窗体位置的 x 坐标。
- y
- Int32
窗体位置的 y 坐标。
下面的示例演示如何使用 SetDesktopLocation、 Load 和 Activate 成员。 若要运行该示例，请将以下代码粘贴到名为 Form1 的窗体中，其中包含一个名为 的Button1按钮和两Label个名为 和 Label2的Label1控件。
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 );

桌面坐标基于屏幕的工作区域，这不包括任务栏。 可以使用此方法在桌面上放置窗体。 由于桌面坐标基于窗体的工作区域，因此可以使用此方法确保窗体在桌面上完全可见。 此方法主要用于顶级表单; LayoutMdi 使用 方法将多文档接口定位 (MDI) 子窗体。
