User Input, Checkbox, default value from variable

Hi,

Curious if there is a way to have the user prompt display with a checkbox that gets it’s on / off status from a variable? That is, if variable “Full” is 1, then the prompt would display a checkbox already checked with the variable name to the right of the checkbox.

Does that make sense?

Thanks

Of course. This:

…will produce this:

Great help, thanks Tom. Looking at it now it makes perfect sense that this is how it would work. Now that I can do this I wrote a quick AppleScript to convert variables with a 1 into 1|0 and variables with a 0 into 0|1 and then ran the input prompt as intended.

You don’t need to do that, you can var %Variable%MyVar%|0|1

Keyboard Maestro uses the first entry as the default/selected entry (hence uses the 0 or 1 from the variable to set the initial value), and is smart enough to see that even though there are three values, they are all 0 or 1, so it is still a checkbox.

Brilliant. This is what I was hoping for. Thanks so much Peter

Hello @Tom, thank you very much for the posted macro :ok_hand: Since I'm not a KM nerd, I have a question about the "set variable..."

You use here for the first 0|1 and the second 1|0. If I continue this with 2|0 and 3|0, these are selected directly when calling.
However, if I mark them all with 0|1, then I can call up and activate/deactivate them all.

It works so well for me :+1:

My question now is whether my settings are correct or whether it just happens to work for me? If I did something wrong, you could help me out?

Enclosed my macro...

08)Everyone copy.kmmacros (8,6 KB)

1|0 simply means ‘checkbox selected’, 0|1 means ‘checkbox not selected’. (By default.)

I don’t know what 2|0 and 3|0 should do. The KM Wiki article doesn’t mention it. But maybe I’m missing something or this is something new. (If this is not something new then I guess that 2|0 or 3|0 works just like 1|0)

Not sure if I understand. Also when they are set to 1|0 you should be able to select/deselect the checkboxes. The 1|0 or 0|1 just sets the state of the checkbox when the prompt comes up. Once you actually select/deselect a checkbox the new value (0 or 1) is used.

Thank you for your quick answer. It was my mistake of thought that I meant…
1|0 = Icons
2|0 = Desktop
3|0 = Night Shift
etc.
would have something to do with the number/arrangement (numbering) of the checkboxes and would not be marked or unchecked. Just as the variables are numbered consecutively.

For me it was/is important that the input window opens and no checkbox is checked. I did, yes, I did, even though unconsciously. Thank you very much again.

By choosing the format n|n (where n is either ‘0’ or ‘1’) you are telling the prompt that the input field should be a Checkbox Input Field (and not a text input field etc.).

Then, by either putting 1 or 0 on the first position you tell the prompt what the default state of that Checkbox should be (0|1: off; 1|0: on).

Yep, don’t hesitate to ask in the forum. Plenty of helpful people here. Also the KM Wiki (which has improved significantly over the last years) provides a lot of useful information. I’m also looking up things on the Wiki frequently.

Seriously! Even the last ~12 months have shown huge improvement in readbility and cross referencing.

I think this is mainly thanks to the work of @JMichaelTX, @peternlewis, @ccstone. And, of course, many of the improvements to the Wiki originate from (or are inspired by) questions and contributions by many forum members.

Ehm, sorry, just read your post again (sometimes I’m a bit slow). What you probably wanted to do —I think— is constructing a popup button (not a check box). Like this:

You can do this with this:

[example] Popup Button.kmmacros (3.0 KB)


You can also differentiate between the displayed value and the “real” value by prepending the real value to the displayed value, separated by 2 underscores:

Thank you for the information on the pop-up button :ok_hand:
I expressed myself wrongly from my side. I assumed that I would have to continue the enumeration for further checkboxes, as shown on the ScreenShot...

Now I know that this is underexposed for the function of the checkboxes. Thanks to your help, I'm now aware of the behavior of 0|1 and 1|0.

Can I use your macro for a YouTube tutorial? Of course I would link your contribution as a source in my tutorial.

Ah, OK, I got now what you meant.

Of course, yes.
