为画布按钮创建具有 Tkinter 效果的操作

发布于 2025-01-17 07:20:40 字数 1513 浏览 1 评论 0原文

我正在关注是否可以有一个tkinter 中的垂直按钮？和如何在 tkinter 画布上创建按钮？作为在 Tkinter 画布上为按钮创建一些操作的指南？。这些操作有效，但 Button 的效果被冻结。

代码：

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()

如果我删除 canvas.bind("", lambda ev: Submit())，那么 Button 的效果就起作用了，但是有是提交操作。

否则，如果保留上面包含行 canvas.bind("", lambda ev: Submit()) 的代码，则 Button 的效果code> 已冻结，但 Submit 操作有效。

我正在寻找一种方法来使 Button 和 Submit 操作的效果一起工作。请帮我。谢谢。

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.

您需要在事件的第二个绑定上设置 add=True ，以便不会覆盖之前的绑定：

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

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
