python3.6 tkinter实现屏保小程序
本文实例为大家分享了python3.6 tkinter实现屏保小程序,供大家参考,具体内容如下
该小程序是在闲着没事的时候,随便写的,就当打发无聊了。
该程序是用python3.6写的,调用了python中的tkinter的库(*python2x与python3x的thinter有很多不同的地方,一定要特别注意!!!)
from random import randint from tkinter import * class Randball(): def __init__(self,canvas,scrnwidth,scrnheight): #初始化画布 self.canvas = canvas #初始化球的圆心坐标 self.x_pos = randint(50,int(scrnwidth))#X轴的坐标 randint 随机产生一个范围内的整数 self.y_pos = randint(50,int(scrnheight))#Y轴的坐标 #球的移动距离 self.x_move = 10 self.y_move = 10 #整个屏幕的高和宽 self.scrnwidth =scrnwidth self.scrnheight =scrnheight #初始化球的半径 self.randius = randint(10,80) #随机产生球的颜色 rc = lambda : randint(0,255) self.color = '#%02x%02x%02x'%(rc(),rc(),rc()) def create_ball(self): #计算得到用于创建球的四个坐标 x1 = self.x_pos - self.randius y1 = self.y_pos - self.randius x2 = self.x_pos + self.randius y2 = self.y_pos + self.randius #画球 self.item =self.canvas.create_oval(x1,y1,x2,y2,fill = self.color,outline = self.color) def move_ball(self): #球按照指定距离移动,如果碰到障碍就向相反的方向运动 self.x_pos += self.x_move self.y_pos += self.y_move if self.x_pos >= self.scrnwidth - self.randius: self.x_move = -self.x_move elif self.y_pos >= self.scrnheight - self.randius: self.y_move = -self.y_move elif self.x_pos < self.randius: self.x_move = abs(self.x_move) elif self.y_pos < self.randius: self.y_move = abs(self.y_move) self.canvas.move(self.item,self.x_move,self.y_move) class Screensaver(): balls = [] def __init__(self,ball_nums): self.win = Tk() self.width = self.win.winfo_screenwidth() self.height = self.win.winfo_screenheight() self.win.overrideredirect(True) self.win.attributes('-alpha',1) #绑定事件,有任何动作退出屏保 self.win.bind('<Any-Button>',self.exit_screensaver) self.win.bind('<Motion>',self.exit_screensaver ) self.canvas = Canvas(self.win,width = self.width,height = self.height,bg="#FFFFFF")#背景 颜色自己随便调整,至于啥颜色就看自己的心情了 self.canvas.pack() for i in range(0,ball_nums): ball = Randball(self.canvas,scrnwidth=self.width,scrnheight=self.height) ball.create_ball() self.balls.append(ball) self.run_screensaver() self.win.mainloop() def run_screensaver(self): for ball in self.balls: ball.move_ball() self.canvas.after(30,self.run_screensaver) def exit_screensaver(self,event): self.win.destroy() def main(): Screensaver(30)#屏保上球的个数 if __name__=='__main__': main()
