Tkinter Buttons

[pythonNerd159]

Does anyone know the code to click a button widget and get the value of that button to show up on an entry screen. I'll show you my code.

class Application(Frame):
    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.grid()
        self.createEdit()
        self.createView()
        self.createHelp()
        self.createQuit()
        self.createOnOff()
        self.createDelete()
        self.createClear()
        self.createSeven()
        self.createEight()
        self.createNine()
        self.createDivide()
        self.createFour()
        self.createFive()
        self.createSix()
        self.createTimes()
        self.createOne()
        self.createTwo()
        self.createThree()
        self.createMinus()
        self.createZero()
        self.createNegative()
        self.createDecimal()
        self.createPlus()
        self.createEquals()





## Buttons at top of window, adjust to suit proper format

## Last part




        
app = Application()
app.master.title("Extreme Calculator") # This will be the name of the window
app.mainloop()

If you know the code reply ASAP and much thanks

You need to bind each button to an event handler and then append the Entry box's text in each handler according to what button was pressed.

alright man, but could you give me an example of the code to kind of head in the right direction!!

Following is an example where I already have defined a list of text strings (self.btnList) to be displayed on buttons. When a button is selected (actually, the sequence is ButtonRelease), the button text is assigned to instance attribute "value" and the app is destroyed. In your case, you want to "set" the value of the string variable (Tkinter.StringVar) that was assigned to an entry widget textvariable.

def singleChoice(self, parent):
        # Create button frame and buttons
        self.buttonFrame = Tkinter.LabelFrame(parent, text="Available options", labelanchor="n")
        self.buttonFrame.config(relief="ridge", bd=3)
        self.buttonFrame.grid()
        self.value = None
        self.buttonList = []
        j=-1
        for i, t in enumerate(self.btnList):
            btn = Tkinter.Button(self.buttonFrame,
                                 text=t,
                                 anchor='center',
                                 bd=3,
                                 bg='#ffffff000',
                                 fg="#000000fff",
                                 activebackground = "#000000fff",
                                 activeforeground = "#ffffff000",
                                 font=textFont3,
                                 padx='1.0m',
                                 pady='1.0m',
                                 relief='raised',
                                 state='normal',
                                 width=self.btnWidth)
            self.buttonList.append((btn, t))
            if not i%self.columns:
                j += 1
            btn.grid(row=j, column=i%self.columns)
            def handler(event, i=i):
                return self.__buttonHandler(event, i)
            btn.bind(sequence="<ButtonRelease-1>", func=handler)
    
    def __buttonHandler(self, event, btnNumber):
        setattr(self, 'value', self.buttonList[btnNumber][1])
        self.destroy()
