Python中使用tkinter创建透明图层、不规则组件、插入GIF动图等功能实现
心心念念的几个功能终于实现了，之前在StackOverflow上找了很久都没有人能实现，今天构思了一下，
果然是透明图层、不规则组件、插入GIF动图这一系列问题就是要把握好刷新的时机才能实现的
先来看一下效果：
几个主要函数：
1，自动刷新函数：
》》》注意：不规则的画布绘图，以及动态GIF图一定要写在此层函数内，不然无法刷新显示！！《《《
def refresh(): canvas.create_rectangle(0, 0, canvas.winfo_width(), canvas.winfo_height(), fill=TRANSCOLOUR, outline=TRANSCOLOUR) canvas.create_polygon((80,150),(370,150),(430,365),(25,365) ,fill = '#FF4081', width = 0,tags=('LabelRect')) canvas.tag_bind('LabelRect',"<Button-1>",Cavas_Click) canvas.tag_bind('LabelRect',"<ButtonRelease-1>",Cavas_Release) canvas.tag_bind('LabelRect',"<B1-Motion>",OnMotion) canvas.create_image(200,100,image=fi,anchor="nw") update(1) tk.after(100, refresh)
2，鼠标拖动事件：
def Cavas_Click(event): global x, y x = event.x y = event.y print('开始移动') def Cavas_Release(event): x = None y = None def OnMotion(event) : global x, y deltax = event.x - x deltay = event.y - y _x = tk.winfo_x() + deltax _y = tk.winfo_y() + deltay tk.geometry( "+%s+%s" % (_x, _y))
3，动态图片自动更新帧数函数：
def update(flags): global ind ## print(ind) if flags: try: canvas.delete('imageC') if (ind == framenum-1):# ind = 0 frame = frames[ind] image1 = canvas.create_image((80,220),image=frame,anchor='w',tags='imageC') ind += 1 except: pass
4，主函数区：
if __name__ == '__main__': fip="eng.png"#你的透明背景图片位置 TRANSCOLOUR = 'gray' tk = Tk() fi=PhotoImage(file=fip) tk.geometry('500x400+500+150') tk.title('透明窗体') tk.overrideredirect( True) ## tk.wm_attributes("-topmost", True) #窗口置顶 ## tk.wm_attributes("-disabled", True) #窗口禁动 tk.wm_attributes('-transparentcolor', TRANSCOLOUR) tk['bg'] = TRANSCOLOUR canvas = Canvas(tk,highlightthickness=0) canvas.pack(fill=BOTH, expand=Y) L1 = Frame(canvas) B1 = Button(L1,text='点击登录') B1.place(relx=0,rely=0,relwidth=1,relheight=1) W1 = canvas.create_window((100,300),window=L1,anchor='w',width=120,height=30) tk.after(0, refresh) #自动刷新 framenum = 8 # gif 的帧数需要确定下来 giffile = 'head3.gif' #找一张白色背景的gif，设置白色为透明 frames = [PhotoImage(file=giffile,format = 'gif -index %s' % i) for i in range(framenum)] tk.mainloop()
5，代码全部合并起来：
from tkinter import * x,y = 0,0 ind=1 def refresh(): canvas.create_rectangle(0, 0, canvas.winfo_width(), canvas.winfo_height(), fill=TRANSCOLOUR, outline=TRANSCOLOUR) canvas.create_polygon((80,150),(370,150),(430,365),(25,365) ,fill = '#FF4081', width = 0,tags=('LabelRect')) canvas.tag_bind('LabelRect',"<Button-1>",Cavas_Click) canvas.tag_bind('LabelRect',"<ButtonRelease-1>",Cavas_Release) canvas.tag_bind('LabelRect',"<B1-Motion>",OnMotion) canvas.create_image(200,100,image=fi,anchor="nw") update(1) tk.after(100, refresh) def Cavas_Click(event): global x, y x = event.x y = event.y print('开始移动') def Cavas_Release(event): x = None y = None def OnMotion(event) : global x, y deltax = event.x - x deltay = event.y - y _x = tk.winfo_x() + deltax _y = tk.winfo_y() + deltay tk.geometry( "+%s+%s" % (_x, _y)) def update(flags): global ind ## print(ind) if flags: try: canvas.delete('imageC') if (ind == framenum-1):# ind = 0 frame = frames[ind] image1 = canvas.create_image((80,220),image=frame,anchor='w',tags='imageC') ind += 1 except: pass if __name__ == '__main__': fip="eng.png"#你的透明背景图片位置 TRANSCOLOUR = 'gray' tk = Tk() fi=PhotoImage(file=fip) tk.geometry('500x400+500+150') tk.title('透明窗体') tk.overrideredirect( True) ## tk.wm_attributes("-topmost", True) #窗口置顶 ## tk.wm_attributes("-disabled", True) #窗口禁动 tk.wm_attributes('-transparentcolor', TRANSCOLOUR) tk['bg'] = TRANSCOLOUR canvas = Canvas(tk,highlightthickness=0) canvas.pack(fill=BOTH, expand=Y) L1 = Frame(canvas) B1 = Button(L1,text='点击登录') B1.place(relx=0,rely=0,relwidth=1,relheight=1) W1 = canvas.create_window((100,300),window=L1,anchor='w',width=120,height=30) tk.after(0, refresh) #自动刷新 framenum = 8 # gif 的帧数需要确定下来 giffile = 'head3.gif' #找一张白色背景的gif，设置白色为透明 frames = [PhotoImage(file=giffile,format = 'gif -index %s' % i) for i in range(framenum)] tk.mainloop()
大功告成！！如果需要更复杂的功能请自行DIY，原理是一样的。
