I am getting an error alloc: invalid block: 047129A8: c0 4 when I add text to the canvas using create_text
Here is a sample program. If the create_text is removed clicking on the rectangle closes the progamme, but after adding text the programme closes but the error message appears and a popup window saying python has stopped working.
If I replace destroy() with quit(), it works fine.(Python 3.5)
import tkinter as TKclass Button(): def __init__(self): self.master = TK.Tk() canvas_width = 200 canvas_height =200 canvas = TK.Canvas(self.master, width=canvas_width, height=canvas_height) button = canvas.create_rectangle([10,10,110,30],fill='lightgrey') canvas.tag_bind(button, "<ButtonPress-1>", self.test) # lambda x: self.action(x,DOWN)) canvas.pack() canvas_id = canvas.create_text(10, 50, anchor="nw") canvas.itemconfig(canvas_id, text="this is the text") TK.mainloop() def test(self, e): print ('Clicked') #self.master.quit() self.master.destroy()if __name__ == '__main__': b = Button()
