Inheritance diagram for LuaDebuggerVariablesController:

Public Slots
void	showContextMenu (const QPoint &pos)
	Displays the context menu for the variables tree.
void	onExpanded (const QModelIndex &index)
	Handles the event when a tree node is expanded.
void	onCollapsed (const QModelIndex &index)
	Handles the event when a tree node is collapsed.

Public Member Functions
	LuaDebuggerVariablesController (LuaDebuggerDialog *host)
	Constructs a new LuaDebuggerVariablesController object.
void	attach (QTreeView *tree, QStandardItemModel *model)
	Attaches the controller to the given tree view and model.
void	configureColumns () const
	Configures the tree view columns for the variables panel.
void	restoreExpansionState () const
	Re-expand Locals/Globals/Upvalues after a variables refresh.
void	rebuildFromEngine ()
	Clear the model, re-fetch Locals/Globals/Upvalues from the engine, and re-apply persisted expansion.
void	fetchAndAppend (QStandardItem *parent, const QString &path)
	Append children of path under parent (or as new top-level rows when parent is null). Used by rebuildFromEngine for the initial Locals/Globals/Upvalues fetch and by onExpanded for lazy descent into nested tables. Reaches back to the dialog for change-highlight baselines and the active stack frame.
QStandardItem *	findItemByPath (const QString &path) const
	Finds a tree item based on its path.
QHash< QString, LuaDbgTreeSectionExpansionState > &	expansionMap ()
	Retrieves the mutable expansion state map.
const QHash< QString, LuaDbgTreeSectionExpansionState > &	expansionMap () const
	Retrieves the read-only expansion state map.

Constructor & Destructor Documentation

LuaDebuggerVariablesController()

LuaDebuggerVariablesController::LuaDebuggerVariablesController ( LuaDebuggerDialog *  host )

explicit

Constructs a new LuaDebuggerVariablesController object.

Parameters

host	Pointer to the hosting Lua debugger dialog.

Member Function Documentation

attach()

void LuaDebuggerVariablesController::attach	(	QTreeView *	tree,
		QStandardItemModel *	model
	)

Attaches the controller to the given tree view and model.

Parameters

tree	Pointer to the tree view for displaying variables.
model	Pointer to the item model for variables.

expansionMap() [1/2]

QHash< QString, LuaDbgTreeSectionExpansionState > & LuaDebuggerVariablesController::expansionMap ( )

inline

Retrieves the mutable expansion state map.

Returns

Reference to the hash map storing tree section expansion states.

expansionMap() [2/2]

const QHash< QString, LuaDbgTreeSectionExpansionState > & LuaDebuggerVariablesController::expansionMap ( ) const

inline

Retrieves the read-only expansion state map.

Returns

Const reference to the hash map storing tree section expansion states.

fetchAndAppend()

void LuaDebuggerVariablesController::fetchAndAppend	(	QStandardItem *	parent,
		const QString &	path
	)

Append children of path under parent (or as new top-level rows when parent is null). Used by rebuildFromEngine for the initial Locals/Globals/Upvalues fetch and by onExpanded for lazy descent into nested tables. Reaches back to the dialog for change-highlight baselines and the active stack frame.

Parameters

parent	The parent standard item to append to, or nullptr for top-level.
path	The path string indicating the variable to fetch.

findItemByPath()

QStandardItem * LuaDebuggerVariablesController::findItemByPath

(

const QString &

path

)

const

Finds a tree item based on its path.

Parameters

path	The path of the item to find.

Returns

Pointer to the found QStandardItem, or nullptr if not found.

onCollapsed

void LuaDebuggerVariablesController::onCollapsed ( const QModelIndex &  index )

slot

Handles the event when a tree node is collapsed.

Parameters

index

The model index of the collapsed item.

onExpanded

void LuaDebuggerVariablesController::onExpanded ( const QModelIndex &  index )

slot

Handles the event when a tree node is expanded.

Parameters

index

The model index of the expanded item.

showContextMenu

void LuaDebuggerVariablesController::showContextMenu ( const QPoint &  pos )

slot

Displays the context menu for the variables tree.

Parameters

pos	The point where the context menu should be displayed.
