I am new to python and saw a source code regarding some inventory app made with tkinter and I got the hang of it modifying and trying to understand the code but there's something I cant seem to do, calculating the total price of the product(quantity * price). When i multiply the PRODUCT_QTY and PRODUCT_PRICE it returns 0 so I dont know how to asign the value to the tkinter variables IntVar().Here is the code of the viewform of the created products:
def ViewForm():
global tree
TopViewForm = Frame(viewform, width=600, bd=1, relief=SOLID)
TopViewForm.pack(side=TOP, fill=X)
LeftViewForm = Frame(viewform, width=600)
LeftViewForm.pack(side=LEFT, fill=Y)
MidViewForm = Frame(viewform, width=600)
MidViewForm.pack(side=RIGHT)
lbl_text = Label(TopViewForm, text="View Products", font=('arial', 18), width=600)
lbl_text.pack(fill=X)
lbl_txtsearch = Label(LeftViewForm, text="Search", font=('arial', 15))
lbl_txtsearch.pack(side=TOP, anchor=W)
search = Entry(LeftViewForm, textvariable=SEARCH, font=('arial', 15), width=10)
