Kde Taskbar

[DarkBlue]

Hello

In linux I use kmail as my email client under KDE,
if a message comes in the Kontact button in the
taskbar changes to blue.
How can I have the same behaviour in a python app ?

I have a python script which runs nicely under linux
now every so often I want to be notified by some event,
in this case that a record has been added to a database
and I want to have the application button in the taskbar
to change color

Thanks for any pointers , I am out of my depth here
