A compact range entry with a calendar popup, minute precision, quick presets, and independently optional bounds.
Example
Usage
Filter by a date range
Open the compact entry, select two dates, or choose a whole-day preset. Query inclusion belongs to the application.

Methods
CalendarView* calendarView() constReturns the picker-owned range calendar for navigation and week settings.
CalendarDatePicker* startDatePicker() constReturns picker-owned inputs for formatting and accessibility setup.
void setRange(const QDateTime& start, const QDateTime& end)Updates both endpoints before emitting their change signals.
void setTimeEnabled(bool enabled)Shows time inputs or normalizes both endpoints to midnight.
void openPicker()Opens the same-window range calendar, endpoint editors, and presets.
void applyPreset(Preset preset)Applies a built-in preset relative to local today or a supplied reference.
Signals
void presetRequested(Preset preset)Requests a shortcut; disable auto application to supply business ranges.

static bool themeUsesDarkAppearance(Theme theme)Returns whether a theme uses dark-backed chrome and material tokens.
static void refreshTheme()Re-broadcasts the current theme to repaint after a design-token change.
static int themeGeneration()Monotonic counter bumped on every theme change, for staleness checks.
Theme effectiveTheme() constResolves the theme used by this element, honoring an inherited QWidget override.
bool effectiveThemeUsesDarkAppearance() constReturns whether this element's effective theme uses dark-backed chrome.
bool setThemeOverrides(const QJsonObject& overrides)Component-facing token accessors.
QJsonObject themeOverrides() constReturns this element's authored overrides.
void clearThemeOverrides()Restores all token fields to global theme defaults.

Methods
AnchorLayout::Anchors* anchors()Returns mutable anchors for the QWidget host.
void setState(const QString& name)Applies a named state, or clears state when name is empty.
void addState(const QMLState& state)Registers or replaces a named state definition.
void evaluateStates()Reevaluates conditions; the first registered true condition wins.
QMLPlusRuntime* runtime()Returns the lazy host-owned state observation object.
void setAnchors(const AnchorLayout::Anchors& anchors)Replaces all host anchors and invalidates the parent layout.
void resetAnchors()Clears all host anchors and invalidates the parent layout.
void bind(const char* targetProp, QObject* source, const char* sourceProp, PropertyBinder::Direction dir = PropertyBinder::OneWay)Binds a source property to a property on the QWidget host.
BindingHandle bindManaged(const char* targetProp, QObject* source, const char* sourceProp, PropertyBinder::Direction direction = PropertyBinder::OneWay, BindingOptions options = {})Installs a managed direct binding on this QWidget host.
BindingHandle bindComputed(const char* targetProp, const QVector<BindingDependency>& dependencies, std::function<QVariant()> evaluate, BindingOptions options = {})Installs an explicit-dependency C++ expression on this QWidget host.
void addTransition(const StateTransition& transition)Registers a state transition in precedence order.
void setBehavior(const char* propertyName, const PropertyAnimation& animation)Sets the default animation for this host's managed property writes.
void clearBehavior(const char* propertyName)Removes the default animation for future managed writes.
bool writeProperty(const char* propertyName, const QVariant& value)Writes a host property through Behavior without removing its binding.
