Im designing a gui in python. Im using tkinter. I have a clear function but for some reason I can only get it to work with my text boxes.

But Ive had trouble getting it to work with my radio buttons, checkboxes and list box. This is the code for them and my clear button and function.

#Variables for checkboxes

self.cb$1=$ tk$.$IntVar$()$

self.cb$2=$ tk$.$IntVar$()$

self.cb$3=$ tk$.$IntVar$()$

self.cb$4=$ tk$.$IntVar$()$

self.cb$1.$set$(0)$

self.cb$2.$set$(0)$

self.cb$3.$set$(0)$

self.cb$4.$set$(0)$

#Create checkboxes

self.serviceLabel $=$ tk$.$Label$($self$.$serviceF, text$=$"SERVICES$($Choose as many as needed$)",$ bg$=$"light green", font$=("$Impact$",14))$

self.cb$1$Var $=$ tk$.$Checkbutton$($self$.$serviceF, text$=$"Oil Change $-$ $$30\mathrm{.}00",$ bg$=$"light green", variable $=$ self.cb$1,$ command$=$self.Clear$)$

self.cb$2$Var $=$ tk$.$Checkbutton$($self$.$serviceF, text$=$"Radiator Flush $-$ $$40\mathrm{.}00",$ bg$=$"light green", variable $=$ self.cb$2,$command$=$self.Clear $)$

self.cb$3$Var $=$ tk$.$Checkbutton$($self$.$serviceF, text$=$"Inspection $-$ $$35\mathrm{.}00",$ bg$=$"light green", variable $=$ self.cb$3,$ command$=$self.Clear$)$

self.cb$4$Var $=$ tk$.$Checkbutton$($self$.$serviceF, text$=$"Tire Rotation $-$ $$20\mathrm{.}00",$ bg$=$"light green", variable $=$ self.cb$4,$ command$=$self.Clear$)$

self.serviceLabel.pack$()$

self.cb$1$Var.pack$($side$=$"left"$)$

self.cb$2$Var.pack$($side$=$"left"$)$

self.cb$3$Var.pack$($side$=$"left"$)$

self.cb$4$Var.pack$($side$=$"left"$)$

#Variable for radio buttons

self.rb $=$ tk$.$StringVar$()$

self.rb $=$ tk$.$IntVar$()$

self.rb$.$set$(0)$

#Create radio buttons

self.methodLabel $=$ tk$.$Label$($self$.$feeF, text$=$"SERVICE FEE$($Choose One$)",$ bg$=$"light blue", font$=("$Impat$",14,$ "bold"$))$

self.rb$1$Var $=$ tk$.$Radiobutton$($self$.$feeF, text $=$"Normal Service Fee $-$ $$15\mathrm{.}00",$ bg$=$"light blue", variable$=$self.rb$,$ value$=1,$ command$=$self.on$\_$select$)$

self.rb$3$Var.pack$($side$=$"left"$)$

#Below is the listbox

self.payLabel $=$ tk$.$Label$($self$.$payF, text$=$"Choose Method of Payment Below$($If other than cash$)",$ font$=("$Impact$",12),$ bg$=$"light yellow"$)$

self.listbox $=$ tk$.$Listbox$($self$.$payF$)$

#Populate the listbox

self.listbox.insert$(0,$ "Cash"$)$

self.listbox.insert$(1,$ "Check"$)$

self.listbox.insert$(2,$ "Visa"$)$

self.listbox.insert$(3,$ "MasterCard"$)$

self.payLabel.pack$()$

self.listbox.pack$()$

#Create action buttons

self.display.pack$()$

#$($side$="")$ must be top bottom left or right

self.quit.pack$()$

self.clear.pack$()$

#Start the main loop for the window

tk$.$mainloop$()$

def on$\_$select$($self$)$:

select$\_$option $=$ self.rb$.$get$()$

print$($f$"$Select option: $\{$select$\_$option$\}")$

def Clear$($self$)$: #Method called from the clear button

self.Entry$1.$delete$(0,$ 'end'$)$

self.Entry$2.$delete$(0,$ 'end'$)$
