因为我不喜欢 ListView 与 Explorer 主题结合报表视图中的网格线的方式，所以我想在网格线打开时关闭主题。问题是，一旦应用了 Explorer 主题，就无法将 ListView 恢复为其原始外观。

我尝试了NULL,L""和L" "作为SetWindowTheme参数的各种组合，但似乎没有任何东西可以修复绘图错误。我已经在 Windows 8 和 10 上进行了测试。

有绘图错误的 ListView

#define WINVER 0x500
#define _WIN32_IE 0x400

#include <windowsx.h>

#include <tchar.h>

HWND hMain;
HWND hList;
UINT Step = 0;

void CALLBACK Steps(HWND h, UINT, UINT_PTR idEvent, DWORD)
{
    switch(++Step)
    {
    case 1:
        SetTimer(h, idEvent, 3333, Steps);
        SetWindowTextA(hMain, "Correct; Narrow selection gap");
        SetFocus(hList);
        break;
    case 2:
        SetWindowTheme(hList, L"Explorer", NULL);
        SetWindowTextA(hMain, "Correct; Narrow selection gap and theme");
        break;
    case 3:
        SetWindowTheme(hList, NULL, NULL); // BUG: This disables the theme but does not fully restore the ListView!
        SetWindowTextA(hMain, "Incorrect; Wide selection gap!");
        break;
    case 4:
        PostQuitMessage(0);
        break;
    }
}
