You can open an existing ABL GUI procedure (.w) file with the
ABL UI Designer or ABL Editor.
To open an ABL GUI procedure (.w) file:
In the Project Explorer view, right-click a procedure file name and
select Open With from the context menu.
Choose one:
OpenEdge ABL Editor to display the source code.
ABL UI Designer to display the design editor.
Alternatively, you can simply double-click the procedure file in the Project
Explorer view. Progress Developer Studio for OpenEdge opens the procedure file
either in a ABL UI Designer editing window or in the ABL Editor, whichever you
last selected when opening the file with the Open With
command. If you have not previously used Open With for
the file, by default it opens in the ABL UI Designer.
Note: You
cannot open multiple instances of the same file in the ABL UI
Designer.
