Detailed Description

Centralised keyboard-shortcut dispatcher for the Lua debugger dialog's eventFilter().

The debugger dialog observes key events delivered to any descendant widget so it can:

• Reserve shortcuts that overlap main-window actions before Qt dispatches them to the global QShortcutMap (see reserveShortcutOverride).
• Route subsequent KeyPress events to the right consumer: breakpoint deletion in the breakpoints tree, "toggle breakpoint" and "run to line" inside a focused code view, Esc / Ctrl+Q handling, and finally fall through to the dialog's own QActions for shortcuts that share a sequence with main-window actions (Ctrl+F / Ctrl+S / Ctrl+G / Ctrl+R / Ctrl+W).

Lifetime: owned by the dialog; non-owning pointers to the dialog and its Ui struct (and the breakpoints tree view) are passed via attach() once the setupUi() pass has finished.

Member Function Documentation

handleKeyPress()

bool LuaDebuggerKeyRouter::handleKeyPress	(	QObject *	obj,
		const QKeyEvent *	ke
	)

Handle a QEvent::KeyPress delivered to the debugger UI.

Returns

true if the event has been consumed (caller's eventFilter should return true); false to fall through to QDialog::eventFilter.

reserveShortcutOverride()

bool LuaDebuggerKeyRouter::reserveShortcutOverride

(

const QKeyEvent *

ke

)

const

Pre-empt a debugger-owned shortcut on QEvent::ShortcutOverride.

Returns

true if ke matches a shortcut the dialog wants to claim from the main window; the caller should accept() the event and return false from its eventFilter so Qt re-delivers the same key as a KeyPress to this dialog.
