Check Box Agony

[fortie04]

Hi All,

I’ve been struggling to figure out the best way to work with the Check Box and decided to turn here.
All I’m really trying to do is get the value (checked or unchecked) of the box. Then execute different functions depending on the result of the check box. (yes, very simple I know)

to test, I made a simple program with a check box and 3 buttons.
button 1 will get the true or false value of my property check box and log it to the console
button 2 will set the value of check box to false and will in turn deselect the box
button 3 will set the value of check box to true and will in turn check the box

the issue is when I manually click the check box and then look to get it’s status, it won’t reflect the changes.

Ive used bindings to connect the check box to my property checkbox

heres the code:

script checkItAppDelegate
	property parent : class "NSObject"
	property CheckBox : missing value
	
	
	on applicationWillFinishLaunching_(aNotification)
		set CheckBox to false
		-- Insert code here to initialize your application before any files are opened 
	end applicationWillFinishLaunching_
	
	on ClickIt_(sender)
		set my CheckBox to true
		-- CheckBox's setState_(true)
	end ClickIt_
	
	on GetStatus_(sender)
		if my CheckBox is true then
			log "its true "
		end if
		
		if my CheckBox is false then
			log "its false"
		end if
		
		
	end GetStatus_
	
	on UnClickIt_(sender)
		--CheckBox's setValue_(false)
		set my CheckBox to false
		
end UnClickIt_
	
	on applicationShouldTerminate_(sender)
		-- Insert code here to do any housekeeping before your application quits 
		return current application's NSTerminateNow
	end applicationShouldTerminate_
	
end script

I had to use the set my checkbox to false rather than the CheckBox’s setValue_(false) because the latter wasnt working for some reason.

thanks for the help

Hi fortie04
i have been using this style to get and set check box values, see how it goes for you

script get_and_set_check_boxAppDelegate
	property parent : class "NSObject"
	
	property checkboxinfo : missing value
	
	on CreateInfo_(sender)
		
		checkboxinfo's intValue() --return 1 or 0
		
		display dialog result
		
		checkboxinfo's setIntValue_([1]) --set check box to 1 or 0
		
		display dialog result
		
	end CreateInfo_

This is partly working for me.
I think it’s required to set the initial value to 0 during the “applicationWillFinishLaunching”

If I just get the value of the box before I check/uncheck the box it won’t return an intValue at all.

What is the difference between setting the intValue to 1 or 0 with cocoa ( chcekbox’s setIntValue_(0))
or just setting it with AS: set my checkbox to 1 or 0

thanks

on applicationWillFinishLaunching_(aNotification)
		set CheckBox to false
		-- Insert code here to initialize your application before any files are opened 
	end applicationWillFinishLaunching_

Make that:

		set my CheckBox to false

on GetStatus_(sender)
		if my CheckBox is true then
			log "its true "
		end if
		
		if my CheckBox is false then
			log "its false"
		end if
	end GetStatus_

Try:

 if (my CheckBox) as boolean = true then

You also shouldn’t capitalize the name of properties.

[StefanK]

you can get and set the state of a checkbox with it’s state property.

@StefanK

you can get and set the state of a checkbox with it’s state property.

Yes, although the OP said he was using bindings. Either way, a coercion of the result will be needed.

[fortie04]

If I was to use the setState property would I no longer need bindings?

It seems like bindings are the best way to go because it will update immediately with the lease amount of code.
Should I pass setState a true/false argument or a 1/0 argument?

Also, It seems that a check box can be: True, False or Void.
What is the difference between false and void?

Shane, I’ve been using your coming to florida program to learn about bindings and the checkbox.

on applicationWillFinishLaunching_(aNotification)
		-- set some initial data
		set my theData to {{firstName:"Ray", lastName:"Robertson", isAlumni:true}, {firstName:"Shane", lastName:"Stanley", isAlumni:true}}
		set newAlumni to false -- sets it to a boolean
	end applicationWillFinishLaunching_

why do you not do:

set my newAlumni to false -- sets it to a boolean

Why is ASOC do you need to identify properties as “my”?

thanks for the feedback

Right.

It seems like bindings are the best way to go because it will update immediately with the lease amount of code.

That’s right. Less code is good.

Should I pass setState a true/false argument or a 1/0 argument?

It doesn’t matter – in Objective-C they’re much the same thing.

Also, It seems that a check box can be: True, False or Void.
What is the difference between false and void?

I’m not sure what you mean by void. You can set a checkbox to allow a third state, mixed.

Shane, I’ve been using your coming to florida program to learn about bindings and the checkbox.

on applicationWillFinishLaunching_(aNotification)
		-- set some initial data
		set my theData to {{firstName:"Ray", lastName:"Robertson", isAlumni:true}, {firstName:"Shane", lastName:"Stanley", isAlumni:true}}
		set newAlumni to false -- sets it to a boolean
	end applicationWillFinishLaunching_

why do you not do:

set my newAlumni to false -- sets it to a boolean

Probably an oversight…

Why is ASOC do you need to identify properties as “my”?

The simple answer is, well, because it doesn’t work properly if you don’t.

Thanks for all the help.
It’s working correctly now
