[1/4] from: gaofeng860918:gma:il at: 1-May-2006 9:45
the first one is how to set the button position?please give me a example!
(maybe i want it be located in the center of the window )
the second is how to play a mp3 in the program ??
i want my program has a backgroud audio!
the third one is not on vid ,it is about "request"
this function has a refinement called type ,we can see it by using "help
request"
help request
request argument /type icon
icon--can be info ,help (default),alert
but why the code can not work:
request/type "your age?" info
the rebol told me that type need a "word!" argument !

This one can sometimes get a little confusing, so I'm sure someone else can
give a better explanation than me ^.-

Rebol (as far as I know) only supports certain types of WAV files right now

request/type "You age?" 'info
The single apostrohpe ' in front of the info designates it as a word.

Hi Gao,
Try this:
view layout [ size 200x200 at 50x50 button "Request" [ request/type "Your
info?" 'info ]]
MP3s are not supported currently natively in Rebol.

Take a look at Nick Antonaccio's tutorial, it may help:

Rebol does not have a built-in MP3 player. You could try to use the
call function to start an external MP3 player see
http://www.rebol.com/docs/shell.html (call is now available in
REBOL/View).

The argument for the /type refinement must be a REBOL word! datatype:
request/type "your age?" 'info
or request/type "your age?" to-word "info"
When you {enter request/type "your age" info} REBOL evaluates the word
info - it is not set, hence the error. It may seem strange but if you
first set info to the "lit-word" 'info your original statement would
work:
info: 'info
request/type "your age?" info
Victor Pavlu's tutorial has a good explanation of word, get-words,
set-words and lit-words at http://www.rebol.net/article/0201.html
