Use of newline character sequence (backslash n) in UI Button Text

[Randal_Andress]

I have seen the thread:
button-text-formatting

Still I cannot sort out whether or not (or under what conditions) this is meant (can be expected) to work.

I am unable to get \n to generate a new line on Button Text as it does on Label Text.

Is there a parameter that can be set via an extension? Evidently, if Text Input Type "is set to TYPE_TEXT_VARIATION_PERSON_NAME then it does not allow multiline support". (from referenced post).

Is there some other type of extension that will solve this? such as a Button extension?

Any comments or help in pointing me in the right direction will be greatly appreciated!

Kind regards,

Works on a Samsung A13 Android 13.

Hello\nWorld results in
Hello
World

in a Button while using any of these Themes

Are you using an ios device?
Are you using Companion 2.68?

Thanks for the test result ... I am on an older deivce/OS:
moto e5 play, Android 8.0.0, using theme Device Default.

And yes, I am using Companion 2.68.

What do you suggest (besides upgrading my phone?

[addendum]

Using the TestInputType extension from the referenced post:

Doit result is "0".

@Randal_Andress

What do you suggest

Don't use multiple line Buttons. Inability to use multiple lines might be a bug specific to your device so use a different way to display using a different component; put text in an image and display that in the Button; use a Label or a ListView etc.

Did you change other Button Properties? For instance Shape. Or set Height to other than Automatic?

...Inability to use multiple lines might be a bug specific to your device

... AND even if it is not (a device specific bug), based on what I am reading from you and the other post, it COULD be. And if I expect the app to work on other devices then (as you suggested in line 1), I should not depend on multi-line Button text.

@SteveJG

...put text in an image and display that in the Button; use a Label or a ListView etc.

A label is what I WAS using ... I need the multi-function button-display to conserve real estate - image & ListView - good ideas!

@SteveJG

I may try that, but I fear that any success could be a device-specific workaround

I am hopeful that your diagnosis and good ideas will get me there.

Thanks,

[Addendum]
I was naively expecting to find in the builtin blocks the needed conversion of "text to image" or "label to image".

Did I overlook it or does this require an extension or something else?

[Randal_Andress]

Well, your diagnosis was correct - and in an Occam's Razor sort of way that is embarrassing

I increased the height of the Button and "presto!" - two lines.

The display in the Design mode showed the unformulated text as one line, e.g.:
"Line One\nLine Two"

But when executed in the app (with sufficient helght):
Line One
Line Two

Before increasing the height I had gotten:
Line One

...which should have been a clue that there was not room for the second line.

Evidently my Button needed more height than the Label that it replaced to display two lines.

I greatly appreciate your thoughtful replies.
