ENTRY OnMouseMove(IN INT _refId, IN INT _X, IN INT _Y)
; script actions
END OnMouseMove
Special handler:
ENTRY XXX_OnMouseMove(IN INT _X, IN INT _Y)
; script actions
END XXX_OnMouseMove
Parameters
_refId
Parameter of INT type (required for
global handler).
XXX
Name of Reference variable connected to graphic object (without the character "_").
_Y
Parameter of INT type.
_Y
Parameter of INT type.
Description
The picture event sends information about movement of mouse pointer in
picture for script. When the mouse pointer moves over the graphic objects,
windows controls and displayers Alarm, Browser, Graph and
Logging, x, y
coordinates, when moving over the graphic objects, correspond to the place
in the picture. Otherwise, they correspond to the position in the inserted
window control.
The parameter _refId is used for graphic
objects with defined Reference variable other than 0. So it is possible
to use the special event handler. For the graphic object with no defined
Reference variable, it is required to use the global event handler and the
parameter _refId will be 0. Also when the user
press the mouse button above the picture (not above graphic object).
Example
Global picture event handler:
ENTRY OnMouseMove(IN INT _refId, IN INT _xPos, IN INT _yPos)
END OnMouseMove
Special picture event handler:
ENTRY TV_OnMouseMove(IN INT _xPos, IN INT _yPos)
END TV_OnMouseMove
