내 질문에 어리 석거나 까다로운 질문인지 모르겠습니다.Tkinter Canvas : 움직이는 물체의 축척
그래서 Tkinter와 Canvas를 사용하여이 게시물 Move and zoom a tkinter canvas with mouse 덕분에 완벽하게 작동하는 스크롤/확대/축소 기능을 구현하는 데 성공했습니다. 또한 창 크기가 문제없이 변경되면 캔바스 크기의 크기를 조정하는 바인딩을 추가합니다.
coords 및 after을 사용하면 object으로 이동할 수 있습니다.
모든 것을 결합하려고 할 때 문제가 발생했습니다.이

- 스크롤 및 확대를). 내가 볼 수있는 문제는 스케일링에서 왔는데, 어쩌면 객체의
coords이 변경되어 캔버스 크기 조정을 유도 한 다음 스케일을 사용하지 않도록 설정할 수 있습니까? 그렇다면이 문제를 해결하는 데 도움이 필요합니다. 그렇지 않은 경우 문제를 발견하는 데 도움이 필요합니다 ...self.master.after(50, self.Display)을 제거/비활성화하면 더 이상 움직이지 않습니다.import Tkinter as tk import math class Example: def __init__ (self, master): self.master = master self.interval = 0 self.SizeX, self.SizeY = master.winfo_width(), master.winfo_height() #Canvas Frame self.SystemCanvasFrame = tk.Frame(master, bg='black') self.SystemCanvasFrame.grid(row=0, column=0) #Canvas self.SystemCanvas = tk.Canvas(self.SystemCanvasFrame, width=int(self.SizeX*0.75)-20, height=self.SizeY-20, bg="black") self.SystemCanvas.focus_set() self.xsb = tk.Scrollbar(self.SystemCanvasFrame, orient="horizontal", command=self.SystemCanvas.xview) self.ysb = tk.Scrollbar(self.SystemCanvasFrame, orient="vertical", command=self.SystemCanvas.yview) self.SystemCanvas.configure(scrollregion=(-500,-500,500,500)) self.SystemCanvas.configure(yscrollcommand=self.ysb.set, xscrollcommand=self.xsb.set) #add the canvas with scroll bar in grid format self.xsb.grid(row=1, column=0, sticky="ew") self.ysb.grid(row=0, column=1, sticky="ns") self.SystemCanvas.grid(row=0, column=0, sticky="nsew") # This is what enables using the mouse to slide the window: self.SystemCanvas.bind("<ButtonPress-1>", self.move_start) self.SystemCanvas.bind("<B1-Motion>", self.move_move) #windows scroll self.SystemCanvas.bind("<MouseWheel>",self.zoomer) #resize the main window self.master.bind('<Configure>', self.UpdateCanvasSize) #Create Objects self.Size = 5 #object Size x0 = 0 y0 = 0 x1 = self.Size y1 = self.Size self.SystemCanvas.create_oval(x0,y0,x1,y1, fill='green', outline='green', width=3, tags='Green') self.SystemCanvas.create_oval(x0,y0,x1,y1, fill='red', outline='red', width=3, tags='Red') self.SystemCanvas.create_oval(x0,y0,x1,y1, fill='yellow', outline='yellow', width=1, tags='Yellow') self.Display() def Display(self): self.interval += 0.5 #speed parameter GreenPos = self.UpdatePosition(0.1*self.interval, (0,0), 50) RedPos = self.UpdatePosition(0.02*self.interval+180, (0,0), 200) YellowPos = self.UpdatePosition(0.3*self.interval, RedPos, 10) self.MoveObject('Green', GreenPos) self.MoveObject('Red', RedPos) self.MoveObject('Yellow', YellowPos) self.master.after(50, self.Display) #Disable to zoom def MoveObject (self, Obj, pos): #only move object that are in the field of view """Move Obj to the given position (tuple - xy)""" ID = self.SystemCanvas.find_withtag(Obj) #Convert the Center of the object to the coo need for tk x0 = pos[0] - self.Size/2.0 #radius of the circle y0 = pos[1] - self.Size/2.0 x1 = pos[0] + self.Size/2.0 y1 = pos[1] + self.Size/2.0 self.SystemCanvas.coords(ID, x0,y0,x1,y1) def UpdatePosition(self, angle, center, distance): """Calculate next object position around the Center at the Distance and speed determine by Angle (in Radian) - Center of the object""" h = center[0] k = center[1] radius = distance Rad = angle x = h+radius*math.cos(Rad) y = k+radius*math.sin(Rad) return (x, y) def UpdateCanvasSize(self, event): """Permit to resize the canvas to the window""" self.SizeX, self.SizeY = self.master.winfo_width(), self.master.winfo_height() self.SystemCanvas.config(width=int(self.SizeX*0.75)-20, height=self.SizeY-20) def move_start(self, event): """Detect the beginning of the move""" self.SystemCanvas.scan_mark(event.x, event.y) self.SystemCanvas.focus_set() #security, set the focus on the Canvas def move_move(self, event): """Detect the move of the mouse""" self.SystemCanvas.scan_dragto(event.x, event.y, gain=1) def zoomer(self,event): """Detect the zoom action by the mouse.
