如何知道SIZE_RESTORED是否触发了WM_GETMINMAXINFO？

Question

我正在为我的游戏实施窗口限制，我遇到了一个小问题。

我使用此代码设置约束：

case WM_GETMINMAXINFO:
     {
        LPMINMAXINFO p_info = (LPMINMAXINFO)lParam;
        RECT wRect;
        RECT cRect;
        int wWidth;
        int wHeight;
        int cWidth;
        int cHeight;
        int total_border_width;
        int total_border_height;
        POINT wmin, wmax;

        GetWindowRect(hWnd, &wRect);
        GetClientRect(hWnd, &cRect);
        wWidth = wRect.right - wRect.left;
        wHeight = wRect.bottom - wRect.top;
        cWidth = cRect.right - cRect.left;
        cHeight = cRect.bottom - cRect.top;
        total_border_width = wWidth - cWidth;
        total_border_height = wHeight - cHeight;

            wmin.x = (d->min_w > 0) ? d->min_w + (resize_is_restore ? -total_border_width : total_border_width) : p_info->ptMinTrackSize.x;
        wmin.y = (d->min_h > 0) ? d->min_h + total_border_height : p_info->ptMinTrackSize.y;
        wmax.x = (d->max_w > 0) ? d->max_w + total_border_width : p_info->ptMaxTrackSize.x;
        wmax.y = (d->max_h > 0) ? d->max_h + total_border_height : p_info->ptMaxTrackSize.y;

        p_info->ptMinTrackSize = wmin;
        p_info->ptMaxTrackSize = wmax;

            resize_is_restore = false;
     }
     break;

问题是当窗口恢复时没有遵守min_w约束。

我想在这种情况下我需要否定总宽度：

wmin.x = (d->min_w > 0) ? d->min_w + (resize_is_restore ? -total_border_width : total_border_width) : p_info->ptMinTrackSize.x;

不幸的是，我无法设置resize_is_restore，因为WM_SIZE消息是在WM_GETMINMAXINFO之后发送的。有没有办法在设置minmaxinfo之前发现调整大小是由于恢复？

由于

修正了：

    /* Fix for when the window is restored */
    if (cWidth == 0 && cHeight == 0) {
        break;
       }
