US 2016/0110055 A1 · EVENT-BASED ARCHITECTURE FOR EXPAND-COLLAPSE OPERATIONS

Abstract

Techniques are disclosed for event-based architectures for implementing expand-collapse input-output operations in user interfaces. Certain techniques are disclosed herein that allow for a expand and/or collapse functionality via passing asynchronous events to a datasource module, which may or may not be routed through a view module. The datasource module determines what data is to be shown or hidden and issues an insert/delete event back to the view module. The insert/delete event may include additional data to be inserted into the user interface, and may include an identifier of where, within the displayed user interface, data is to be inserted or deleted. A view module may be configured to receive insert or delete events, and, in response, cause the user interface to be modified based upon the event. The view module may perform these updates by inserting or removing Document Object Model (DOM) nodes from a DOM associated with the user interface.

Dependent claims

A method, comprising:

presenting, to a user via a display of a computing device, a view comprising one or more nodes and an affordance associated with a first node of the one or more nodes, wherein the affordance is in an expand state, and wherein the view is generated by an application executing at the computing device;
receiving, at an input-output interface of the computing device from the user, a first user input indicating a selection of the affordance;
and
responsive to the first user input:
retrieving, by a datasource module of the application from a data store, additional data to be displayed by the view, wherein the additional data is associated with the node;
generating, by the datasource module, an insert event indicating that the additional data is to be displayed by the view;
detecting, by a view module of the application, the insert event;
and
updating, by the view module, the view to display the additional data in response to the detecting the insert event.

6 more elements

A non-transitory computer readable storage medium storing instructions which, when executed by one or more processors of a computing device, cause the computing device to perform operations comprising:

presenting, to a user via a display of the computing device, a view comprising one or more nodes and an affordance associated with a first node of the one or more nodes, wherein the affordance is in an expand state, and wherein the view is generated by an application executing at the computing device;
receiving, at the computing device from the user, a first user input indicating a selection of the affordance;
and
responsive to the first user input:
retrieving, by a datasource module of the application from a data store, additional data to be displayed by the view, wherein the additional data is associated with the node;
generating, by the datasource module, an insert event indicating that the additional data is to be displayed by the view;
detecting, by a view module of the application, the insert event;
and
updating, by the view module, the view to display the additional data in response to the detecting the insert event.

6 more elements

An computing device, comprising:

one or more processors;
one or more network interfaces communicatively coupled with the one or more processors;
and
a non-transitory computer readable storage medium communicatively coupled with the one or more processors storing instructions which, when executed by the one or more processors, cause the computing device to perform operations comprising:
presenting, to a user via a display of the computing device, a view comprising one or more nodes and an affordance associated with a first node of the one or more nodes, wherein the affordance is in an expand state, and wherein the view is generated by an application executing at the computing device;
receiving, at the computing device from the user, a first user input indicating a selection of the affordance;
and
responsive to the first user input:
retrieving, by a datasource module of the application from a data store, additional data to be displayed by the view, wherein the additional data is associated with the node;
generating, by the datasource module, an insert event indicating that the additional data is to be displayed by the view;
detecting, by a view module of the application, the insert event;
and
updating, by the view module, the view to display the additional data in response to the detecting the insert event.
