A non modal popup that notifies the user that a background task has
been completed. This class guarantees that only a single popup is
visible at any one time. Other requests are queued and displayed after
the user dismisses the current popup.
:param callback: A callable that is called with payload if the user
asks to proceed. Note that this is always called in the GUI thread.
:param cancel_callback: A callable that is called with the payload if
the users asks not to proceed.
:param payload: Arbitrary object, passed to callback
:param html_log: An HTML or plain text log
:param log_viewer_title: The title for the log viewer window
:param title: The title for this popup
:param msg: The msg to display
:param det_msg: Detailed message
:param log_is_file: If True the html_log parameter is interpreted as
the path to a file on disk containing the log
encoded with utf-8
:param checkbox_msg: If not None, a checkbox is displayed in the
dialog, showing this message. The callback is
called with both the payload and the state of the
checkbox as arguments.
:param checkbox_checked: If True the checkbox is checked by default.
:param action_callback: If not None, an extra button is added, which
when clicked will cause action_callback to be called
instead of callback. action_callback is called in
exactly the same way as callback.
:param action_label: The text on the action button
:param action_icon: The icon for the action button, must be a QIcon object or None
:param focus_action: If True, the action button will be focused instead of the Yes button
:param show_det: If True, the Detailed message will be shown initially
:param show_ok: If True, OK will be shown instead of YES/NO
:param icon: The icon to be used for this popop (defaults to question mark). Can be either a QIcon or a string to be used with I()

:param callback: A callable that is called with payload if the user
asks to proceed. Note that this is always called in the GUI thread.
:param cancel_callback: A callable that is called with the payload if
the users asks not to proceed.
:param payload: Arbitrary object, passed to callback
:param html_log: An HTML or plain text log
:param log_viewer_title: The title for the log viewer window
:param title: The title for this popup

:param det_msg: Detailed message
:param log_is_file: If True the html_log parameter is interpreted as
the path to a file on disk containing the log
encoded with utf-8
:param checkbox_msg: If not None, a checkbox is displayed in the
dialog, showing this message. The callback is
called with both the payload and the state of the
checkbox as arguments.
:param checkbox_checked: If True the checkbox is checked by default.
:param action_callback: If not None, an extra button is added, which
when clicked will cause action_callback to be called
instead of callback. action_callback is called in
exactly the same way as callback.
:param action_label: The text on the action button
