Hello guys 👋 yjg30737 here

I currently work as a server-side developer, but in my spare time, I'm working on the side project such as my beloved "pyqt-openai," which focuses on AI-related PyQt and PySide GUI software.

Python-based GUI toolkits like PyQt and PySide have tremendous potential, especially since many AI packages such as PyTorch, TensorFlow, OpenAI, and Hugging Face utilize Python. With these toolkits, you can easily create GUIs for those packages. Personally, I find it enjoyable to create my own version of a chatbot using Python GUI software.

If you're interested in both PyQt and AI, feel free to join the pyqt-ai Discord channel. You can ask any questions related to the latest AI technology and PyQt. Additionally, I'll be glad to share the latest articles with all of you 🙂.

How to implement a custom menu for selecting and dragging shapes from there to QGraphicsView for a graphic editor?

``I am trying to implement a graphic editor. As a canvas for drawing, I use QGraphicsScene together with QGraphicsView.

There was a problem with the implementation of the panel, which is essentially a menu of shapes, from where it would be possible to drag shapes to QGraphicsView. It is located outside of QGraphicsView.
I would also like this menu to be divided into several sections so that they can be opened and closed by a button.

Is there an example of implementing this custom shapes menu? Or maybe thoughts with which it can be implemented?

This gif is the example of how I would like it to work (I use drawio as an example):

My code:
`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)

create pyqt5 app

App = QApplication(sys.argv)

create the instance of our Window

window = Window()

showing the window

window.show()

start the app

sys.exit(App.exec())`
