事件

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.

若要使用此指令...

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

Open Form Controls toolbar or Form Design toolbar, click Control 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:

核准動作

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.

執行動作

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.

已經修改

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

文字已經修改

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

狀態已經變更

The Item status changed event takes place if the status of the control field has changed.

在瞄準時

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

在偏離目標時

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

在按下按鍵後

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.

放開按鍵

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

滑鼠進入

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

按下按鍵時移動滑鼠

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).

滑鼠移動

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

按住滑鼠鍵

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

評註圖示

請注意,此事件也可用來通知要求控制項上出現快顯右鍵功能表。


放開滑鼠鍵

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

滑鼠移出

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

在更新之前

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".

更新之後

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

在重設之前

The Prior to reset event occurs before a form is reset. The linked macro can, for example, prevent this action by returning "FALSE".

如果進入下述條件之一,則會重設表單:

  1. 使用者按下一個定義為「Reset」的 (HTML) 按鈕

  2. 在連結至資料源的表單中建立新的空白資料條目。例如,在最後一個資料條目中按[下一個資料條目]按鈕。

重設之後

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