# pyqt-bounding-box
PyQt bounding box for graphic design software
## Requirements
PyQt5 >= 5.8
## Setup
`python -m pip install pyqt-bounding-box`
## Feature
* Cursor shape changes properly for position (horizontal/vertical edge, etc.)
* Being able to resize the box horizontally/vertically/diagonally
* Being able to move the box with either mouse cursor or arrow keys
* Being able to change the attribute of the box
## Methods Overview
* setLineWidth(self, n: int) - Default width is 3
* setColor(self, color: QColor) - Default color is black
* setStyle(self, style: Qt.PenStyle) - Default style is Qt.DashLine (You can see more about this style in here)
* setWidth(width: int)
* setHeight(height: int)
* setSize(width: int, height: int)
You can use the standard function like `setPen(pen: QPen)` if you know how to use it, Here's the example:
```python
item = BoundingBox()
pen = QPen()
pen.setStyle(Qt.DashLine)
pen.setWidth(3)
pen.setColor(QColor(0, 0, 0))
item.setPen(pen)
```
## Example
Code Sample
```python
from PyQt5.QtWidgets import QWidget, QGraphicsView, QVBoxLayout, QApplication, QGraphicsScene
from pyqt_bounding_box.boundingBox import BoundingBox
class Example(QWidget):
def __init__(self):
super().__init__()
self.__initUi()
def __initUi(self):
view = QGraphicsView()
self.__scene = QGraphicsScene()
self.__scene.setSceneRect(0, 0, 400, 400)
item = BoundingBox()
# item.setLineWidth(8) If you want to change the edge line width, add the code.
# item.setColor(QColor(255, 255, 255)) If you want to change the color of the line to white, add the code.
# item.setStyle(Qt.SolidLine) If you want to change the style of line from dashed to solid line, add the code.
self.__scene.addItem(item)
view.setScene(self.__scene)
lay = QVBoxLayout()
lay.addWidget(view)
self.setLayout(lay)
if __name__ == "__main__":
import sys
app = QApplication(sys.argv)
example = Example()
example.show()
app.exec_()
```
