在 tkinter gui 中檢測同時左擊和右擊

Question

嘗試進行一些搜索，但無法得到答案，但是如果之前有人問過這個問題，請引導我到那個帖子。

我在 python 中有一個按鈕，並且希望將該按鈕綁定到 leftClick、rightClick 和 bothClick 函數。 bothClick 函數同時在按鈕 GUI 上單擊和/或釋放鼠標左右鍵。

我該怎么做bothClick？

還要綁定它，以便在觸發 bothClick 時它不會觸發 leftClick 和/或 rightClick。

注意：這類似於在掃雷中進行左鍵單擊、右鍵單擊並單擊兩個鼠標按鈕。

Answer 1

您可以實現如下。

使用兩個變量left_mouse_pressed和right_mouse_pressed 。 當兩者同時為True ，都按下了兩個鼠標鍵。

釋放鼠標時將其狀態重置為False 。

import Tkinter

class App:
    def __init__(self, root):
        self.root = root
        self.left_mouse_pressed = False
        self.right_mouse_pressed = False

        f = Tkinter.Frame(width=100, height=100, background="cyan")
        f.pack()

        f.bind("<Button-1>", self.onAnyofTwoPressed)
        f.bind("<Button-3>", self.onAnyofTwoPressed)

        f.bind("<ButtonRelease-1>", self.resetPressedState)
        f.bind("<ButtonRelease-3>", self.resetPressedState)

    def onAnyofTwoPressed(self, event):
        if event.num==1:
            self.left_mouse_pressed = True
        if event.num==3:
            self.right_mouse_pressed = True
        if (self.left_mouse_pressed and self.right_mouse_pressed):
            print 'yay both pressed'



    def resetPressedState(self, event):
            self.left_mouse_pressed = False
            self.right_mouse_pressed = False

root=Tkinter.Tk()
app = App(root)
root.mainloop()

只是tao示例的修改。

它打印left pressed ， right pressed和both pressed
但僅在釋放鼠標按鈕時-有時就足夠了。

import Tkinter
import time

class App:
    def __init__(self, root):
        self.root = root
        self.left_mouse_pressed = False
        self.right_mouse_pressed = False

        f = Tkinter.Frame(width=100, height=100, background="cyan")
        f.pack()

        f.bind("<Button-1>", self.onAnyofTwoPressed)
        f.bind("<Button-3>", self.onAnyofTwoPressed)

        f.bind("<ButtonRelease-1>", self.resetPressedState)
        f.bind("<ButtonRelease-3>", self.resetPressedState)

    def onAnyofTwoPressed(self, event):
        if self.left_mouse_pressed and self.left_mouse_pressed <= time.time():
            self.left_mouse_pressed = False

        if self.right_mouse_pressed and self.right_mouse_pressed <= time.time():
            self.right_mouse_pressed = False

        if event.num==1:
            self.left_mouse_pressed = time.time() + 500
        if event.num==3:
            self.right_mouse_pressed = time.time() + 500


    def resetPressedState(self, event):
        if self.left_mouse_pressed and self.right_mouse_pressed:
            print 'both pressed'
        elif self.left_mouse_pressed:
            print 'left pressed'
        elif self.right_mouse_pressed:
            print 'rigth pressed'

        self.left_mouse_pressed = False
        self.right_mouse_pressed = False

root=Tkinter.Tk()
app = App(root)
root.mainloop()

編輯：我的版本與after() -按下鼠標按鈕時打印

after() 300是“反應時間”。

import Tkinter as tk
import time

root = tk.Tk()

left_pressed = False
rigth_pressed = False

def on_left_click(event):
    global left_pressed, rigth_pressed

    if rigth_pressed:
        rigth_pressed = False
    else:        
        left_pressed = True

    root.after(300, on_left_later)

def on_left_later():        
    global left_pressed

    if left_pressed:
        left_pressed = False
        print "left pressed"
    else:
        print "both pressed"

def on_right_click(event):
    global left_pressed, rigth_pressed

    if left_pressed:
        left_pressed = False
    else:
        rigth_pressed = True

    root.after(300, on_right_later)

def on_right_later():
    global rigth_pressed

    if rigth_pressed:
        rigth_pressed = False
        print "rigth pressed"
#    else:
#        print "(right_do_nothing)"

button = tk.Button(root, text="Clik me! - left, right, both")
button.pack()
button.bind('<Button-1>',on_left_click)
button.bind('<Button-3>',on_right_click)

tk.mainloop()

Answer 3

self.bind("<Button-3>", lambda e:self.func())
