Widget Properties
The outlooking, behavior, location and size of widgets are called properties. Properties can be set in property
sheet in editing mode, and could also be changed in attached rules or scripts in Runtime. The value of the any
property can be accessed with Property Macro via property_id.
In most cases, the property_id is following this convention corresponding to the property name:
-
lower case of all characters

replace space with underscore.
For Example: The property_id of "Foreground Color" is "foreground_color".
