重新计算动态布局属性

这是一个可调整大小的窗口：

设置动态布局属性，以便顶部组框调整宽度大小，下部组/框和树以及 3 个按钮在两个维度上调整大小。

对于高级复选框，我添加了代码来隐藏额外的控件并调整关联框的高度。所以它看起来像这样：

用于切换控制值的代码是：

void CWishListDlg::ToggleAdvancedMode()
{
    CRect rtSortTalk, rtTalkSettings, rtTreeGroup, rtTree, rtTalkCombo;

    m_staticSortTalk.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_cbTalkSortField.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_cbTalkSortOrder.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_staticSortSpeaker.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_cbSpeakerSortField.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_cbSpeakerSortOrder.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_staticTalkHistory.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_checkIncludeTalkHistory.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_staticStyle.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);
    m_cbStyle.ShowWindow(m_bAdvancedMode ? SW_SHOW : SW_HIDE);

    m_staticSortTalk.GetWindowRect(&rtSortTalk);
    m_staticSettings.GetWindowRect(&rtTalkSettings);
    m_staticTreeDetails.GetWindowRect(&rtTreeGroup);
    m_Tree.GetWindowRect(&rtTree);

    if (m_bAdvancedMode)
    {
        rtTalkSettings.bottom += m_iOffsetY;
        rtTreeGroup.top += m_iOffsetY;
        rtTree.top += m_iOffsetY;
    }
    else
    {
        rtTalkSettings.bottom -= m_iOffsetY;
        rtTreeGroup.top -= m_iOffsetY;
        rtTree.top -= m_iOffsetY;
    }

    ScreenToClient(&rtTalkSettings);
    ScreenToClient(&rtTreeGroup);
    ScreenToClient(&rtTree);

    m_staticSettings.MoveWindow(&rtTalkSettings);
    m_staticTreeDetails.MoveWindow(&rtTreeGroup);
    m_Tree.MoveWindow(&rtTree);
}

效果很好。我可以切换到我心满意足的状态。直到我尝试调整窗口大小：

我看不到任何方法来根据活动显示重新计算动态布局属性。

如果选中“高级”，则控件可见（从而与资源编辑器匹配），然后它会很好地调整大小。只有当它未被选中并且我修改了其中两个控件时，调整大小才无法正常工作。

我发现了这个优秀的资源：

您所要做的就是删除动态布局并重新创建它：

void CWishListDlg::SetupDynamicLayout()
{
    // Disable dynamic layout (this will delete the pointer and set it to NULL)
    EnableDynamicLayout(FALSE);

    // Enable dynamic layout (this will create a new pointer with no elements)
    EnableDynamicLayout(TRUE);

    // Re-create the dynamic layout content
    auto pManager = GetDynamicLayout();
    if (pManager != nullptr)
    {
        pManager->Create(this); // Assign the window!
        auto moveNone = CMFCDynamicLayout::MoveNone();
        auto moveVertical100 = CMFCDynamicLayout::MoveVertical(100);
        auto moveBoth100 = CMFCDynamicLayout::MoveHorizontalAndVertical(100, 100);
        auto sizeBoth100 = CMFCDynamicLayout::SizeHorizontalAndVertical(100, 100);
        auto sizeHorizontal100 = CMFCDynamicLayout::SizeHorizontal(100);
        auto sizeNone = CMFCDynamicLayout::SizeNone();

        pManager->AddItem(m_staticSettings.GetSafeHwnd(), moveNone, sizeHorizontal100);
        pManager->AddItem(m_staticTreeDetails.GetSafeHwnd(), moveNone, sizeBoth100);
        pManager->AddItem(m_Tree.GetSafeHwnd(), moveNone, sizeBoth100);
        pManager->AddItem(IDC_BUTTON_HELP, moveVertical100, sizeNone);
        pManager->AddItem(IDC_BUTTON_REPORT, moveBoth100, sizeNone);
        pManager->AddItem(IDC_BUTTON_EXPAND_ALL, moveBoth100, sizeNone);
        pManager->AddItem(IDC_BUTTON_COLLAPSE_ALL, moveBoth100, sizeNone);
        pManager->AddItem(IDC_STATIC_RESIZE, moveBoth100, sizeNone);
    }
}

遗憾的是，您不能只获取布局中现有的控件或告诉它根据活动内容重新初始化。但这种方式效果很好。现在它可以正确调整大小：
