python - Start function on a button in frame tkinter -
i have code open frame. in main frame have button open frame2 (page01). on page01 button make call "function1" defined on top (and it's started when open program, don t want this) , in function1 want call function2 defined in page01.
code import tkmessagebox import tkinter tk tkinter import * functools import partial import ttk large_font= ("verdana", 12) def function1(): print "function 1 started" #function2() class changepages(tk.tk): def __init__(self, *args, **kwargs): tk.tk.__init__(self, *args, **kwargs) container = tk.frame(self) container.pack() container.grid_rowconfigure(0, weight=1) container.grid_columnconfigure(0, weight=1) self.frames = {} f in (mainpage, page01): frame = f(container, self) self.frames[f] = frame frame.grid(row=0, column=0, sticky="nsew") self.show_frame(mainpage) def show_frame(self, cont): frame = self.frames[cont] frame.tkraise() class mainpage(tk.frame): def __init__(self, parent, controller): tk.frame.__init__(self,parent) def c(*args): return partial(self.option_changed, *args) f = frame(self) f.pack(side='top') btnpage01=button(f,text='go pag 01',fg='blue',font=('helvetica',18),height=1, width=10,command=lambda: controller.show_frame(page01)) btnpage01.grid(row=1,column=1) class page01(tk.frame): def __init__(self, parent, controller): tk.frame.__init__(self, parent) f = frame(self) f.pack(side='left') def function2(): print "function 2 started" bttest = button(f,text='start f',fg='blue',font=('helvetica',26),height=1,width=10,command=function1() ) bttest.grid(row=1,column=1) #root loop app = changepages() app.geometry('300x200+0+0') app.title('title ') app.mainloop() so want : 1- open program - function1 should not start, neither function2 2- open page01 - function1 , 2 stopped 3- press start f , function1 should start , cal function2 start
