class simvx.core.ui.advanced.CheckBox(text: str = '', checked: bool = False, on_toggle=None, **kwargs)[source]

Bases: simvx.core.ui.core.Control

Toggle control with a check box and label text.

Example: cb = CheckBox(“Enable Feature”, checked=True) cb.toggled.connect(lambda on: print(“Checked:”, on))

content_signature() object[source]
content_uses(chars: str) bool[source]
activate() bool[source]

Toggle, the way a click does: ui_accept flips a focused check box.

Matches Godot (CheckBox is a button, so ui_accept toggles it) and Unity (Toggle implements ISubmitHandler). Note the default focus_mode is NONE, so this only ever runs for a check box an author made focusable.

class simvx.core.ui.advanced.SpinBox(value: float = 0, step: float = 1, **kwargs)[source]

Bases: simvx.core.ui.core.Control

Blender-style numeric field: value always visible, arrows on sides, drag to scrub.

Interaction modes:

  • Display: Shows formatted value centred. Arrows < > on hover.

  • Drag: Mouse-down + horizontal drag scrubs value by step per pixel.

  • Click: Mouse-down + release without dragging enters edit mode.

  • Edit: Type a new value. Enter commits, Escape cancels.

  • Scroll: Mouse wheel increments/decrements by step.

Example::

spin = SpinBox(min_value=0, max_value=100, value=50, step=5)
spin.value_changed.connect(lambda v: print("Value:", v))

class simvx.core.ui.advanced.RadioButton(text: str = '', group: str = '', selected: bool = False, **kwargs)[source]

Bases: simvx.core.ui.core.Control

Mutually exclusive toggle within a named group.

Only one RadioButton per group can be selected at a time. Clicking one automatically deselects siblings in the same group.

Example: r1 = RadioButton(“Option A”, group=”opts”) r2 = RadioButton(“Option B”, group=”opts”) r1.selection_changed.connect(lambda on: print(“A:”, on))

Select this option, the way a click does; an already-selected one holds.

Deselecting is not an option a radio button offers, so the key is consumed either way. Default focus_mode is NONE: only a radio button an author made focusable is ever activated from the keyboard.
