Ejemplos
El ejemplo siguiente se muestra cómo utilizar MouseDown, MouseMove, y eventos de MouseUp para dibujar líneas en un control de RectangleShape .Este ejemplo requiere tener un control de RectangleShape denominado RectangleShape1 en un formulario.
Private mousePath = New System.Drawing.Drawing2D.GraphicsPath()
Private Sub RectangleShape2_MouseDown(
ByVal sender As Object,
ByVal e As System.Windows.Forms.MouseEventArgs
) Handles RectangleShape2.MouseDown
Dim mouseDownLocation As 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)
End Sub
Private Sub RectangleShape2_MouseMove(
ByVal sender As Object,
ByVal e As System.Windows.Forms.MouseEventArgs
) Handles RectangleShape2.MouseMove
Dim mouseX As Integer = e.X + RectangleShape2.Left
Dim mouseY As Integer = e.Y + RectangleShape2.Top
' Add a line to the graphics path.
mousePath.AddLine(mouseX, mouseY, mouseX, mouseY)
End Sub
Private Sub RectangleShape2_MouseUp(
ByVal sender As Object,
ByVal e As System.Windows.Forms.MouseEventArgs
) Handles RectangleShape2.MouseUp
Dim 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()
End Sub
Private Sub RectangleShape2_Paint(
ByVal sender As Object,
ByVal e As System.Windows.Forms.PaintEventArgs
) Handles RectangleShape2.Paint
' Draw the line.
e.Graphics.DrawPath(System.Drawing.Pens.DarkRed, mousePath)
End Sub
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);
}
