I'm making a marker for a google map in primefaces and I'd like to set the icon. But the constructor for marker that allows setting the icon requires a parameter called "data". I'm not finding data being documented anywhere although one place I found says that it gets passed to super(). I can work around this by using a different constructor and then making a call to setIcon but that's two steps instead of one. So, any idea of what data is and how to safely make the call to the constructor that sets the icon?

I'm trying to draw polygon on my map using ngmap. The map is displayed correctly as this example is showing, but when I finish the draw, this is what I'm getting:
ng-map.min.js:25 Uncaught TypeError: Cannot read property 'onMapOverlayCompleted' of undefined
I used the same code of the example.
My questions:
1- How can I solve this error?
2- If I want to let the user draw only polygon form, I have tried to set the value of drawingMode to "polygon" but I'm always having the other draw options (circle...). How can let only the polygon draw?
3- How can I let the user clear the drawn polygon?
4- Is it possible to detect the action of putting (drawing) every points. I mean that to draw a line in the polygon for example I need at least two points. Can I detect when the user draw the first point then the second and get its coordinates?
Edit
This is the whole error that I see when I include ng-map.js instead of ng-map.min.js :
Uncaught TypeError: Cannot read property 'onMapOverlayCompleted' of undefined

I solved the first question:
My problem was that I'm using routes in the app.js. So the html and the controller are linked in it. To solve the problem, I put $scope.onMapOverlayCompleted instead of
var vm = this;
vm.onMapOverlayCompleted because I don't write the the ng-controller="DrawingManagerCtrl as vm" in my HTML. Then in the HTML I put on-overlaycomplete="onMapOverlayCompleted()" and it works.
I solved also the second question by using:
drawing-control-options="{position: 'TOP_CENTER',drawingModes:['polygon']}"
I'm want now to solve the other problems.
Any help please?

As the example you referenced shows, the overlaycomplete callback function receives e (Event) as the first parameter. This OverlayCompleteEvent object contains reference to the drawn overlay at Event.overlay (see docs of the original Google Maps JS API more info, since ng-map is only wrapper of the original API after all, specifically "OverlayCompleteEvent object specification" section).
Using that you can get the reference to the created overlay, store it and then later call .setMap(null) on it to delete it from map. E.g:
$scope.myDrawnOverlays = []; //array where you store drawn overlays
$scope.onMapOverlayCompleted(e){
...
myDrawnOverlays.push(e.overlay); //store reference to the drawn overlay after it's drawn
}
$scope.deleteAllDrawnOverlays(){
for(var i = 0; i < myDrawnOverlays.length; i++){
myDrawnOverlays[i].setMap(null); //remove overlays from map one by one
}
myDrawnOverlays = [];
}
Then whenever you want to delete all overlays, just call the function $scope.deleteAllDrawnOverlays (you can tie it to some button using ng-click or do whatever you want with it).

This is NOT possible using google.maps.drawing.DrawingManager which is used in your example. The reason is that DrawingManager doesn't support events for clicking at the map while drawing (see docs again for possible events, section "DrawingManager class").
So except hacky workarounds which could break any time with new api release, the only possible solution is to implement drawing of polygon yourself and not use DrawingManager. Check for example this SO answer, specifically the referenced example (right-clicks on map). They don't use ng-map, but basically what would you have to do is to add on-click="mapClickHandler" to your ng-map, in the mapClickHandler get position where you clicked on map, draw Marker there which would look like a dot and if you have more dots connect them with lines.
This is however too much for one question, you would have to probably read up on ng-map and relevant sections of Google Maps Js Api yourself.
I am new to Lua scripting, and game development. So please I am just a noob in Lua.
I have searched the net for solutions to my problems, without any luck.
I use Photoshop, Corona, Dusk, json and Tiled on windows7.
I am creating a "board" like game, i.e. Setlers. I am using a world map, as the background. The background image of the game area is a world map (world.png file). I have no problem here.
