SoPointingAction *	endPress (int) override
	Ends the drag at last device position.

int	getCurrentCursor (SoViewerProxy *) const override
	Returns the cursor ID to display for this action, as defined in SoViewerProxy.h - this gets (at least) called after setMode(), isSensitiveAt(), startPressAt(), dragMoveTo(), and endPress().

Public Member Functions inherited from SoPointingAction
	SoPointingAction (SoInteractionOwner *owner, std::string id, bool positionSensitive=true)
	Standard constructor.

virtual bool	isPositionSensitive () const
	Position sensitive actions can only start at positions where isSensitiveAt() return true.

void	clearTriggers ()
	remove all triggers

void	setTrigger (int triggerMask, int ignoreMask=0)
	Sets the (only) default modifier/button mask for triggering this action.

void	setTrigger (const Trigger &trigger)
	Same with Trigger object.

void	addTrigger (const Trigger &trigger)
	Adds another default modifier/button mask as trigger.

TriggerList	getTriggers () const
	Returns the list of default modifier/button mask combinations set for this action.

virtual bool	triggersAction (int mask)
	Returns whether the given modifier/button combination activates this action according to the default bindings.

virtual int	getNumModes () const
	Returns the number of different modes this action has - modes can be changed during drag and handle drag restrictions or drag result.

virtual std::string	getCurrentStatusMessage () const
	Returns a status message for display in status bar (make it short!), this will get called at same time as getCurrentCursor.

virtual void	setMode (int)
	This gets called if the mode was changed and before startPressAt is called.

virtual void	setHighlightAt (const SoPointerPosition &)
	This method is called so that highlighting of objects under the mouse cursor can occur.

virtual void	unsetHighlight ()
	Remove any highlighting if this method is called.

virtual void	dragCancelled ()
	This is called if the current drag operation is cancelled, e.g.

virtual bool	wantsMouseOverUpdates ()
	Override this to return true if this action should get location updates directly before rendering, so it can update its status.

void	grabReleased ()
	Call this to release an interaction grab that has been established by the return value of endPress(), e.g., because it was aborted through a SoCommandAction.

virtual void	releaseGrab (StopMode)
	This will be called by the controller if you should release the grab established by endPress.

virtual bool	wantsImmediateDragUpdates ()
	Let this method return false if you don't want dragMoveTo to be called until it is clear that the interaction will not be handled as a click (endPress will be called with a clickCount greater zero).

Public Member Functions inherited from SoInteraction
	SoInteraction (InteractionType type, SoInteractionOwner *owner, const std::string &id, bool registerWithOwner=true)
	Standard constructor.

virtual	~SoInteraction ()
	Virtual destructor.

SoInteractionOwner *	getOwner () const

virtual bool	isEnabled () const

virtual void	setEnabled (bool enabled)
	Sets the enabled status of this interaction.

std::string	getID () const

void	setID (const std::string &id)
	Sets the id of this interaction.

std::string	getFullID () const
	Returns the ID string consisting of the id of the provider and this action's id, separated by '.

InteractionType	getInteractionType () const
	Get type of interaction object.

template<class T >
bool	isOfType () const
	Convenience method for checking type.

int	getMenuPriority () const

void	setMenuPriority (int priority)
	Sets the priority value for ordered display in menus/tool boxes.

virtual std::string	getUserName () const

virtual void	setUserName (const std::string &name)
	Sets the user name of this interaction entry.

virtual std::string	getIconFile () const

virtual void	setIconFile (const std::string &file)
	Sets the filename of an icon used for this interaction entry.

virtual std::string	getDescription () const

virtual void	setDescription (const std::string &descr)
	Sets the description for user help.

virtual void	ref ()

virtual void	unref ()

int	getStateVersion () const

void	touch ()
	Increments the version number of attribute state to mark attribute changes.

Member Function Documentation

◆ dragMoveTo()

void SoCSODrawOnSurfaceDrawAction::dragMoveTo ( const SoPointerPosition & pos )

inlineoverridevirtual

Continues the drag to given device position.

Implements SoPointingAction.

Definition at line 67 of file SoCSODrawOnSurfaceActions.h.

References dragMoveTo(), SoInteraction::getOwner(), and isInViewportRegion().

Referenced by dragMoveTo().

◆ endPress()

SoPointingAction * SoCSODrawOnSurfaceDrawAction::endPress ( int clickCount )

inlineoverridevirtual

Ends the drag at last device position.

If this method returns a non-NULL SoPointingAction, the pointing device is restricted to this SoPointingAction until releaseGrab() is called or another call to endPress returns NULL. This is useful if the end user is required to click at at least one other position.

Note that locking of the returned action breaks down if the same node is used in several viewers, since each viewer usually has its own interaction controller that manages locked actions on its own.

Parameters

clickCount gives the number of clicks at the last start position. I.e. for a normal drag it is 0, for a single click it is 1, for a double click it is 2 and for a triple click it is 3. Note that for a clickCount greater zero you will not have received any dragMoveTo calls if wantsImmediateDragUpdates returns false.

◆ getCurrentCursor()

int SoCSODrawOnSurfaceDrawAction::getCurrentCursor ( SoViewerProxy * ) const

inlineoverridevirtual

Returns the cursor ID to display for this action, as defined in SoViewerProxy.h - this gets (at least) called after setMode(), isSensitiveAt(), startPressAt(), dragMoveTo(), and endPress().

The SoViewerProxy pointer is provided so one can define own cursors when this method is called (see header file SoViewerProxy.h for instructions).
