Currently I'm developing KDE Plasma/Wallpaper plugin with D-Bus interface(small learning project). I have multi-monitor setup and would like to be able to address each D-Bus Plasma/Wallpaper instance independently(running on different monitors or even on separate KDE Activities) and my initial idea was simple: register separate D-Bus services with unique name(i.e. "com.example.prettydesktop.wlp-"+unique_screen_id) for each instance of plugin. However I couldn't find any way to get screen id from PyKDE Wallpaper because it's not QWidget subclass and thus I can't use QDesktopWidget.screenNumber method.
class DbusWlp(Wallpaper):
def __init__(self, parent, args=None):
Wallpaper.__init__(self, parent)
# Plasmoid init code should go here
def init(self, config):
# also tried QX11Info but I think it's not relevant here
print QtGui.QX11Info().appScreen() # always returns 0
print QtGui.QApplication.desktop().screenNumber(self) # doesn't work because self is not QWidget subclass
print QtGui.QApplication.desktop().isVirtualDesktop() # returns True just in case
The main question is: What is the proper way to identify what screen plasma plugin(wallpaper or plasmoid) is running on? And a small additional question: Is there any better way to implement cross-widget communication then D-Bus?
I'm fairly new both to PyQT and PyKDE so I could easily missed something obvious and ANY help would be much appreciated. Thanks in advance!
PS: Sorry for my poor English - it's not my mother tongue.
