如何分别更改2个静态文本元素的背景颜色,每个元素具有不同的背景颜色
代码:
background1 = CreateWindow("STATIC","",WS_VISIBLE | WS_CHILD , 0,0,800,20, hwnd , NULL, NULL, NULL);
background2 = CreateWindow("STATIC","",WS_VISIBLE | WS_CHILD , 0,70,800,500, hwnd , NULL, NULL, NULL);
case WM_CTLCOLORSTATIC:
{
HDC hdcStatic = (HDC) wParam;
SetTextColor(hdcStatic, RGB(0,0,255));
SetBkColor(hdcStatic, RGB(0,0,255));
if (hbrBkgnd == NULL){
hbrBkgnd = CreateSolidBrush(RGB(0,0,55));
}
return (INT_PTR)hbrBkgnd;
}
break;

lparam包含一个静态控件窗口句柄,因此您可以检查它以确定正在重画哪个控件。
if(reinterpret_cast<::HWND>(lParam) == background1)
{
// set background for control 1...
}
else // set backgrounds for other controls
