I am trying to implement an app to show image for 6s and then jump to another page with radio buttons to let them rate their own feeling about the images (give 15s for rating) and then show the next image. However, for counting down 15s, I used time.sleep() function, which make the program very slow for pressing radiobuttons (but my clicking, the button can still be pressed). I am wondering whether there is a way that the count down will not influence the program but just let the program jump to the next page when time up. Here is my code :
class SampleApp(tk.Tk):

tk.Tk.__init__(self, *args, **kwargs)
self.geometry('1800x970+15+5')

# the container is where we'll stack a bunch of frames
# on top of each other, then the one we want visible
# will be raised above the others
container = tk.Frame(self)
container.pack(side="top", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)

# put all of the pages in the same location;
# the one on the top of the stacking order
# will be the one that is visible.

Using time.sleep() in a tkinter program will make it unresponsive since it keeps the mainloop() from executing and able to respond to events.
To void that use the universal widget method after().
So, in your case use:
self.after(1000) # 1000 ms = 1 sec
instead of
time.sleep(1)
Here's some documentation I found about it.

I'm just learning Python and I don't know how to make this program to display result in label that I want and when I click button again I want to the new result replaces the previous one
I want to last class shows result in label or entry when i click 1st button and when i click it again the new result will replace previous.
This program is not finished yet. I don't want to write all code when i have problem with first function of program. Once I deal with this problem, writing the rest of the code will not be difficult

If you want to update an existing Label widget, declare a tk.StringVar() to store the label text, then bind that to your Label's textvariable attribute. Then your Label will automatically update whenever you set() the StringVar.
label_var = tk.StringVar(self, 'Default Value') # both of these args are optional
label = ttk.Label(self, textvariable=label_var) # instantiate Label and bind the var
To update the label:
label_var.set('New String Value')
When you grid()/pack()/place() your Label it will start with the text you gave the StringVar, if any.

Understand this is alot of code and considerably complex from most stackoverflow questions. If anyone can suggest/recommend another platform where I can get hands on help that would be appreciated as well.
I can tell you how to make this work, but this is a really bad design. Your second page is relying on data that was generated by the first page. You need a sensible way to do that communication. In the short term, if you add global x to your databrowser function, it will work.
At the very least, take databrowser out of PageOne.make_widget and make it a global function. You'll still need the global x statement, but at least it makes it clear that it's not private data.
I'm building my first app with Tkinter and I'm stuck with instance of class.
I followed this tutorial https://pythonprogramming.net/change-show-new-frame-tkinter/ but some questions remain :
- how does mean controller as argument for the init line in the differents class ?
- I would like to create instance of classA in classB and inversely but I'm getting wrong with arguments !
- About organisation code, I created 2 class (one for each frame) and writting function related in the good one, should I split them in a 3rd class ? What is the most convenient way ?
Actualy the code is running but I would like to add some setup tools in the 2nd window !
What do I must do to can modify some parameters in the SettingsPage Class and update and use them in the StartPage class ? For example I would like to modify ecartementlogo.
setp = SettingsPage(controller, StartPage) give me AttributeError: type object 'StartPage' has no attribute 'tk'
Sorry for posting all the code but I not sure about what can I remove for the example

This line used in the SettingsPage Class is ok : startp = StartPage(controller, SettingsPage)
I would say I need to write the reverse one but I having error with arguments (controller, StartPage) BUT this one setp = SettingsPage(controller, StartPage) don't work (in the init line of StartPage Class)
The issue is here:
class StartPage(tk.Frame):
# ... Omitting irrelevant stuff
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
setp = SettingsPage(controller, StartPage) # Right here
# ... More irrelevant stuff
You are passing the class StartPage to the SettingsPage, rather than an instance of that class. SettingsPage then tries to interpret the class as a widget, but a class is not a widget and does not have a tk attribute.
The best way to fix this is to remove that line, since you never use the variable setp. The corresponding line in SettingsPage.__init__ should also be removed.
You should also read the link suggested by #Brian Oakley. Your code currently has many issues. I have fixed one of them, and his link should help you fix more.
Before I post my code, this is not all of it but what I feel is relevant to my problem. The first class is run when the user clicks a button, so the class contents (the frame) is displayed. The handler for my frames is:
class Begin(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
# Creating the initial frame
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (LoginScreen, RegisterWindow, RevisionTopics, dataRep, reviseTen, FrameTwo):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
page_name = LoginScreen.__name__
self.frames[page_name] = frame
self.show_frame(LoginScreen) # Shows the page currently being interacted
Now, this is the frame which has the important function, 'start', which I need to run in my second frame.
First frame:
class reviseTen(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)

