如何设计FRAMEWND OR WND 的背景色

[diva]

在VC6中无SETBACKCOLOR ，SETCLIENTBACKCOLOR，请问可用何法。谢谢

其实你开始按照zdg的做法，在OnSize后颜色又掉了，是因为你没有将原来的return....句换成return TRUE;

重载OnEraseBkgnd函数...

我用过ONERASEBKGND，但ONSIZE后，背景色又没了，所以我想SETBKCOLOR，可以不再管它了。请问还有何法？

在CSDN网站或程序员大本营光盘中的VC源程序中包含一篇
CFormView Class with Custom Background Color

相信对你有用...

如何改变视窗的背景颜色???

Windows向窗口发送一个WM_ERASEBKGND消息通知该窗口擦除背景，可以使用ClassWizard重载该消息的缺省处理程序来擦除背景（实际是画），并返回TRUE以防止Windows擦除窗口。

//Paint area that needs to be erased.

BOOL CSampleView : : OnEraseBkgnd (CDC* pDC)

{

// Create a pruple brush.

CBrush Brush (RGB (128 , 0 , 128) );

// Select the brush into the device context .

CBrush* pOldBrush = pDC—>SelcetObject (&brush);

// Get the area that needs to be erased .

CRect reClip ;

pDC—>GetCilpBox (&rcClip);

//Paint the area.

pDC—> PatBlt (rcClip.left , rcClip.top ,

rcClip.Width ( ) , rcClip.Height ( ) , PATCOPY );

//Unselect brush out of device context .

pDC—>SelectObject (pOldBrush );

// Return nonzero to half fruther processing .

return TRUE;

}
