Argument cannot work in Spyder 2.3.4

[ghost]

Description

I have some problems about argument after I installed spyder 2.3.4. The argument in console cannot work when you type function or create objective.

• What steps will reproduce the problem?

For example, if I create a function as below:

def f(x, alpha = 3, beta =2):
    return 3*x + beta

• What is the expected output? What do you see instead?

Expected: Previously in Spyder 2.3.1, when I type f( in ipython console or editor, spyder will automatically showed argument (x, alpha =3, beta =2).

What I see now: In Spyder 2.3.4, the argument only showed ( , =, =).

• Please provide any additional information below

I use Ubuntu 14.04. I hope the argument can work as before and showed all input.

I think what you're seeing is the same problem as reported in issue #2036. Could you confirm it?

Hi:

I also have the problems reported in Issue #2036 too.

My problem is the function argument disappeared. As you can see in the attached graph, in previous Spyder version, there should be (x, alpha) in the argument part. However, Spyder 2.3.4 only showed ( , ).

Yes, it's exactly the same problem. The only solution right now is to change your windows style in

Tools > Preferences > General > Qt windows style

and choosing a different option than the default one, which is GTK+
