Tkinter GUI tutorial in Python

Styling your GUI a bit using TTK





Now that we have a basic window set, we might have the urge to make it look a little better. Right now, our buttons especially are quite ugly. To do some minor updates to the graphics quite easily, we can make use of ttk.

To start, we need to import it:

from tkinter import ttk

Next, within our SeaofBTCapp:

class SeaofBTCapp(tk.Tk):

    def __init__(self, *args, **kwargs):
        
        tk.Tk.__init__(self, *args, **kwargs)

        tk.Tk.iconbitmap(self,default='clienticon.ico')
        tk.Tk.wm_title(self, "Sea of BTC Client")

While the above isn't about ttk, we're doing this to change the window icon, as well as the window's title.

Next, within our StartPage:

class StartPage(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self,parent)
        
        label = ttk.Label(self, text="Start Page", font=LARGE_FONT)
        label.pack(pady=10,padx=10)

        # change the tk to ttk

        button = ttk.Button(self, text="Visit Page 1",
                            command=lambda: controller.show_frame(PageOne))
        button.pack()

        # change the tk to ttk

        button2 = ttk.Button(self, text="Visit Page 2",
                            command=lambda: controller.show_frame(PageTwo))
        button2.pack()

Here, we are mainly just changin tk.Button to ttk.Button. That's just one example, but you should change all of your buttons from tk to ttk.

            self.frames[F] = frame

        button2 = ttk.Button(self, text="Page One",
                            command=lambda: controller.show_frame(PageOne))
        button2.pack()
        


app = SeaofBTCapp()
app.mainloop()
