Member Function Documentation

◆ redo()

void KisImageChangeLayersCommand::redo ( )

overridevirtual

Applies a change to the document. This function must be implemented in the derived class. Calling KUndo2QStack::push(), KUndo2QStack::undo() or KUndo2QStack::redo() from this function leads to undefined behavior.

The default implementation calls redo() on all child commands.

See also: undo()

Reimplemented from KUndo2Command.

Definition at line 22 of file kis_image_change_layers_command.cpp.

{
    KisImageSP image = m_image.toStrongRef();
    if (image) {
        image->setRootLayer(static_cast<KisGroupLayer*>(m_newRootLayer.data()));
        image->refreshGraphAsync();
        image->notifyLayersChanged();
    }
}

References KisSharedPtr< T >::data(), KisImageCommand::m_image, m_newRootLayer, KisImage::notifyLayersChanged(), KisImage::refreshGraphAsync(), KisImage::setRootLayer(), and KisWeakSharedPtr< T >::toStrongRef().

◆ undo()

void KisImageChangeLayersCommand::undo ( )

overridevirtual

Reverts a change to the document. After undo() is called, the state of the document should be the same as before redo() was called. This function must be implemented in the derived class. Calling KUndo2QStack::push(), KUndo2QStack::undo() or KUndo2QStack::redo() from this function leads to undefined behavior.

The default implementation calls undo() on all child commands in reverse order.
