On Screen Keyboard

I was wondering if there was any examples of how to implement an "on-screen keyboard". The experiment deals with a subject trying to unscramble words. The idea is to put a keyboard on the screen and have them click the letters in order to spell out the word. I was thinking of implementing 26 buttons, individually, but I wasn't sure if that was the best way to go about making this keyboard. Any other methods?

Thanks

There aren't any examples, but it shouldn't be too difficult. I would use button labels to create the keyboard.
Code:
A = viz.add(viz.BUTTON_LABEL,'A')
.
.
Z = viz.add(viz.BUTTON_LABEL,'Z')

How about allowing the user to re-arrange the letters with drag and drop?

That would also be very useful. Is there a function that would allow me to do this? Any prior example or helpful hints?

Thanks for the great idea!

An easy way to do this:

Click on letters with the mouse to select them.
Click arrow buttions to move them forward or back within the word

Sounds good to me. Is there anyway to "update" the letter label each time an "enter button" is clicked. Preferably I would like to perform a refresh where the buttons would go back to the original positions and be labeled with new letters.

I just implemented some buttons using the following code. I'm planning on the user to be able to click on a button and that letter should come out as text on the screen. I have done this previously with the keyboard using:
Code:
def mykeyboard(key):
 global SendText, infoindex, quad
 #the input is a normal character
 if len(key) == 1:
  SendText += key
 elif key == viz.KEY_BACKSPACE:
  #If the key is the backspace key then remove the last character
  SendText = SendText[:len(SendText)-1]
 #Update the input text
 text.message(SendText)
Is there a way to do something like the following for any letter that is clicked. I was thinking of doing an if statement for each letter that will appear:
Code:
 if viz.add(viz.BUTTON_LABEL,'a') and state == viz.DOWN:
  SendText += 'a'
Code:
if infoindex == 0:
 one = viz.add(viz.BUTTON_LABEL, 's')
 two = viz.add(viz.BUTTON_LABEL, 'h')
 three = viz.add(viz.BUTTON_LABEL, 'a')
 four = viz.add(viz.BUTTON_LABEL, 'o')
 five = viz.add(viz.BUTTON_LABEL, 'n')
 six = viz.add(viz.BUTTON_LABEL, 'c')
 seven = viz.add(viz.BUTTON_LABEL, ' ')
 eight = viz.add(viz.BUTTON_LABEL, ' ')
 nine = viz.add(viz.BUTTON_LABEL, ' ')
 ten = viz.add(viz.BUTTON_LABEL, ' ')
 eleven = viz.add(viz.BUTTON_LABEL, ' ')
 twelve = viz.add(viz.BUTTON_LABEL, ' ')
 if infoindex == 1:
  one = viz.add(viz.BUTTON_LABEL, 'z')
  two = viz.add(viz.BUTTON_LABEL, 'a')

I have 14 words that need to be unscrambled. What I have set up so far is 12 buttons on the screen (the longest word that needs to be unscrambled is 12 letters long) and a button that will be used as an enter key. What I had planned to do is have the letters for the current word on each button and have the remaining letters (if the word < 12 letters long) blank. the user will then have to click the letter they believe comes next in the correct order. Each time a letter is clicked, it will be displayed on a text object. Using the keyboard, I just used the my keyboard code that I have previously posted. Unfortunately it's too difficult for someone that is wearing an HMD to type words so I was trying to implement an "onscreen keyboard" with these buttons. Eventually, i will add a "backspace" button in case a user makes a mistake, but that will come later. Right now, I would just like for the user to be able to click the letter and have it appear on the screen in the same manner as if the user were typing it. The keyboard example was taken from the IM tutorial.

You can check if a button is "down" with myButton.get()

