void	setFilename (const QString &f)
QString	getFilename () const
void	setCurrentLine (qint32 line)
	Set the debugger "execution paused" line (amber bar) and move the caret to that line. Pass <= 0 to clear only the paused-line bar.
void	clearCurrentLineHighlight ()
	Clear the debugger paused-line highlight (caret stripe unchanged).
void	moveCaretToLineStart (qint32 line)
	Move the caret to the start of a line without changing the paused line (e.g. go-to-line).
void	setEditorFont (const QFont &font)
	Apply a monospace font to both editor text and gutter.
void	updateBreakpointMarkers ()
	Refresh breakpoint markers in the gutter area.
void	applyTheme ()
	Re-apply theme colors from the current preference.
QString	luaIdentifierUnderCursor (const QTextCursor &cursor) const
	Return the Lua identifier under the given cursor position, or an empty string if the position is not on an identifier.
QString	watchExpressionForContextMenu (const QPoint &viewportPos) const
	Watch text for the editor context menu: trimmed selection if any, otherwise the Lua identifier at viewportPos (viewport coordinates).

Protected Member Functions
void	resizeEvent (QResizeEvent *event) override
	Update margins whenever Qt reports a size change.
bool	eventFilter (QObject *watched, QEvent *event) override

Detailed Description

Editable code editor supporting gutter breakpoints and highlighting.

Constructor & Destructor Documentation

LuaDebuggerCodeView()

LuaDebuggerCodeView::LuaDebuggerCodeView

(

QWidget *

parent = nullptr

)

Create the code view and configure the line number gutter.

Parameters

parent

Optional parent widget for ownership.

Member Function Documentation

breakpointGutterMenuRequested

void LuaDebuggerCodeView::breakpointGutterMenuRequested ( const QString &  filename, qint32  line, const QPoint &  globalPos  )

signal

Request an Edit / Disable (Enable) / Remove popup for the breakpoint at filename:line, anchored at globalPos.

Emitted in two cases:

1. A plain left-click on the gutter that lands on a "rich" breakpoint (one carrying a condition, hit-count target, or log message). The popup guards those user-typed extras against accidental loss; plain breakpoints keep the original add-or-remove-on-click behaviour and emit breakpointToggled instead.
2. A context-menu gesture (right-click on Win/Linux, Ctrl- click or two-finger trackpad tap on macOS) on any existing breakpoint, regardless of whether it carries extras. The same popup is offered, so the destructive Remove always sits behind an explicit menu choice.

breakpointToggled

void LuaDebuggerCodeView::breakpointToggled ( const QString &  filename, qint32  line, bool  toggleActive  )

signal

Emitted when a breakpoint icon is clicked within the gutter (right margin).

Parameters

toggleActive

If true, the click should enable/disable the breakpoint without removing it (currently mapped to Shift+click); otherwise add or remove on plain click.

lineNumberAreaPaintEvent()

void LuaDebuggerCodeView::lineNumberAreaPaintEvent

(

QPaintEvent *

event

)

Paint the custom gutter that hosts line numbers and breakpoints.

Parameters

event

Exposes the area to repaint.

lineNumberAreaWidth()

qint32 LuaDebuggerCodeView::lineNumberAreaWidth

(

)

Compute the width required for the gutter, including icons.

Returns

Width in device-independent pixels.

luaIdentifierUnderCursor()

QString LuaDebuggerCodeView::luaIdentifierUnderCursor

(

const QTextCursor &

cursor

)

const

Return the Lua identifier under the given cursor position, or an empty string if the position is not on an identifier.

Lua identifiers are [A-Za-z_][A-Za-z0-9_]*. The bracket grammar that the Watch panel accepts (a.b[1], a.b["k"]) is not synthesized here — only the bare identifier at cursor's position is returned, mirroring the "double-click to select word" affordance Qt's text editors offer.
