Code runs too fast!

I have my app running just fine. The basic app is this, 2 buttons, Start and Stop. Click on Start and the app starts checking for the current state of the power source. In theory, click on Stop and the app stops. The problem is, you can’t click on Stop. My coding is such that it is running so fast continually calling the PowerStatus handler that the buttons are never checked and can’t even be clicked on.

I am new to coding in Applescript ObjC. What I want is to have a routine that continues to run until the condition of “Stop button = Enabled”

This is my code as is now and will show how new I am to this.

script Power_DetectorAppDelegate
	property parent : class "NSObject"
	property startButton : missing value
	property stopButton : missing value
	property checkTime : integer
	property currTime : integer
	on awakeFromNib()
		set checkTime to 0
	end awakeFromNib
	on clickStartButton_(sender)
		set statStartButton to my startButton's |state|() as integer
		repeat while (statStartButton = 1)
			set the title of startButton to "Running"
			set the title of stopButton to "Stop"
			my startButton's setEnabled_(false)
			my stopButton's setState_(false)
			set statStopButton to 0
			set currTime to time of (current date) as integer
			delay 5
		end repeat
	end clickStartButton_
	on getPowerStatus_()
		set PowerSource to (do shell script "pmset -g ps")
		if currTime < 300 then
			set checkTime to 0 --resets for midnight
		end if
		if PowerSource does not contain "AC Power" then
			if (currTime > checkTime + 300) then --check every 5 minutes (300 seconds)
				--send Ryan alerts
				set recipientRyanEmail to ""
				set recipientRyanSMS to ""
				set recipientRyanName to "Ryan"
				set theSubject to "POWER ALERT!"
				set theContent to return & "Power issues at the FIC!"
					tell application "Mail"
						--Create the message
						set theMessage to make new outgoing message with properties {subject:theSubject, content:theContent, visible:false}
						--Set a recipient
						tell theMessage
							--messages to Ryan
							make new to recipient with properties {name:recipientRyanName, address:recipientRyanEmail}
						end tell
					end tell
				end try
				set checkTime to time of (current date) as integer
			end if --(currTime > checkTime + 300)
		end if --PowerSource does not contain "AC Power"
		set currTime to time of (current date) as integer
	end getPowerStatus_
	on clickStopButton_(sender)
		set statStopButton to my stopButton's |state|() as integer
		set the title of startButton to "Start"
		set the title of stopButton to "Stopped"
		my startButton's setState_(false)
		my startButton's setEnabled_(true)
		set statStartButton to 0

	end clickStopButton_
	on idle
		display dialog "Hello"
	end idle
	on applicationShouldTerminate_(sender)
		-- Insert code here to do any housekeeping before your application quits 
		return current application's NSTerminateNow
	end applicationShouldTerminate_
end script

I think I have fixed my own code. Thoughts on this? I found an idler in the forums and ran with it:

on loopCheck_(sender)
		set statStartButton to my startButton's |state|() as integer
		if statStartButton = 1 then
		end if
		if statStartButton = 0 then
			statusUpdateTimer's invalidate()
		end if
	end loopCheck_

Now, I have full control of my app using an NSTimer call to “loopCheck:”.

You really don’t want to use "delay’ in AsObjC projects – it drives your CPU use to the max, for starters.

What you need to do is use an NSTimer rather than a repeat loop. You set up a timer that calls a handler every x seconds. If you have a hut around here, you’ll see several posts on how to use a timer.