I would like to create transparrent clickable objects matching the countrys borders on my gamemap with all parameters and values (I have added in Tiled) stored in the object. So When the player clicks on the country the transparrent object (on top of the map) is the one clicked and an eventlistener acts on the click.
In Tiled I can create all the objects I need, naming them + assigning parameters and other values.
If I add object.alpha value in Tiled, the alpha value is passed on to corona and working there.
How can I read these data from the json/tmx file in Corona and adding them to a lua table?
The way I am thinking to use the Tiled map and its objects, is to create one polyline trace of each country’s border (creating one object per country). Then place each “country traced object” on top of the world.png map, also naming the object with the countrys name like “object.name = TileBritannia” and also the other properties for use in game.
My problem is getting the objects info, like object.name, and an eventlistener reacting to a click on the object.
Is a polyline the right way to create a clickable area on a map, when I use a png file as a background image?
What is the best way to create a country border objects, in one layer or with all countries as individual object layers in Tiled.
Can I create one layer with sub objects and still access them in my code?
How do I get the object name and other properties, set in Tiled.
When I try to use the (local britannia = tiledMap:load("britannia.json")) the "load" is not working, getting a nil value.
I am looking for a code that will extract/get/read the object.name i.e. “objBritannia” or "TileBritannia". from the json/tmx file.
When I try to read the different parameters from the json file, I don't get the result I expect. I get the result = function: 046A73B0, was hoping for an object name of some sort.
Please provide links to or code example.
I have edited the question.
Thanks
For questions 1 and 2: I have not used Tiled, but based on Corona Tiled, you have the right strategy in mind. That page makes me think that you can just use tap event listener to detect tap. If you are having issues with the example on that web page, please update your question to be more specific. If tap event handling doesn't work (maybe you're talking about a different Tiled lib), look a Polygon fill and Point in Polygon detection, because that's basically what you need to do. Try some stuff from there. If it still doesn't work for you, then update your question with specifics otherwise it will be likely get closed (it is a little too broad as it is).
For #3, Lua is a dynamic language that supports adding properties to objects in one line. So upon the example on the Corona Tiled page, all you would have to do is
tiledMap = require("tiled")
local britannia = tiledMap:load("britannia.json")
britannia.name = "Britannnia"
local Zulu = tiledMap:load("zulu.json")
zulu.name = "zulu"
Naturally you will probably have a whole bunch so you will create a function that you call for each tile. It's not clear what map.layer["objBritannia "].nameIs("TileBritannia") is supposed to do so I can't comment.
I am developing an Windows Forms application using VB.NET that offers the user to lookup addresses on Google Maps through a Web Browser. I can also successfully show the directions between two points to the user, as well as allow the user to drag the route as he/she pleases. My question now is - is it possible for me to get the lattitude/longitude information of the route, i.e. the overview_polyline array of encoded lattitude/longitude points and save it to e.g. a text file on my computer? Or is it possible to get a list of all the addresses located both sides of the route over the entire length of the route, and then save the data to a file on my computer? I'm using HTML files to access and display the Google Maps data in the Web Browser item.
Thank you
This is actually pretty simple if your just looking for the screen coordinates.
// this probably should be in your form initialization
this.MouseClick += new MouseEventHandler(MouseClickEvent);
void MouseClickEvent(object sender, MouseEventArgs e)
{
// do whatever you need with e.Location
}
if your strictly looking for the point in the browser, you need to consider the functions
browser.PointToClient();
browser.PointToScreen();
So, this method is usable if you know exactly where your form is (easy to get its coords) and where you webbrowser control is (easy to get coords of this as well since it's just a control in your form) and then, as long as you know how many pixels from the left or right, and from the top or bottom the image will be displayed, once you get the global mouse click coords (which is easy) you can predict where it was clicked on the image.
Alternatively, there are some scarier or uglier ways to do it here...
You can use the ObjectForScripting property to embed code to do this in the webbrowser. It's ugly to say the least. MSDN has some documentation on the process here: http://msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser.objectforscripting.aspx
Because its really ugly, maybe a better solution is to use AxWebBrowser - it's ugly too but not so scary.
