Quick Tour Of New MFC Functionality

Quick Tour Of New MFC Functionality

Hi I’m Pat Brenner, a developer on the Visual C++ libraries team.  I’m pleased to give you a sneak peek at a major MFC update we’ve been working on.  Since we’re adding a number of cool new user interface components to MFC, this blog post is going to be graphics heavy.  I’d much rather show you some of these components than just describe them!  I hope you enjoy this quick tour through the new portions of the library.


Modern user interface elements


This update to the MFC library will enable developers to build modern user interfaces with support for the Office 2007 Ribbon Bar, Office-style menus, Visual Studio-style docking toolbars, tabbed documents and much more.   All of the components included in the update will run on Windows 2000 and above.


Let’s take a look at some of the Office 2007 Ribbon Bar support.  Below is an image of an MFC application built with the Office look and feel:


 Ribbon Application

The ribbon support includes support for the application button (the large round button at the top left), the quick access toolbar (the small set of tools just to the right of the application button) and the standard ribbon components.  Each tab on the ribbon (e.g., the “Home” tab above) allows access to a category of tools.  Each category is divided up into a set of panels (e.g., “Clipboard” and “Font” above) and each panel contains a set of ribbon elements.  These ribbon elements can have a wide variety of styles—I’ll go into more detail about these later.


Perhaps many of you would like to build applications that utilize some of the functionality we’ve had in Visual Studio.  For example, one of the most requested features is support for the smart docking we added in Visual Studio 2005.  With this new release, all the cool user interface features you’ve seen in the past versions of Visual Studio are at your disposal.


Let’s take a look at some of the Visual Studio support.  Below is an image of an MFC application built with the Visual Studio look and feel:

VS2005 Docking (edit)


MFC now implements its own menu bar and toolbar, which is fully customizable like the Visual Studio toolbar and menu bar.  This means that buttons can be moved between toolbars, and even from the toolbar to the menu bar and vice versa.   Custom toolbars can be created, and commands can be added to them.  And the images for the individual toolbar buttons can even be changed, and custom images can be created and used.  Support for docking panes is also included—these panes can be grouped into one docking frame as above, they can be floating as well as docked, and they support auto-hide mode like in Visual Studio, so a docked pane will slide out from the edge of the frame when its tab is hovered over, mimicking the Visual Studio behavior.  There is also support for tabbed MDI documents (which can be grouped) like in Visual Studio.


Ribbon Elements


In addition to all the features supporting Office, Internet Explorer and Visual Studio “look and feel” there are a number of built-in cool elements you can use in the ribbon in your application.  In the images below, we provide a quick visual introduction to what’s included in the library.  The images come from the RibbonGadgets example that ships with the library.


In the image below you can see large and small buttons, as well as check boxes.  The buttons can be simple (so they just respond to a click), or they can drop down a menu or be a split button which responds to the click or drops a menu depending on the click location.

RibbonGadgets 1 (edit) 

In the image below you can see what we call palette buttons.  These can be a set of buttons that have associated images, so the user can see what he will get when he clicks on a button in the palette.  These palettes can be embedded in the ribbon, or they can be dropped down from a button in a window which can be resized dynamically by the user.

 RibbonGadgets 2 (edit)

In the image below you can see a variety of color choosers.  These can be embedded in the ribbon, or they can be attached to a button.  The table of colors associated with the chooser can be customized in your application.  There is a color picker dialog which offers even more flexibility, including the ability to choose the color of any pixel on the screen and use that color.

RibbonGadgets 3 (edit)

In the image below you can see groups of commands.  A ribbon group can be built from an existing toolbar, so if your application has a large number of toolbars, you can place them on the ribbon with ease.


RibbonGadgets 4 (edit)                         

In the image below you can see support for edit boxes, combo boxes and spin controls, as well as the font picker control, which can display the font names in the font (as in Word) so you get an instant preview of the font appearance.

RibbonGadgets 5 (edit) 

Below you can see a few more ribbon elements.  Several of these, including the progress indicators and the links and sliders, actually make more sense on the ribbon status bar, which you can see in the first image at the top of this article.


RibbonGadgets 6 (edit)                                                         

Powerful application wizard


We’ve also beefed up the MFC Application Wizard (see the images below) quite a bit to enable easy use of these new features in MFC.  We’ve added a couple of options to the “Project Style” category which will allow you to build a project that looks something like Visual Studio or an Office application by default.  We’ve added the option to use tabbed MDI document windows rather than the old MDI style.  And we’ve added the ability to choose the look and feel of your application with the “Visual Style and Colors” combo box.


