Dashboards

1. Dashboard

The main responsibility of the Dashboard is to hold references to different widgets.

Widgets	Specifies what Widgets this dashboard should contain.	`<Widgets> <!-- Widget definitions --> </Widgets>`

Locked

Whether the dashboard should be locked or not. A locked dashboard can not be customized. Valid values true or false.

<Locked>true</Locked>

DisableCustomization

Dashboard customization can be disabled for dashboard. Valid values true or false. Default is false

<DisableCustomization>true</DisableCustomization>

Floating

<Floating>true</Floating>

ResizableHandles

Configure different options i.e any combination of comma seperated valid value, to enable resize widget from different positions like right, left, bottom, left bottom or right bottom. Valid values are e, se, s, sw, w. Default value is se.

e - Right
w - Left
s - Bottom
se - Bottom-Right
sw - Bottom-Left

<ResizableHandles>e, se, s, sw, w</ResizableHandles>

Widgets

Specifies what Widgets this dashboard should contain.

<Widgets>
    <!-- Widget definitions -->
</Widgets>

1.2. Dashboard Customization

A user can customize a dashboard by changing size and position of widgets.

Customization is enabled by default but can be turned off with a property:

tvc.helium.dashboard.customization.enabled=false

or by configuring a dashboard or widget as locked.

Customization actions

For customizable dashboards, a small UI element is automatically appended on the right hand side*, and it slides in to expand when the user focuses on the element. From this menu, the end user can create and manage multiple dashboard views via a sidepanel and easily reset any customization they have done on that particular dashboard view, or re-add a previously removed widget.

Resetting of end user widget which was added dynamically with reset dashboard customization can be enabled with a property:

tvc.helium.dashboard.customization.resetEnduserWidget=true.

Figure 2. Customizable Dashboard, showing the customizations menu

(*) If the dashboard is presented in stacked mode, for instance if the user is on a mobile device in portrait mode, the menu is hidden. Customizations only apply to normal dashboard mode.

Dashboard Views

The end user can create and manage multiple dashboard views within a single dashboard, allowing the user to create customized dashboards to better fit their workflow.

From the dashboard menu, the end user can open a sidepanel where it is possible to create and manage multiple dashboard views and easily copy, delete or reset any customization they have done on a dashboard view.

Customization maximum cap

If there are performance concerns, the max size of the customizations object can be controlled by the property:

tvc.core.customization.maxContentSize

default value: 100000 Characters

1.2.1. Widget

The <Widget> element references widget instance via the ref attribute. For example <Widget ref="tvc:widget:helium/MaterialCategoryWidget.xml"/>

It also specifies where an widget should be rendered on the dashboard and what size the widget should have.

For sizes and placements of widgets, keep in mind that TVC Helium is based on a so called grid system, where a dashboard is generally divided into 12 columns. A Widget that should cover the entire browser window width should therefore specify its width to 12, two widgets side-by-side should each specify 6, and so on.

The <Widget> element supports the following child elements.

Name Description Example

The identifier of the widget. Should be unique.

At the moment there is no uniqueness check for widget ID’s. Multiple widgets with the same Id can cause unexpected behaviour.

<Id>materialcategory</Id>

Locked

Whether the widget should be locked or not. A locked widget can not be customized. Valid values true or false.

<Locked>true</Locked>

Width

The width of the widget. Valid value: Positive integer between 1 and 12. It supports the following attributes:

minWidth: Specifies minimum width upto which Widget size can be shrink.
maxWidth: Specifies maximum width upto which Widget size can be expand.

These attributes are optional.

<Width>3</Width>

<Width minWidth="3">6</Width>

<Width maxWidth="8">6</Width>

<Width minWidth="3" maxWidth="8">6</Width>

Height

The height of the widget. Valid value: Positive integer. It supports the following attributes:

adjustHeight: Specifies whether the widget should adjust the height to fit the content (and vertical toolbar if defined) or fill the available space when there is single widget.Valid values are :

true - Widget should adjust the height to fit the content

false - Widget should not adjust the height to fit the content

fill - Fill the available space for a single widget..

The widget needs to have a default height even if adjustHeight is set to true.

