python - Python win32com 演示outlookaddin.py 控制按钮标题不起作用

问题描述

直截了当，我尝试使用 Python win32com 演示 OutlookAddin.py，它在 Outlook 2010 中运行良好。

我升级到 Outlook 2016，从那时起，outlookAddin.py 仍在工作，但是它在加载项功能区中添加的加载项 msoControlButton 没有标题。

谁能帮我理解如何解决这个问题。默认情况下，任何安装了 win32com 的人都可以使用该代码，但我仍然在下面给出它以供参考。

from win32com import universal
from win32com.server.exception import COMException
from win32com.client import gencache, DispatchWithEvents

# Support for COM objects we use.
gencache.EnsureModule('{00062FFF-0000-0000-C000-000000000046}', 0, 9, 0, bForDemand=True) # Outlook 9
gencache.EnsureModule('{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52}', 0, 2, 1, bForDemand=True) # Office 9

# The TLB defining the interfaces we implement
universal.RegisterInterfaces('{AC0714F2-3D04-11D1-AE7D-00A0C90F26F4}', 0, 1, 0, ["_IDTExtensibility2"])

class ButtonEvent:
    def OnClick(self, button, cancel):
        import win32ui # Possible, but not necessary, to use a Pythonwin GUI
        win32ui.MessageBox("Hello from Python")
        return cancel

class FolderEvent:
    def OnItemAdd(self, item):
        try:
            print("An item was added to the inbox with subject:", item.Subject)

            item.Enabled = True


        # And now, for the sake of demonstration, setup a hook for all new messages
        inbox = application.Session.GetDefaultFolder(constants.olFolderInbox)

解决方案

CommandBars已弃用。Office 2010 是第一个不将命令栏用于 UI 的版本。您可以在以下系列文章中阅读有关 Fluent UI（又名 Ribbon UI）的更多信息：

自定义 Office UI 的推荐方法是使用 Fluent UI。命令栏保持原位以实现向后兼容性，例如以编程方式执行按钮等。您现在不应该依赖命令栏来创建自定义 UI。
