问题描述
我正在使用 Tkinter 在我的项目中创建聊天，例如抽搐。是否可以在消息中使用动画（不仅是）表情符号制作聊天小部件？
代码：
def print_mess(self,mess):
self.console.configure(state='normal')
self.console.insert(END,mess.formated_time() + " ",'timesign')
self.console.tag_config('timesign',foreground='#C0C0C0')
self.console.insert(END,mess.username,mess.username)
self.console.tag_config(mess.username,foreground=mess.usercolor)
self.console.insert(END,": ",'mess')
self.console.insert(END,mess.message + "\n",'mess')
self.console.tag_config('mess',foreground='#FFFFFF')
self.console.yview(END) # autoscroll
self.console.configure(state='disabled')
解决方法
有多种方法，一种方法是使用标签并使用 <head>
<style>

示例：（拖放 gif。点击 gif 播放，修改它以满足您的需要）。
window_create()另一种方法是使用
import tkinter as tk
from PIL import Image,ImageTk
import windnd
class Text(tk.Text):
def __init__(self,*args,**kwargs):
super().__init__(*args,**kwargs)
self.gif = {}
self.index = 0
self.delay = 20
self.currentlyPlaying = None
self.currentId = None
def insert_gif(self,path):
gif = GifMaker(path)
label = tk.Label(image=gif.frames[0],bd=3)
label.bind('<1>',lambda event: self.playGif(label))
self.window_create("end",window=label)
self.gif[label] = gif
self.playGif(label)
def playGif(self,label):
if self.currentlyPlaying is None:
self.currentlyPlaying = label
if self.currentlyPlaying != label: # makes sure only one gif is played at any time
self.index = 0
self.currentlyPlaying.configure(image=self.gif[self.currentlyPlaying].frames[0])
self.currentlyPlaying = label
self.after_cancel(self.currentId)
self.index += 1
if self.index == self.gif[self.currentlyPlaying].n_frames-1:
self.index = 0
self.currentlyPlaying.configure(image=self.gif[self.currentlyPlaying].frames[self.index])
if self.index != 0:
self.currentId = self.after(self.delay,self.playGif,self.currentlyPlaying)
class GifMaker:
def __init__(self,path):
self.path = path
self.image = Image.open(path)
self.n_frames = self.image.n_frames # number of frames
self.frames = []
self.duration = 0 # total duration of the gif
for x in range(self.n_frames):
img = ImageTk.PhotoImage(self.image.copy())
self.duration += self.image.info['duration']
self.frames.append(img)
self.image.seek(x)
self.delay = self.duration//self.n_frames
def dropped(file):
text.insert_gif(file[0])
root = tk.Tk()
text = Text()
text.pack(fill='both',expand=True)
windnd.hook_dropfiles(root,func=dropped)
root.mainloop()
创建图像并使用 .image_create() 更新图像。 （推荐）
.image_configure()（通过添加类似上述方法的条件，确保在任何情况下只播放一个 gif）
输出：
