has anyone messed around with using the map widget offline?
i was in a hurricane zone, last week, and over the weekend. there was a
fair amount of offline time, when having maps loaded into my droid phone
would have been useful. the offline map apps that i can find have limited
zoom capability.



I use Sygic for offline maps on my Android phone.

Re: Map Widget - how does it actually work?

[Prothero-ELS via use-livecode]

Graham,
My demo stack was enhanced a lot by Hermann but I don’t know where it is, after 
a cursory search. He added a bunch of other capabilities, but I felt a quick 
look at the Google map docs would make it easy to add them. His expanded 
version may be in the examples repository. I didn’t check it.

My main problem was to calculate the bounding lat/lons of the displayed map.

Good luck with it.

Re: Map Widget - how does it actually work?

[Graham Samuel via use-livecode]

Bill, thanks for all this. I will study it today (it’s breakfast time in France 
as I write this).

I did some internet searching to look at the underlying Apple Map system - 
which is used for the LC version of the Map widget for iOS - and its API. It’s 
rich and complex, so the widget just scratches the surface of the available 
functionality, 

This saddened my a bit, but then I reflected on the enormous simplification 
that LC represents for a developer compared with what you’d have to learn and 
apply before getting anywhere at all coding a mobile app ‘outside’ LC. It 
really is quite alarming. I was a geek once, and learned and applied some very 
obscure languages within very primitive and obscure systems, but I have zero 
taste for that sort of thing now. As a further example, take a quick look at 
what Apple say to attract you to their Swift language. They want to tell you 
it’s easy and fun - I think one can have a contrary opinion, especially if one 
has never coded in Objective-C or anything like it. [That was a pro-LiveCode 
rant, in case you didn’t notice.]

Re: Map Widget - how does it actually work?

[Graham Samuel via use-livecode]

Thanks Alex - that’s solid gold! I might even be able to use the widget, though 
perhaps not for what I intended which was to draw a route consisting of a 
series of standard Lat-Lon coordinates, in other words a very large number of 
linked polylines. This is a tentative conclusion, so probably wrong.

This is the first time I’ve realised that the Guide you get when you click on 
‘Dictionary’ in the LC menu is different from the “User Guide” which you can 
access via the same menu. I haven’t got time to find out the differences, but I 
note that “Map Widget” appears in one and not the other. Or am I wrong? Try 
searching  the "LiveCode 9.6.0-rc-2 User Guide 5/19/20” and see what you get.

The manifest xml file for the map widget lists its license as 
"community", which seems wrong. However, *every* extension has a license 
of "community", which seems wronger still. I don't see any way to set 
that, so it must be an extension builder "feature".

Re: Map Widget - how does it actually work?

[Alex Tweedly via use-livecode]

Well, the big advantage of widgets is that you can look at the source 
code. As it says in the Livecode Lesson ( 
http://lessons.livecode.com/m/4071/l/1005132-how-do-i-modify-a-livecode-widget 
),


What do you do if a LiveCode widget is missing a property or message 
you need?


The source code for all the widgets provided 'out of the box' is 
accessible so you can take those widgets as a base and improve and

So, sadly, you can't just go look at the source code to find out what

However, in the dictionary under "Guide" you can find some more info / 
example about the map widget. In particular, it defines the format used 
for  region, coordinates, span and markers - which is probably all that 
you need (I think all the others parameters in the API are booleans).


Disclaimer: I have never used the map widget - everything I say here is 
taken at face value from the doc and the visible files within the widget 
folder of 9.6.0(rc1)

This will not work. I just tried:
The map widget updates in short intervals like a movie.
Even a native button disappears.
So the overlaying native object should also use a fast update like

http://forums.livecode.com/viewtopic.php?p=172789#p172789

which forces a fast update by playing a *non-existent movie.

Another possibility with the map widget itself is to make the custom
marker using polylines. (See property polylines of dictionary/map widget).

Polylines[i]["ccordinates"] are a simple list of coordinate points,
separated by comma (not by cr).
So one could try to exercise that with an ordinary polygon graphic over
a static map (an image).

Thanks Ali

I'm clearly "out of my depth" here… after looking at the Google Maps model. 

looking at:  com.google.android.gms.maps.model 

 I think see why you are talking about overlays, as these comprise  "model 
classes" 

GroundOverlay   A ground overlay is an image that is fixed to a map. 
GroundOverlayOptionsDefines options for a ground overlay.

So it does not seem like it is feasible for us to simply "drop in" a large 
vector diagram/map/illustration… 
unless perhaps there was some third party which could do, as you say, insert 
this as an overlay into map object, so that, instead of UK, we would have 
"Middle Earth"

Something to think about: if you get this far with the tech, pushing it just 
enough to allow a custom environment (assuming it meets some standards 
obviously) would be interesting

The default implementation on both platforms retrieves map images from

We would do whatever is feasible in a cross-platform way. Actually looking
at it now, there would be a similar thing on Android:
https://developers.google.com/android/reference/com/google/android/gms/maps/model/TileProvider

Brahma, it's my understanding that you *are* talking about overlays - or at
least using overlays is exactly how such things are achieved with a native
map object. You override a method that returns a particular image for the
currently visible tiles of the map, so that you don't have to have your
whole map image in memory all the time.

