Isa*_*Isa 2 tkinter python-2.7 progress-bar
我Progressbar在tkinter(python 2.7)中理解小部件时遇到了一些麻烦我去了这里和这里,但我仍然不明白如何将Progressbar自身(在"确定"模式下)链接到我的函数.
有没有人有关于如何将功能完成链接到进度条更新的任何示例?请不要因缺乏研究而投票; 我对此做了研究,我找不到任何有用的信息.关于我(已经工作的)代码的注释 - 在运行代码时创建.txt文件,该文件打印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.
编辑:更具体地说,如何将值更改为正确的数字?
工作示例 - 您可以在两种类型的进度条中查看当前值和最大值.
-
您可以使用self.var_ind.set()或self.var_det.set()在您的函数(内部类MainWindow)中更新进度条.
-
如果你的函数在class之外,你必须用它self.var_ind或self.var_det作为参数调用它.
your_function(self.var_det)

和内部功能使用它
def your_function(progress):
progress.set(10) # set new value
progress.set( progress.get() + 23 ) # add 23 to current value

我使用var_ind.set()和self.var_det.set()在BEGIN,SET 23,END树立新的价值.
-
如果您必须max在进度条中设置,则还需要添加self.pbar_ind或self.pbar_det作为参数.
your_function(self.var_det, self.pbar_det)

和内部功能使用它
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

(为了创建示例,我使用了 Gianni Spear问题中的部分代码在tkinter中使用相同的进度条进行Python中的多次计算)
