place() 相對定位與絕對定位 相對定位 拖動會發生變化 絕對定位不會
from tkinter import *
root = tk()
# absolute positioning
button(root,text="absolute placement").place(x=20, y=10)
# relative positioning
button(root, text="relative").place(relx=0.5, rely=0.2, relwidth=0.5,
width=10, anchor = ne)
root.mainloop()
from tkinter import *
root = tk()
label(root, text='click at different\n locations in the frame below').pack()
def mycallback(event):
print dir(event)
print "you clicked at", event.x, event.y
#event.x event.y 橫座標縱座標
myframe = frame(root, bg='khaki', width=130, height=80)
myframe.bind("", mycallback)
#button-1是滑鼠左擊
#按下滑鼠b
##keyboard press of alt + ctrl + delete
myframe.pack()
root.mainloop()
myframe.bind("", mycallback)繫結事件
注意點：an event type (required): some common event types include button,
buttonrelease, keyrelease, keypress, focusin, focusout, le**e (mouse le**es
the widget ), and mousewheel.
an event modifier (optional): some common event modifiers include alt, any (used
like in ), control, double (used like in to
denote a double-click of the left mouse button ), lock, and shift
常用事件繫結
from tkinter import *
root = tk()
label(root, text='click at different\n locations in the frame below').pack()
def callback(event):
# print dir(event)
print "you clicked at", event.x, event.y
widget = frame(root, bg='khaki', width=130, height=80)
widget.bind("",callback) #bind widget to left mouse click
widget.bind("", callback) # bind to right mouse click
widget.bind("", callback)# bind to return(enter) key
widget.bind("", callback) #bind to focus in event
widget.bind("", callback)# bind to keypress a
widget.bind("", callback)# bind to capslockkeysym
widget.bind("", callback)# bind widget to f1 keysym
widget.bind("", callback)# bind to keypad number 5
widget.bind('', callback) # bind to motion over widget
widget.bind("", callback) # bind to any keypress
widget.pack()
root.mainloop()
