So basically I have made a custom widget to be populated in QListWidget using this method: https://stackoverflow.com/a/49272941/7020404
I am working on this project:
Whenever I clicked the Add to Chart button, I want the button will be disabled (I have made it) and I will have this custom widget item will be in the QListWidget's chart. But When I click the Cabbage's Add to Cart button, I got the Pork in the cart instead of Cabbage.
The cart:
I have 3 Tabs which are Food, Drink, and Chart. Each of the tabs has a class named TabFood, TabDrink, and TabCart.
Basically, I already have foodMenuList (A list of MenuWidget).
My MenuWidget Class:
class MenuWidget(QWidget):
def __init__(self, id, image, name, price, availability, sellerID):
super().__init__()
self.id = id
self.image = image
self.name = name
self.price = price
self.availability = availability
self.sellerID = sellerID
self.imageLabel = QLabel()
self.imageLabel.setPixmap(self.image)
self.nameLabel = QLabel()
self.nameLabel.setText(self.name)
self.priceLabel = QLabel()
self.priceLabel.setText("Rp " + str(price))
self.availabilityLabel = QLabel()
if self.availability:
self.availabilityLabel.setText("Ready")
else:
self.availabilityLabel.setText("Out of Stock")
self.vbox = QVBoxLayout()
self.vbox.addWidget(self.nameLabel)
self.vbox.addWidget(self.availabilityLabel)
self.vbox.addWidget(self.priceLabel)
self.hbox = QHBoxLayout()
self.addToCartButton = QPushButton("Add To Cart")
self.hbox.addWidget(self.imageLabel)
self.hbox.addLayout(self.vbox)
self.hbox.addWidget(self.addToCartButton)
self.setLayout(self.hbox)
This my TabFood Code:
class TabFood (QWidget):
def __init__(self, tabCart):
super().__init__()
self.hbox = QHBoxLayout()
# Create the list
self.mylist = QListWidget()
self.mylist.show()
self.hbox.addWidget(self.mylist)
self.setLayout(self.hbox)
for food in foodMenuList:
# Add to list a new item (item is simply an entry in your list)
item = QListWidgetItem(self.mylist)
self.mylist.addItem(item)
# Instanciate a custom widget
food.addToCartButton.clicked.connect(lambda: self.addToCart(tabCart, food)) ##tabCart is the instance of TabCart class (Just like a TabFood Class)
item.setSizeHint(food.minimumSizeHint())
# # Associate the custom widget to the list entry
self.mylist.setItemWidget(item, food)
def addToCart(self, tabcart, item):
self.sender().setEnabled(False)
print(item.name) ##This always return pork instead of cabbage
itemNew = OrderWidget(item.id, item.image, item.name, item.price, item.availability, item.sellerID)
tabcart.addItem(itemNew) ##It is only a function to add item in tabcart's QListWidget
I think the problem is in this line:
food.addToCartButton.clicked.connect(lambda: self.addToCart(tabCart, food))
Because in the addToChart function, when I print the item.name , it always prints pork instead of cabbage. But I am not sure because I have provided the food as the parameter in the iteration to determine which item has been selected.
So How Can I fix this problem?
