DragStarting Event, SftMask Object

The beginning of a drag & drop operation has been detected.

Syntax

object

A SftMask object.

Button

Describes the button(s) that are pressed. The Button argument is a bit field with bits corresponding to the left button, right button and middle button. These bits correspond to the values shown below. The bits set indicate the button that caused the event.

Shift

Describes the state of the SHIFT, CONTROL and ALT keys. A bit is set if the key is down. The Shift argument is a bit field with bits corresponding to the SHIFT, CONTROL and ALT keys. It indicates the state of these keys. Some, all, or none of the bits can be set, indicating which of the keys are pressed.

x

The x coordinate of the mouse cursor, in pixels, relative to the top left corner of the control.

y

The y coordinate of the mouse cursor, in pixels, relative to the top left corner of the control.

Comments

The DragStarting event occurs when the beginning of a drag & drop operation has been detected.

The DragStarting event only occurs when a drag & drop operation is detected and the OLEDragMode property is set to OLEDragSftMaskManual. A drag & drop operation is initiated by pressing the left mouse button on the current selection.

The application can start an OLE drag & drop operation in response to other events by using the OLEDrag method.
