Hi. I just installed opencv on ubuntu and when i created window with imshow() there are buttons and statistik. I was first surprised becuse in tutorials i have not seen these. Is there way to get rid of them? Other function which show just the image i want to? Or should i get used to them?

Edit: adding code and picture

code is simple:

#include<opencv2/opencv.hpp>

using namespace cv;

int main(){
    Mat img = imread("/home/test.jpeg",CV_LOAD_IMAGE_GRAYSCALE);
    imshow("test",img);
    waitKey(0);
    return 0;
}

window with picture looks like this:

Could you please post the _complete_ code you used and if possible a screenshot please? A priori, it seems like your code defines other behaviour before showing the image... Hard to tell without the code though

Your OpenCV was compiled with QT support so that you can use the enhanced interface. I really like it, but if you want to get rid of it, have a look at the flags when creating the window using cv::namedwindow

http://docs.opencv.org/modules/highgui/doc/user_interface.html

Just pass CV_GUI_NORMAL and you will get the old version.

Thank you. That is what i wanted. I must missed the Qt tags when looking in namedWindow function.

@Leir That is good it worked for you. On my side I hade to use the flag cv2.WINDOW_OPENGL instead to achieve your goal because this flag does not exist in my version. Can you tell me what version of OpenCV you use, please ?

"Can you tell me what version of OpenCV you use, please ?" I use the C++ Version of OpenCV...

by version I mean 2.4.10. or 3.0 or ...

but cv2.WINDOW_OPENGL is a python flag, so I assume you somehow mix the C++ and Python flags.
