How does the widget config of a widget column work?


Asked by Taylor Ware on Dec 14, 2021 FAQ



The widget config of a Widget Column is used to create multiple instances of the Widget. Based on the xtype contained in the widget config, the Widget Column will create an object that is either derived from Ext.Widget or from Ext.Component. This config cannot be an instance already because Widget Column needs one instance per rendered cell.
Indeed,
As it turns out, grid is always going to put our widgets in new rows unless we specify otherwise. There's a pretty good reason for this, which is that there are actually an infinite number of rows and columns. Even if we only configure two columns, we can actually put things in column 2, 5, or 67, with empty columns collapsing to zero width.
In fact, If you need to add the widget to the app first, click a widget placeholder on the Widget tab. In the Choose Widget window that opens, select the widget and click OK. The configuration window for this widget appears with a list of layers associated with the map. By default, all supported layers are listed in the table.
Consequently,
The user interface for a Widget is defined by a broadcast receiver. This receiver inflates its layout into an object of type RemoteViews. This object is delivered to Android, which hands it over the home screen application.
In addition,
A widget gets its data on a periodic timetable. There are two methods to update a widget, one is based on an XML configuration file and the other is based on the Android AlarmManager service. In the widget configuration file you can specify a fixed update interval.
