我在理解 Progressbar 时遇到了一些麻烦tkinter (python 2.7) 中的小部件我去了 herehere但我还是不明白如何链接 Progressbar本身(在“确定”模式下)到我的功能。

有没有人有任何关于如何将功能完成与进度条更新联系起来的例子?我确实研究过这个,我只是找不到任何有用的信息。关于我的(已经可以工作的)代码的注释 - 在代码运行时创建了一个 .txt 文件,该文件打印了函数的总数和正在运行的当前函数。我想链接progressbar这些 .txt 文件中的信息。

更具体地说,如何将值更改为正确的数字?

最佳答案

工作示例 - 您可以在两种类型的进度条中看到当前值和最大值。

——

您可以使用 self.var_ind.set()self.var_det.set()在您的函数中(在类 MainWindow 内)更新进度条。

——

如果你的函数在类之外,你必须用 self.var_ind 调用它或 self.var_det作为论据。

 your_function(self.var_det)

和内部函数使用它
 def your_function(progress):
progress.set(10) # set new value
progress.set( progress.get() + 23 ) # add 23 to current value

我用 var_ind.set()self.var_det.set()BEGIN , SET 23 , END设置新值。

——

如果你必须设置 max在进度条中,您需要添加 self.pbar_indself.pbar_det也作为论据。
 your_function(self.var_det, self.pbar_det)

和内部函数使用它
 def your_function(progress, bar):

bar.config(maximum=200) # set max to 200

bar.step() # add 1 to current value
bar.step(23) # add 23 to current value

progress.set(10) # set new value
progress.set( progress.get() + 23 ) # add 23 to current value

编辑:带有更多按钮的新示例:
from Tkinter import *

class MainWindow(Frame):

def __init__(self):
Frame.__init__(self)
self.master.title("ProgressBar example")
#self.master.minsize(400, 100)
