Figure 1. Top Bar

The <TopBar> element supports the following child elements.

Name Description Example

ShowAppName

Whether the application name should be visible or not. Valid values: true or false (default).

If you would like to display image instead of name (e.g. company logo), see Using image as logo 
<ShowAppName>false</ShowAppName>

TooltipSettings

Optional settings as given in Semantic Popup Settings can be passed for tooltip.

Tooltip will only be shown when commands are configured with <Alt> 
<TooltipSettings>
  <![CDATA[{
    "variation": "inverted",
    "hoverable": "true",
    "position":"bottom center"
     }]]>
</TooltipSettings>

Left

Child elements to the <Left> element will be left aligned. See Menu/Commands section.

 
<Left>
    <!-- child elements -->
</Left>

Middle

Child elements that are aligned in the middle of the available remaining space between <Left> and <Right> sections. Currently this section can exclusively hold a <Search inline="true"> command, rendering an inline search field.

 
<Middle>
  <Search inline="true">tvc:search:hex:common/TopBarSearchV2.xml</Search>
</Middle>

Right

Child elements to the <Right> element will be right aligned. See the Menu/Commands section.

 
<Right>
    <!-- child elements -->
</Right>

ShowBreadcrumb

Whether the breadcrumb navigation should be visible or not. Valid values: true or false (default). See Breadcrumb section.

 
<ShowBreadcrumb>true</ShowBreadcrumb>

A breadcrumb trail on a page indicates the page’s position in the application hierarchy. A user can navigate all the way up in the application hierarchy, one level at a time, by starting from the last breadcrumb in the breadcrumb trail. It has maximum length of 5 elements.

For breadcrumb trail to work properly, pages need Title element.

It is a fixed container below topbar of the and is configurable with ShowBreadcrumb setting in TopBar.

Figure 2. Breadcrumb

It is responsive by design. Once breadcrumb container exceeds device display width, it will get collapsed and an ellipsis icon will be shown to left of breadcrumb. One can expand it again by clicking on ellipsis icon.

Mobile Breadcrumb

The <Left> and <Right> elements mentioned above can have the following child elements.

Depending on their parent element, they will either be left or right aligned in the TopBar

It is recommended to group commands in menus to avoid spill over of commands in topbar.
Name Description Example

Separator

Will render a horizontal separator

 
<Separator />

Menu

Will render a dropdown menu containing commands. The menu is defined in the xml referenced inside of the element.

 
<Menu>
    tvc:menu:helium/MyDashboards.xml
</Menu>

Command

Will render a command. The command is defined in the xml reference from inside of the element.

 
<Command>
    tvc:command:helium/ResetDashboards.xml
</Command>
Dynamic Menu

Normally, a menu holds a list of pre-configured commands and/ or menus. As opposed to this, a dynamically defined menu allows different content. A dynamic menu is still configured as a regular menu, but has some extra settings which when configured allows developer to get control when the menu is activated. This means, it’s also possible to have a dynamic menu that has a mix of predefined commands as well as dynamically added ones.

An example of such a menu is Recently Viewed objects.

Options
Name Description Required Example

dynamicmenu

Defines a menu as a dynamic menu

true

 
</Menu>
	<Setting name="dynamicmenu" value="true" />
</Menu>

href

Ajax endpoint to fetch JSON data for dynamic content

true

 
<Menu>
    <Setting name="href" value="tvc-action/heliumDataTable?config=tvc:tableconfig:helium/RecentlyViewed.xml&amp;reload=true&amp;bindKey=foo" />
</Menu>

id

Unique identifier for the dynamic menu. Can be used, for e.g. to get hold of the menu from JavaScript.

false

 
<Menu>
    <Setting name="id" value="recent-objects" />
</Menu>

template

Reference to Handlebars template to render content on client

false*

 
<Menu>
    <Setting name="template" value="helium/templates/recentobject/recentobjectcommand" />
</Menu>

onActivate

JavaScript callback to handle menu when activated. If defined, it’s this callbacks' responsibility to configure dynamic menu content.

onActivate and/ or template should be provided.

false*

 
<Menu>
    <Setting name="onActivate" value="App.RecentObjects.render" />
</Menu>

A JavaScript API, App.Topbar.dynamicMenus.getById(menuId) can be used to get access to the dynamic menu.

