Win32应用如何真正的重绘标题栏?

末影小末EnderMo 2020-07-22 04:12:49

我按照官方的docs代码如下

    case WM_NCPAINT:

    {

        HDC hdc;

        hdc = GetDCEx(hwndDlg, (HRGN)wParam, DCX_WINDOW | DCX_INTERSECTRGN);

        PAINTSTRUCT ps;

        RECT rect;

        HBRUSH hbr = CreateSolidBrush(RGB(0, 255, 255));

        hbr = (HBRUSH)SelectObject(hdc, hbr);

        //填充标题栏颜色

        Rectangle(hdc, 0, 0, 40, 200);

        ReleaseDC(hwndDlg, hdc);

}

想[真正意义上]重新绘制标题栏,而不是把标题栏去掉在WM_PAINT里绘制客户区
理论是用WM_NCPAINT消息吧
但加入代码后,绘图代码未生效,而且WIN10还离奇出现类似于Win7的标题框样式,如图

请问怎么解决这个问题呢?

没有·自己改改‘



void CMyFileOpenDlg::GradientCaption(CDC* pDC, CRect rRect, COLORREF crFrom, COLORREF crTo )

{

	int iHeight = rRect.Height();

	int iWidth	= rRect.Width();

//

	int iR	= GetRValue( crFrom );

	int iG	= GetGValue( crFrom );

	int iB	= GetBValue( crFrom );

//

	int idR = (256*(GetRValue(crTo)-iR)) / iWidth;

	int idG = (256*(GetGValue(crTo)-iG)) / iWidth;

	int idB = (256*(GetBValue(crTo)-iB)) / iWidth;



	iR *= 256;

	iG *= 256;

	iB *= 256;

// ->

	for ( int i = rRect.left; i <= iWidth; i++, iR += idR, iG += idG, iB += idB )

	{

		pDC->FillSolidRect(i, rRect.top, 1 , iHeight, RGB( iR / 256, iG / 256, iB / 256 ) );

	}

}

void CMyFileOpenDlg::OnNcPaint() =case WM_NCPAINT
BOOL CMyFileOpenDlg::OnNcActivate(BOOL bActive) =case WM_NCACTIVE
void CMyFileOpenDlg::DrawCaption()=void DrawCaption()
CDC* pWinDC改 HDC hdc
。。。
取消所有类

其中哪些需要改成case WM_XXX呢?