In addition, I found this post of someone wanting to do it on a pdf document, and a MSFT person saying its not possible, but really what he is trying to say is that it isn't built in, even with a pdf document its still possible to predict with high to certain accuracy where it was clicked if you use the first method i described. Here is the post anyway: http://social.msdn.microsoft.com/Forums/en/csharpgeneral/thread/2c41b74a-d140-4533-9009-9fcb382dcb60
However, it is possible, and there are a few ways to do it, so don't get scared from that last link I gave ya.
Also, this post may help if you want to do it in javascript:
http://www.devx.com/tips/Tip/29285
Basically, you can add an attribute on the image through methods available in the webbrowser control, you can add something like onclick="GetCoords();" so when it is clicked, the JavaScript function will get the coords, and then you can use javascript to place the values in a hidden input field (input type="hidden") which you can add through the webbrowser control, or if there is one already on the page, you can use that. So, once you place the coords using javacript into that input field, you can easily grab the value in that using the webbrowser control, eg:
webbrowser1.document.getElementById("myHiddenInputField").value
That will get the value in that field, which you've set through JavaScript. Also, the "GetCoords()" function i mentioned is called SetValues() in the javascript method link i provided above (in the devx.com site) but I named it GetCoords because it makes more sense and didn't want to confuse you with the actual name they used, you can change this to any name you want of course. Here is the javascript they were using, this only gets the coords into a variable, doesn't put it into a hidden input field, we will need to do that in addition (at the end of the javascript SetValues/GetCoords function).
function SetValues()
{
var s = 'X=' + window.event.clientX + ' Y=' + window.event.clientY ;
document.getElementById('divCoord').innerText = s;
}
These guys are just saving it inside a div element, which is visible to users, but you can make the div invisible if you want to use a div field, there is no advantage or disadvantage in doing that, you would just need to set the visible property to false using javascript or css, but still, it is easier to use a hidden input field so you don't need to mess with any of that.
Let me know how you get along.
A similar question was already asked, but does not have a satisfying answer.
I want to change the CSS style for the map type selection buttons (which are actually DIVs that don't have a CSS class). The links in the referenced question show how to subclass controls, but the examples don't seem to work for GMapTypeControl. Tried the following
function CustomGMapTypeControl() {}
CustomGMapTypeControl.prototype = new GMapTypeControl()
CustomGMapTypeControl.prototype.setButtonStyle_ = function(button) {
button.style.backgroundColor = "red";
}
but the setButtonStyle_ function doesn't even get called.
Any solutions for this?
From the above code, I can say that you don't fully understand how to create a custom map control. There are 2 steps:
subclassing GControl
provide initialize() and getDefaultPosition() method.
Well, the initialize method is the place you create and style your control dom elements, and this method must return that dom element back. The getDefaultPosition() method indicates where this control should be placed (top-right,...), and it must return an object of type GControlPosition.
You must provide enough information so that when you call map.addControl(new CustomGMapTypeControl()) so that the map object could invoke and do the right things.
NOTE: All map controls should be added to the map container which can be accessed with GMap2's getContainer() method.
You can play around with http://code.google.com/apis/maps/documentation/javascript/v2/examples/control-custom.html when you want to create your own custom control with firebug.
I've got a plain-vanilla google maps widget sitting in a page and I'd like it if the driving directions opened up in a new window instead of taking over the current window. Is there a setting for this?
The driving directions go into whatever HTML element you specify as the second argument when you construct the GDirections object. So I guess that means you'd have to create the window before you create the GDirections object, which is likely not what you want.
The other thing that jumps out, looking at the documentation, is that you can call the load() method with the option getSteps = true. It's not clear what the "steps" data looks like, but I assume it essentially comes back as an HTML string. (Actually, it's not even clear how you get the data in the first place, but I assume it's GDirections.getSteps() or something similar.) So then when the "load" event happens, you can create the new window then put the "steps" data in it.
