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

Text每个派生类以不同的方式使用该控件的属性。The Text property of the control is used differently by each derived class. 例如Text属性的Form显示在窗体顶部的标题栏中,字符数,在很小,通常显示的应用程序或文档的名称。For example the Text property of a Form is displayed in the title bar at the top of the form, is fairly small in character count, and usually displays the application or document name. 但是,Text属性的RichTextBox可以很大,并且可以包含大量用于设置文本格式的不可见字符。However, the Text property of a RichTextBox can be large and can include numerous nonvisual characters used to format the text. 例如,在显示的文本RichTextBox可通过调整格式设置Font属性,或通过添加空格或制表符来对齐文本。For example, the text displayed in a RichTextBox can be formatted by adjusting the Font properties, or by the addition of spaces or tab characters to align the text.

继承者说明

重写时Text属性在派生类中,使用基类的Text属性扩展的基实现。When overriding the Text property in a derived class, use the base class's Text property to extend the base implementation. 否则,必须提供所有的实现。Otherwise, you must provide all the implementation. 不需要重写二者getset访问器Text属性; 您可以根据需要覆盖只有一个。You are not required to override both the get and set accessors of the Text property; you can override only one if needed.
