Member Function Documentation

◆ createCommand()

KUndo2Command * KoPathControlPointMoveStrategy::createCommand ( )

overridevirtual

For interactions that are undo-able this method should be implemented to return such a command. Implementations should return 0 otherwise.

Returns: a command, or 0.

Implements KoInteractionStrategy.

Definition at line 52 of file KoPathControlPointMoveStrategy.cpp.

{
    if (m_intermediateCommand) {
        return new KisCommandUtils::SkipFirstRedoWrapper(m_intermediateCommand.take());
    }
    return nullptr;
}

References m_intermediateCommand.

◆ finishInteraction()

void KoPathControlPointMoveStrategy::finishInteraction ( Qt::KeyboardModifiers modifiers )

overridevirtual

Override to make final changes to the data on the end of an interaction.

Implements KoInteractionStrategy.

Definition at line 47 of file KoPathControlPointMoveStrategy.cpp.

{
    Q_UNUSED(modifiers);
}

◆ handleMouseMove()

void KoPathControlPointMoveStrategy::handleMouseMove	(	const QPointF &	mouseLocation,
		Qt::KeyboardModifiers	modifiers )

overridevirtual

Extending classes should implement this method to update the selectedShapes based on the new mouse position.

Parameters

mouseLocation	the new location in pt
modifiers	OR-ed set of keys pressed.

Implements KoInteractionStrategy.

Definition at line 31 of file KoPathControlPointMoveStrategy.cpp.

    // to save it in document pos and not in shape pos
