How to make radio buttons in Godot 3.0?

Question

Hate to ask such a stupid question but I've spent too long searching for a way to make this work. They're checkboxes, right? There is no magical "ButtonGroup", adding a group to each checkbox does nothing, putting them in a container does nothing.
Is there a way to make radio buttons in Godot 3.0? TIA

Comments

I figured it out (I actually had a working example in the project I was working on...so dumb xD).
Create a new CheckBox and it has a "Group" property. Click the arrow, create a new ButtonGroup and name it. Then click the arrow again and Copy. Make another checkbox, click arrow --> Paste. Radio buttons.

Answer 1

This is an older question, but the only answer doesn't seem to be up-to-date.

If you create a CheckBox node, under the BaseButton section in the inspector you can create/define a Group (button group) for it. Copy this group for every radio box in the same group.

This is all you need to do, now the buttons act as radio buttons.

even normal button works, if toogle mode checked, tested in godot 3.1.1

Answer 2

I don't know if there is an official way to do this, but i've done this way:
First, i create a new scene with a CheckBox node, which i call RadioButton, and i save it as RadioButton.tscn. I add to it a script with this content:

extends CheckBox

func is_radio():
    pass

func _ready():
    pass

func _process(delta):
pass


func _on_RadioButton_toggled(button_pressed):
   if button_pressed:
        for child in get_parent().get_children():
            if child.has_method("is_radio"):
                child.pressed = false
                pressed = true
   else:
                pressed = true

Be sure you connect the toggled() signal to _on_RadioButton_toggled() function.
Then i instantiate in the scene i want the radio buttons as many as i want.

Note: I think this would work better if we use groups, but i've been using this way with no trouble at all.

I was so sure there would be a way to just have the checkboxes treated as radio buttons, but this is an excellent workaround. Thanks!
