Modifying an
existing style
The easiest way to get started building form styles is to copy an
existing form style and work with it. By examining its structure and
making small changes, you can quickly understand how form styles
work.
To begin by modifying an existing form style:
-
Open the Library painter in PowerBuilder.
-
Copy the window and menu that serve as the foundation for a form
style to a library that is on your application’s library search
path.Starting from a built-in form style
The windows and menus that serve as the basis for the built-in
form styles are in IMSTYLE190.PBL, which is shipped with InfoMaker
and installed in the InfoMaker 2019 R3 directory. You can make a
copy of this PBL and use it as the basis of your own form
styles. -
Open the window in the Window painter and select File>Save As
from the menu bar to save it with a new name. -
Give the window a new name.
You can use any name you want, except that names of windows that
define form styles must be unique across all style libraries that are
used by an InfoMaker user. -
Define a special comment for the window (for instructions, see
Identifying the window as
the basis of a style). -
Click OK to save the window.
-
Open the menu in the Menu painter and select File>Save As
from the menu bar to save it with a new name. -
Provide a new name and an optional comment, then click OK to
save the menu.You do not need to provide a comment for the menu, but it is a
good idea to identify it as being used in the form style you are
building. -
Enhance the form style (for instructions, see Completing the style
).
