Python: Dynamic attribute name generation without exec() or eval()
- by PyNewbie27
Hi,
I'm trying to dynamically create buttons at runtime with PyQT4.7
However, this being my first python program I'm not sure how to get the functionality I want.
I would like to be able to substitute a text string for an attribute name:
i.e.
for each in xrange(4):
myname = "tab1_button%s" % each #tab1_button0, tab1_button1, tab1_button2
#self.ui.tab1_button0 = QtGui.QPushButton(self.ui.tab) <--normal code to create a named button
setattr(self.ui,myname,QtGui.QPushButton(self.ui.tab)) #rewrite of line above to dynamicly generate a button
#here's where I get stuck. this code isn't valid, but it shows what i want to do
self.ui.gridLayout.addWidget(self.ui.%s) % myname
#I need to have %s be tab1_button1, tab1_button2, etc. I know the % is for string substituion but how can I substitute the dynamically generated attribute name into that statement?
I assume there's a basica language construct I'm missing that allows this. Since it's my first program, please take it easy on me ;)
