自定义功能区控件.可能吗? [英] customizing ribbon bar controls. is it possible?

问题描述

我正在使用vs2010，并且有一个带功能区栏的MFC应用程序

我正在使用CMFCRibbonSlider，但我认为这是任何功能区控件的普遍问题

我想更改滑块的外观.我将其用作音量控制幻灯片，希望滑块部分看起来像拉长的三角形(例如vlc的音量控件)，而缩放按钮看起来像小扬声器和大扬声器.

通常我会从CMFCRibbonSlider派生一个类，并覆盖OnDrawRibbonSliderZoomButton例如，但是我的应用程序中的所有控件都是这样创建的

i''m using vs2010 and have an MFC app with a ribbon bar

i''m using CMFCRibbonSlider but i think this is a general question for any ribbon control

i would like to change the look of the slider. i''m using it as a volume control slide and want the slider part to look like a stretched out triangle (like vlc''s volume control) and the zoom buttons to look like small speaker and big speaker

normally i would make a derived class from CMFCRibbonSlider and override OnDrawRibbonSliderZoomButton for example but all the controls in my app are created like this

m_wndRibbonBar.Create(this);
m_wndRibbonBar.LoadFromResource(IDR_RIBBON);

从资源中获取资源，因此我无法想到改变控件的任何行为.

您是否认为有办法以某种方式将自己的海关控制添加到功能区，并且仍然使用功能区设计器与以编程方式创建功能区?

例如，假设我完成了装箱工作，但创建后以某种方式覆盖CMFCRibbonSlider :: OnDraw(CDC * pDC)并将其指向我自己的CMFCRibbonSlider :: OnDraw(CDC * pDC)版本，在这里我可以做我想做的任何事情.

这是合法的C ++编程吗?如何在运行时重写类?

P.S.我尝试简单地编写自己的On Draw函数

from the resources so i have no way that i can think of to change any of the behavior of the control.

do you think there is a way to somehow add your own customs controls to the ribbon and still use the ribbon designer vs. creating the ribbon programmatically?

for example, suppose i get the crate do its job but after creating i somehow override CMFCRibbonSlider::OnDraw(CDC* pDC) and point it to my own version of CMFCRibbonSlider::OnDraw(CDC* pDC)where i can do whatever i want.

it this legitimate c++ programming? how would one override a class at runtime?

P.S. i tried simply writing my own On Draw function

void CMFCRibbonSlider::OnDraw(CDC* pDC)
{
    TRACE("this is my CMFCRibbonSlider::OnDraw\n");
}

(奇怪地)编译但没有被调用

[edit:已移出表格的答案]
问题是:如何使功能区设计师认识新的职业?

which compiles (strangely) but does not get called

[edit: moved form answer]
The question is: How to get the ribbon designer to recognize the new class?

推荐答案

您需要创建一个从CMFCRibbonSlider派生的自己的类，并覆盖要处理的功能.

You need to create your own class derived from the CMFCRibbonSlider and override the functions that you want to handle.

我遇到了完全相同的问题，并通过在MSDN论坛上提问获得了答案.像您一样，我无法弄清楚如何使用A派生功能区控件类，尤其是在使用功能区设计器时，因为功能区控件是在MFC中实例化的.一旦向我指出该解决方案就很容易:创建功能区后，枚举子窗口以查找上下控件，然后将其子类化并拦截UDN_DELTAPOS.您可以通过在MSDN论坛上搜索我的论坛名称johnsssl来查看完整的答案.哦，在获得上下控件的窗口之后，您将获得其父窗口并为父类子类化，因为控件通知将转到父类.

I had the exact same problem and got the answer by asking on an MSDN forum. Like you, I could not figure out how use a to derived a ribbon control class, especially when using the ribbon designer, since the ribbon controls are instantiated deep within MFC. The solution was easy once pointed out to me: After the ribbon has been created, enumerate the child windows to find the up-down control(s), then subclass them and intercept the UDN_DELTAPOS. You can see the full answer by searching on the MSDN forums for my forum name, johnsssl. Oh, after getting the up-down control''s window, you get its parent window, and subclass the parent, since the control notifications go to the parent.
