Thus far we have always used our layout without properties or parameters and so we have used the short syntax.

Layouts can have properties and parameters as well. They can also be named. To name a layout when the short syntax is used:

 SimpleStack:MyStack

   Text One

   Text Two

   Text Three

 

Stack

 

SimpleStack does not accept a parameter and has minimal properties. Let's change SimpleStack to Stack:

   Text One

Layout Properties

 

Stack is a more capable layout than SimpleStack, but it also emits more HTML. The most commonly used property of Stack is .Orientation. Orientation can be set as a property:

 Stack

   Orientation: Horizontal

   Edit Hello World

   gap;

   Button OK

 

Layout with Parameters

 

Many layout controls support the use of parameters also. For Stack, the parameter corresponds to the .Orientation property. Thus we can rewrite the above IWML as:

 

[iw-app]

 

If we need to set other properties not supported by the parameter, then we must revert back to the full syntax.
