YStart Attribute
Data Type: integer
4GL Access: R
The YStart attribute specifies one of the following values:
• For the ClickPoint event, the y-coordinate of the point that was clicked
• For the DragBox event, the uppermost y-coordinate of the drag box
• For the DragSegment event, the starting y-coordinate of the user drag
For all other events, this attribute has no meaning and is set to zero. All coordinates are measured relative to the trigger field (the field on which the event was triggered).
You can use this attribute with the XStart, XEnd, and YEnd attributes to determine the position of a click or the extent of a drag.
