Attributes
Controls or expressions can also be referenced for element
attribute values. Select Edit/Add Attribute from the pop-up menu for
elements to edit an existing attribute or add a new one.
For each attribute specified, you can select a control reference
from the drop-down list or enter a literal text value. A literal text
value takes precedence over a control reference. You can also use the
expression button to the right of the Text box to enter an
expression.
The expression button and entry operates similarly to DataWindow
object properties in the Properties view. The button shows an equals
sign if an expression has been entered, and a not-equals sign if not.
A control reference or text value specified in addition to the
expression is treated as a default value. In the template, this
combination is stored with the control reference or text value,
followed by a tab, preceding the expression. For example:
1 |
attribute_name=~"text_val~~tdw_expression~" |
