位图按钮功能 [英] Bitmapped button functionality

问题描述

你好，

我有一个与启用了位图的对话"窗口的使用有关的问题.我已经创建了一个键盘类型布局，并且我也希望通过键盘获得输入.使用鼠标时，我可以按下按钮，并且所有按钮都可以正常工作-其他图像DEFAULT，SELECTED，DISABLED ...都已加载并可以正常工作，因为我正在使用功能.但是，然后，按下键盘上的任何键以及屏幕上相应的字符都无法完成我通过单击鼠标(并使用Loadbitmaps() 功能)所能完成的操作.

我正在使用这三个功能来实现与使用鼠标相同的作用和效果:

-LoadBitmap()
-SetBitmap()
-Invalidate()

但是，尽管它们在内部起作用，但似乎并没有给按钮带来效果.有人可以帮我吗?

谢谢和问候

Hello there,

I have an issue related to the usage of the bitmap enabled Dialog window. I have created a keyboard type layout and I wish to get the input through keyboard also. When I use the mouse, I am able to get the button(s) pressed and also all the buttons are working fine - the other images DEFAULT, SELECTED, DISABLED... all get loaded and work since I am using the function m_BtnBtn1Ctrl.LoadBitmaps. But then, any key pressed on keyboard and the corresponding character on the screen isn''t able to do the same as I have been able to do it with clicking of the mouse (and using the Loadbitmaps() function).

I am using these 3 functions to achieve the same action and effect as that of using a mouse:

- LoadBitmap()
- SetBitmap()
- Invalidate()

But these don''t seem to give the pressed button effect though internally they work. Can some one please help me with this?

Thanks and regards
Sayonee

    CString strTemp;
    if (pMsg->message == WM_KEYDOWN)
    {
        if ( pMsg->wParam == 0x41 || pMsg->wParam == 0x61) //check for both 'a' and 'A'
            OnBtnBtn1();
        if (pMsg->wParam == VK_RETURN || pMsg->wParam == VK_DELETE ||
            pMsg->wParam == VK_ESCAPE || pMsg->wParam == VK_TAB ||
            pMsg->wParam == VK_UP || pMsg->wParam == VK_DOWN || GetKeyState (VK_CONTROL))
            {
                ::TranslateMessage (pMsg);
                ::DispatchMessage (pMsg);
                return TRUE;                // DO NOT process further
            }
    }
    return CDialog::PreTranslateMessage(pMsg);
}

我想这与焦点有关吗?尝试SetFocus().

I guess it has something to do with focus? Try SetFocus().
