Question

我在将值更新到进度条时遇到问题，当我运行程序时，进度条卡在中间（只需单击下面的“在这里出现问题”按钮，它说明了我的意思），代码成功运行，而没有任何错误

这是我使用的代码：

self.bytes = 0
self.max_bytes = 0

self.progressbarframe = Frame(self.frameoutput, bg=self.bgcolor)
self.progressbarframe.place(relx=0.355,rely=0.78,relwidth=0.605)

self.progressbar = Progressbar(self.progressbarframe, orient=HORIZONTAL, mode='determinate')
self.progressbar.pack(fill=X)

def progress(curvalue, maxval):
    self.progressbar['value'] = curvalue
    self.progressbar['maximum'] = maxval

def cb(total, recvd, ratio, rate, eta):
    self.bytes += recvd
    self.max_bytes += total
    if self.bytes <= self.max_bytes:
        self.progressbar.after(50, progress(self.bytes, self.max_bytes))
        self.progressbar.update()

self.videos = pafy.new(str(self.entryyturl.get()))
self.videodownload = self.videos.allstreams
self.videodownload = self.videodownload[-int(self.data['mediatypes'].index(self.resolutionbox.get()))-1]
self.videodownload.download(quiet=True, filepath='download/{}.{}'.format(self.videodownload.title, self.videodownload.extension), callback=cb)

Problem Here

谢谢！

如何在tkinter中修复进度条的值（它仅在中间结束）
