Creating actions for canvas Button with the effect on Tkinter-CodePudding

I'm following Is it possible to have a vertical-oriented button in tkinter? and How do you create a Button on a tkinter Canvas? as the guideline to create some actions for Button on a Tkinter Canvas?. The actions worked, but the effect of Button is frozen.

The code:

import tkinter as tk
import tkinter.font as tkfont
main = tk.Tk()
font = tkfont.nametofont("TkDefaultFont")
label = "Click Me"
height = font.measure(label)   4
width = font.metrics()['linespace']   4
canvas = tk.Canvas(main, height=height, width=width, background="SystemButtonFace", borderwidth=2, relief="raised")
canvas.create_text((4, 4), angle="90", anchor="ne", text=label, fill="SystemButtonText", font=font)

canvas.bind("<ButtonPress-1>", lambda ev: ev.widget.configure(relief="sunken"))
canvas.bind("<ButtonRelease-1>", lambda ev: ev.widget.configure(relief="raised"))
canvas.bind("<ButtonPress-1>", lambda ev: submit())

def submit():
    print("1")

canvas.place(x=5, y=height   10)
main.mainloop()

If I remove canvas.bind("<ButtonPress-1>", lambda ev: submit()), then the effect of Button worked, but there is Submit action.

Otherwise, If leave the code like above which contains the line canvas.bind("<ButtonPress-1>", lambda ev: submit()), then the effect of Button is frozen, but the Submit action works.

I'm looking for a way to have either the effect of Button and Submit action work together. Please help me. Thank you.

CodePudding user response：

You need to set add=True on the second bind of <ButtonPress-1> event, so that the previous binding is not override:

canvas.bind("<ButtonPress-1>", lambda ev: ev.widget.configure(relief="sunken"))
canvas.bind("<ButtonRelease-1>", lambda ev: ev.widget.configure(relief="raised"))
canvas.bind("<ButtonPress-1>", lambda ev: submit(), add=True) # added add=True
