Push messages in WAB widgets?

[KarstenRank]

Hi,

is it possible to create a costum widget, that shows push messages? For example if the webmap was changed, that the user reloads the webmap application? Or has someone other ideas?

Thanks,

Karsten

Sure it can   !

You'll need to create this in a theme though, this because widget's lifecyle ony start from the moment it has been openend.

Tip: have a look into Dojo Publish ...

Hi, what do you mean by webmap have changed? as in change in layers or change of basemap?

The ArGIS javascript API are largely event driven:
