Re: Stop default handling of space bar in property sheet?

I would say, you should override the OnKeyDown() function instead.

Within that function, check the nChar parameter, and if it is the keyboard button, do your thing, then exit without calling the base class implementation. Or call the baseclass implementation, but change the value of nChar to somnething else that wouldn't be a problem for you.

Get back to us on that, please.

I wasn't able to get my OnKeyUp/Down functions working (in the sheet OR page), so I'm just catching the WM_KEYUP/DOWN in PreTranslateMsg in the sheet.

I finally got it working, by returning true (that function) if the key was pressed down, and by performing the action when the key was released. I thought I tried that before, but oh well Smile | :)

Thanks for the reply! Smile | :)

I am not using MFC stuff at all. How would overriding OnKeyDown() work? Thanks for the answer.

Thanks

Well, you check the parameter passed to this function, and if it's a "whatever you want" you don't call the base class implementation, isntead call whatever you need.
I thoguh it would be pretty obvious"? After all, it's the point (and power) of C++ operator overloading.

Toolbar Resizing

I have a toolbar and am adding text labels to the buttons. The problem is that the toolbar is not sizing itself properly and the toolbar is still the size of a regular toolbar. How do I tell the toolbar to size properly?

Are you sending TB_AUTOSIZE to cause resizing of the toolbar, or sending TB_SETBUTTONSIZE before adding buttons? Also, are you using Win32, MFC, or WTL, and do you mean sizing verically (text below images) or horizontally (next to images)?

I'm using MFC and I need to resize the toolbar vertically. I am trying to create Internet Explorer-like buttons. I didn't have a problem in Win32, but MFC doesn't resize the toolbar automatically.

So did you try sending the messages mentioned in my last post?

Try:

// change the toolbar size to accomodate the text<br />
	m_wndToolBar.SetSizes (TOOLBAR_BUTTON_SIZE, TOOLBAR_BUTTON_IMAGE_SIZE);

Thanks. One more question, how do I check toolbar buttons when using CToolBar instead of CToolBarCtrl? It doesn't have a CheckButton() function.

You can always get the underlying CToolbarCtrl and call its member functions.

Is there a way i can check the items without mixing classes?

Err..
Have you actually read the MSDN docs?
Get it, it's worth it, or go on the net to http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmfc98/html/_mfcnotes_tn031.asp

Anyway, you won't be mixing classes. Here's a quote from those documentations:

CToolBar::GetToolBarCtrl, a member function new to MFC 4.0, allows you to take advantage of the Windows common control's support for toolbar customization and additional functionality. CToolBar member functions give you most of the functionality of the Windows common controls; however, when you call GetToolBarCtrl, you can give your toolbars even more of the characteristics of Windows 95 toolbars. When you call GetToolBarCtrl, it will return a reference to a CToolBarCtrl object. See CToolBarCtrl for more information about designing toolbars using Windows common controls. For more general information about common controls, seeCommon Controls in the Windows 95 SDK Programmer’s Reference.

Hope that helps. Essentially, there's no harm, as CToolBar are made from (or using) the CToolBarCtrl.
I suggest you go to the docs... you'll learn a heck lot more.
