Shape.Paint Event

Occurs when the shape is redrawn.

Namespace:  Microsoft.VisualBasic.PowerPacks
Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

[BrowsableAttribute(true)]
public event PaintEventHandler Paint

The Paint event handler is typically used to perform custom drawing when a shape is redrawn.

For more information about how to handle events, see Consuming Events.

The following example shows how to use the Paint event to draw lines on a RectangleShape control. This example requires that you have a RectangleShape control named RectangleShape1 on a form.

private System.Drawing.Drawing2D.GraphicsPath mousePath = 
    new System.Drawing.Drawing2D.GraphicsPath();

private void rectangleShape2_MouseDown(object sender, 
    System.Windows.Forms.MouseEventArgs e)
{
    Point mouseDownLocation = new Point(e.X + rectangleShape2.Left, 
        e.Y + rectangleShape2.Top);
    // Clear the previous line.
    mousePath.Dispose();
    mousePath = new System.Drawing.Drawing2D.GraphicsPath();
    rectangleShape2.Invalidate();
    // Add a line to the graphics path.
    mousePath.AddLine(mouseDownLocation, mouseDownLocation);
}

private void rectangleShape2_MouseMove(object sender, 
    System.Windows.Forms.MouseEventArgs e)
{
    int mouseX = e.X + rectangleShape2.Left;
    int mouseY = e.Y + rectangleShape2.Top;
    // Add a line to the graphics path.
    mousePath.AddLine(mouseX, mouseY, mouseX, mouseY);
}

private void rectangleShape2_MouseUp(object sender, 
    System.Windows.Forms.MouseEventArgs e)
{
    System.Drawing.Point mouseUpLocation = 
        new System.Drawing.Point(e.X + rectangleShape2.Left, 
            e.Y + rectangleShape2.Top);
    // Add a line to the graphics path.
    mousePath.AddLine(mouseUpLocation, mouseUpLocation);
    // Force the shape to redraw.
    rectangleShape2.Invalidate();
}

private void rectangleShape2_Paint(object sender, 
    System.Windows.Forms.PaintEventArgs e)
{
    // Draw the line.
    e.Graphics.DrawPath(System.Drawing.Pens.DarkRed, mousePath);
}
