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
clickCountgives 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.

Implements SoPointingAction.

Referenced by SoPointingAction::dragCancelled().

◆ 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 own 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 status bar (make it short!), this will get 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.

If not, 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.
