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 It is, therefore, 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).
