範例

下列程式碼範例會藉由呼叫其 BringToFront 方法,確保可以看見 LabelThe following code example ensures that a Label is visible by calling its BringToFront method. 這個範例需要您具有名為 panel1PanelForm,以及名為 label1LabelThis example requires that you have a Form with a Panel named panel1, and a Label named label1.

private:
   void MakeLabelVisible()
   {
      
      /* If the panel contains label1, bring it
         * to the front to make sure it is visible. */
      if ( panel1->Contains( label1 ) )
      {
         label1->BringToFront();
      }
   }
private void MakeLabelVisible()
{
   /* If the panel contains label1, bring it 
   * to the front to make sure it is visible. */
   if(panel1.Contains(label1))
   {
      label1.BringToFront();
   }
}
Private Sub MakeLabelVisible()
   ' If the panel contains label1, bring it 
   ' to the front to make sure it is visible. 
   If panel1.Contains(label1) Then
      label1.BringToFront()
   End If
End Sub

備註

控制項會移至迭置順序的前方。The control is moved to the front of the z-order. 如果控制項是另一個控制項的子系,則會將子控制項移至迭置順序的前方。If the control is a child of another control, the child control is moved to the front of the z-order. BringToFront 不會將控制項設為最上層控制項,而且不會引發 Paint 事件。BringToFront does not make a control a top-level control, and it does not raise the Paint event.
