tkinter库Canvas操作三个实例

实例一：涂鸦

import tkinter as tk import pyautogui as ag from time import sleep def paint(event):         x1, y1 = (event.x - 1), (event.y - 1)         x2, y2 = (event.x + 1), (event.y + 1)         tCanvas.create_oval(x1, y1, x2, y2, fill = "black") def moveRect(w,h):         ag.moveRel(w,0, duration=w/1000)  # moveRel移动  # dragRel拖曳         ag.moveRel(0,h, duration=h/1000)         ag.moveRel(-w,0, duration=w/1000)         ag.moveRel(0,-h, duration=h/1000)         sleep(0.5) win = tk.Tk() X,Y=ag.size() winPos = "640x480+" winPos += str((X-640)//2)+"+" winPos += str((Y-480)//2) win.geometry(winPos) win.resizable(False, False) win.title('桌面分辨率：'+str(X)+"x"+str(Y)) win.update() tCanvas = tk.Canvas(win, width = win.winfo_width(), height = 400, bg = 'white') tCanvas.pack(side = "top")  tCanvas.bind("<B1-Motion>", paint) tCanvas.update() tk.Label(win, text = "画布作图").pack(side = "bottom") x0,y0 = 150,60 w,h = 350,160 x , y = win.winfo_rootx()+x0, win.winfo_rooty()+y0 ag.moveTo(x, y, duration=0.5)  moveRect(w,h) #画直线 tCanvas.create_line(x0, y0, x0+w, y0) tCanvas.create_line(x0+w, y0, x0+w, y0+h) #可以把左上和右下两个坐标点一起赋值给变量 coord = x0+w, y0+h, x0, y0+h tCanvas.create_line(coord) coord = x0, y0+h, x0, y0 tCanvas.create_line(coord, fill = 'blue') tCanvas.update() moveRect(w-h/3,h) #画矩形 coord = x0+1,y0+1,x0+w-1-h/3,y0+h-1 tCanvas.create_rectangle(coord,fill='limegreen') tCanvas.update()  moveRect(h,h) #画圆或椭圆 coord = x0,y0,x0+h,y0+h tCanvas.create_oval(coord,fill='deepskyblue') tCanvas.update() x0=x0+h/2 ag.moveRel(h/2,0) moveRect(w-h/2,h) coord = x0,y0,x0+w-h/2,y0+h tCanvas.create_oval(coord,fill='deeppink') tCanvas.update()  #画扇形、弓形或一段弧 #type = PIESLICE 扇形、CHORD 弓形、ARC 弧形 sleep(1) coord = 100, 100, 300, 300 tCanvas.create_arc(coord,start=0,extent=180,fill='gold') tCanvas.update() sleep(1) coord = 240, 60, 490, 310 #颜色也可用6位16进制数的GRB值表示 tCanvas.create_arc(coord,style=tk.CHORD,start=10,fill='#7CFC00') tCanvas.update() sleep(1) coord = 180, 10, 470, 300 tCanvas.create_arc(coord,style=tk.ARC,width=3,dash=6,extent=-180) #参数有很多，可以上网搜相关参数表  win.mainloop()

运行效果图：

注：程序运行时，按下鼠标左键就可以在画布上作图，上图 python 字样就是本人所画 ^_^

其它作图函数：

# 多边形、三角形 tCanvas.create_polygon((10,100,10,180,100,180),fill='blue') # 文字 tCanvas.create_text((150,50),text=u'输出文字',anchor=E)  # 位图 bmap={1:'error',2:'info',3:'question',4:'hourglass'} for i in bmap:     tCanvas.create_bitmap((20*i,20),bitmap=bmap[i])  # 调入图片 img=PhotoImage(file='D:/pictures/exam.gif') tCanvas.create_image((200,200),image=img) tCanvas.pack()

实例二：颜色表

win.resizable(False, False) win.title('桌面分辨率：'+str(X)+"x"+str(Y)+' '*6+'窗口大小：'+str(W)+"x"+str(H)) win.update()  colorTuple=( ('black',                '#000000'), ('navy',                 '#000080'),

这些颜色已经足够多了，但据说装了seaborn扩展的话xkcd_rgb包含的颜色数(有英文名称的)会有更多......

实例三：围棋盘
