## Requirements

* PyQt5 >= 5.8

## Feature

* Being able to drag and drop horizontal border vertically

* Pressing mouse cursor to place more adjacent border on the spot.

* Right click to release the focus of the box

## Example

Code Sample

```python

from PyQt5.QtWidgets import QWidget, QGridLayout, QApplication, QPushButton, QFileDialog

from pyqt_vbounding_box.vBoundingBox import VBoundingBox

class VBoundingBoxExample(QWidget):

    def __init__(self):

        super().__init__()

        self.__initUi()

    def __initUi(self):

        addImageBtn = QPushButton('Add image')

        addImageBtn.clicked.connect(self.__addImage)

        self.__view = VBoundingBox()

        lay = QGridLayout()

        lay.addWidget(addImageBtn)

        lay.addWidget(self.__view)

        self.setLayout(lay)

    def __addImage(self):

        filename = QFileDialog.getOpenFileName(self, 'Open', '', 'Image Files (*.png *.jpg *.bmp)')

        if filename[0]:

            filename = filename[0]

            self.__view.setFile(filename)

if __name__ == "__main__":

    import sys

    app = QApplication(sys.argv)

    ex = VBoundingBoxExample()

    ex.show()

    sys.exit(app.exec_())

```
