Special rules for scrolling text

The Scrolling Text Element includes special properties that can be applied at the item level, rather than just at the element level. This allows for customized styling and behavior for individual text items inside the scrolling text. These item-level rules enable dynamic changes, such as modifying the foreground color of a specific text item or changing the separator based on a data condition.

Applying rules to individual scrolling text items

When a rule is triggered, it can modify multiple properties, including:

• Making the entire scrolling text element invisible
• Adding a border around the scrolling text
• Adjusting the position or size
• Changing font or foreground color for individual items

Rules can be used on:

1. A play list of multiple text items
2. A scrolling text element linked to a data provider (e.g., displaying multiple rows of data)

Each separate item in the scrolling text can be validated independently based on the current data selection.

Change font & foreground color based on a rule

A rule can be added to validate text content and apply a font and foreground color change when a condition is met.

Example: Highlighting a specific line in a scrolling text

1. Data Source Example
   Line one  
   Line two  
   Line three  
   
2. Steps to Implement:
   • Connect a Scrolling Text Element to a static data provider containing the text data.
   • Enable Data Scrolling.
   • Set Scroll Options to Directly after previous text.
   • Add a rule:
     IF Current Data Equals ‘Line two’
   • Click Set Properties → Change Foreground Color (e.g., make it red).
   • Press F2 to preview → Line two will display in red, while the rest remain unchanged.

​

Example: Applying a rule to multiple lines

• If the rule is instead:
  IF Current Data Starts With ‘Line’,
  all lines would be affected and displayed in the same color.

Changing the separator based on a rule

This example demonstrates how to create a stock exchange ticker using the Scrolling Text Element with dynamic separator images based on stock price movement.

​

Data source example

​

Steps to implement

1. Connect a Scrolling Text Element to a static data provider with stock data.
2. Enable Data Scrolling.
3. Set Scroll Options to Directly after previous text and select the Description column for the scrolling text.
4. Add a rule:
   • IF CurrentPrice is greater than OldPrice → Set a green separator image (▲ Uptrend).
   • IF CurrentPrice is less than or equal to OldPrice → Set a red separator image (▼ Downtrend).

​

Results

• Coca Cola 42.40 (Price increased) → Green Separator
• Microsoft 65.22 (Price decreased) → Red Separator
• Google 820.19 (Price decreased) → Red Separator

Key takeaways

• Rules allow item-level customization in scrolling text.
• Individual text items can have different fonts, colors, and separators based on real-time data validation.
• Database values can control how text content and separators appear dynamically.
• Multiple columns can be used for rule validation, not just the one displayed.
