C 如何将ListView复选框与所选内容同步？（WIN32）

我正在编写一个简单的Win32程序，该程序有一个启用复选框和多行选择的ListView：

复选框检查和行选择似乎是两种截然不同的行为。是否有一种同步这两种行为的方法，即每当选中一个复选框时，该行将被选中；每当选中一行时，相应的复选框将被选中？

“每当选中一行时，相应的复选框将被选中”

选中并

LVIS_SELECTED

标记，以便在用户选择行时进行检测。和用于选中复选框：

BOOL CALLBACK DialogProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    static HWND hListView;
    switch (msg)
    {
    case WM_INITDIALOG:
        hListView = GetDlgItem(hWnd, IDC_LIST1);
        break;

    case WM_NOTIFY:
    {
        NMHDR* header = (NMHDR*)lParam;
        NMLISTVIEW* nmlist = (NMLISTVIEW*)lParam;
        if (header && header->idFrom == IDC_LIST1 && header->code == LVN_ITEMCHANGED)
            if (nmlist->uNewState & LVIS_SELECTED)
                ListView_SetCheckState(hListView, nmlist->iItem, 1);
        break;
    }
    ...
}

“无论何时选中复选框，都将选中该行”

选中

WM\u NOTIFY

和

LVIS\u statemagemask

标志以检测何时选中复选框，然后使用

ListView\u SetItemState

选择行

这也会导致递归调用，因为我们更改行以响应复选框，并且更改复选框以响应行选择。使用

busy

变量停止递归调用

case WM_NOTIFY:
    if (lParam)
    {
        NMHDR* header = (NMHDR*)lParam;
        NMLISTVIEW* nmlist = (NMLISTVIEW*)lParam;

        //use `busy` as a flag to prevent recursive calls:
        static BOOL busy = FALSE;
        if (!busy && header->hwndFrom == hListView && header->code == LVN_ITEMCHANGED)
        {
            busy = TRUE;
            if (nmlist->uNewState & LVIS_SELECTED)
            {
                //row has been selected => check the checkbox
                ListView_SetCheckState(hListView, nmlist->iItem, 1);
            }
            else if (nmlist->uNewState & LVIS_STATEIMAGEMASK)
            {
                //checkbox has been changed => select/unselect the row
                BOOL checked = ListView_GetCheckState(hListView, nmlist->iItem);
                ListView_SetItemState(hListView, nmlist->iItem,
                     checked ? LVIS_SELECTED : 0, LVIS_SELECTED);
            }
            busy = FALSE;
        }
    }
    break;
