Oh , i changed my code to:

partial(self.myinstance.myfunc,[arg1,arg2,arg3,arg4,arg5],self.myinstance)

But i got the following traceback:
TypeError: myfunc() takes at least 5 arguments (4 given)
##############################3
myfunc() prototype is:
#########################
def myfunc(self,widget,projectFindInstance,field,data,checkBox =
None,lineEdit = None)
######################################

Note: My caller location in a class and myfunc is a method.

How can i use partial for this state?

Yours,
Mohsen
