MouseButtons (Enumeración)

Especifica las constantes que definen qué botón del mouse (ratón) se ha presionado.

La enumeración tiene un atributo FlagsAttribute que permite una combinación bit a bit de los valores de miembro.

 Nombre de miembroDescripción
Compatible con .NET Compact FrameworkLeftSe presionó el botón primario del mouse. 
Compatible con .NET Compact FrameworkMiddleSe presionó el botón central del mouse. 
Compatible con .NET Compact FrameworkNoneNo se presionó ningún botón del mouse. 
Compatible con .NET Compact FrameworkRightSe presionó el botón secundario del mouse. 
XButton1Se presionó el primer botón XButton. 

Con Windows 2000, Microsoft introduce compatibilidad con Microsoft IntelliMouse Explorer, que es un mouse con cinco botones. Los dos nuevos botones del mouse (XBUTTON1 y XBUTTON2) permiten el desplazamiento hacia atrás y hacia delante.

XButton2Se presionó el segundo botón XButton. 

Con Windows 2000, Microsoft introduce compatibilidad con Microsoft IntelliMouse Explorer, que es un mouse con cinco botones. Los dos nuevos botones del mouse (XBUTTON1 y XBUTTON2) permiten el desplazamiento hacia atrás y hacia delante.

Esta enumeración es utilizada por numerosas clases, incluidas AxHost, Control, DataGrid, Form, RadioButton, Splitter, StatusBar y UpDownBase.

En el siguiente ejemplo se muestra la forma de utilizar el método GetCharFromPosition para obtener un carácter contenido en un control RichTextBox a partir de sus coordenadas de control. En el código de ejemplo se utilizan coordenadas ubicadas en el objeto MouseEventArgs que se ha pasado como parámetro al controlador de eventos para determinar la ubicación del control en la que se va a obtener el carácter. A continuación, el carácter se muestra en MessageBox siempre que éste no sea un espacio. En este ejemplo se supone que se ha creado un control RichTextBox denominado richTextBox1 y que el código de ejemplo está conectado al evento MouseDown del control RichTextBox.

private void richTextBox1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
    // Determine which mouse button is clicked.
    if(e.Button == MouseButtons.Left)
    {
        // Obtain the character at which the mouse cursor was clicked at.
        char tempChar = richTextBox1.GetCharFromPosition(new Point(e.X, e.Y));
        // Determine whether the character is an empty space.
        if (tempChar.ToString() != " ")
            // Display the character in a message box.
            MessageBox.Show("The character at the specified position is " + tempChar + ".");

    }
}

private void richTextBox1_MouseDown(Object sender, System.Windows.
    Forms.MouseEventArgs e)
{
    // Determine which mouse button is clicked.
    if (e.get_Button().Equals(get_MouseButtons().Left)) {
        // Obtain the character at which the mouse cursor was clicked at.
        char tempChar = richTextBox1.GetCharFromPosition(new Point(e.
             get_X(), e.get_Y()));
        // Determine whether the character is an empty space.
        if (!(((System.Char)tempChar).ToString().Equals(" "))) {
            // Display the character in a message box.
            MessageBox.Show("The character at the specified position is " 
                + tempChar + ".");
        }
    }
} //richTextBox1_MouseDown 

En el siguiente ejemplo se muestra cómo utilizar distintos eventos de mouse para dibujar el trazo del ratón en Panel. Se agrega un segmento de línea a GraphicsPath para cada uno de los eventos MouseMove y MouseDown que se produzcan. Para actualizar los gráficos, se llama al método Invalidate para Panel en cada evento MouseDown y MouseUp. Además, el trazado del gráfico se desplaza hacia arriba o hacia abajo cuando se produce el evento MouseWheel. Otros eventos de mouse, como MouseHover, también se identifican en la pantalla. Asimismo, en la pantalla se muestra información adicional sobre el mouse desde la clase SystemInformation.
