在MFC中更新工具栏按钮状态 [英] Updating toolbar button state in MFC

问题描述

我在MFC应用程序中有一个对话框，它有菜单栏。现在，我使用菜单栏中的相同命令在该对话框中创建了一个工具栏。

I have a dialog in MFC application, which was having menu-bar. Now I have created a toolbar in that dialog using the same command which was in the menu-bar.

我用来更新菜单项的状态，并按照某些检查启用/禁用，当我点击菜单时。但是对于工具栏，我没有得到这些调用来更新它的状态，如果应该启用/禁用它。

I use to update the menu-item's state and makes it enable/disable as per some check, When I clicks on the menu. But for toolbar I didn't gets these calls to update it's state, If it should be enabled/disabled.

此外，当测试失败时我没有任何通知，而且我要禁用该项目。

Moreover I didn't have any notification when the test fails and I to disable the item.

是否有替代方案这样做？

Is there some alternative for doing this?

谢谢

推荐答案

在基于对话框的应用程序中未提供使文档/视图应用程序中的ON_UPDATE_COMMAND_UI工作的MFC代码。你可以自己添加它，如本文所示：

The MFC code that makes ON_UPDATE_COMMAND_UI work in a doc/view app is not provided in a dialog based app. You can add it yourself as shown in this article:
