Member Function Documentation

cancelInteraction()

void SvgMoveTextStrategy::cancelInteraction ( )

overridevirtual

This method will undo frames based interactions by calling createCommand() and unexecuting that.

Reimplemented from KoInteractionStrategy.

Definition at line 53 of file SvgMoveTextStrategy.cpp.

{
    SvgMoveTextCommand(m_shape, m_finalPosition, m_initialPosition).undo();
    tool()->repaintDecorations();
}

References m_finalPosition, m_initialPosition, m_shape, KoToolBase::repaintDecorations(), KoInteractionStrategy::tool(), and SvgMoveTextCommand::undo().

createCommand()

KUndo2Command * SvgMoveTextStrategy::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 44 of file SvgMoveTextStrategy.cpp.

{
    tool()->canvas()->snapGuide()->reset();
    if (KisAlgebra2D::fuzzyPointCompare(m_initialPosition, m_finalPosition)) {
        return nullptr;
    }
    return new SvgMoveTextCommand(m_shape, m_finalPosition, m_initialPosition);
}

References KoToolBase::canvas(), KisAlgebra2D::fuzzyPointCompare(), m_finalPosition, m_initialPosition, m_shape, KoSnapGuide::reset(), KoCanvasBase::snapGuide, and KoInteractionStrategy::tool().

finishInteraction()

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

overridevirtual

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

Implements KoInteractionStrategy.

Definition at line 59 of file SvgMoveTextStrategy.cpp.

{
}

handleMouseMove()

void SvgMoveTextStrategy::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 29 of file SvgMoveTextStrategy.cpp.

{
    const QPointF delta = mouseLocation - m_dragStart;
 
    if (modifiers & Qt::ShiftModifier) {
        m_finalPosition = m_initialPosition+ snapToClosestAxis(delta);
    } else {
        m_finalPosition =
            tool()->canvas()->snapGuide()->snap(m_initialPosition + m_anchorOffset + delta, modifiers) - m_anchorOffset;
    }
 
    SvgMoveTextCommand(m_shape, m_finalPosition, m_initialPosition).redo();
    tool()->repaintDecorations();
