Showing a default value in 'Inputs'

[+Delta68]

Is it possible to re-display a previously entered value as the default value if an input is called a second time?

 

eg like the java script:

 

strTxt = prompt("Message", strTxt);

 

or the Visual Basic:

 

strTxt = InputBox("Message", , strTxt)

 

 

thanks

I don't know how to do that using the visual interface of the Groundspeak builder, because that prompts you for a constant string text when you build a Message element.

 

It's perfectly possible in Lua, because a Message is simply

Wherigo.MessageBox{Text=sometext [, Media=someobject]}

 

So you can say

mytext = "Old value=" .. value
Wherigo.MessageBox{Text=mytext}

 

That will either require editing the Lua file (disadvantage: you can't read it back in; if you do, the builder will crash at worst, drop your code at best), or an upgrade to Earwigo, where you can mix arbitrary Lua statements with visually-generated code, anywhere you like.

Thanks for the reply that's not quite what I wanted.

 

What I wanted was the input textbox on an 'Input' to be pre-populated.

 

I think what I might do is set display text dynamically showing the current value and then only update the variable if something is actually entered

 

 

 

Thanks

Ah. I suspect that I "knew" that wasn't possible, and fast-forwarded to the workaround using the prompt.
