Hello Plasma-Devel List! I have a Python script that I'm trying to turn into a Plasmoid. On a scale of 1-10 where 10 is the most proficient hacker, I am about a 1 or a 0.5 when it comes to GUI stuff. On top of that, there's the concept of data engines.
I based my data engine off of the Python Data engine tutorial:
(begin code)
from PyQt4.QtCore import *
from PyKDE4.kdecore import *
from PyKDE4 import plasmascript
#for flickr
import views
class PyFlickrEngine(plasmascript.DataEngine):
def __init__(self,parent,args=None):
plasmascript.DataEngine.__init__(self,parent)
def init(self):
self.setMinimumPollingInterval(333)
#for flickr
views.initialize()
def sourceRequestEvent(self, name):
print "source request event" #debugging
return self.updateSourceEvent(name)
def updateSourceEvent(self,group):
print "updateSourceEvent"
#grouplist = []
if group == "25":
print "i'm here"
grouplist = views.analyzeviews(views.views25)
#self.setData(grouplist, "Group List", QVariant.List) #original line
self.setData("25", "Group 25", grouplist)
elif group == "50":
grouplist = views.analyzeviews(views.views50)
self.setData("50","Group 50", grouplist)
elif group == "75":
grouplist = views.analyzeviews(views.views75)
self.setData("75","Group 75", grouplist)
return True
def CreateDataEngine(parent):
return PyFlickrEngine(parent)
(end code)
When I look at this in the Plasma Engine Explorer I see the following:
Datasource key Value Type
25
|_ Group List Not displayable PyQT_PyObject
Now, views.py, the program script it's calling is returning a tuple with the
first entry being an XML object and the second being a list.
So, first of all, it it right that the type on the data engine query is
"PyQT_PyObject"?
Second, how could I cobble together a quick script to grab from that
dataengine to be able to test the data coming out of there?
Third, is there a way to make the dataengine grab the data automatically?
Right now, when I use the Plasma Engine Explorer and type 25, 50, or 75, it
grabs the data. But this process takes a long time 5+ minutes or more. So
I'd like it to happen when the plasmoid starts, I guess. And I'd want it to
update all of them. So info on how to do that would be great as well.
Thanks in advance for the help.
