Beginner question

Hi everybody,

I just started working with FXRuby and I maybe somebody can help me with a problem.

Just for fun, I wrote a quiz game in Ruby, but up to now it is only running in a DOS window.

To get it a little bit more attractive, I wanted FXRuby to present the questions in a window
and open a field for the user to type in the answer. The answer should then be sent to the main program
as a string variable "response".

I've tried it like this, following the "hello"-example that comes with FX Ruby...

application = FXApp.new("Hello", "FoxTest")
main = FXMainWindow.new(application, "Hello", nil, nil, DECOR_ALL)
FXButton.new(main, frage, nil, application, FXApp::ID_QUIT)
FXButton.new(main, p1, nil, application, FXApp::ID_QUIT)
FXButton.new(main, p2, nil, application, FXApp::ID_QUIT)
FXButton.new(main, p3, nil, application, FXApp::ID_QUIT)
FXButton.new(main, p4, nil, application, FXApp::ID_QUIT)
application.create()
main.show(PLACEMENT_SCREEN)
application.run()


# p1,p2,p3 and p4 are the variables that contain the answer possibilties
# frage is the question


Now, everything is displayed but I don't know how to give the user the chance to type the answer into a text field
and then this should be sent to the main program... any idea?

Ah, and the program works with a while-loop and after the first run I get an error:
"attempted to create more than one FXApp instance (RunTimeError)"
Does anyone know what s the problem here?

Thank you for all answers!

from here on FXApp takes over program control. you need to call your code via event handlers. Check out the connect function. 

# p1,p2,p3 and p4 are the variables that contain the answer possibilties
# frage is the question

Add a FXTextField for entering the answer. Then bind your code that evaluates the answer to a button event handler like this:

button.connect(SEL_COMMAND) { 
// do something here

}

Ah, and the program works with a while-loop and after the first run I get an error:
"attempted to create more than one FXApp instance (RunTimeError)"

You can only have one FXApp instance. When you start FXApp it starts the "GUI-Thread" or others might call it the message loop and calls your code from there. So if you want to have something executed in a FXRuby application you either register event handlers to your buttons and textfield events or start a separate thread for non GUI related things.

you don't need the while loop, the FXApp has its own main loop.

Thank you for your response!

Do you know if there is any FXRuby turorial which starts at the beginning and explains the commands with details?
I bought the book "FX Ruby: Create Lean and Mean GUIs with Ruby", but its quite difficult for me to follow the commands.
I would need a tutorial that explains step by step the command with examples... is there any?

Thanks for your answers...

ps: if somebody would like to talk from time to time about ruby questions or about FXRuby codes/problems, feel free to add me to the
MSN messenger.

you might want to play around with FoxGUIb which will help you understand how to build fxruby GUIs. there is also an accompanying users guide that is targeted on beginners

Meinrad,

I for one would like more tutorials on using fxGUIb.

and how to use some of the other controls like matrix (presume it's a table type widgit and with little help info within each popup ? button within event manager doesn't help me much either - or is fxRI the one i need??).


I must admit i am not the brightest programmer and what might seem self explaitory to some is likely to be hard for me to interpret.

I learn best by doing but as of late haven't had an itch to scratch so to speak.

but have wanted to dabble with fxGUIb lately but - lacking good help/pointers and what i'm after is _very_ basic things like capturing the enter keypress. To get a response into a label (but later have it call a sqlite3 Select function) and have data servered up.

think there is a data awear widget but being very much a novice I've not looked round much.
 
any pointers to better or more fleshed out tutorials?

rdgs,

Dave.

Sorry there are no other tuts that I know of about foxGUIb. I like hacking code and don't like writing tutorials ;) .... I suggest you read the FXRuby guide and/or Lyles book.
FoxGUIb is a tool I wrote to help me and my co-workers with GUI creation. I made it open source since I felt others will find it useful AS IT IS with all its limitations and problems but I have other goals now and would like to move on.

If you have any questions about fxruby or guib, you are welcome to ask here on the list.
