UI.Toggle

static bool Toggle(string text, Boolean& value)

A toggleable button! A button will expand to fit the text provided to it, vertically and horizontally. Text is re-used as the id. Will return true any time the toggle value changes, NOT the toggle value itself!

   
string text Text to display on the Toggle and id for tracking element state. MUST be unique within current hierarchy.
Boolean& value The current state of the toggle button! True means it’s toggled on, and false means it’s toggled off.
RETURNS: bool Will return true any time the toggle value changes, NOT the toggle value itself!
static bool Toggle(string text, Boolean& value, Vec2 size)

A toggleable button! A button will expand to fit the text provided to it, vertically and horizontally. Text is re-used as the id. Will return true any time the toggle value changes, NOT the toggle value itself!

   
string text Text to display on the Toggle and id for tracking element state. MUST be unique within current hierarchy.
Boolean& value The current state of the toggle button! True means it’s toggled on, and false means it’s toggled off.
Vec2 size The layout size for this element in Hierarchy space. If an axis is left as zero, it will be auto-calculated. For X this is the remaining width of the current layout, and for Y this is UI.LineHeight.
RETURNS: bool Will return true any time the toggle value changes, NOT the toggle value itself!

Examples

A toggle button

A window with a toggle

Toggle buttons swap between true and false when you press them! The function requires a reference to a bool variable where the toggle’s state is stored. This allows you to manage the state yourself, and it’s completely valid for you to change the toggle state separately, the UI element will update to match.

Note that UI.Toggle returns true only when the toggle state has changed, and does not return the current state.

Pose windowPoseToggle = new Pose(.3f, 0, 0, Quat.Identity);
bool toggleState      = true;
void ShowWindowToggle()
{
	UI.WindowBegin("Window Toggle", ref windowPoseToggle);

	if (UI.Toggle("Toggle me!", ref toggleState))
		Log.Info("Toggle just changed.");
	if (toggleState) UI.Label("Toggled On");
	else             UI.Label("Toggled Off");

	UI.WindowEnd();
}
