 
test <- function(arg1){
   
   print(arg1)
   invisible()
   
}
 
guiCreate("FunctionInfo",
Name="test", Function="test", PropertyList = "returnvalue,
group1") 
guiDisplayDialog("Function",
Name="test")
 
Unfortunately I get the following error when
entering  a string into the field: 
Problem: Object "text"
not found
 
If I enter a string included in quotation
marks, the error does not occur and the string is passed to the function.
How can I change that behaviour?
 
Thanks a lot
