Is it possible to loop through class attributes via string? - 04chiak - Feb-04-2018
Hey guys, I'm stumped on this issue.
I currently am referencing a UI file built in pyqt, and though it wise to create a while loop to iterate through the button commands. However, it seems to be pretty stubborn, and i'm not sure how to go about it.
iconEnumerator = 0 #This works, since there is a PoseSlot_32 attribute. The button slots go from 0-32 self.PoseSlot_32.clicked.connect(self.printonetwoThree2) #This doesn't work (looping) while iconEnumerator >= 32: "self.PoseSlot_" + str(iconEnumerator) + ".clicked.connect(self.printonetwoThree2)" iconEnumerator += 1what is difficult is that i've tried
#setAttr(self, "PoseSlot_32.clicked.connect()", self.printonetwoThree2)
stringPoseAttribute = "self.PoseSlot_" + str(iconEnumerator) + ".clicked.connect(self.printonetwoThree2)"
#eval(stringPoseAttribute)
and #getAttr Doesn't seem to be useful since it keeps returning invalid object

What is your actual purpose on doing this determines the result.
From the object of the class
>>> class Klass:
... def __init__(self):
... self.var = 1
... self.pot = 'test'
...
>>> obj = Klass()
>>> obj.__dict__
{'var': 1, 'pot': 'test'}

I'm currently trying to create a button gallery, however the button's functionality is triggered but a button attribute function. The reason for iteration through all these buttons. IE
self.PoseSlot_1.clicked.connect(self.printonetwoThree2)
self.PoseSlot_2.clicked.connect(self.printonetwoThree2)
self.PoseSlot_3.clicked.connect(self.printonetwoThree2)
self.PoseSlot_4.clicked.connect(self.printonetwoThree2)
...
is to create a default function on the click command if there is a null value.
I just figure I could make a loop so i didn't have to copy and paste the code like above
Oh yea also, All of the attributes are already generated through the UI file.* "PoseSlot_ ..."

Completely misunderstood the syntax of getAttr. Issue resolved
getattr(self, "PoseSlot_1").setIcon(QtGui.QIcon(self.jsonFolderPath + "/icon/" + self.jsonTemplateData.values()[0][0]["icon"]))