An option that is hidden in this image is a checkbox that allows your application look and color to be changed at runtime.  You can choose your application look and color at design time, but if the user wants to change it, he can do so easily.  This is possible because the drawing of all the user interface elements is done via what is called a “visual manager”.  The visual manager takes care of all the drawing of elements, so if a different look is desired, all that is required is to switch to a different visual manager, and redraw the window, and your application instantly has a completely new look.  As you can see in the image below,  a number of schemes are supported, including Office 2003, Visual Studio 2005, and several different Office 2007 schemes which use different colors.  All of these are implemented using visual managers.



An option that is disabled in the image below (because ribbon was chosen instead of menu bar) is a checkbox that enabled “personalized menu behavior”.  This means that the menus will not show all commands by default, just like in Office applications.  When a menu is hovered over briefly, the menu will expand to contain its full set of commands.  And as the application is used, the most-used commands are added to the menu by default, so over time, the menu will become personalized to how it is being used.




Below is a screenshot of a running application which uses a ribbon.  This is actually the application created by the Application Wizard when the “Office” project style is chosen.  There is an Outlook-style navigation bar docked on the left side of the frame, and a caption (or message) bar at the top of the client area.  Note that the application button, quick access toolbar buttons, and the ribbon elements have keyboard hotkeys which are available when the Alt key is pressed.  On the right hand side of the ribbon is a drop-down element named “Style”, and from it you can choose which color you’d like the application to be presented in.

Easy to update existing MFC code


One of the great things about the new components is that they’re easy to incorporate into existing applications.  All of the new behavior is encapsulated in new classes, and none of the existing classes have been modified.  If you want to update your existing MFC application to use the new menu bar and toolbar support, all that is required to update your application to the new look is to change the base classes of your application and frame windows, and add a few lines of code, and you’ve just updated your application to have a more modern interface. 


Below is an image of the new DrawClient sample.  This is a remodel of the DrawCli sample that ships with MFC—it’s been updated to include Ribbon support.  Most of the modifications to the source code were in mainfrm.h and mainfrm.cpp.  The ribbon is currently built entirely in code.  The ribbon is created and then the various ribbon elements (application button, quick access toolbar, categories, etc.) are added via calls to ribbon member functions.  However, the underlying command architecture did not have to change—all the ribbon controls can be associated with a command identifier, and when the command is fired, it is handled via the existing command handlers.  The object drawing code did not have to change in any substantial way—it was only augmented to allow a few new capabilities.  One of these capabilities is something I’ll call “command preview”.  This means that, just like in the new Office applications, you can see the effect of a command before actually choosing it.  For example, the purple rounded rectangle is active below.  As you float the mouse over the large color buttons in the ribbon, the rectangle will temporarily change color to match the color of the button the mouse is hovered over.  When you click on the button, the color of the rectangle will then be changed.

We’re pretty excited about all these new additions to MFC, and we hope you are too!  Feel free to ask any questions you have about the new features and I’ll do my best to answer.

Visual C++ Libraries Development 

  • People still use MFC?  Yikes!  I suppose legacy apps won't let you get away from it.  

    Maybe it's time that you think about plain Win32 apps.

  • I love this news!! Excellent stuff!!

  • Hello I just download a tial version of VS2008 and can't see these dialog.

  • Will the new Office-style ribbon bar integrate correctly with an embedded Excel 2007 view?  In the current MFC, this is a problem for me.  When I bring up the Excel 2007 view, I get Excel's ribbon bar which *will not go away* when I switch to other views.  Nor do I get any sort of "combined" menu as I would have with Excel 2005 and earlier.

    Since I *really* need a way to embed Excel in my application, this isn't helping...


  • Please do not increase the size of MFC DLL's - no matter how cool the components may be.  Most people are not writing Visual Studio IDE clones anyway so why pay the penalty.  Please make it a separate DLL.

    Also, please make it easier to deploy shared VC dlls without using MSI files or vcredist.  I want to put the standard C++ runtime library in a shared folder.  I don't want MSI files or bloated vcredist.exe that creates a separate entry in Add/Remove programs.

  • Hello,

    I am a small ISV, and I like the initiative of integration between ATL and MFC and I also would like to see more shared libraries initiatives.

    One size fits all....  why not...

    I can do GUI apps, servers app, simple console tools, using utilities classes...

    But integrating external code into MFC in the central MFXxx.dll is strange. Original VC++ guys would not have approved this kind of decisions.

    Lightweight libraries is the finest choice but it seems now library size do not matter anymore.

    MFC library (also ATL) are the latest MS library shipped who can make professional apps with high requirements inside. If thirty party code are integrated into, why not to have choosen external library loading using interfaces (virtual classes) as a MFC Extension Library ?

    Hey guys, this is the coolest way to integrated extensions into MFC.

    Do you remeber RogueWave MFC extensions library. It was included with source code, speed execution, quality and MFC requirement.

    It was shipped as an external library.

