The code for this tutorial is [here](https://github.com/docPhil99/opencvQtdemo)

Opencv provides are useful, but limited, method of building a GUI. A much more complete system could be acheived using pyqt.
The question is, how do we display images. There are quite a few possible routes but perhaps the easiest is to use `QLabel` since it has a `setPixmap` function. Below is some code that creates two labels. It then creates a grey pixmap and displays it one of the labels. [code: staticLabel1.py](https://github.com/docPhil99/opencvQtdemo/blob/master/staticLabel1.py)

```python

from PyQt5.QtWidgets import QWidget, QApplication, QLabel, QVBoxLayout
from PyQt5.QtGui import QPixmap, QColor
import sys

def convert_cv_qt(self, cv_img):
        """Convert from an opencv image to QPixmap"""
        rgb_image = cv2.cvtColor(cv_img, cv2.COLOR_BGR2RGB)
        h, w, ch = rgb_image.shape
        bytes_per_line = ch * w
        convert_to_Qt_format = QtGui.QImage(rgb_image.data, w, h, bytes_per_line, QtGui.QImage.Format_RGB888)
        p = convert_to_Qt_format.scaled(self.disply_width, self.display_height, Qt.KeepAspectRatio)
        return QPixmap.fromImage(p)

Kırpma olaylarını halletmek için de pyqt5 teki event leri felan kurcalarsın diye düşünüyorum.

Bu da çözüm aslında, ama yukarıdaki daha pratik gibi geliyor bana. Ama denemedim kodu açıkçası

Bu arada anahtar kelime : pyqt5 and cv2 (Googlelamak için)
