My requirement is i need to drag an image to desired location. Based on the link board-drawing code to move an oval the following is the code snapshot i tried. I am not getting any errors its blank. Please let me know the way to take it forward.
import Tkinter as tk
from Tkinter import *
from PIL import ImageTk, Image
class Example(tk.Frame):
def __init__(self, parent):
tk.Frame.__init__(self, parent)
# create a canvas
self.canvas = tk.Canvas(width=400, height=400)
self.canvas.pack(fill="both", expand=True)
# this data is used to keep track of an
# item being dragged
self._drag_data1 = {"x": 0, "y": 0, "item1": None}
startframe = tk.Frame(root)
canvas = tk.Canvas(startframe,width=1280,height=720)
startframe.pack()
canvas.pack()
one = tk.PhotoImage(file=r'images/test1.gif')
root.one = one # to prevent the image garbage collected.
canvas.create_image((0,0), image=one, anchor='nw',tags="img1")
self.canvas.tag_bind("img1", "<1>", self.on_token_press1)
self.canvas.tag_bind("img1", "<1>", self.on_token_release1)
self.canvas.tag_bind("token", "<B1-Motion>", self.on_token_motion1)
def on_token_press1(self, event):
print("sss")
# record the item and its location
self._drag_data1["item1"] = self.canvas.find_closest(event.x, event.y)[0]
self._drag_data1["x"] = event.x
self._drag_data1["y"] = event.y
def on_token_release1(self, event):
# reset the drag information
self._drag_data1["item1"] = None
self._drag_data1["x"] = 0
self._drag_data1["y"] = 0
def on_token_motion1(self, event):
'''Handle dragging of an object'''
# compute how much the mouse has moved
delta_x = event.x - self._drag_data1["x"]
delta_y = event.y - self._drag_data1["y"]
# move the object the appropriate amount
self.canvas.move(self._drag_data1["item1"], delta_x, delta_y)
# record the new position
self._drag_data1["x"] = event.x
self._drag_data1["y"] = event.y
if __name__ == "__main__":
root = tk.Tk()
Example(root).pack(fill="both", expand=True)
root.mainloop()
