I'm designing graphic editor. As a scene for drawing, I need to use exactly QGraphicsScene. I implemented adding rectangles and ellipses to the scene with two buttons.
I need to implement dragging the faigures from the panel to the canvas, approximately as in the picture:
What widgets or buttons can I use for this custom panel? Maybe there is an information an example with the implementation of a similar panel?
The program code with the implementation of adding shapes and the interface image:
`from PyQt5.QtWidgets import
from PyQt5.QtGui import
from PyQt5.QtCore import *
import sys
window class
class Window(QMainWindow):
def init(self):
super().init()
wid = QWidget()
self.setCentralWidget(wid)
# setting title
self.setWindowTitle("Paint with PyQt5")
# setting geometry to main window
self.setGeometry(100, 100, 800, 600)
# Defining a scene rect of 400x200, with it's origin at 0,0.
# If we don't set this on creation, we can set it later with .setSceneRect
self.scene = QGraphicsScene(0, 0, 400, 200)
# Set all items as moveable and selectable.
for item in self.scene.items():
item.setFlag(QGraphicsItem.ItemIsMovable)
item.setFlag(QGraphicsItem.ItemIsSelectable)
# Define our layout.
vbox = QVBoxLayout()
up = QPushButton("Rect")
up.clicked.connect(self.add_rect)
vbox.addWidget(up)
down = QPushButton("Elips")
down.clicked.connect(self.add_elips)
vbox.addWidget(down)
view = QGraphicsView(self.scene)
view.setRenderHint(QPainter.Antialiasing)
hbox = QHBoxLayout(self)
hbox.addLayout(vbox)
hbox.addWidget(view)
wid.setLayout(hbox)
def add_rect(self):
rect = QGraphicsRectItem(0, 0, 200, 50)
rect.setPos(50, 20)
rect.setFlag(QGraphicsItem.ItemIsMovable)
rect.setFlag(QGraphicsItem.ItemIsSelectable)
self.scene.addItem(rect)
def add_elips(self):
ellipse = QGraphicsEllipseItem(0, 0, 100, 100)
ellipse.setPos(75, 30)
ellipse.setFlag(QGraphicsItem.ItemIsMovable)
ellipse.setFlag(QGraphicsItem.ItemIsSelectable)
self.scene.addItem(ellipse)
