The following code example demonstrates the Document, UseAntiAlias, and Zoom properties of the PrintPreviewControl. To run this example, place the following code in a form and call the InitializePrintPreviewControl
method from the form's constructor or Load event-handling method.
internal:
// Declare the PrintPreviewControl object and the
// PrintDocument object.
PrintPreviewControl^ PrintPreviewControl1;
private:
System::Drawing::Printing::PrintDocument^ docToPrint;
void InitializePrintPreviewControl()
{
// Construct the PrintPreviewControl.
this->PrintPreviewControl1 = gcnew PrintPreviewControl;
// Set location, name, and dock style for PrintPreviewControl1.
this->PrintPreviewControl1->Location = Point(88,80);
this->PrintPreviewControl1->Name = "PrintPreviewControl1";
this->PrintPreviewControl1->Dock = DockStyle::Fill;
// Set the Document property to the PrintDocument
// for which the PrintPage event has been handled.
this->PrintPreviewControl1->Document = docToPrint;
// Set the zoom to 25 percent.
this->PrintPreviewControl1->Zoom = 0.25;
// Set the document name. This will show be displayed when
// the document is loading into the control.
this->PrintPreviewControl1->Document->DocumentName = "c:\\someFile";
// Set the UseAntiAlias property to true so fonts are smoothed
// by the operating system.
this->PrintPreviewControl1->UseAntiAlias = true;
// Add the control to the form.
this->Controls->Add( this->PrintPreviewControl1 );
// Associate the event-handling method with the
// document's PrintPage event.
this->docToPrint->PrintPage += gcnew System::Drawing::Printing::PrintPageEventHandler( this, &Form1::docToPrint_PrintPage );
}
