Detailed Description

A command to transform a selection of shapes with the same transformation.

Definition at line 18 of file KoShapeTransformCommand.cpp.

Constructor & Destructor Documentation

◆ KoShapeTransformCommand()

KoShapeTransformCommand::KoShapeTransformCommand	(	const QList< KoShape * > &	shapes,
		const QList< QTransform > &	oldState,
		const QList< QTransform > &	newState,
		KUndo2Command *	parent = 0 )

A command to transform a selection of shapes to the new state. Each shape passed has an old state and a new state of transformation passed in.

Parameters

shapes	all the shapes that should be transformed
oldState	the old shapes transformations
newState	the new shapes transformations

    Q_ASSERT(shapes.count() == newState.count());

Member Function Documentation

◆ id()

int KoShapeTransformCommand::id ( ) const

overridevirtual

Returns the ID of this command.

A command ID is used in command compression. It must be an integer unique to this command's class, or -1 if the command doesn't support compression.

If the command supports compression this function must be overridden in the derived class to return the correct ID. The base implementation returns -1.

KUndo2QStack::push() will only try to merge two commands if they have the same ID, and the ID is not -1.

See also: mergeWith(), KUndo2QStack::push()

Reimplemented from KUndo2Command.

Definition at line 68 of file KoShapeTransformCommand.cpp.

{
    return KisCommandUtils::TransformShapeId;
}

References KisCommandUtils::TransformShapeId.

◆ mergeWith()

bool KoShapeTransformCommand::mergeWith ( const KUndo2Command * command )

overridevirtual

Attempts to merge this command with command. Returns true on success; otherwise returns false.

If this function returns true, calling this command's redo() must have the same effect as redoing both this command and command. Similarly, calling this command's undo() must have the same effect as undoing command and this command.

KUndo2QStack will only try to merge two commands if they have the same id, and the id is not -1.

The default implementation returns false.

See also: id() KUndo2QStack::push()

Reimplemented from KUndo2Command.

    const KoShapeTransformCommand *other = dynamic_cast<const KoShapeTransformCommand*>(command);
 
    if (!other ||
        other->d->shapes != d->shapes ||

        return false;
    }
 
    d->newState = other->d->newState;
    return true;

◆ Private()

inline

Definition at line 21 of file KoShapeTransformCommand.cpp.

21: shapes(list) { }

◆ redo()

void KoShapeTransformCommand::redo ( )

overridevirtual

redo the command

Reimplemented from KUndo2Command.

Definition at line 42 of file KoShapeTransformCommand.cpp.

{
    KUndo2Command::redo();
 
    const int shapeCount = d->shapes.count();
    for (int i = 0; i < shapeCount; ++i) {
        KoShape * shape = d->shapes[i];
        const QRectF oldDirtyRect = shape->boundingRect();
        shape->setTransformation(d->newState[i]);
        shape->updateAbsolute(oldDirtyRect | shape->boundingRect());
    }
}

◆ undo()

void KoShapeTransformCommand::undo ( )

overridevirtual

revert the actions done in redo
