示例

下面的代码示例将添加Button到窗体中,并设置其一些公共属性。The following code example adds a Button to a form and sets some of its common properties. 该示例将按钮锚定在窗体右下角,以便在调整窗体大小时保持其相对位置。The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. 接下来,它BackgroundImage将设置按钮的大小,并将其大小Image调整为与相同。Next it sets the BackgroundImage and resizes the button to the same size as the Image. 然后,该示例将TabStop设置true为并设置TabIndex属性。The example then sets the TabStop to true and sets the TabIndex property. 最后,它会添加一个事件处理程序来Click处理该按钮的事件。Lastly, it adds an event handler to handle the Click event of the button. 此示例要求您具有ImageList名为imageList1的。This example requires that you have an ImageList named imageList1.

   // Add a button to a form and set some of its common properties.
private:
   void AddMyButton()
   {
      // Create a button and add it to the form.
      Button^ button1 = gcnew Button;

      // Anchor the button to the bottom right corner of the form
      button1->Anchor = static_cast<AnchorStyles>(AnchorStyles::Bottom | AnchorStyles::Right);

      // Assign a background image.
      button1->BackgroundImage = imageList1->Images[ 0 ];

      // Specify the layout style of the background image. Tile is the default.
      button1->BackgroundImageLayout = ImageLayout::Center;

      // Make the button the same size as the image.
      button1->Size = button1->BackgroundImage->Size;

      // Set the button's TabIndex and TabStop properties.
      button1->TabIndex = 1;
      button1->TabStop = true;

      // Add a delegate to handle the Click event.
      button1->Click += gcnew System::EventHandler( this, &Form1::button1_Click );

      // Add the button to the form.
      this->Controls->Add( button1 );
   }
// Add a button to a form and set some of its common properties.
private void AddMyButton()
{
   // Create a button and add it to the form.
   Button button1 = new Button();

   // Anchor the button to the bottom right corner of the form
   button1.Anchor = (AnchorStyles.Bottom | AnchorStyles.Right);

   // Assign a background image.
   button1.BackgroundImage = imageList1.Images[0];

   // Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center;
   
   // Make the button the same size as the image.
   button1.Size = button1.BackgroundImage.Size;

   // Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1;
   button1.TabStop = true;

   // Add a delegate to handle the Click event.
   button1.Click += new System.EventHandler(this.button1_Click);

   // Add the button to the form.
   this.Controls.Add(button1);
}
' Add a button to a form and set some of its common properties.
Private Sub AddMyButton()
   ' Create a button and add it to the form.
   Dim button1 As New Button()
   
   ' Anchor the button to the bottom right corner of the form
   button1.Anchor = AnchorStyles.Bottom Or AnchorStyles.Right
   
   ' Assign a background image.
   button1.BackgroundImage = imageList1.Images(0)

   ' Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center
   
   ' Make the button the same size as the image.
   button1.Size = button1.BackgroundImage.Size
   
   ' Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1
   button1.TabStop = True

   ' Add a delegate to handle the Click event.
   AddHandler button1.Click, AddressOf Me.button1_Click
   
   ' Add the button to the form.
   Me.Controls.Add(button1)
End Sub

注解

当用户按 TAB 键时,输入焦点设置为 TAB 键顺序中的下一个控件。When the user presses the TAB key, the input focus is set to the next control in the tab order. 属性值为的false控件不包括在 tab 键顺序中的控件集合中。 TabStopControls with the TabStop property value of false are not included in the collection of controls in the tab order. 可以通过设置控件的TabIndex属性值来操作 tab 键顺序。The tab order can be manipulated by setting the control's TabIndex property value.
