Additional features

Miscellaneous features of dynamic dialogs.

Defining cell attributes

In order to display array cells with colors in a list controlled by a dynamic dialog, you can define a two-dimensional dynamic array to hold cell attributes:

DEFINE attrs DYNAMIC ARRAY WITH DIMENSION 2 OF STRING
...
LET attrs[row,col] = "red reverse"
...
CALL d.setArrayAttributes("custlist", attrs)

If all cells of the array must get the same display attributes, use a simple DYNAMIC ARRAY OF STRING.

Handling rowset sorting

With a dynamic dialog controlling a list container that allows rowset sorting (like a TABLE), the sort event can be detected with the "ON SORT" event name.

When the "ON SORT" event occurs, the dynamic dialog can perform the same operations as when in a static DISPLAY ARRAY or INPUT ARRAY using the ON SORT interaction block:

    CALL d.addTrigger("ON SORT")
    ...
    WHILE (t := d.nextEvent()) IS NOT NULL
        CASE t
            ...
            WHEN "ON SORT"
                MESSAGE SFMT( "Row: %1/%2",
                    d.arrayToVisualIndex( "sr", d.getCurrentRow("sr") ),
                    d.getArrayLength( "sr" )
                )
    ...
