Inheritance diagram for Inkscape::UI::Tools::MarkerTool:

Public Member Functions
	MarkerTool (SPDesktop *desktop)

	~MarkerTool () override

void	selection_changed (Inkscape::Selection *selection)

bool	root_handler (CanvasEvent const &event) override

Public Member Functions inherited from Inkscape::UI::Tools::ToolBase
	ToolBase (SPDesktop *desktop, std::string &&prefs_path, std::string &&cursor_filename, bool uses_snap=true)

virtual	~ToolBase ()

virtual void	set (Preferences::Entry const &val)
	Called by our pref_observer if a preference has been changed.

virtual bool	item_handler (SPItem *item, CanvasEvent const &event)
	Handles item specific events.

virtual void	menu_popup (CanvasEvent const &event, SPObject *obj=nullptr)
	Create popup menu and tell Gtk to show it.

virtual bool	can_undo (bool redo=false)

virtual bool	is_ready () const

virtual void	switching_away (std::string const &new_tool)

std::string const &	getPrefsPath () const

void	enableSelectionCue (bool enable=true)
	Enables/disables the ToolBase's SelCue.

MessageContext *	defaultMessageContext () const

SPDesktop *	getDesktop () const

SPGroup *	currentLayer () const

void	set_last_active_tool (Glib::ustring last_tool)

const Glib::ustring &	get_last_active_tool () const

bool	start_root_handler (CanvasEvent const &event)
	Handles snapping events for all tools and then passes to tool_root_handler.

bool	tool_root_handler (CanvasEvent const &event)
	Calls the right tool's event handler, depending on the selected tool and state.

bool	start_item_handler (SPItem *item, CanvasEvent const &event)
	Starts handling item snapping and pass to virtual_item_handler afterwards.

bool	virtual_item_handler (SPItem *item, CanvasEvent const &event)

bool	is_panning () const
	True if we're panning with any method (space bar, middle-mouse, right-mouse+Ctrl)

bool	is_space_panning () const
	True if we're panning with the space bar.

void	snap_delay_handler (gpointer item, gpointer item2, MotionEvent const &event, DelayedSnapEvent::Origin origin)
	Analyses the current event, calculates the mouse speed, turns snapping off (temporarily) if the mouse speed is above a threshold, and stores the current event such that it can be re-triggered when needed (re-triggering is controlled by a timeout).

void	process_delayed_snap_event ()
	When the delayed snap event timer expires, this method will be called and will re-inject the last motion event in an appropriate place, with snapping being turned on again.

void	discard_delayed_snap_event ()
	If a delayed snap event has been scheduled, this function will cancel it.

void	set_cursor (std::string filename)
	Sets the current cursor to the given filename.

void	use_cursor (Glib::RefPtr< Gdk::Cursor > cursor)
	Set the cursor to this specific one, don't remember it.

Glib::RefPtr< Gdk::Cursor >	get_cursor (Gtk::Widget &widget, std::string const &filename) const
	Returns the Gdk Cursor for the given filename.

void	use_tool_cursor ()
	Uses the saved cursor, based on the saved filename.

void	enableGrDrag (bool enable=true)

bool	deleteSelectedDrag (bool just_one)
	Delete a selected GrDrag point.

bool	hasGradientDrag () const
	Return true if there is a gradient drag.

void	setup_for_drag_start (ButtonPressEvent const &ev)

void	saveDragOrigin (Geom::Point const &pos)

bool	checkDragMoved (Geom::Point const &pos)
	Analyse the current position and return true once it has moved farther than tolerance from the drag origin (indicating they intend to move the object, not click).

	Grab events from the Canvas Catchall.

void	ungrabCanvasEvents ()
	Ungrab events from the Canvas Catchall.
