Member Function Documentation

redo()

void KisImageResizeCommand::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 28 of file kis_image_resize_command.cpp.

{
    KisImageSP image = m_image.toStrongRef();
    if (!image) {
        return;
    }
    image->setSize(m_sizeAfter);
}

References m_image, m_sizeAfter, KisImage::setSize(), and KisWeakSharedPtr< T >::toStrongRef().

undo()

void KisImageResizeCommand::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.
