Overview

1. widget service API

Tizen supports various kinds of APIs set for retrieving information of widgets. Every widgets are installed via package manager utilities. The information of installed widgets are stored in the system DB. In some cases, application developer needs to send update request to some widgets. To make it possible, this module provides related API set. But the API will only works if the widget and application are packaged in one.

1.1 APIs for retrieving information of widgets

To get the information for installed widgets.

1.2 APIs for communicating with running widget instances

To trigger the update event or send the updated content string to the widget.

2. Size of widget

Widget has predefined size types. 1x1 is a square so its pixel size of width and height must has to be same. 2x2, 4x4 also square. 2x1, 4x1, 4x2, 4x3 is a rectangle. so its pixel size of width & height should not be same. pixel size of width should be long than height. Pixel size can be differ between different devices. It depends on its screen resolution. So widget developer should care various kinds of devices (has different screen resolution).

Size Type	Size in pixels	Supported profile
WIDGET_SIZE_TYPE_1x1	- (SQUARE, depends on screen resolution)	No profile - This size type is not used. just defined for specifying a default cell size
WIDGET_SIZE_TYPE_2x1	- (RECTANGLE, depends on screen resolution)	Mobile
WIDGET_SIZE_TYPE_2x2	- (SQUARE, depends on screen resolution)	Mobile, Wearable (Default size)
WIDGET_SIZE_TYPE_4x1	- (RECTANGLE, depends on screen resolution)	Mobile
WIDGET_SIZE_TYPE_4x2	- (RECTANGLE, depends on screen resolution)	Mobile
WIDGET_SIZE_TYPE_4x3	- (RECTANGLE, depends on screen resolution)	Mobile
WIDGET_SIZE_TYPE_4x4	- (SQUARE, depends on screen resolution)	Mobile

Widget also works for Easy Mode. For the Easy Mode, there are different size types. Called WIDGET_SIZE_TYPE_EASY_NxM

Size Type	Size in pixels	Supported profile
WIDGET_SIZE_TYPE_EASY_1x1	- (SQUARE, depends on screen resolution)	Mobile
WIDGET_SIZE_TYPE_EASY_3x1	- (RECTANGLE, depends on screen resolution)	Mobile
WIDGET_SIZE_TYPE_EASY_3x3	- (SQUARE - depends on screen resolution)	Mobile

However the Easy Mode is not a mandatory requirements for viewer application development. So you will not be able to create your widgets using Easy Mode size types. But if you are developing the homescreen(or application which is related with widgets displaying), You should care these types too.