    We should have the choice:

    - static MFC and static MFCGUI

    - shared libraries

    and the posssibility to load others visual and GUI thirty library. It is not so complicated to design.

    Every classes depends on CWnd and CCmdTarget stuff so why not to have choosen the real spirit of the MFC to ship another version of the MFC library.

    Integrating BCG like that is somewhat to be time to market...

    I will download via MSDN subscriptions and I will try.

    Christophe Pichaud,


  • All looks very pretty ... but a few questions:-

    1) Will it compile previous MFC code without errors (I'm not referring to the depreciated stuff which generated disable-able warnings).

    2) What behind the scenes classes are there ? Decent XML support for example ? Classes that simplify connectivity ?

    3) Please please *please* pretty-please-with-bells-on bring back class wizard! Way easier to use.

    Moving to .NET means most MFC code I deal with will be legacy code or low level code so I'm afraid the extra eye-candy doesn't mean too much to me (other than perhaps tarting up an existing apps).



  • Okay, let me get this straight:  It looks like a couple dozen developers have chimed in on the "quality" issue over many dozens of posts.  And, if I may paraphrase, you're all belly-aching (or reverse belly-aching) about freaking pixels.  

    This is a code library!  Has _anyone_ checked to see if it leaks handles or memory?  Anyone run it through a good static code analysis engine to look for un-initialized data, double-deletes and the like?

    If you like getting paid to worry about pixels, halve your salary and go into graphic design.  Otherwise, stop hyper-focusing on your own ego and start thinking about how your library choices impact your customers.


    To the VC++ team:  Thank you for pushing MFC forward.  We may not love it, but we need it and appreciate the work that goes into it.

  • Lee, if you *aren't* concerned about pixels, flashing, control alignment, etc. You should keep your salary about the same and move to back end code :).

    We know must customers, management, etc couldn't give 2 sh*ts about flashing, flickering, 2hr installs, 60MB of mem usage, etc.

    But some of us take pride in our work :).

    I guess you don't care what kind of work the painter does on your house as long as he doesn't cause a leak in your roof :).

  • I can't believe this response to what is basically a gift.

    I was convinced (as were many others) that MFC was dead, and am I surprised and thrilled to see that Microsoft has any interest, what-so-ever, in keeping it alive in this .NET/managed world. I would guess that someone had to beg management to even allow them to update this library with MS's recent focus on .NET and C#.

    Keep in mind that MS didn't have to update MFC for Vista at all. We could have all had to go about our business writing apps in MFC that looked like they were circa 1995, or overriding the paint message and drawing our own unique UI's.

    Now, for no additional cost, they have included a library which will make our apps look like something from this generation. We don't have to buy a 3rd party library or write our own for a modern-looking app. I think that's great.

    As for the size of the DLL: get a grip. This additional 1-2MB is peanuts in today's world. I can transfer that on my internet connection to my house in what, 3 seconds? When was the last time you used a 1.44MB floppy disc to give someone an application you wrote? 1-2MB is nothing, these days, and who cares if you have to distribute it, even across a modem to a customer.

    I for one am ecstatic that the VC++ library team touched this code again... thank you! Grow up, crusty old coders. Yes, MFC is different than it was when it was invented, and that's a good thing. Hopefully we'll see many more years of support for MFC, native code, and C++.

  • Wow, the supported interface is looking more like a C64 app every day, more bright basic colors, bigger buttons, miniscule work space.  Why move backwards?  Making buttons bigger doesn't make the app more "user friendly."

  • I haven't written a circa 1995 looking app since, um... lets see... oh yeah... 1995! :). Microsoft stopped updating MFC after they added the rebar stuff. So, if you wanted modern UIs after that, you had to do it yourself. Only with Office 2003, did the Office UI start getting innovative.

    I think the size complaint is from people already using better 3rd party libraries (BCG is one of the worst). So Ok, chances are I'll still be able to use CJ if I want (after CJ irons out conflicts I'm sure). So I now need to ship TWO ribbon implementations in my apps??? Or have other conflicting problems?

    .Net doesn't really give you much UI for free either. Why should MFC? It helps seperate the men from the boys :).

    So the code is free... will you still like it after you need to spend 6 months fixing all the bugs that Microsoft won't?

  • BTW, have you even SEEN BCG code? I don't mean the lib itself, I mean the code YOU write... pretty much every control, sub item, GUI component is created like:

    Blah* pBlah = new Blah(param1, param2, param3);

    pBlah->Insert(new SubBlah);

    No wonder BCG performance sucks when they allocate memory for every pixel like that.

  • @Frank L: The color schemes are customizable.

    @Lee: I'm not sure what platforms you or your company targets, but the BCG library have not degraded performance for us any more than e.g. a typical Office UI would.

  • This is great ... I also agree with the one poster that codejock is better ..
