You can configure the Panel G Wizard to store the file path as a relative
path or as an absolute path. If the VI that you connect to the button is
generally kept in a path that is relative to the top-level VI, you should
select the Relative path setting.
How Do You Configure Security
with the Panel G Wizard?
The Panel G Wizard can create code that disables or hides the button if the
operator does not have sufficient security access. You determine the access
level required in the Panel G Wizard dialog box. Security is covered later
in this chapter.
How Do You Configure When a Button
Will Be Polled?
Like all user interface controls in BridgeVIEW, front panel buttons are
monitored using a polling loop mechanism. Polling will occur either until
the BridgeVIEW Engine shuts down, or, if the Always option is selected,
until the VI stops.
Activity 7-1. Use the Panel G Wizard
Your objective is to use the Panel G Wizard to attach buttons to VIs that
you have created, to the HTV, and to a Login prompt. You will use VIs that
you created in Chapters 4, 5, and 6 in this exercise. You will use
mytanks.scf
in the
BridgeVIEW\Activity
directory.
