Only one prompt can be active at a time.
When the user presses a button, the button presses are returned as one of the following options:
• OK: display.BUTTON_OK
• Cancel: display.BUTTON_CANCEL
• Yes: display.BUTTON_YES
• No: display.BUTTON_NO
To capture return values, you need to use displaywait.event() to wait for the user button
selection.
Example
smu.source.sweeplinear("test", 1, 10, 10)
display.prompt(display.BUTTONS_YESNO, "Would you like to start the sweep now?")
sweepTest, result = display.waitevent()
if result == display.BUTTON_YES then
trigger.model.initiate()
end
display.prompt(display.BUTTONS_YESNO, "Would you like to switch to the Graph
screen?")
promptID, result = display.waitevent()
if result == display.BUTTON_YES then
display.changescreen(display.SCREEN_GRAPH)
end
Create a linear sweep.
Display the prompt "Would you like to start the sweep now?"
If the user presses Yes, the sweep starts.
If the user presses No, the sweep does not start and the message is removed.
