Form.AddOwnedForm 方法

向此窗体添加附属窗体。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Sub AddOwnedForm ( _
    ownedForm As Form _
)
用法
Dim instance As Form
Dim ownedForm As Form

instance.AddOwnedForm(ownedForm)

public void AddOwnedForm (
    Form ownedForm
)

public:
void AddOwnedForm (
    Form^ ownedForm
)

public void AddOwnedForm (
    Form ownedForm
)

public function AddOwnedForm (
    ownedForm : Form
)

参数

• ownedForm
  此窗体将拥有的 Form。

备注

分配给所有者窗体的窗体将保持被拥有状态，直到调用了 RemoveOwnedForm 方法。还可以让一个窗体归另一窗体所有，方法是设置带有对其所有者窗体的引用的 Owner 属性。

当一个窗体归另一窗体所有时，它便随着所有者窗体最小化和关闭。例如，如果 Form2 归窗体 Form1 所有，则关闭或最小化 Form1 时，Form2 也会关闭或最小化。并且附属窗体从不显示在其所有者窗体后面。可以将附属窗体用于查找和替换窗口之类的窗口；当所有者窗体被选定时，这些窗口不应显示在所有者窗体后。

提示

如果窗体是多文档界面 (MDI) 父窗体，则除了当前打开的所有 MDI 子窗体外，此属性返回所有显示的窗体。若要获得 MDI 父窗体中打开的 MDI 子窗体，请使用 MdiChildren 属性。

示例

下面的代码示例演示如何使用 AddOwnedForm 方法将某个窗体显示为另一窗体的附属窗体。一旦显示附属窗体后，即可将该附属窗体的所有者窗体最小化，并且附属窗体也将随之最小化。此示例要求从窗体的另一事件或方法调用示例中的代码。

Private Sub ShowMyOwnedForm()
   ' Create an instance of the form to be owned.
   Dim ownedForm As New Form()
   ' Set the text of the form to identify it is an owned form.
   ownedForm.Text = "Owned Form"
   ' Add ownedForm to array of owned forms.
   Me.AddOwnedForm(ownedForm)

   ' Show the owned form.
   ownedForm.Show()
End Sub

private void ShowMyOwnedForm()
{
   // Create an instance of the form to be owned.
   Form ownedForm = new Form();
   // Set the text of the form to identify it is an owned form.
   ownedForm.Text = "Owned Form";
   // Add ownedForm to array of owned forms.
   this.AddOwnedForm(ownedForm);

   // Show the owned form.
   ownedForm.Show();
}

private:
   void ShowMyOwnedForm()
   {
      // Create an instance of the form to be owned.
      Form^ ownedForm = gcnew Form;

      // Set the text of the form to identify it is an owned form.
      ownedForm->Text = "Owned Form";

      // Add ownedForm to array of owned forms.
      this->AddOwnedForm( ownedForm );

      // Show the owned form.
      ownedForm->Show();
   }

private void ShowMyOwnedForm()
{
    // Create an instance of the form to be owned.
    Form ownedForm = new Form();

    // Set the text of the form to identify it is an owned form.
    ownedForm.set_Text("Owned Form");

    // Add ownedForm to array of owned forms.
    this.AddOwnedForm(ownedForm);

    // Show the owned form.
    ownedForm.Show();
} //ShowMyOwnedForm
