[Solved]Multiply a number to a DoubleSpinBox - Extra - May-21-2022 Hello, I'm trying to make a sellPrice variable that takes in the user's input from the Price Input that I have and multiplies 1.10 to it. This is a snippet of my PriceInput: self.PriceInput = QtWidgets.QDoubleSpinBox(self.centralwidget) self.PriceInput.setStyleSheet("background-color: rgb(255, 255, 255);") self.PriceInput.setObjectName("PriceInput") self.formLayout_2.setWidget(5, QtWidgets.QFormLayout.FieldRole, self.PriceInput)And these are the variables I have that store the user's input: #Store the user's inputs ItemName = self.NameInput.text() Quantity = self.QuantityInput.text() Price = self.PriceInput.text() Description = self.DescriptionInput.toPlainText() Category = self.CategoryInput.currentText() Location = self.LocationInput.text() Barcode = self.BarcodeInput.text() Length = self.spinBox.value() sellPrice = Price * 1.10 mylist = [ItemName, Quantity, Price, sellPrice, Description, Category, Location, Length, Barcode]If I try to run my code: How do I fix this?Thanks in advance.

I do have one more question though. I'm trying to delete a row from the Table and I got it to delete from the InventoryDisplay (the table on the screen), but when I click my refresh button the row I "deleted" pops back up. (I delete the rows by clicking the small number at the side of the table which highlights the whole row and then I click my delete button) How do I get it so it actually deletes the row from the SQLite table and not just the screen? Here's what I have so far: #---------------------------------- #RemoveItem Function def RemoveItemClicked(self): #Print in terminal for testing: print("The Delete Item Button was clicked") #Delete

was really deleted in inventory.db? RE: Multiply a number to a DoubleSpinBox - Extra - May-22-2022 It was not really deleted in inventory.db. I think it has something to do with my DELETE FROM statement because I don't think I'm grabbing the index/row properly from the InventoryDisplay table on my screen/GUI and telling SQLite to delete it correctly. RE: Multiply a number to a DoubleSpinBox - Axel_Erfurt - May-22-2022 If you work with sqlite you should use QtSql.QSqlTableModel() preferably with QTableView. Then you can delete a row and the database will be updated automatically. RE: Multiply a number to a DoubleSpinBox - Extra - May-22-2022 Just out of curiosity, is there a way to get the row number (the small numbers on the QtTable) that way I could set the Item's Id to the row number so if I were to delete the row the items below it would have their Id's subtracted by 1 to compensate for the deleted row? Or how do I get/store the item's id from the id column on the Table when it's selected? And thanks for the input. I'll start looking into QtSql.QSqlTableModel() and hopefully I can get it to work.. RE: Multiply a number to a DoubleSpinBox - Extra - May-22-2022 Got it. I'm now able to delete a selected row. This is what I did: #RemoveItem Function def RemoveItemClicked(self): #Print in terminal for testing: print("The Delete Item Button was clicked") #Delete Items from the Inventory index = self.InventoryDisplay.currentIndex() NewIndex = self.InventoryDisplay.model().index(index.row(), 0) print('Index is :',NewIndex) indexID = self.InventoryDisplay.model().data(NewIndex) print(indexID) connection = sqlite3.connect("inventory.db") cursor = connection.cursor() cursor.execute("DELETE FROM items WHERE id = ?", (indexID,)) connection.commit() connection.close() RE: [Solved]Multiply a number to a DoubleSpinBox - Axel_Erfurt - May-23-2022 That's an example for QtSql create Database from PyQt5.QtSql import QSqlQuery, QSqlDatabase from PyQt5.QtWidgets import QMessageBox, QApplication, qApp def createDB(): db = QSqlDatabase.addDatabase('QSQLITE') db.setDatabaseName('inventory2.db') if not db.open(): QMessageBox.critical(None, qApp.tr("Cannot open database"), qApp.tr("Unable to establish a database connection.\n" "This example needs SQLite support.

Thanks. I do have one more questions though: (1) I got the QsqlTableView formatted to my GUI but now there's a gray box in the top left corner of the screen/GUI under the Window/App name and I don't know what it is, or how it got there (I have attached a screenshot of the GUI/Screen). Why is that there and how do I get rid of it? Thanks again.
