PRNG, python. 1 button – 2 function?

Question

help me please. It is necessary that when the ‘Generate’ button(gen) is pressed, 2 functions (clicked1, gen1) are executed. But it only run clicked1.

I read that I can use lambda; or create a separate function that includes the ones you need. But gen1 still fails.
but the most important thing is that
when I removed clicked1 from the code completely, then gen1 didn’t work either(

        self.lb1 = Label(self.window, text="Enter:", background='#FFF5EE', font = ("Comic Sans MS", 14))  
        self.lb1.grid(column=0, row=2)

        except ValueError:

        else:

                        while i < Num:
                                numOne = randint(MinNum, MaxNum)
                                Nums = Nums + ' ' + str(numOne)
                                i += 1
                        self.scrolltxt.delete(1.0, END) 
                        self.scrolltxt.insert(INSERT, str(Nums) + "n") 
                else:
                        messagebox.showerror("Error", "Please enter correct numbers!")
        
    def delete(self):
        self.scrolltxt.delete(1.0, END)

        self.image = Image.open("C:\Users\ПК\OneDrive\Рабочий стол\лб1\11.png")  
        self.photo = ImageTk.PhotoImage(self.image)
        self.canvas.grid(row=0,column=4)
        self.image = self.canvas.create_image(0, 0, anchor='nw',image=self.photo)
    
app= App()

I don’t understand what I’m doing wrong
I hope I explained the problem clearly

Answer 1

Both the clicked1() and gen1() are executed when the Generate button is clicked. However nothing will be inserted into the text box because the text box is disabled.

You need to enable the text box before inserting text and disabled it back after:

self.scrolltxt.config(state="normal") # enable the text box
self.scrolltxt.delete("1.0", END) # better use "1.0" instead of 1.0 
self.scrolltxt.insert(INSERT, str(Nums) + "n")
self.scrolltxt.config(state="disabled") # disable the text box
