# Events Tab

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.

Control Properties

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:

## Подтвердить действие

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.

## Выполнить действие

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.

## Изменено

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

## Текст изменён

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

## Состояние изменено

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

## При получении фокуса

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

## При потере фокуса

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

## Нажатие клавиши

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.

## Отпускание клавиши

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

## Мышь внутри

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

## Перемещение мыши при нажатой клавише

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).

## Перемещение мыши

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

## Нажатие кнопки мыши

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

Обратите внимание на то, что это событие также используется для уведомления о запросах всплывающего контекстного меню в элементе управления.

## Отпускание кнопки мыши

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

## Мышь снаружи

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

### Перед обновлением

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.

### После обновления

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

### Перед восстановлением

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

Форма восстанавливается при выполнении одного из следующих условий.

1. Пользователь нажимает кнопку (HTML), являющуюся кнопкой восстановления.

2. При этом создаётся новая пустая запись в форме, связанной с источником данных. В последней записи, например, можно нажать кнопку Следующая запись.

### После восстановления

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