dojox/mobile/EdgeToEdgeStoreList

This widget provides a list whose content is determined from a Dojo Store.

We can dynamically set the Store used by the list using the setStore() method.

This widget has a property called "itemMap" which appears to be quite unusual from a

Dojo/JavaScript perspective. It is an Object with the property names being properties in the Store

and the values of those properties being the properties on a ListItem that we wish to set.

For example, we see that ListItem has a property called "label" used to set the label of list

item. If we wish to have the Store data property called "companyName" be the value of the label

in a list item, we would declare:

itemMap: {

companyName: "label"

};

This is potentially confusing to many Dojo users as we are more used to structures which set the

property we wish to set to the value. For example:

itemMap: {

label: "companyName"

};

One interesting thing to note is that the itemMap is not constrained to supply data properties for

display. We can also use it to set arbitrary properties on a list item. For example, to register a

function to be called when a list item is clicked, we can declare:

itemMap: {

dataItemClick: "onClick"

}

Then it is assumed that the data of the store will contain a property called "dataItemOnClick"

which will be a function which will be invoked when the list item is clicked.
