# Eventos

On the Events tab page you can link macros to events that occur in a form's control fields.

When the event occurs, the linked macro will be called. To assign a macro to an event, press the ... button. The Assign Action dialog opens.

Para acceder a esta orden…

Open context menu of a selected form element - choose Control Properties - Events tab.

Abra la barra de herramientas Diseño de formularios, pulse en el icono Propiedades del control y seleccione la pestaña Eventos.

Depending on the control, different events are available. Only the available events for the selected control and context are listed on the Events tab page.
The following events are defined:

## Aprobar acción

This event takes place before an action is triggered by clicking the control. For example, clicking a "Submit" button initiates a send action; however, the actual "send" process is started only when the When initiating event occurs. The Approve action event allows you to kill the process. If the linked method sends back FALSE, When initiating will not be executed.

## Ejecutar acción

The Execute action event occurs when an action is started. For example, if you have a "Submit" button in your form, the send process represents the action to be initiated.

## Modificado

The Changed event takes place when the control loses the focus and the content of the control has changed since it lost the focus.

## Texto modificado

The Text modified event takes place if you enter or modify a text in an input field.

## Estado modificado

The Item status changed event takes place if the status of the control field has changed, for example, from checked to unchecked.

## Recepción de foco

The When receiving focus event takes place if a control field receives the focus.

## Pérdida de foco

The When losing focus event takes place if a control field loses the focus.

## Tecla pulsada

The Key pressed event occurs when the user presses any key while the control has the focus. This event may be linked to a macro for checking entries.

## Tecla suelta

The Key released event occurs when the user releases any key while the control has the focus.

## Ratón dentro

The Mouse inside event takes place if the mouse is inside the control field.

## Mover ratón por medio del teclado

The Mouse moved while key pressed event takes place when the mouse is dragged while a key is pressed. An example is when, during drag-and-drop, an additional key determines the mode (move or copy).

## Movimiento de ratón

The Mouse moved event occurs if the mouse moves over the control.

## Botón de ratón pulsado

The Mouse button pressed event occurs if the mouse button is pressed while the mouse pointer is on the control.

Observe que este evento también se usa para notificar las solicitudes de menú contextual en el control.

## Botón del ratón suelto

The Mouse button released event occurs if the mouse button is released while the mouse pointer is on the control.

## Ratón fuera

The Mouse outside event takes place when the mouse is outside the control field.

### Antes de actualizar

The Before update event occurs before the control content changed by the user is written into the data source. The linked macro can, for example, prevent this action by returning FALSE.

### Después de actualizar

The After update event occurs after the control content changed by the user has been written into the data source.

### Antes de restablecer

The Prior to reset event occurs before a form is reset. Returning True approves the reset, returning False cancels the operation.

Se restablecerá un formulario cuando se cumpla una de las siguientes condiciones:

1. El usuario pulsa un botón (HTML) que se ha definido como botón Restablecer.

2. Se crea un registro nuevo vacío en un formulario vinculado al origen de datos. Por ejemplo, se puede pulsar el botón Registro siguiente en el último registro.

### Después de restablecer

The After resetting event occurs after a form has been reset.
