Not implement:

super(Record, self).close()

Due to: [1]

When an application fails and you want to close from the corresponding button occurs:

Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/sugar3/activity/activity.py", line 890, in _keep_failed_dialog_response_cb self.close(skip_save=True) TypeError: close() got an unexpected keyword argument 'skip_save' And the activity is not closed, nor can restart sugar as alert reappears again and again, you need to stop.

This error is caused by the following: When a class B inherits from class A, and in B is overwritten a function of A, A function is no longer running, but instead runs the function of the class B, even when explicitly call function A from B.

Stop using Pixmap instead use Pixbuf:

Replace:

       ctx.rectangle(0, 0, w, h)

       ctx.fill()
