Using regular DISPLAY ARRAY control blocks
Simple table DISPLAY ARRAY
control blocks can be used with
tree-views.
If needed, you can implement traditional
DISPLAY ARRAY
control blocks like
BEFORE ROW
or AFTER
ROW
:DISPLAY ARRAY tree_arr TO sr.* ATTRIBUTES(UNBUFFERED)
BEFORE ROW
DISPLAY "BEFORE ROW - Current row is: ", DIALOG.getCurrentRow("sr")
AFTER ROW
DISPLAY "AFTER ROW - Current row is: ", DIALOG.getCurrentRow("sr")
END DISPLAY
