Esempio
Nell'esempio di codice seguente viene illustrato l'uso della PrimaryScreen proprietà e del GetWorkingArea metodo . Questo metodo richiede un modulo contenente un pulsante denominato Button1
.
// This method will adjust the size of the form to utilize
// the working area of the screen.
private:
void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
// Retrieve the working rectangle from the Screen class
// using the PrimaryScreen and the WorkingArea properties.
System::Drawing::Rectangle workingRectangle = Screen::PrimaryScreen->WorkingArea;
// Set the size of the form slightly less than size of
// working rectangle.
this->Size = System::Drawing::Size( workingRectangle.Width - 10, workingRectangle.Height - 10 );
// Set the location so the entire form is visible.
this->Location = System::Drawing::Point( 5, 5 );
}
// This method will adjust the size of the form to utilize
// the working area of the screen.
private void Button1_Click(System.Object sender, System.EventArgs e)
{
// Retrieve the working rectangle from the Screen class
// using the PrimaryScreen and the WorkingArea properties.
System.Drawing.Rectangle workingRectangle =
Screen.PrimaryScreen.WorkingArea;
// Set the size of the form slightly less than size of
// working rectangle.
this.Size = new System.Drawing.Size(
workingRectangle.Width-10, workingRectangle.Height-10);
// Set the location so the entire form is visible.
this.Location = new System.Drawing.Point(5, 5);
