[英]tkinter left clicks on a TAB in your GUI. How to detect when user has done this
[英]Detect simultaneous left and right clicks in tkinter gui
尝试进行一些搜索,但无法得到答案,但是如果之前有人问过这个问题,请引导我到那个帖子。
我在 python 中有一个按钮,并且希望将该按钮绑定到 leftClick、rightClick 和 bothClick 函数。 bothClick 函数同时在按钮 GUI 上单击和/或释放鼠标左右键。
我该怎么做bothClick?
还要绑定它,以便在触发 bothClick 时它不会触发 leftClick 和/或 rightClick。
注意:这类似于在扫雷中进行左键单击、右键单击并单击两个鼠标按钮。
您可以实现如下。
使用两个变量left_mouse_pressed
和right_mouse_pressed
。 当两者同时为True
,都按下了两个鼠标键。
释放鼠标时将其状态重置为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
但仅在释放鼠标按钮时-有时就足够了。
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()
编辑:我的版本与after()
-按下鼠标按钮时打印
after()
300是“反应时间”。
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()
self.bind("<Button-3>", lambda e:self.func())
