Detailed Description

Item delegate for the Breakpoints list Location column (condition / hit count / log message inline editor).

The editor is a single QLineEdit configured per-mode by a small mode-picker combo on the left. A hit-count comparison combo and an "also pause" toggle are embedded as children of the line edit and are shown only for the modes that own them. See the implementation file for the full design rationale.

Constructor & Destructor Documentation

LuaDbgBreakpointConditionDelegate()

LuaDbgBreakpointConditionDelegate::LuaDbgBreakpointConditionDelegate ( LuaDebuggerDialog *  dialog )

explicit

Construct a LuaDbgBreakpointConditionDelegate.

Parameters

dialog

The owning LuaDebuggerDialog, used to coordinate commit and cancel actions with the breakpoint model.

Member Function Documentation

createEditor()

QWidget * LuaDbgBreakpointConditionDelegate::createEditor ( QWidget *  parent, const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

override

Create a QLineEdit editor for a breakpoint condition cell.

Parameters

parent	The parent widget for the editor (the view's viewport).
option	Style options for the cell being edited.
index	The model index of the condition cell being edited.

Returns

A new QLineEdit widget; ownership passes to the view.

eventFilter()

bool LuaDbgBreakpointConditionDelegate::eventFilter ( QObject *  watched, QEvent *  event  )

overrideprotected

Filter key events on the editor to control commit and cancel.

Parameters

watched	The object that received the event (the editor widget).
event	The event to inspect.

Returns

true if the event was consumed; false to let it propagate.

setEditorData()

void LuaDbgBreakpointConditionDelegate::setEditorData ( QWidget *  editor, const QModelIndex &  index  ) const

override

Populate the editor with the cell's current condition string.

Parameters

editor	The QLineEdit created by createEditor().
index	The model index whose data should be loaded.

setModelData()

void LuaDbgBreakpointConditionDelegate::setModelData ( QWidget *  editor, QAbstractItemModel *  model, const QModelIndex &  index  ) const

override

Write the edited condition expression back to the model.

Parameters

editor	The QLineEdit created by createEditor().
model	The breakpoint model to update.
index	The model index of the condition cell being committed.

sizeHint()

QSize LuaDbgBreakpointConditionDelegate::sizeHint ( const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

override

Return the preferred size for a condition cell.

Parameters

option	Style options for the cell.
index	The model index of the cell.

Returns

A QSize with the natural editor height and the base-class width.

updateEditorGeometry()

void LuaDbgBreakpointConditionDelegate::updateEditorGeometry ( QWidget *  editor, const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

override

Position and size the editor to fill the cell rectangle.

Parameters

editor	The QLineEdit to reposition.
option	Style options supplying the cell's bounding rectangle.
index	The model index of the cell being edited (unused here).
