== Widgets
include::../variables.adoc[]
#TODO#
Widgets are the most customizable UI components in QQQ.
They can be used either on App Home Screens (e.g., as Dashboard screens),
or they can be included into Record View screens.
QQQ defines several types of widgets, such as charts (pie, bar, line),
numeric displays, application-populated tables, or even fully custom HTML.
=== QWidgetMetaData
A Widget is defined in a QQQ Instance in a `*QWidgetMetaData*` object.
#TODO#
*QWidgetMetaData Properties:*
* `name` - *String, Required* - Unique name for the widget within the QQQ Instance.
* `type` - *String, Required* - Specifies the UI & data type for the widget.
* `label` - *String* - User-facing header or title for a widget.
* `tooltip` - *String* - Text contents to be placed in a tooltip associated with the widget's label in the UI.
** Values should come from the `WidgetType` enum's `getType()` method (e.g., `WidgetType.BAR_CHART.getType()`)
* `gridColumns` - *Integer* - for a desktop-sized screen, in a 12-based grid,
how many columns the widget should consume.
* `codeReference` - *QCodeReference, Required* - Reference to the custom code,
a subclass of `AbstractWidgetRenderer`, which is responsible for loading data to render the widget.
* `footerHTML` - *String* - HTML String, which, if present, will be displayed in the
footer of the widget (not supported by all widget types).
* `isCard` - *boolean, default false* #TODO#
* `showReloadButton` - *boolean, default true* #TODO#
* `showExportButton` - *boolean, default false* #TODO#
* `dropdowns` - #TODO#
* `storeDropdownSelections` - *boolean* #TODO#
* `icons` - *Map<String, QIcon>* #TODO#
* `defaultValues` - *Map<String, Serializable>* #TODO#
#TODO#
There are also some subclasses of `QWidgetMetaData`, for some specific widget types:
*ParentWidgetMetaData Properties:*
* `title` - *String* #TODO - how does this differ from label?#
* `childWidgetNameList` - *List<String>, Required*
* `childProcessNameList` - *List<String>* #TODO appears unused - check, and delete#
* `laytoutType` - *enum of GRID or TABS, default GRID*
*QNoCodeWidgetMetaData Properties:*
* `values` - *List<AbstractWidgetValueSource>* #TODO#
* `outputs` - *List<AbstractWidgetOutput>* #TODO#
