This chapter contains these topics:


DragDrop Event

Applies To

Oracle Data Control

Description

Occurs when a drag-and-drop operation is completed as a result of either dragging a control over a form or control and releasing the mouse button, or using the Drag method with its action argument = 2 (Drop).


DragOver Event

Applies To

Oracle Data Control

Description

Occurs when a drag-and-drop operation is in progress. You can use this event to monitor when the mouse pointer enters, leaves, or is directly over a valid target. The mouse pointer position determines which target object receives this event.


Error Event

Applies To

Oracle Data Control

Description

This event is fired whenever an interactive operation causes an error. You can perform some operations directly with the data control, such as using the data control buttons or when the data control refreshes automatically when the form loads. In these cases, the Error event is fired instead of causing a normal run-time error.


MouseDown Event

Applies To

Oracle Data Control

Description

This event is fired whenever a mouse button is pressed (MouseDown) and the mouse pointer is over the data control, or has been captured by the data control. The mouse is captured if a mouse button has been pressed previously over the data control until all corresponding MouseUp events have been received.


MouseMove Event

Applies To

Oracle Data Control

Description

This event is fired continuously whenever the mouse pointer moves across the data control. Unless another object has not captured the mouse, the data control recognizes a MouseMove event whenever the mouse position is within its borders.


MouseUp Event

Applies To

Oracle Data Control

Description

This event is fired whenever a mouse button is released (MouseUp) and the mouse pointer is over the data control, or has been captured by the data control. The mouse is captured if a mouse button has been pressed previously over the data control until all corresponding MouseUp events have been received.


Reposition Event

Applies To

Oracle Data Control

Description

This event is fired whenever the database record pointer is successfully repositioned to a new location. The Validate event is always fired before Reposition.


Validate Event

Applies To

Oracle Data Control

Description

This method is called whenever a variety of circumstances occur. It is sent when an attempt is made to move to a new record position, to delete a record, add a record, move to a bookmark, or to roll back the dynasets in the session. Validate is always called before the operation proceeds and any action is taken.