Manual Expand/Shrink of Widget will not work when adjustHeight is set to true.

minHeight: Specifies minimum height upto which Widget size can be shrink. This can be set globally in tvc.properties tvc.helium.dashboard.widget.defaultMinHeight = 5. Default value is 5.
maxHeight: Specifies maximum height upto which Widget size can be expand. This can be set globally in tvc.properties tvc.helium.dashboard.widget.defaultMaxHeight = 15. Default value is 18.

minHeight and maxHeight attributes are optional.

<Height adjustHeight="true">
    4
</Height>

<Height minHeight="3">6</Height>

<Height maxHeight="8">6</Height>

<Height minHeight="3" maxHeight="8">6</Height>

<Height adjustHeight="fill"></Height>

Specifies where on the X axis the widget should be placed. Valid value: Positive integer.

<X>0</X>

Specifies where on the Y axis the widget should be placed. Valid value: Positive integer.

<Y>1</Y>

Template

Specifies which template the widget should be rendered with. If omitted a default template will be used. Useful if you would like to design your own widget frame template with full path from project root, or render a widget without a header. The latter is accomplished by setting the element text to headerless. Default directory path used for searching template is helium\templates\widget.

<Template>
    headerless
</Template>

<Template>helium/custom/templates/headerless</Template>

Badge

This element is used to render a small badge in widget header on right side of the widget title that shows total object count in the widget. In case of history widget it shows number of rows. Valid value is true or false. Default value is false.

<Badge>true</Badge>

<?xml version="1.0" encoding="UTF-8"?>
<Dashboard xmlns="http://technia.com/helium/Dashboard">
    <Locked>false</Locked>
    <Floating>true</Floating>
    <Widgets>
        <Widget id="dt1" width="6" height="10" x="0" y="0" locked="false"
            badge="true" ref="tvc:widget:helium/TableWidget.xml" />

        <Widget ref="tvc:widget:helium/MaterialCategoryWidget.xml">

            <Id>state</Id>
            <Width minWidth="2" maxWidth="5">3</Width>
            <Height minHeight="3" maxHeight="7">5</Height>
            <X>6</X>
            <Y>5</Y>
        </Widget>

        <Widget ref="tvc:widget:helium/RevisionDonutWidget.xml">
            <Id>revision-donut</Id>
            <Width>3</Width>
            <Height>5</Height>
            <X>9</X>
            <Y>5</Y>
        </Widget>
    </Widgets>
</Dashboard>

Just like for dashboards, an end user can do certain customizations on widget level. Exact customizations available will depend on the type of widget. For example, in a Table widget the end user can customize the pagination size, column visibilities, etc.

Customization on widget level is enabled by default, for dashboards where customization is enabled.

Customization actions

For the normal widget template, a Reset icon is available in the widget header. The user can reset widget level customizations from there. If you use your custom widget template, you can still use the JavaScript API .resetCustomizations(). After deleting a widget customization, the widget will refresh.

Figure 3. Resetting widget customizations

1.5. Open in Sidepanel

JavaScript API, App.page.sidepanel.openDashboard() can be used to open a dashboard in page’s sidepanel, e.g. App.page.sidepanel.openDashboard("tvc:dashboard:hex:engineering/PartInfoSidePanel.xml", "1.2.3.4");

This could be used for e.g. to quickly see contextual information about an object without navigating back and forth.

Figure 4. Dashboard in Sidepanel

JavaScript API, .updateWidgets() is added to Dashboard instance. This API can be used to reload related widgets within the dashboard with different context ids. If the widget is initially hidden, it’ll be made visible.

You need to have access to the dashboard instance to invoke this method. If you instead have access to Widget instance, see this

For an implementation example, refer PartDetailActions.xml Column and Menu definitions available as part of HEX distribution.

1.7. Widget lock unlock icon

The lock unlock icons can be configured for two different scenarios as given below:

Widget lock and unlock icon reflecting the action available to user. For ex :

If widget is locked it would show unlock icon.
If widget is unlocked it would show lock icon.

This is the default behaviour.

Widget lock and unlock icon reflecting the current state of widget.For ex :

If widget is locked, show lock icon.
If widget is unlocked, show unlock icon.

This can be enabled globally as init param tvc.helium.widget.lock.showAlternateIcon = true
