我需要top才能創建tkinter畫布項目的副本,以便可以從原始圖像中拖出圖像的副本。我拖動圖像工作,但我似乎無法複製圖像項目。任何幫助將不勝感激!謝謝。複製Tkinter畫布項目
編輯:對不起,我的代碼一開始。由於給出的答案,我能夠解決問題。下面是我的代碼下調的例子,現在工作:
from tkinter import *
from PIL import Image, ImageTk
def OnBaseButtonPress(event):
#record the item and its location
drag_data["item"] = c.find_closest(event.x, event.y)
i = c.itemcget(drag_data["item"], "image") #finds the image source of the object
refs.append(i) #keep a reference!
c.create_image(c.coords(drag_data["item"]), image=i, tags="base") #creates an identical object at the position
drag_data["x"] = event.x
drag_data["y"] = event.y
def OnBaseButtonRelease(event):
#reset drag info
drag_data["item"] = None
drag_data["x"] = 0
drag_data["y"] = 0
def OnBaseMotion(event):
#calculate how far the item has moved
delta_x = event.x - drag_data["x"]
delta_y = event.y - drag_data["y"]
#move the object that amount
c.move(drag_data["item"], delta_x, delta_y)
#record the new position
drag_data["x"] = event.x
drag_data["y"] = event.y
#set up canvas and image
root = Tk()
c = Canvas(root, width=800, height=600)
c.pack()
test = ImageTk.PhotoImage(Image.open("test.png"))
c.create_image(400, 300, image=test, tags="base")
refs=[] #used to keep references to images used in functions
#bind mouse keys
c.tag_bind("base", "<ButtonPress-1>", OnBaseButtonPress)
c.tag_bind("base", "<ButtonRelease-1>", OnBaseButtonRelease)
c.tag_bind("base", "<B1-Motion>", OnBaseMotion)
drag_data={"x": 0, "y": 0, "item": None}
mainloop()
嗨faf。這個問題有點簡短和模糊。請儘可能地提供更多的資料。如果您要求提供代碼,請務必包含您已經嘗試過的代碼,以及爲什麼它不按您希望的方式工作。還請閱讀[寫出完美的問題](http://tinyurl.com/so-hints)。 –
顯示您的代碼。 – furas
