Gis viewer questions

[jsobon]

Dear support,

I have couple of questions related to GIS object/functionality.
1.) For GIS ewo object (GisViewer_ewo1), is there possible to see zoom factor that is used as variable? I mean, during initialization of panel, map files are loaded, then user can scroll with mouse wheel to zoom in. Can I see „zoom level“,.. or „zoom factor“ that is applied to map?
2.) I would like to implement functionality, that based on change zool level will make some actions. Object GisViewer_ewo1 does not support Change or zoom change event. Is it possible to do something like this with gis viewer object?

Thank you

have a look into the extended properties tab in Gedi. You'll find the ZoomFactorChanged() event script.
There seems to be no property yet to get the current zoom factor.

Hi,

I have one more question. Not sure even if this is possible to do in gisviewer, so I would like to check it.
Could you please tell me if in gisviewer is possible to show on map graphics objects like traffic sign's? Also if those objects could change values/states dynamically and if those objects will have same size when user will zooming.

Yes, it is possible to show Panel References inside the map.
Check the help at qthelp://wincc_oa/doc/Control_Grafik/setShapePVSSSymbol.htm

Thank you!

one more question: Is in GIS possible to add dynamic object to layer (map) to any place (not to shape)?

The shape in the 'setShapePVSSSymbol' can be a point in the layer as the example shows.
