Re: [Pythoncard-users] audio recording Interface ?

[Alec B. <wry...@gm...>]

There's nothing Pythoncard-specific about the audio recording task, you
simply need a GUI with a record button if I understand correctly? And
probably a countdown to let them know how much time they have left unless
they press the stop button? In the Pythoncard Resource Editor you'll simply
be placing a bitmap button on a frame. If you want that record button to
turn into a stop button while they're recording, you'll use SetBitmapLabel
if I remember correctly, to change the graphic of the button. And in the
Resource Editor, you'll add a command that is triggered when that button is
pressed. For example the command might be called RecordButton, and in your
file you'll put this line:

on_RecordButton_command(self, event):
 ...print "record was pressed"
....#(do something here)

As far as the countdown, you can either put it in the statusbar (look around
for some examples, there are lots) or I believe you could update the text on
a statictext widget.

To check the time remaining and update the countdown, you'll use a timer.
Timers are quirky and are applied to a specific widget, look for samples.

For the audio recording, I did something very similar to what you're
describing (a "confessional" at Burning Man) using this code as a starting
point:
