Hello,

I am writing a simple program to display my study notes every few minutes. I would like to use KNotify (like this) instead of the QSystemTrayIcon balloon. How can I call KNotify instead of the balloon?

Code: Select all

from PyQt4.Qt import QApplication, QSystemTrayIcon

app = QApplication([])
tray = QSystemTrayIcon(ic)
tray.setVisible(True)

mynote = """Economics is the social science that analyzes the production, distribution, and consumption of goods and services."""

tray.showMessage("Memorize!", mynote, tray.Critical, 20000)

Thanks,

Eduardo

Thanks for your time, bcooksley.

I updated kdelibs with «sudo apt-get install kdelibs» and tried:

Code: Select all

from PyQt4.Qt import QApplication, QSystemTrayIcon, QIcon
>>> import dbus
>>> notify = dbus.Interface(dbus.SessionBus().get_object('org.kde.VisualNotifications', '/VisualNotifications'), 'org.kde.VisualNotifications')

But got the following error message:

Code: Select all

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    notify = dbus.Interface(dbus.SessionBus().get_object('org.kde.VisualNotifications', '/VisualNotifications'), 'org.kde.VisualNotifications')

DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.kde.VisualNotifications was not provided by any .service files

What am I doing wrong?

"knotify4" is likely not running, although if you are in a KDE session, it should be.

Thank you again, bcooksley. I understand the problem now! It happens that I found the notifier so pretty, I thought it couldn't be Gnome, it had to be KDE...! Ubuntu uses NotifyOSD.

Both GNOME and KDE implement a XDG Notifications specification, I suggest implementing that. Look at org.freedesktop.Notifications on D-Bus.
