create new marker on map widget
Hi, I am trying to use the new Map Widget in Livecode Indy 9.0.0. I would like to create a new marker on the map when the user clicks on the map widget for a second (mousedown without moving the mouse). The widget seems not to create any mousedown message, so I thought I need to have an invisible button on top of the map widget, but then I loose the native map navigation (scroll, zoom etc.). Any hints how to solve this? Thanks. Oliver
Re: create new marker on map widget
Hi, I perhaps found a workable solution, see the atttached stack. I placed an invisible button on top of the map widget with follwoing code:
Do you think this is the way to go or are there easier solutions? Thanks. Oliver
Code: Select all
on mousedown
local repeatcounter
put the mouseloc into tempmouseloc
repeat while the mouse is down
wait 2 ticks
if the mouseloc is not tempmouseloc then pass mousedown
put repeatcounter+1 into repeatcounter
if repeatcounter > 10 then
set the rect of me to the rect of widget "utopia"
put the left of me into xmini
put the width of me into xmaxi
put the top of me into ymini
put the height of me into ymaxi
put the region of widget "utopia" into tempregion
set the itemDelimiter to comma
put item 1 of tempregion into latcenter
put item 2 of tempregion into loncenter
put item 3 of tempregion into latspan
put item 4 of tempregion into lonspan
put latcenter + latspan/2 into latmini
put loncenter - lonspan/2 into lonmini
put latcenter - latspan/2 into latmaxi
put loncenter + lonspan/2 into lonmaxi
put latmaxi-latmini into latdiff
put lonmaxi-lonmini into londiff
put the mouseh into xposition
put the mousev into yposition
put (latmini+(yposition-ymini)/ymaxi*latdiff) into currentlat
put (lonmini+(xposition-xmini)/xmaxi*londiff) into currentlon
ask "name of the marker"
if the result is "Cancel" then exit mousedown
put the markers of widget "utopia" into tMarkers
put currentlat & comma & currentlon into tMarkers [it]["coordinates"]
put it into tMarkers[it]["title"]
set the markers of widget "utopia" to tMarkers
exit repeat
end if
end repeat
end mousedown

Re: create new marker on map widget
Thank you for the information on the map widget, OKK. Does anyone know how to have the map go to the My location when the map opens? I know I can set the showsUserLocation, but how do I have the map go to the location of the user when the map opens. I can't seem to find that parameter. Thanks!

Re: create new marker on map widget
Hi Matt,
I could not find a way to center the map around the user position using just the properties of the map widget. A work-around could be to read the current location from the gps sensor and then set the region of your map widget with current readings of latitude and longitude as centre coordinates. Look "mobileCurrentLocation" in the dictionary if you are not familiar with gps tracking.

Re: create new marker on map widget
Btw. my method posted above works fine on MacOS and iOS standalones, but I could not get it working on Android devices. So any help with this issue in regards to Android deployment is highly welcome.

Hi Oliver,
did you read the last paragraph of this page "Deploying on Android":
https://livecode.com/docs/9-0-0/components/map-widget/
Looks like you need to supply an Google Maps API key!

Re: create new marker on map widget
Hi Klaus, I have the google API keys entered in the inclusions tab of the standalone settings. I get the map widget itself working, but I can't fetch the extended mousedown message which should trigger the creation of a new marker. It works on desktop but not on the device. The script I posted is located in an invisible button above the map-widget. It seems that in the android standalone this invisible button is placed below the map-widget and I can't fetch any mousedown message.

Re: create new marker on map widget
Hi all, my original issue is still unresolved, according to Panos answer to my bug report https://quality.livecode.com/show_bug.cgi?id=21584 the Android behaviour is actually the one that is correct. That means, my work-around is likely not to be working in future updates. Therefore I would like to repeat my original question: Does anyone of you have a suggestion how can a user of my app create a new map marker by clicking and holding on the map widget ?
Thanks for any hints!

Re: create new marker on map widget
Can anyone please confirm the map widget to be working on Android, by using livecode latest stable release? It meets my requirements well for the ios but shows an empty map on simulator and Samsung Galaxy Note8. Initially the app would crash without the valid/correct google API keys (used Map API not the other keys to resolve it). Now the app is stable but no maps on drawn in the map widget?
Thanks for all the help in advance.

Hi Torsten,
glad that the workaround was useful. Do you have any ideas on how to get this functionality working on mobile? Best. Oliver
