C ++的Win32单选按钮的背景颜色

问题描述

所以，首先，我使用Windows API，没有特殊的库。

So first i'm using the windows API, no special libraries.

我创建了一个单选按钮与此code：

I've created a radio button with this code:

g_hRadioButton = CreateWindowEx(0, "BUTTON", "Radio Button",
    WS_CHILD | WS_VISIBLE | BS_RADIOBUTTON,
    10, 55, 120, 25, hWnd, (HMENU)RADIOBUTTON, GetModuleHandle(NULL), NULL);

现在我有一个主窗口黑色背景，所以我想文字是白色，背景是透明的。

Now I have a black background for the main window, so I would like the text to be white, and the background to be transparent.

我已经试过检查均 WM_CTLCOLORBTN 和 WM_CTLCOLORSTATIC 消息。

I've tried checking both the WM_CTLCOLORBTN and WM_CTLCOLORSTATIC messages.

下面是我的code：

case WM_CTLCOLORBTN:
    SetTextColor((HDC)wParam, 0xffffff);
    SetBkMode((HDC)wParam, TRANSPARENT);
    return (LRESULT)GetStockObject(BLACK_BRUSH);

case WM_CTLCOLORSTATIC:
    SetTextColor((HDC)wParam, 0xffffff);
    SetBkMode((HDC)wParam, TRANSPARENT);
    return (LRESULT)GetStockObject(NULL_BRUSH);

这是不行的，背景仍然是白色，文本为黑色。

This doesn't work, the backgrounds still white and the text is black.

此外，我已经通过链接到ComCtl32.lib，创建清单并启用视觉样式了这一切。

Also i've enabled visual styles by linking to ComCtl32.lib, creating the manifest and all that.

编辑：

试图处理 NM_CUSTOMDRAW 消息现在来代替。
这里是我的code，但它有没有影响，我是pretty确保即时通讯做错了什么。

Trying to process the NM_CUSTOMDRAW message now instead.Here's my code but it's having no effect, and i'm pretty sure im doing something wrong.

case WM_NOTIFY:
{
    if (((LPNMHDR)lParam)->code == NM_CUSTOMDRAW)
    {
        LPNMCUSTOMDRAW nmCD = (LPNMCUSTOMDRAW)lParam;
        switch(nmCD->dwDrawStage)
        {
            case CDDS_PREPAINT:
                return CDRF_NOTIFYITEMDRAW;

            case CDDS_ITEMPREPAINT:
                SetTextColor(nmCD->hdc, 0xffffff);
                SetBkColor(nmCD->hdc, 0x000000);
                return CDRF_DODEFAULT;
        }
    }

    break;
}

有人能至少指向我朝着正确的方向？

Could someone at least point me in the right direction?

推荐答案

也许只要你的应用程序与视觉样式运行，你会好起来的处理的为按钮控制的通知。原来，这些人只有共同控制，但相当多的版本已经扩展按钮行为以同样的方式了。

Perhaps as soon as your application is running with visual styles, you will be better off handling NM_CUSTOMDRAW notification for button control. Originally, these were for common controls only, but quite a few versions are already extending button behavior the same way too.
