示例

下面的代码示例创建一个GroupBox并设置它的一些公共属性。The following code example creates a GroupBox and sets some of its common properties. 该示例创建一个TextBox ,并在Location组框中设置它。The example creates a TextBox and sets its Location within the group box. 接下来,它设置Text组框的属性,并将组框停靠到窗体的顶部。Next, it sets the Text property of the group box, and docks the group box to the top of the form. 最后,它通过将Enabled属性设置为来false禁用分组框,这将导致禁用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

由于类是值类型(Structure在 Visual Basic 中, struct在 Visual C#中为),因此它按值返回,这意味着访问属性将返回控件左上角的副本。 PointBecause 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. X因此,调整从此属性Y返回的的Point或属性将不会影响该控件LeftRightTop、或Bottom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,请分别设置每个属性值Location ,或使用新Point的设置属性。To adjust these properties set each property value individually, or set the Location property with a new Point.

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