esri-webappbuilder-widget-eDraw

Ehanced draw widget for WebApp Builder for Arcgis.

Fork and modifications of the official widget draw for WebApp Builder for Arcgis : http://doc.arcgis.com/en/web-appbuilder/create-apps/widget-draw.htm

The widget use the proj4js library (https://github.com/proj4js/proj4js) for point's lat/lon measure (for non mercator maps) : https://github.com/proj4js/proj4js

Improvements:

• add name and description fields on drawings
• enable infowindow on drawings (selection)
• on text drawing, no insert if no name.
• on modification : enable geometry update (with snapping if wanted : CTRL) and preview symbology changes on the fly
• list
  • add list of all drawings
  • actions on each drawing : modify / delete / [up / down] / zoom
  • all drawings : zoom, copy, delete, export
  • on drawing infowindow -> select drawing in list
  • on zoom on a drawing -> select drawing on map (and show infoWindow)
  • re-order graphics with drag&drop
• import/export : allow users to export or import drawings (json format)
  • import can be done with file drag&drop in import popup
• localStorage
  • dynamic saving on each drawing add/delete/update
  • on widget load : load drawings saved in local Storage
• draws plus (initially from Larry Stout https://geonet.esri.com/people/Larry_Stout)
  • preview under mouse when adding text or point
  • for text, add font choice, font angle, bold, italic, placement and underline options.
  • add arrow menu for polyline
• checkbox to hide drawing's layer (and therefore widget UI)
• add of Nautical unit
• measure's for points/polylines/polygons with automatic update on element's update (or delete). Measure's can be individually disabled/enabled on any graphic.
• "On the fly" measure when drawing
• defaults symbols can be specified in config's file
• use of builtin projection engine (available since esri js api 3.24) instead of proj4js library

configuration :

• export file name.
• Confirm on delete. A confirm dialog when user delete drawing(s) ?
• add up/down buttons in list ? (N.B. : re-ordering can be done with drag&drop)
• Enable local storage. enable auto-saving in local storage and loading saved drawings on widget load.
  • Local storage key : let empty or set a name :
    • if empty, all apps with eDraw widgets share the same local storage (apps on the same server)
    • if not empty, all apps with the same key share the same local storage (apps on the same server)
• Choose availables font families in text plus
• (without UI) set default symbols
• enable measure by default ? (is measure checkbox checked on polygon/polyline/point add ?)
• measure's labels patterns
