winapi - 在这种情况下无法控制 CDDS_ITEMPREPAINT| CDDS_SUBITEM：

Question

我正在使用 NM_CUSTOMDRAW 在某些条件下更改树视图项及其子项的颜色。我想单独控制子项，但 dwDrawStage 从来没有遇到这种情况 CDDS_ITEMPREPAINT| CDDS_SUBITEM 我的代码片段在这里：

 LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)

  int wmId, wmEvent;

  TVHITTESTINFO hti;
  char achBuf[100];
  switch (message)
  {
  case WM_CREATE:
 RECT rcClient;  // dimensions of client area 
  // handle to tree-view control 

// Ensure that the common control DLL is loaded. 
InitCommonControls(); 

// Get the dimensions of the parent window's client area, and create 
// the tree-view control. 
GetClientRect(hWnd, &rcClient); 
hwndTV = CreateWindowEx(0,
                        WC_TREEVIEW,

                        0, 
                        rcClient.right,

这将为我的父节点着色，但子节点（子项）保持默认（黑色）并返回 CDRF_NOTIFYSUBITEMDRAW 不起作用。请帮忙！！！
