如何使MDI MFC应用程序在任务栏中显示一个实例? [英] How do you make your MDI MFC app show one instance in the TaskBar?

问题描述

我有一个MDI应用程序，当我单击新文档时，它会打开一个单独的选项卡.这将在Windows的任务栏中创建该图标的另一个实例.有什么办法可以改变这种行为，以便任务栏仅显示一个图标实例?

I have an MDI app and when I click new document, it opens up a separate tab. This creates another instance of the icon in the taskbar within Windows. Is there any way I can change this behavior so that only one icon instance is shown the taskbar?

我知道一种方法是使用SDI并在视图中使用选项卡，但我想将其保留为MDI.这有可能吗?

I know one way is to use SDI and use tabs for my views, but I want to keep it an MDI. Is this even possible.

我正在尝试模仿名为"Dameware NT Utilities"的特定应用程序的视图: http://www.dameware.com/v3-dameware/media/DameWare/DW%20NTU/Carousel/DRS-Primary-medium.png?width=490&height=276&ext=.png

I'm trying to mimic the view of this particular application called 'Dameware NT Utilities': http://www.dameware.com/v3-dameware/media/DameWare/DW%20NTU/Carousel/DRS-Primary-medium.png?width=490&height=276&ext=.png

推荐答案

经过一天的探索，我找到了解决方案.天哪，最终解决这个问题感觉很好.无论如何，这就是解决方案.

I found the solution after a day of digging around. Gosh, that feels good to finally figure this out. Anyway here is the solution.

我只需要重写子框架的CanShowOnTaskBarTabs()方法以返回FALSE.这是类方法:

I just had to override the childframe's CanShowOnTaskBarTabs() method to return FALSE. Here's the class method:

首先，在childframe.h文件中，将以下代码放入类声明中

first, in the childframe.h file, put the following code in the class declaration

public:
     virtual BOOL CanShowOnTaskBarTabs() override;

然后在childframe.cpp文件中，将以下代码放在最底部:

Then in your childframe.cpp file, put the following code at the very bottom:

BOOL CChildFrame::CanShowOnTaskBarTabs()
{
    return FALSE;
}
