Overview
A button control is a visual component of a screen that can be clicked by the user and responded to with action script. Examples of button controls can be seen below:
Additional features of the button 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 button 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.
