Python + Tkinter Windows 7 任务栏进度 [英] Python + Tkinter Windows 7 taskbar progress

问题描述

我想在任务栏按钮中显示我的应用程序的进度.我使用这个答案作为参考.

I want to show the progress of my app in a taskbar button. I used this answer as a reference.

这是我所做的一个例子:

Here's an example of what I do:

import tkinter

import comtypes.client as cc
cc.GetModule("TaskbarLib.tlb")

import comtypes.gen.TaskbarLib as tbl
taskbar = cc.CreateObject(
    "{56FDF344-FD6D-11d0-958A-006097C9A090}",
    interface=tbl.ITaskbarList3)

class gui(object):
    def __init__(self, root):
        self.root = root

if __name__ == "__main__":
    root = tkinter.Tk()
    app = gui(root)

    taskbar.HrInit()
    taskbar.SetProgressValue(root.winfo_id(),40,100)

    root.mainloop()

但我在任务栏按钮上看不到任何进展.我做错了什么?

But I see no progress on a taskbar button. What do I do wrong?

推荐答案

需要激活选项卡.在taskbar.HrInit()之后添加taskbar.ActivateTab(root.winfo_id()).在 tkinter 中最好使用 int(root.wm_frame(), 16) 而不是 root.winfo_id() 因为否则在 tkinter 选项卡附近会出现一个带有进度条的 python 选项卡.最后应该调用 taskbar.SetProgressState(HWND, TBPF_NOPROGRESS) 来移除进度条.

The tab needs to be activated. Add taskbar.ActivateTab(root.winfo_id()) after taskbar.HrInit(). In tkinter is better to use int(root.wm_frame(), 16) instead root.winfo_id() because otherwise near tkinter tab will appear a python tab with a progressbar. At the end taskbar.SetProgressState(HWND, TBPF_NOPROGRESS) should be called to remove the progressbar.

需要定义标志.例如.TBPF_NOPROGRESS = 0.查看 Microsoft 网页以获取更多选项:https://msdn.microsoft.com/en-us/library/windows/desktop/dd391697%28v=vs.85%29.aspx

The flags need to be defined. Eg. TBPF_NOPROGRESS = 0. Check Microsoft's webpage for more options: https://msdn.microsoft.com/en-us/library/windows/desktop/dd391697%28v=vs.85%29.aspx

我知道这是一个老问题，但也许有人会觉得它有用.

I know this is an old question but maybe someone will find it useful.
