MapTypeStyle object

VCL TMS VCL WebGMaps

hi,
is it possible to use the google.maps.MapTypeStyle object properties?
with featureType you can define, which elements will be displayed in the map (poi/landscape/transit/...)
https://developers.google.com/maps/documentation/javascript/reference#MapTypeStyle
i can't find it in your component...

Hi,


Unfortunately the MapTypeStyle object properties are currently not supported.
However, this is a good suggestion and we'll consider adding this feature in a future version.

Alternatively some map elements and controls can be enabled/disabled from the ControlsOptions and MapOptions properties.
Please refer to the PDF manual for a full list with descriptions.

that would be great, if you can implement this feature!
i tried "MapOptions.DisablePOI" and found out, that changing it's value at runtime has no effect.
am i missing something?

however, changing "TMapOptions.SetDisablePOI" in UWebGMaps like this is working at runtime:
procedure TMapOptions.SetDisablePOI(const Value: Boolean);
begin
  FDisablePOI := Value;
  if Value then
    FWebGmaps.ExecJScript('map.setOptions( {styles:[{"featureType":"poi","stylers":[{"visibility":"off"}]}]} );')
  else
    FWebGmaps.ExecJScript('map.setOptions( {styles:[{"featureType":"poi","stylers":[{"visibility":"on"}]}]} );')
end;

Hi,


Thank you for your suggestion.
This change will be included with the next release of the TMS VCL WebGMaps.

it would be nice to have all possible map features as a property of TWebGMap.
i wrote a wrapper for ExecJScript to set the features at runtime ... but using the components properties will be the "right" way.
