示例

下面的代码示例演示如何使用SetDesktopLocationLoadActivate成员。The following code example demonstrates how to use the SetDesktopLocation, Load and Activate members. 若要运行该示例,请将以下代码粘贴在一个称为窗体Form1包含一个按钮调用Button1并将两个Label控件称为Label1Label2To run the example, paste the following code in a form called Form1 containing a button called Button1 and two Label controls called Label1 and Label2.

static int x = 200;
static int y = 200;
void Button1_Click( System::Object^ sender, System::EventArgs^ e )
{
   
   // Create a new Form1 and set its Visible property to true.
   Form1^ form2 = gcnew Form1;
   form2->Visible = true;
   
   // Set the new form's desktop location so it  
   // appears below and to the right of the current form.
   form2->SetDesktopLocation( x, y );
   x += 30;
   y += 30;
   
   // Keep the current form active by calling the Activate
   // method.
   this->Activate();
   this->Button1->Enabled = false;
}


// Updates the label text to reflect the current values of x 
// and y, which was were incremented in the Button1 control's 
// click event.
void Form1_Activated( Object^ sender, System::EventArgs^ e )
{
   Label1->Text = String::Format( "x: {0} y: {1}", x, y );
   Label2->Text = String::Format( "Number of forms currently open: {0}", count );
}

static int count = 0;
void Form1_Closed( Object^ sender, System::EventArgs^ e )
{
   count -= 1;
}

void Form1_Load( Object^ sender, System::EventArgs^ e )
{
   count += 1;

	// appears below and to the right of the current form.

注解

桌面坐标相对于屏幕,其中不包括任务栏的工作区。Desktop coordinates are based on the working area of the screen, which excludes the taskbar. 此方法可用于在桌面上定位你的窗体。You can use this method to position your form on the desktop. 因为桌面坐标基于窗体的工作区,可以使用此方法以确保你的窗体是完全在桌面上可见。Since desktop coordinates are based on the working area of the form, you can use this method to ensure that your form is completely visible on the desktop. 此方法应主要用于顶级窗体;使用LayoutMdi方法来定位多文档界面 (MDI) 子窗体。This method is intended to be used primarily for top-level forms; use the LayoutMdi method to position multiple-document interface (MDI) child forms.
