Overview
The billboard control allows you to incorporate billboards (an image slideshow, or single images) on your custom screens or custom progress screens. The billboard control contains many settings that can be configured to suit your presentation, such as: background style, border style, image duration, resize modes, auto-start, looping, shuffle, image transition effects, and many more.
Additional features of the billboard control can be found in the following two categories:
A notification message is triggered whenever the user interacts with a control, or whenever user interaction affects a control in some way. Each notification message consists of a number that identifies the type of interaction that has occurred, and a table containing details specific to that type of interaction. These two values are passed to the screen's On Ctrl Message event as the event variables e_MsgID and e_Details.
Note: Notification messages are not triggered when actions interact with this control.
(number)
e_MsgID
A numeric constant that represents the specific notification message that
was fired by the screen control. See the e_MsgID column below for all
possible message ids that can be fired by a billboard control.
(table) e_Details
A table of additional details that may be passed by the control
when certain notification messages are fired. See the e_Details column
below for the kinds of details that are returned and the table indexes
that you can use to access them.
