Hello, did you set your own Google API Key ?
(The corresponding constant is MyGoogleAPIKey)
You can get your key at https://code.google.com/apis/console/

Dear All,
Can teach me how to use this component in UNIGUI, ?
1. retrieve the postal code from the address.
2. Calculate the distance between two address.
Thanks in advance.
Hello,
1. You can try reverse geocoding.
2. Use the included Haversine formula
function TUniGMap.ComputeDistanceBetween(lat1, lng1, lat2, lng2: Double): Double;

Hello,
I uploaded a new version which implements the API method getBounds.The getBounds returns the lat/lng bounds of the current viewport.
// swlat,swlng : south-west coordinates (Bottom-Left) // nelat,nelng : north-east coordinates (Top-Right)

Hello everyone.
I need to get the upper left point (Lat, Long) and the lower right point of the map that is being displayed, any idea how to do it.

You can use the procedure getBounds (implemented in the latest v1.4.8).

Dear Lema,
Is there any function to know if a point is contained in a kml polygon?
Thank's
Hello.
AFAIK, there is no any Google Maps API function to solve the Point-In-Polygon problem.
You have to find a suitable algorithm via searching the internet.
You can try:
https://www.google.gr/search?q=Point-In-Polygon
https://gis.stackexchange.com/search?q=Point-In-Polygon
Personally, I have used the spatial functions of MySQL.

Dear Lema, First of all thank you very much for your help!!! I have a KML file loaded ok, with several polygons, my question is it possible to search for a particular polygon, can it be searched for by some characteristic? Thank you so much
mmurgas
Hello
- please correct me if I am mistaken -
but I don’t have see any Google Maps API call for searching in KML Layers.
Why don't you parse and traverse the KML file like any other XML?

Hi
What causes this error ?
In a existing project my gmap works, in new one
i got this message
regards Peter
Hello, is the problem solved ?
In general :
When the component is being created, it adds the necessary paths in ServerModule.CustomFiles.
So, there must be an instance of uniGmap on your FIRST form.
I always suggest to place an invisible uniGmap on your MainForm or LoginForm.
Also, please make sure that you have the required JS files in the /files directory
markerclusterer.js
markerwithlabel_packed.js

%2011.44.24.png)
Theres any way to do some like this? markers with numbers inside? The image is from devexpress library.Best regards.
You can try to customize your marker with CSS.
See at the demo->Markers with Label

Hello,
I uploaded a new version which implements the API method fitBounds.The fitBounds sets the viewport to contain the given bounds.
procedure TUniGMap.fitBounds(sw, ne: TPoints2D); //sw : South-West corner (Bottom-Left) //ne : North-East corner (Top-Right)
There is also a new form in the demo , showing the usage of the new procedure.

Hi Lema, great component, thank you for the work.
Can i ask you afew question?
1) How can i pan to show all the items on the map? I believe panto polyline do that but only pan to the latest point. I test on your sampel and do the same. by Example if the zoom selected put some point soff the view and apply
UniGMap1.PanToPolyline(1);
It only pans to the last point of the polyline, Same for a polygon, Theres no way to show all the points in the map autoadjusting the zoom?
2) AddmarkerEX do nothing here, cant find why.
Best regards.
Hello,
1. You can use the procedure fitBounds (this has been implemented in the latest version 1.4.7).
2. Check the existence of the file markerwithlabel_packed.js. It must be located into /files directory.

Mohammad, thanks for sharing !

Good Night, I'm trying to make UnigMap work to get the location. I did exactly as in the DEMO example, however Firefox has the following error "ReferenceError: GeolocationAPIForm is not defined", and I can not figure out what is missing. Because in the DEMO being compiled in my machine it works perfectly, however in my APP it does not work appearing the informed message.Can anyone help me if I can?
Do you create the GeolocationAPIForm as a Free or as Application Form?
How do you call the GeolocationAPIForm ?
Can you provide a working example ?

Hello! The problem only occurs only when I use bookmark with label of type TMarkerEX, when replaced by TMarker, the problem does not appear.
Hello.
Please check that you have latest markerwithlabel_packed.js in the corresponding /files directory.
(You can find this library in the uniGMap package)

Hello lema, how can I print and export to PDF the map?
Hello,
I tried before -without much success- to print a map with all its content.
The Google Maps Javascript API doesn’t print overlays (markers, lines, etc.) and the alternative solution with the use of Static Maps API didn’t work well because the URL I was building, exceeded the max limit (I think it was 2KB).
When I find some time, I will take a look at it again.
In the meanwhile, I suggest to look for workarounds like html2canvas or dom-to-image.

When an application has a login form the component is not showing the map. If it does not have the form of login dai it works ..
