Member Function Documentation

◆ id()

int RectangleShapeConfigCommand::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 59 of file RectangleShapeConfigCommand.cpp.

{
    return KisCommandUtils::ChangeRectangleShapeId;
}

References KisCommandUtils::ChangeRectangleShapeId.

◆ mergeWith()

bool RectangleShapeConfigCommand::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.

Reimplemented from KUndo2Command.

{
    const RectangleShapeConfigCommand *other = dynamic_cast<const RectangleShapeConfigCommand*>(command);
 
    if (!other || other->m_rectangle != m_rectangle) {
        return false;
    }
 
    m_newCornerRadiusX = other->m_newCornerRadiusX;
    m_newCornerRadiusY = other->m_newCornerRadiusY;
 
    return true;
}

References m_newCornerRadiusX, m_newCornerRadiusY, and m_rectangle.

◆ redo()

void RectangleShapeConfigCommand::redo ( )

overridevirtual

redo the command

Reimplemented from KUndo2Command.

Definition at line 27 of file RectangleShapeConfigCommand.cpp.

{
    KUndo2Command::redo();
 
    m_rectangle->update();
 
    if (m_oldCornerRadiusX != m_newCornerRadiusX) {
        m_rectangle->setCornerRadiusX(m_newCornerRadiusX);
    }
    if (m_oldCornerRadiusY != m_newCornerRadiusY) {
        m_rectangle->setCornerRadiusY(m_newCornerRadiusY);
    }
 
    m_rectangle->update();
}

◆ undo()

void RectangleShapeConfigCommand::undo ( )

overridevirtual

revert the actions done in redo

Reimplemented from KUndo2Command.

Definition at line 43 of file RectangleShapeConfigCommand.cpp.

    KUndo2Command::undo();
