Hello BJ
Thank you very much for the link.
I used to see the widgetName=new Widget
I understand that you are extending an existing tiddler, but I don't
understand this lines
var DropZoneWidget = require("$:/core/modules/widgets/dropzone.js")["dropzone"];
var Widget = require("$:/core/modules/widgets/widget.js").widget;
/*
If the dropzone widget has already required the widget.. Why are you requiring
it again?
*
overload the base widget class initialise
*/
DropZoneWidget.prototype.initialise = function(parseTreeNode,options) {
Widget.prototype.initialise.call(this,parseTreeNode,options);
this.addEventListeners([
{type: "tw-dropHandled", handler: "handleDropHandled"}]);
};
Why do you call the widget initialise? And why do you add the event handlers
here? I thought this is normal in the render function. I readed again the
dropzone code and It never raises a tw-dropHandled event. Where is that event
raised?
Thank you very much
