Member Function Documentation

createCommand()

KUndo2Command * ShapeGradientEditStrategy::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 79 of file ShapeGradientEditStrategy.cpp.

{
    return m_d->intermediateCommand ?
        new KisCommandUtils::SkipFirstRedoWrapper(m_d->intermediateCommand.take()) :
        nullptr;
}

References m_d.

finishInteraction()

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

overridevirtual

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

Implements KoInteractionStrategy.

Definition at line 86 of file ShapeGradientEditStrategy.cpp.

{
    Q_UNUSED(modifiers);
    tool()->canvas()->snapGuide()->reset();
}

References KoToolBase::canvas(), KoSnapGuide::reset(), KoCanvasBase::snapGuide, and KoInteractionStrategy::tool().

handleMouseMove()

void ShapeGradientEditStrategy::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 68 of file ShapeGradientEditStrategy.cpp.

{
    const QPointF snappedPosition = tool()->canvas()->snapGuide()->snap(mouseLocation, m_d->initialOffset, modifiers);
    const QPointF diff = snappedPosition - m_d->previous;
    m_d->previous = snappedPosition;
 
    KisCommandUtils::redoAndMergeIntoAccumulatingCommand(
        m_d->gradientHandles.moveGradientHandle(m_d->handleType, diff),
        m_d->intermediateCommand);
}

References KoToolBase::canvas(), m_d, KisCommandUtils::redoAndMergeIntoAccumulatingCommand(), KoSnapGuide::snap(), KoCanvasBase::snapGuide, and KoInteractionStrategy::tool().

paint()

void ShapeGradientEditStrategy::paint ( QPainter & painter, const KoViewConverter & converter )

overridevirtual

Reimplement this if the action needs to draw a "blob" on the canvas; that is, a transient decoration like a rubber band.

Reimplemented from KoInteractionStrategy.

Definition at line 92 of file ShapeGradientEditStrategy.cpp.

{
    Q_UNUSED(painter);
    Q_UNUSED(converter);
