Tkinter - Inserting text into canvas windows
First, lets get the terminology straight: you aren't creating widgets, you're creating canvas items. There's a big difference between a Tkinter text widget and a canvas text item.
There are two ways to set the text of a canvas text item. You can use itemconfigure to set the text attribute, and you can use the insert method of the canvas to insert text in the text item.
In the following example, the text item will show the string "this is the new text":
import Tkinter as tkclass Example(tk.Frame): def __init__(self, *args, **kwargs): tk.Frame.__init__(self, *args, **kwargs) canvas = tk.Canvas(self, width=800, height=500) canvas.pack(side="top", fill="both", expand=True) canvas_id = canvas.create_text(10, 10, anchor="nw") canvas.itemconfig(canvas_id, text="this is the text") canvas.insert(canvas_id, 12, "new ")if __name__ == "__main__": root = tk.Tk() Example(root).pack(side="top", fill="both", expand=True) root.mainloop()