Ok, that worked, now the next step is for the program to recognize which button is pushed. Here is the code I have so far:
Code:
def mybutton(button,state):
 global SendText, infoindex, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve
 letter = ''
 if button == send and button.get() == viz.DOWN:
  #Send the current text to the mailbox
  #Reset the text to nothing
  SendText = ''
  text.message(SendText)
  if infoindex <= 15:
   info.visible(1)
   infoindex = infoindex + 1
   one.remove(viz.BUTTON_LABEL)
   two.remove(viz.BUTTON_LABEL)
   three.remove(viz.BUTTON_LABEL)
   four.remove(viz.BUTTON_LABEL)
   five.remove(viz.BUTTON_LABEL)
   six.remove(viz.BUTTON_LABEL)
   seven.remove(viz.BUTTON_LABEL)
   eight.remove(viz.BUTTON_LABEL)
   nine.remove(viz.BUTTON_LABEL)
   ten.remove(viz.BUTTON_LABEL)
   eleven.remove(viz.BUTTON_LABEL)
   twelve.remove(viz.BUTTON_LABEL)
  elif infoindex > 15:
   text.visible(0)
   button.visible(0)
   HEAD_DEPTH = -12.5
   viz.translate(viz.HEAD_POS,0,0,HEAD_DEPTH )
   instructor1 = viz.add('male.cfg')
   instructor1.face('biohead_talk.vzf')
   instructor1.threatening = INSTRUCTOR
   instructor1.tag = 0
   instructor1.appearance = 0
   instructor1.facepic = 0 
   Instructions(instructor1)
   info.visible(0)
   #bulletinfo.visible(1)
 if viz.add(viz.BUTTON_LABEL,'a') and state == viz.DOWN:
  letter = 'a'
 elif viz.add(viz.BUTTON_LABEL,'b') and state == viz.DOWN:
  letter = 'b'
 elif viz.add(viz.BUTTON_LABEL,'c') and state == viz.DOWN:
  letter = 'c'
 elif viz.add(viz.BUTTON_LABEL,'d') and state == viz.DOWN:
  letter = 'd'
 elif viz.add(viz.BUTTON_LABEL,'e') and state == viz.DOWN:
  letter = 'e'
 elif viz.add(viz.BUTTON_LABEL,'f') and state == viz.DOWN:
  letter = 'f'
 elif viz.add(viz.BUTTON_LABEL,'g') and state == viz.DOWN:
  letter = 'g'
 elif viz.add(viz.BUTTON_LABEL,'h') and state == viz.DOWN:
  letter = 'h'
 elif viz.add(viz.BUTTON_LABEL,'i') and state == viz.DOWN:
  letter = 'i'
 elif viz.add(viz.BUTTON_LABEL,'l') and state == viz.DOWN:
  letter = 'l'
 elif viz.add(viz.BUTTON_LABEL,'m') and state == viz.DOWN:
  letter = 'm'
 elif viz.add(viz.BUTTON_LABEL,'n') and state == viz.DOWN:
  letter = 'n'
 elif viz.add(viz.BUTTON_LABEL,'o') and state == viz.DOWN:
  letter = 'o'
 elif viz.add(viz.BUTTON_LABEL,'p') and state == viz.DOWN:
  letter = 'p'
 elif viz.add(viz.BUTTON_LABEL,'r') and state == viz.DOWN:
  letter = 'r'
 elif viz.add(viz.BUTTON_LABEL,'s') and state == viz.DOWN:
  letter = 's'
 elif viz.add(viz.BUTTON_LABEL,'t') and state == viz.DOWN:
  letter = 't'
 elif viz.add(viz.BUTTON_LABEL,'u') and state == viz.DOWN:
  letter = 'u'
 elif viz.add(viz.BUTTON_LABEL,'v') and state == viz.DOWN:
  letter = 'v'
 elif viz.add(viz.BUTTON_LABEL,'x') and state == viz.DOWN:
  letter = 'x'
 elif viz.add(viz.BUTTON_LABEL,'y') and state == viz.DOWN:
  letter = 'y'
 elif viz.add(viz.BUTTON_LABEL,'z') and state == viz.DOWN:
  letter = 'z'
 SendText += letter
 text.message(SendText)
The problem I'm having is that no matter what button I push, an "a" is printed in text. Am I doing something wrong? Is it ok to use the if viz.add() to implement this? The way I see this code is that whatever button (letter) I press, that letter should be the next one to pop up. In other words, how can I access the BUTTON_LABEL attribute to use it in my if logic.

You can save the label somewhere when you assgin it.
Code:
buttonLabel = 'mylabel'
button = viz.add( viz.BUTTON, buttonLabel   )
button.label = buttonLabel

...

print button.label
I suggested something similar when you are attaching weapons to avatars.

I tried this but it gave me an error:
Code:

The code should be:
Code:
button = viz.add(viz.BUTTON_LABEL,buttonLabel)
