Detailed Description

SoOffsetPointingAction is an internal proxy class that helps controlling SoOffsetActions through a SoPointingAction

Definition at line 21 of file SoOffsetPointingAction.h.

Constructor & Destructor Documentation

◆ SoOffsetPointingAction()

SoOffsetPointingAction::SoOffsetPointingAction ( SoOffsetAction * offsetAction )

Standard constructor.

Member Function Documentation

◆ dragMoveTo()

void SoOffsetPointingAction::dragMoveTo ( const SoPointerPosition & pos )

overridevirtual

Continues the drag to given device position.

Implements SoPointingAction.

◆ endPress()

SoPointingAction * SoOffsetPointingAction::endPress ( int clickCount )

overridevirtual

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. This is, 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 than zero, you will not have received any dragMoveTo calls if wantsImmediateDragUpdates returns false.

Implements SoPointingAction.

References SoPointingAction::SoPointingAction().

◆ getCurrentCursor()

int SoOffsetPointingAction::getCurrentCursor ( SoViewerProxy * ) const

overridevirtual

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 custom cursors when this method is called (see header file SoViewerProxy.h for instructions).

Reimplemented from SoPointingAction.

◆ getCurrentStatusMessage()

std::string SoOffsetPointingAction::getCurrentStatusMessage ( ) const

overridevirtual

Returns a status message for display in the status bar of MeVisLab (make it short!), this is called at same time as getCurrentCursor.

Note: This is currently unused.

Reimplemented from SoPointingAction.

◆ isEnabled()

bool SoOffsetPointingAction::isEnabled ( ) const

overridevirtual

Returns the enabled status of this interaction - if this returns false, the action is not selectable (but if a mouse action has already been started, it will not be aborted if this returns false).

Reimplemented from SoInteraction.

◆ isSensitiveAt()

bool SoOffsetPointingAction::isSensitiveAt ( const SoPointerPosition & pos )

inlineoverridevirtual

Returns true if the gesture is startable at the given device position. Otherwise, a mouse click will be handed to another SoPointingAction and the cursor shape of this action is ignored!

Note: Only called if isPositionSensitive() returns true.

Implements SoPointingAction.

Definition at line 31 of file SoOffsetPointingAction.h.

◆ proxiedOffsetAction()

SoOffsetAction * SoOffsetPointingAction::proxiedOffsetAction ( ) const

inlineoverrideprotectedvirtual

Reimplemented from SoPointingAction.

Definition at line 41 of file SoOffsetPointingAction.h.

◆ setEnabled()

void SoOffsetPointingAction::setEnabled ( bool enabled )

overridevirtual

Sets the enabled status of this interaction.

Reimplemented from SoInteraction.

◆ setOffsetParameters()

void SoOffsetPointingAction::setOffsetParameters	(	double	sensitivityX,
		double	sensitivityY,
		bool	swapAxes )

◆ startPressAt()

void SoOffsetPointingAction::startPressAt ( const SoPointerPosition & pos )

overridevirtual

Starts a drag at given device position. It is guaranteed that this will be followed by (possibly) dragMoveTo calls and either an endPress or dragCancelled call.

Implements SoPointingAction.