Second Frame:

self.optionThree = tk.Button(self, text="Option Three")
self.optionFour = tk.Button(self, text="Option Four")
self.question = tk.Label(self, text="What is the definition of: ")
# TRIED THIS - screen stays blank (but start method has code that makes the widgets appear
self.start(controller)
def start(self, controller):
self.reviseTen = reviseTen(self, controller)
I need start to complete the exact same functions as it did on the frame 'reviseTen', the function is running but just not doing anything to my second frame. It is just blank. The code for positioning the elements (so they show up) is meant to run after running start...
Is it to do with the way I called it?
Many thanks for any help.
Inherit reviseTen in your class instead of tk.Frame, and call the function with super:
class FrameTwo(reviseTen):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
self.optionOne = tk.Button(self, text="Option One")
self.optionTwo = tk.Button(self, text="Option Two")
self.optionThree = tk.Button(self, text="Option Three")
self.optionFour = tk.Button(self, text="Option Four")
self.question = tk.Label(self, text="What is the definition of: ")
super(FrameTwo, self).start(controller)
For more info on super, check out some of the answers to this question.
I'm trying a simple experiment, I have 3 frames, frame 1 has two labels - "for page 2" and "for page 3", it also has 2 radio buttons corresponding to the labels. based on which radio button is selected, when the user hits the next page button, I want the button to bring the user to the selected page
this is the code -
import Tkinter as tk
class MainApp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
# the main container that holds all the frames
container = tk.Frame(self)

container.grid_rowconfigure(0, weight = 1)
container.grid_columnconfigure(0,weight = 1)
self.frames = {}
# adding frames to the dictionary
for F in (Page1,Page2,Page3):
frame = F(container,self)
self.frames[F] = frame
frame.grid(row = 0, column = 0, sticky = "w")
self.show_frame(Page1)
def show_frame(self,page_name):
#SHOWS A FRAME WITH THE GIVEN NAME

frame.grid_remove()
frame = self.frames[page_name]
frame.grid()
#STACKING THE FRAMES
#frame = self.frames[cont]
#frame.tkraise()
class Page1(tk.Frame):
def __init__(self,parent,controller):
tk.Frame.__init__(self,parent)
lbl1 = tk.Label(self,text = "for page 2",font =("Helvetica",12,"bold"))
lbl1.grid(row=1,sticky="W")
lbl2 = tk.Label(self,text = "for page 3",font =("Helvetica",12,"bold"))
lbl2.grid(row=1,column=1,sticky="W")
btn1 = tk.Button(self, text="next page", font=('MS', 24, 'bold'))
btn1.grid(row=3,column = 0,columnspan=1)
#btn1['command'] = lambda: controller.show_frame(Page2)
self.var1 = tk.BooleanVar()
rButton1 = tk.Radiobutton(self,variable = self.var1,value=True)
rButton1.grid(row=2,sticky = "W")
rButton2 = tk.Radiobutton(self,variable = self.var1,value=False)
rButton2.grid(row=2,column=1,sticky = "W")
if self.var1.get() == 1:
btn1['command'] = lambda: controller.show_frame(Page3)
if self.var1.get() == 0:
btn1['command'] = lambda: controller.show_frame(Page2)
class Page2(tk.Frame):
def __init__(self,parent,controller):
tk.Frame.__init__(self,parent)
lbl = tk.Label(self,text="This is page 2",font=("Helvetica",12,"bold"))
lbl.pack()
class Page3(tk.Frame):
def __init__(self,parent,controller):
tk.Frame.__init__(self,parent)
lbl = tk.Label(self,text="This is page 3",font=("Helvetica",12,"bold"))
lbl.pack()
app = MainApp()
app.mainloop()
I assumed that by using a few basic conditions (located in my PageOne class) -
self.var1 = tk.BooleanVar()
rButton1 = tk.Radiobutton(self,variable = self.var1,value=True)
rButton1.grid(row=2,sticky = "W")
rButton2 = tk.Radiobutton(self,variable = self.var1,value=False)
rButton2.grid(row=2,column=1,sticky = "W")
if self.var1.get() == 1:
btn1['command'] = lambda: controller.show_frame(Page3)
if self.var1.get() == 0:
btn1['command'] = lambda: controller.show_frame(Page2)
I would be able to achieve this, but it doesn't seem to work. The conditions in my if statements are integers but to my knowledge 1 represents True and 0; False anyway? what am i doing wrong?
I think this is what you want. I didn't handle making sure the radiobutton isn't selected by default. I left that as an exercise to you. Although, if you're wanting to just switch pages like this I'd just use buttons (tk/ttk.Button), then you don't have to worry about handling the radiobutton. Although, that's just my preference either will work fine of course. You can just bind each button to switch the page. I commented the buttons out in your modified code below.
If you're wanting to create buttons / radiobuttons to have a forward / back option for each page. You can just iterate over the controllers frames to see which is the current, and create two buttons similar to the ones below to move to the other frames.
