DataGrid
Presents large model-backed rows and columns with headers, sorting, selection, and delegate editing.
Example
Usage
Pinned columns and editing
Scroll horizontally while Project stays visible. Double-click a cell or press F2 to edit.

Methods
void setModel(QAbstractItemModel* model) overrideInstalls a caller-owned model and refreshes table semantics.
void setSelectionModel(QItemSelectionModel* selectionModel) overrideInstalls a caller-owned selection model.
void setColumnPinned(int column, bool pinned)Pins a logical column to the leading edge without copying its model.
void setColumnVisible(int column, bool visible)Changes column visibility and emits columnLayoutChanged on a real change.
QByteArray saveColumnState() constSerializes column order, widths, visibility, pinning and sort indicator.
bool restoreColumnState(const QByteArray& state)Restores a validated layout for the same model schema; invalid data is a no-op.
fluent::scrolling::ScrollBar* verticalFluentScrollBar() constReturns the Fluent overlay scrollbar mirroring the native range.
fluent::scrolling::ScrollBar* horizontalFluentScrollBar() constReturns the Fluent horizontal overlay scrollbar.

static void setTheme(Theme theme)Updates the global theme and notifies active FluentElement instances.
static void setThemeDeferred(Theme theme)Schedules a visible-first batched theme refresh without blocking the current interaction.
static Theme currentTheme()Returns the currently active global theme.
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.
const Colors& themeColorsRef() constNon-copying access to the active color set (for hot paint paths).

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.