Dynamic menus are currently available only in Topbar.
Example
<Menu xmlns="http://technia.com/TVC/Menu" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://technia.com/TVC/Menu http://products.technia.com/tvc/schema/latest/Menu.xsd">
	<Label>recent.title</Label>
	<Setting name="dynamicmenu" value="true" />
	<Setting name="id" value="recent-objects" />
	<Setting name="template" value="helium/templates/recentobject/recentobjectcommand" />
	<Setting name="onClick" value="App.routing.open" />
	<Setting name="onActivate" value="App.RecentObjects.render" />
	<Setting name="href" value="tvc-action/heliumDataTable?config=tvc:tableconfig:helium:recentobject/RecentlyViewed.xml&amp;reload=true&amp;bindKey=foo" />
</Menu>
Recently Viewed objects

"Recently Viewed" objects is a built-in dynamic menu which when configured shows a list of objects that the user has recently visited. The built-in menu uses TableConfig for defining and retrieving its data and a handlebars template to display the data. Both of them can be overridden if needed, for e.g. to fetch and display information in a different way.

To enable it, add following in the Topbar definition in Helium.xml.

...
<TopBar>
    <Right>
        <Menu>tvc:menu:helium:recentobject/RecentlyViewed.xml</Menu>
    </Right>
</TopBar>
...
Looking to configure recent objects in a widget instead? See Recent Object Widget Configuration for more information.
Themes

"Themes" is a built-in dynamic menu which when configured gives user capability to switch between themes in real time. The built-in menu uses tvc.helium.themes property for retrieving the list of themes. Default value of this property is flat and light as tvc.helium.themes=flat|light.

To enable it, add following in the Topbar definition in Helium.xml.

1.1.3. PageMapping

The <PageMapping> element controls which type of objects should be mapped to which pages. It is possible to control the page mapping based on object type, object state and which access role the user belongs to.

This is done by creating a tree of Page elements with different rules. Given the following example:

<PageMapping>
   <!-- Evaluate the 'PartPage' if the type of the current object is a part
       and the state of the object is 'Released' and the current user belongs
       to the 'SeniorDesignEngineer' or 'ManufacturingDesignEngineer' roles,
       otherwise try the next page. -->
    <Page namespace="helium" name="PartPage.xml">
        <Type is="type_Part" and="current == Released">
            <Access>
                <Role>role_SeniorDesignEngineer</Role>
                <Role>role_ManufacturingDesignEngineer</Role>
            </Access>
        </Type>
    </Page>

    <!-- If the above rule evaluates to false and the current object is of the 'Part'
         type, evaluate 'OtherPartPage.xml' -->
    <Page namespace="helium" name="OtherPartPage.xml">
        <Type is="type_Part" />
    </Page>

    <!-- If the type of the page is ECR, evaluate the 'ECR.xml' page -->
    <Page namespace="helium" name="ECR.xml">
        <Type is="type_ECR" />
    </Page>

    <!-- If none of the above are true, evaluate the DefaultPage.xml -->
    <FallbackPage namespace="helium" name="DefaultPage.xml" />
</PageMapping>

The framework will try to evaluate the different pages from top to bottom until one of the criteria is met. If no criteria is met, the <FallbackPage> will be evaluated.

The <PageMapping> element supports the following child elements.

Name Description Example

Page

Specifies the current Page to evaluate via the namespace and name attributes.

Only evaluate the page if the rules given via the child elements <Type> and <Access> evaluate to true, otherwise try the next page.

 
<!-- Evaluate the 'PartPage.xml'... -->
<Page namespace="helium" name="PartPage.xml">
        <!-- ...if the current object type is 'Part'
        and current state is 'Released'... -->
        <Type is="type_Part" and="current == Released">
        <!-- ...and if the current user belongs to the roles below -->
        <Access>
           <Role>role_SeniorDesignEngineer</Role>
           <Role>role_ManufacturingDesignEngineer</Role>
        </Access>
    </Type>
</Page>

FallbackPage

The page to fall back to if none of the above rules have been applied. Supports the namespace and name attributes.

 
<FallbackPage namespace="helium" name="DefaultPage.xml" />
