STACK container
The STACK
container holds stack items defining
a logical alignment of form items.
Important:
This feature is experimental, the syntax/name and semantics/behavior may change in a future version.
Syntax
STACK
{ scalable-item
| container-list
}
END
where container-list
is:
grouping-item
leaf-item
[...]
END
[...]
- scalable-item is a leaf element of the stacked layout, for widgets with a scalable width and height.
- grouping-item is a stacked layout grouping element that holds a list of leaf-items.
- leaf-item is a leaf element of the stacked layout, for widgets with a fixed size (non-scalable).
Can hold
Scalable stack items: IMAGE
, TEXTEDIT
,
WEBCOMPONENT
.

Usage
The STACK
container is used to define a stack-based layout.
Note: Unlike grid-based containers (
GRID
) where element definition
is split in the LAYOUT
and ATTRIBUTES
sections, the items in a
STACK
container define both the position and attributes.The STACK
container must appear immediately after the
LAYOUT
keyword.
The
STACK
container typically defines a list of elements (such as
GROUP
, FOLDER
, TABLE
),
grouping leaf stack items (such as form fields)
together:LAYOUT
STACK
GROUP custinfo (TEXT="Customer info")
EDIT customer.cust_num, TITLE="Num:", NOENTRY;
EDIT customer.cust_name, TITLE="Name:", SCROLL;
...
END
TABLE cust_orders (STYLE="compact_list", DOUBLECLICK=select)
LABEL orders.ord_num, TITLE="Num";
LABEL orders.ord_ship, TITLE="Ship date";
LABEL orders.ord_value, TITLE="Value";
...
END
...
END
END
A stack container can also define a single scalable stack item, such as an
IMAGE
, TEXTEDIT
, or WEBCOMPONENT
:
STACK
IMAGE FORMONLY.picture;
