The docs (http://www.fxruby.org/doc/api/classes/Fox/
FXInputDialog.html) are very clear, IMHO

Need more details or a code sample?

Cheers

Hi Chris,

Here is the script:

require ‘fox16’
include Fox

result = FXInputDialog.getString(“Enter some text…”,self,“New
InputDialog”,“Please type some text:”)
if result
print "User entered: " + result
end

Here is the result of running the script:

C:\ruby\self\fox>fox1.rb
C:/ruby/self/fox/fox1.rb:4:in `getString’: No matching function for
overloaded ‘FXInputDialog_getString’ (ArgumentError)
from C:/ruby/self/fox/fox1.rb:4

I am sure what is wrong?

I was hopping you’d provide a sample of code showing what you are
trying to do :wink:

a very simple example:

result = FXInputDialog.getString(“Enter some text…”,self,“New
InputDialog”,“Please type some text:”)
if result
print "User entered: " + result

cheers

Sorry about that, I was on a computer without Ruby so it only worked
in Theory :wink:

Here is a full working example:
require ‘rubygems’
require ‘fox16’
include Fox

if FILE == $0
FXApp.new do |app|
app.create
result = FXInputDialog.getString(“Enter some text…”,app,“New
InputDialog”,“Please type some text:”)
if result
puts "User entered: " + result
else
puts “User cancled!”
end
end
end

The dialog requires an app (or a parent window), my initial example
didn’t account for that

Any clearer?

require ‘rubygems’
require ‘fox16’
include Fox

if FILE == $0
FXApp.new do |app|
app.create
result = FXInputDialog.getString(“Enter some text…”,app,“New
InputDialog”,“Please type some text:”)
if result
puts "User entered: " + result
else
puts “User cancled!”
end
end
end

Now the code is working. I have one more question. I copy one method
from FxRuby’s rdoc as follows:

getString(initial, app, caption, label, ic=nil)
Prompt for a string, in a free-floating window…

What does ic=nil mean?

Thanks,

Li

Sorry there is a typo in my earlier post: I am NOT sure what is wrong
about the results when I followed Chris’s code sample.

Thanks,

Hi Chris,

Thank you very much. Now I think it is a little bit easier for me to
read the FxRuby API document.

Don’t see anything in the FXRuby docs, but according to the Fox docs
for FXInputDialog that parameter is an FXIcon. So I guess you can
pass a reference to an Icon to be displayed in the dialog
