Examples
The following code example creates points and sizes using several of the overloaded operators defined for these types. It also demonstrates how to use the
SystemPens
class.
This example is designed to be used with Windows Forms. Create a form that contains a
Button
named
subtractButton
. Paste the code into the form and call the
CreatePointsAndSizes
method from the form's
Paint
event-handling method, passing
e
as
PaintEventArgs
.
void CreatePointsAndSizes( PaintEventArgs^ e )
// Create the starting point.
Point startPoint = Point(subtractButton->Size);
// Use the addition operator to get the end point.
Point endPoint = startPoint + System::Drawing::Size( 140, 150 );
// Draw a line between the points.
e->Graphics->DrawLine( SystemPens::Highlight, startPoint, endPoint );
// Convert the starting point to a size and compare it to the
// subtractButton size.
System::Drawing::Size buttonSize = (System::Drawing::Size)startPoint;
if ( buttonSize == subtractButton->Size )
e->Graphics->DrawString( "The sizes are equal.", gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), Brushes::Indigo, 10.0F, 65.0F );
private void CreatePointsAndSizes(PaintEventArgs e)
// Create the starting point.
Point startPoint = new Point(subtractButton.Size);
// Use the addition operator to get the end point.
Point endPoint = startPoint + new Size(140, 150);
// Draw a line between the points.
e.Graphics.DrawLine(SystemPens.Highlight, startPoint, endPoint);
// Convert the starting point to a size and compare it to the
// subtractButton size.
Size buttonSize = (Size)startPoint;
if (buttonSize == subtractButton.Size)
// If the sizes are equal, tell the user.
e.Graphics.DrawString("The sizes are equal.",
new Font(this.Font, FontStyle.Italic),
Brushes.Indigo, 10.0F, 65.0F);
Private Sub CreatePointsAndSizes(ByVal e As PaintEventArgs)
' Create the starting point.
Dim startPoint As New Point(subtractButton.Size)
' Use the addition operator to get the end point.
Dim endPoint As Point = Point.op_Addition(startPoint, _
New Size(140, 150))
' Draw a line between the points.
e.Graphics.DrawLine(SystemPens.Highlight, startPoint, endPoint)
' Convert the starting point to a size and compare it to the
' subtractButton size.
Dim buttonSize As Size = Point.op_Explicit(startPoint)
If (Size.op_Equality(buttonSize, subtractButton.Size)) Then
' If the sizes are equal, tell the user.
e.Graphics.DrawString("The sizes are equal.", _
New Font(Me.Font, FontStyle.Italic), _
Brushes.Indigo, 10.0F, 65.0F)
End If
End Sub
To convert a
Point
to a
PointF
, use
