所以,这些是我创建/绘制的线条:
from tkinter import *
root = Tk()
f= Frame(root)
f.pack()
c = Canvas(f,bg = "black")
c.pack()
line1 = c.create_line(10,0,10,50,fill = "white",activefill = "blue",tag = "one")
line_side1 = c.create_line(0,25,10,25,fill= "white", activefill = "blue",tag = "one")
line2 = c.create_line(30,0,30,50,fill = "white",activefill = "blue",tag = "one")
line_side2 = c.create_line(30,25,40,25,fill= "white", activefill = "blue",tag = "one")
c.pack()
root.mainloop()
所以,现在我希望当我将鼠标悬停在它们上面时,所有的线都应该变成蓝色。
我试过使用 tag_bind
选项,但如果您能告诉我如何操作,将会很有帮助。
最佳答案
虽然@AleksanderMonk 的回答很好,但我认为在这种情况下绑定(bind)到标签 "one"
会更容易,尤其是当您计划制作更多行时。您可以在 tag_bind
和 itemconfigure
函数中使用标签而不是 id:
from tkinter import *
def change_color(event):
if event.type == "7": # Enter
event.widget.itemconfigure("one", fill="blue")
elif event.type == "8": # Leave
event.widget.itemconfigure("one", fill="white")
root = Tk()
f = Frame(root)
c = Canvas(f, bg="black")
f.pack()
c.pack()
line1 = c.create_line(10, 0,10,50, fill="white", tag="one")
line_side1 = c.create_line( 0,25,10,25, fill="white", tag="one")
line2 = c.create_line(30, 0,30,50, fill="white", tag="one")
line_side2 = c.create_line(30,25,40,25, fill="white", tag="one")
c.tag_bind("one", "<Enter>", change_color)
c.tag_bind("one", "<Leave>", change_color)
root.mainloop()