The default implementation on both platforms retrieves map images from
somewhere online

Markers are not 'in the message path' quite in the way you are suggesting -
at the moment the touch / click is received by the native view, resulting
in a callback that is handled in LCB, which posts an appropriate message
back to the widget's script object (in this case 'markerClicked pTag' where
pTag is the tag defined for that marker).

Re: Map Widget Futures

[Sannyasin Brahmanathaswami via use-livecode]

Thanks for replying Ali

I wasn't thinking of overlays, though that could be useful and would obviously 
be an early enhancment request.

message path:  Presumably "markers" are in the msg path… i.e. like buttons, and 
would respond to mouseup/down/touch. That would suffice for my V1 vision of use 
cases. Though I guess without overlays we are forced to abrupt changes on the 
screen if we want the map to be a portal to ther data…but… leave that for V2…


Today's question is not about overlays… the question is: "What is the map 
object?"

Where does it come from and can we supply some alt document… for example, if 
one had an artist create 

The WonderFul World of Ali, i.e. a fantasy map…in SynFig Studio… one could 
export to a vector format.

How do we make this the map "object"  Other more prosaic uses could be: complex 
diagrams that cover "hectares/square miles" of space… the map of Oxford 
University campus… Tolkein's Middle Earth etc. engineering diagram with various 
parts of some machine all laid out on one complex, very large "map"  -- giant 
SVG's. giant in the sense of being created on a canvas in your illustration 
software set to 4 feet by 4 feet… which then can export to vector… scale up or 
down, but at that size one can work in areas with a lot of detail… and create a 
"Villiage of Hobbits" off in the corner… 

Here for example is a very simple test SVG export from a small inexpensive 
program that I like called "Diagrammix"

http://dev.himalayanacademy.com/html/info/img/site-map.svg

so what comprises the map "object" and what is the scope of its format, 
properties etc. Obviously the developer has to source the map object from 
somewhere, in some format.

In the first instance the widget will support annotations/markers and
polylines, but won't support generic overlays.

be done natively then it can be done.

Just thinking aloud for a second, one way we could potentially make that
work, and make the map widget a lot more flexible on the objective-c side
is to allow custom implementations of the map delegate in LCB. This would
enable you to write the appropriate callbacks to do custom overlays. I
can't think of a particularly nice way to support overlays as a basic
property, but that might just be because I haven't thought about it enough.

Re: Map Widget"

[William Prothero via use-livecode]

Devin:
Looking at the dictionary, it only works on iOS. I need Mac and Windows 
platforms, and iOS is good, but limited. But, this external looks like it would 
do what I want, as it is described. It looks like it will take map data and 
make and image which I could then modify as I want.

Alas, no dice on the desktop. A cross platform Map widget that does this would 
be pretty useful.

 You could hypothetically export the image data from the HTML canvas 
 object, export the lat/lng boundaries, and present all of that through a

 Many of the map apis allow you to put both markers and polygons on a map

Re: Map Widget"

[Devin Asay via use-livecode]

Bill,

Have you checked the mergMK extension referred to in the post? To my knowledge 
the widget referred ton in the post has not yet been created.

To take another tack—have you looked at the Google Static Map API? If you’re 
comfortable using RESTful API’s in LiveCode you can get a pretty serviceable 
map display in your stack. The API just returns image data, so it’s pretty 
straightforward to display the map in an image object.

Re: Map Widget"

[Jonathan Lynch via use-livecode]

I use maps in the browser widget extensively for Augmented Earth. It works 
great.

You could hypothetically export the image data from the HTML canvas object, 
export the lat/lng boundaries, and present all of that through a LiveCode image 
object. Be prepared to do a bit of math, but I think it would work.

Many of the map apis allow you to put both markers and polygons on a map with 
JavaScript, which might give you better performance.

Re: Map Widget"

[William Prothero via use-livecode]

Folks:
On another aspect of this question, was a Map Widget, advertised on the site I 
linked to below, ever created?
https://livecode.com/map-widget-coming-to-livecode/

Re: Map Widget"

[William Prothero via use-livecode]

What I'm thinking about is a map that I can control location and magnification 
of a google map from livecode, do an image capture, and draw symbols on that 
capture. I would need to be able to recover the latitude and longitude of the 
displayed map boundaries.

I remember some discussions about whether image capture works with browser 
windows.

If anybody has wisdom on whether this will work, before I spend a bunch of time 
researching this, I'd be grateful. There is, I think, an API to google Earth, 
which might be something to look into.

Thanks,
Bill P

I do not believe you can have a google map not in a browser. That is to say, 
you cannot have a google INTERACTIVE map. You can certainly drop screenshots in 
as graphics.
