# 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 orde...

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

Open Form Design toolbar, click Control Properties icon - Events tab.

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 unha 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.

## Executar unha 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.

## Ao recibir o foco

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

## Ao perder o foco

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

## Tecla premida

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 liberada

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

## Rato dentro

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

## Movemento do rato con tecla premida

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).

## Movemento do rato

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

## Botón do rato premido

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

Note that this event is also used for notifying requests for a popup context menu on the control.

## Botón do rato liberado

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

## Rato fóra

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.

### Despois de actualizar

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

### Antes de restaurar

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

O formulario restáurase cando se dá algunha destas condicións:

1. O usuario preme nun botón (HTML) definido como botón de restauración.

2. Créase un rexistro baleiro nun formulario ligado a unha fonte de datos. Por exemplo, no último rexistro pódese premer no botón Seguinte rexistro.

### Despois de restaurar

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