Describe the project you are working on:
I'm working on BlueTooth Poker 8 Free/Pro on Android
Describe the problem or limitation you are having in your project:
I must recompile the export templates because i don't want to open the virtual keyboard on spin boxes
Describe the feature / enhancement and how it helps to overcome the problem or limitation:
a check box which let the developer to choose between virtual keyboard automatically opened or not automatically opened
Describe how your proposal will work, with code, pseudocode, mockups, and/or diagrams:
a check box in Spin Boxes parameters and others which are emitting text_entered signal in Godot.
If this enhancement will not be used often, can it be worked around with a few lines of script?:
must recompile the export templates for each new version of Godot.
Is there a reason why this should be core and not an add-on in the asset library?:
It's about virtual keyboard which is core implemented
You can access the SpinBox's LineEdit with get_child() method and disable the keyboard. There's a property in LineEdit that allows it:

This is a workaround, but it's still better than recompilling templates.
Which version are you using? I'm using 3.2.2-stable and there is no such setting in LineEdit.
I think it was added for 3.2.3, you can try rc6, it's pretty stable already.
Thank you!
@DisDoh Closing the proposal as it seems to be resolved by the option that @KoBeWi provided. Feel free to reopen if that's not the case.
