Visual Style for Windows Explorer hover and selection

Question

The last three versions of Windows have all had translucent highlight and hover effects in Windows Explorer listview:

Using a theme explorer I see that the ListItem has no state that matches what i see in Windows:

Is there a:

• class
• part
• state

that represents the ListView in Windows?

Answer 1

For compatibility reasons ListView still has the old style look by default. DrawThemeBackground(htheme, hdc, LVP_LISTITEM, ...) will simply draw a solid rectangle with border, for all item states, as shown in above image. GetSysColor should be used to get the right colors for this listview.

A call to SetWindowTheme(hwnd, L"Explorer", NULL) will load the new theme data and draw the list items similar to Explorer. Example:

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    switch(msg)
    {
    case WM_CREATE:
        SetWindowTheme(hwnd, L"Explorer", NULL);
        break;
    case WM_PAINT:
    {
        PAINTSTRUCT ps;
        auto hdc = BeginPaint(hwnd, &ps);
        HTHEME ht = OpenThemeData(hwnd, L"LISTVIEW");
        if(ht)
        {
            RECT rc = { 10, 10, 100, 50 };
            DrawThemeBackground(ht, hdc, LVP_LISTITEM, LISS_SELECTED, &rc, NULL); OffsetRect(&rc, 0, 55);
            DrawThemeBackground(ht, hdc, LVP_LISTITEM, LISS_DISABLED, &rc, NULL); OffsetRect(&rc, 0, 55);
            DrawThemeBackground(ht, hdc, LVP_LISTITEM, LISS_SELECTED, &rc, NULL); OffsetRect(&rc, 0, 55);
            DrawThemeBackground(ht, hdc, LVP_LISTITEM, LISS_HOT, &rc, NULL); OffsetRect(&rc, 0, 55);
            DrawThemeBackground(ht, hdc, LVP_LISTITEM, LISS_HOTSELECTED, &rc, NULL); OffsetRect(&rc, 0, 55);
            DrawThemeBackground(ht, hdc, LVP_LISTITEM, LISS_SELECTEDNOTFOCUS, &rc, NULL);
            CloseThemeData(ht);
        }

        EndPaint(hwnd, &ps);
        return 0;
    }
    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;
    }
    return DefWindowProc(hwnd, msg, wParam, lParam);
}

Output:
