示例

下面的代码示例创建GroupBox和设置的某些常见属性。The following code example creates a GroupBox and sets some of its common properties. 此示例将创建TextBox,并设置其Location组框中。The example creates a TextBox and sets its Location within the group box. 接下来,设置Text停靠此分组框到窗体顶部的分组框的属性。Next, it sets the Text property of the group box, and docks the group box to the top of the form. 最后,通过设置禁用分组框Enabled属性设置为false,这将导致要禁用的组框中包含的所有控件。Lastly, it disables the group box by setting the Enabled property to false, which causes all controls contained within the group box to be disabled.

   // Add a GroupBox to a form and set some of its common properties.
private:
   void AddMyGroupBox()
   {
      // Create a GroupBox and add a TextBox to it.
      GroupBox^ groupBox1 = gcnew GroupBox;
      TextBox^ textBox1 = gcnew TextBox;
      textBox1->Location = Point(15,15);
      groupBox1->Controls->Add( textBox1 );

      // Set the Text and Dock properties of the GroupBox.
      groupBox1->Text = "MyGroupBox";
      groupBox1->Dock = DockStyle::Top;

      // Disable the GroupBox (which disables all its child controls)
      groupBox1->Enabled = false;

      // Add the Groupbox to the form.
      this->Controls->Add( groupBox1 );
   }
// Add a GroupBox to a form and set some of its common properties.
private void AddMyGroupBox()
{
   // Create a GroupBox and add a TextBox to it.
   GroupBox groupBox1 = new GroupBox();
   TextBox textBox1 = new TextBox();
   textBox1.Location = new Point(15, 15);
   groupBox1.Controls.Add(textBox1);

   // Set the Text and Dock properties of the GroupBox.
   groupBox1.Text = "MyGroupBox";
   groupBox1.Dock = DockStyle.Top;

   // Disable the GroupBox (which disables all its child controls)
   groupBox1.Enabled = false;

   // Add the Groupbox to the form.
   this.Controls.Add(groupBox1);
}
' Add a GroupBox to a form and set some of its common properties.
Private Sub AddMyGroupBox()
   ' Create a GroupBox and add a TextBox to it.
   Dim groupBox1 As New GroupBox()
   Dim textBox1 As New TextBox()
   textBox1.Location = New Point(15, 15)
   groupBox1.Controls.Add(textBox1)
   
   ' Set the Text and Dock properties of the GroupBox.
   groupBox1.Text = "MyGroupBox"
   groupBox1.Dock = DockStyle.Top
   
   ' Disable the GroupBox (which disables all its child controls)
   groupBox1.Enabled = False
   
   ' Add the Groupbox to the form.
   Me.Controls.Add(groupBox1)
End Sub

注解

因为Point类是值类型 (Structure在 Visual Basic 中structVisual C# 中),它返回的值,这意味着访问的属性返回的控件的左上角点副本。Because the Point class is a value type (Structure in Visual Basic, struct in Visual C#), it is returned by value, meaning accessing the property returns a copy of the upper-left point of the control. 因此,调整XY的属性Point返回此属性将不会影响LeftRightTop,或Bottom控件的属性值。So, adjusting the X or Y properties of the Point returned from this property will not affect the Left, Right, Top, or Bottom property values of the control. 若要调整这些属性分别设置每个属性值,或设置Location具有一个新属性PointTo adjust these properties set each property value individually, or set the Location property with a new Point.

如果ControlForm,则Location属性值表示的左上角Form屏幕坐标中。If the Control is a Form, the Location property value represents the upper-left corner of the Form in screen coordinates.
