我有一个Windos::Forms::GroupBox它包含一个Windows::Forms::ListView。当我添加项目时,我将项目添加到ListView我告诉它调整大小,但我如何为它的父项GroupBox做同样的事情?如何让Windows :: Forms :: GroupBox调整大小?

[编辑]这是我的自定义调整大小列表控件:

ResizingListView::ResizingListView(void) 
{ 

} 

void ResizingListView::ResizeVerticallyToItems(void) 
{ 
    // Work out the height of the header 
    int headerHeight = 0; 
    int itemsHeight = 0; 
    if(this->Items->Count == 0) 
    { 
     // If no items exist, add one so we can work out how big the header is 
     Items->Add(""); 
     headerHeight = GetHeaderSize(); 
     this->Items->Clear(); 
     itemsHeight = 0; 
    } 
    else 
    { 
     headerHeight = GetHeaderSize(); 
     itemsHeight = this->Items->Count*this->Items[0]->Bounds.Height; 
    } 

    // Work out the overall height and resize to it 
    System::Drawing::Size sz = this->Size; 
    int borderSize = 0; 
    if(this->BorderStyle != System::Windows::Forms::BorderStyle::None) 
    { 
     borderSize = 2; 
    } 
    sz.Height = headerHeight+itemsHeight+borderSize; 
    this->Size = sz; 
} 

int ResizingListView::GetHeaderSize(void) 
{ 
    return Items[0]->Bounds.Top; 
} 

void ResizingListView::OnResize(System::EventArgs^ e) 
{ 
    if(this->Scrollable == false) 
    { 
     ResizeVerticallyToItems(); 
    } 
} 

所以,当我完成aadding项目我打电话ResizeVerticallyToItems()其调整大小没有任何问题的控制。父GroupBox有一些填充,但当我的列表调整大小时会消失。所以我的想法是,我需要问父母GroupBox调整。

这是组框的初始化:

this->grpMyStatus->AutoSize = true; 
this->grpMyStatus->BackColor = System::Drawing::Color::FromArgb(static_cast<System::Int32>(static_cast<System::Byte>(64)), 
    static_cast<System::Int32>(static_cast<System::Byte>(64)), static_cast<System::Int32>(static_cast<System::Byte>(64))); 
this->grpMyStatus->BackgroundImageLayout = System::Windows::Forms::ImageLayout::Stretch; 
this->grpMyStatus->Controls->Add(this->lstMyStatus); 
this->grpMyStatus->Dock = System::Windows::Forms::DockStyle::Top; 
this->grpMyStatus->Font = (gcnew System::Drawing::Font(L"Microsoft Sans Serif", 9.75F, System::Drawing::FontStyle::Bold, 
    System::Drawing::GraphicsUnit::Point, static_cast<System::Byte>(0))); 
this->grpMyStatus->ForeColor = System::Drawing::Color::SkyBlue; 
this->grpMyStatus->Location = System::Drawing::Point(3, 166); 
this->grpMyStatus->Name = L"grpMyStatus"; 
this->grpMyStatus->Padding = System::Windows::Forms::Padding(3, 3, 3, 20); 
this->grpMyStatus->Size = System::Drawing::Size(270, 92); 
this->grpMyStatus->TabIndex = 5; 
this->grpMyStatus->TabStop = false; 
this->grpMyStatus->Text = L"My Status"; 

...这是孩子列表的初始化:

this->lstMyStatus->BackColor = System::Drawing::Color::FromArgb(static_cast<System::Int32>(static_cast<System::Byte>(64)), 
    static_cast<System::Int32>(static_cast<System::Byte>(64)), static_cast<System::Int32>(static_cast<System::Byte>(64))); 
this->lstMyStatus->BorderStyle = System::Windows::Forms::BorderStyle::None; 
this->lstMyStatus->Columns->AddRange(gcnew cli::array<System::Windows::Forms::ColumnHeader^>(1) {this->columnHeader6}); 
this->lstMyStatus->Dock = System::Windows::Forms::DockStyle::Top; 
this->lstMyStatus->Font = (gcnew System::Drawing::Font(L"Verdana", 8.25F, System::Drawing::FontStyle::Bold, System::Drawing::GraphicsUnit::Point, 
    static_cast<System::Byte>(0))); 
this->lstMyStatus->ForeColor = System::Drawing::Color::FromArgb(static_cast<System::Int32>(static_cast<System::Byte>(224)), 
    static_cast<System::Int32>(static_cast<System::Byte>(224)), static_cast<System::Int32>(static_cast<System::Byte>(224))); 
this->lstMyStatus->HeaderStyle = System::Windows::Forms::ColumnHeaderStyle::None; 
this->lstMyStatus->HideSelection = false; 
this->lstMyStatus->Items->AddRange(gcnew cli::array<System::Windows::Forms::ListViewItem^>(3) {listViewItem3, 
    listViewItem4, listViewItem21}); 
this->lstMyStatus->LabelWrap = false; 
this->lstMyStatus->Location = System::Drawing::Point(3, 18); 
this->lstMyStatus->Name = L"lstMyStatus"; 
this->lstMyStatus->RightToLeft = System::Windows::Forms::RightToLeft::Yes; 
this->lstMyStatus->RightToLeftLayout = true; 
this->lstMyStatus->Scrollable = false; 
this->lstMyStatus->ShowGroups = false; 
this->lstMyStatus->ShowItemToolTips = true; 
this->lstMyStatus->Size = System::Drawing::Size(264, 54); 
this->lstMyStatus->SmallImageList = this->imgLights; 
this->lstMyStatus->TabIndex = 18; 
this->lstMyStatus->UseCompatibleStateImageBehavior = false; 
this->lstMyStatus->View = System::Windows::Forms::View::Details; 
this->lstMyStatus->SelectedIndexChanged += gcnew System::EventHandler(this, &Status::lstMyStatus_SelectedIndexChanged);

你可以发布代码示例吗?组件有什么调整策略(GrowAndShrink等),什么是布局,你如何告诉它调整大小?你打电话给PerformLayout()吗? – Stefan 2010-10-14 13:41:48

PerformLayout(在组框)得到它:)如果你添加作为答案我会接受它。 – 2010-10-14 14:24:43

当您将GroupBox的AutoSize属性设置为True时,它会自动进行,它会根据需要增长以适应ListView。这在大多数典型布局中并不常见,因为这会使其容易与其他控件重叠或超出表单边缘。

我们有一些来自某些硬件的状态信息,并且取决于插入了哪些额外的设备,会有更多或更少的信息可用。因此需要调整大小的布局。 – 2010-10-14 14:02:01

那么,不要低估一个滚动条:)但是听起来我还需要使表单自动调整大小。 – 2010-10-14 14:08:34

设置AutoSizetrue为分组框中

好运。
