Visualize button is not working

[niranjanreddy891]

import tkinter as tk
from tkinter.filedialog import askopenfilename

    visual = pcl.pcl_visualization.CloudViewing()

    # filtering ground points
    print(cloud.size)

    fil = cloud.make_passthrough_filter()
    fil.set_filter_field_name("z")
    fil.set_filter_limits(0, 1.5)
    cloud_filtered = fil.filter()

    print(cloud_filtered.size)

###### visualization
    visual.ShowColorCloud(cloud, b'cloud')

    flag = True
    while flag:
        flag != visual.WasStopped()
    end

root.mainloop()

There's one thing that always works when debugging stuff... make a copy of the code, remove some feature, try to run the code and keep going until you find the problem. Now your code contains lots of stuff that has nothing to do with whatever your actual problem is. It could be worse, but I'm sure you can make this more minimal.

Hmm... here's your problem.

def processbutton():
  global bro
  bro=processbutton()

visualize() has the same problem.

I'm not sure why you are doing this, but this is very probably not what you want. My tutorial contains nothing like this.

Thanks for the reply @Akuli. My requirement is "User will select a file from browse button and when he clicks visualizebutton, visualization should start". Can you help me in this issue. I am a bit confused.

Maybe it's best if you come to an actual chat where I can answer questions much faster than on github? I'm often on the ##learnpython IRC channel on freenode.

Anyway, the error has nothing to do with tkinter and it's saying that you should do pcl.load_XYZRGB(something) instead of just pcl.load_XYZRGB().

I guess we're done here. If I'm on the chat I linked, just ask me there; if I'm not, you can also ask here on github.
