Member Function Documentation

void AddLayer::processInternal ( )

protectedvirtual

This function gets called when an operation starts and when the document is locked for you so you can do your work

Implements lc::operation::DocumentOperation.

Definition at line 15 of file layerops.cpp.

                               {
    document()->addDocumentMetaType(_layer);
}

void AddLayer::redo ( ) const

virtual

Redo a given operation.

This can get called if we want to redo a operation. Redo is usually called after an undo operation. If in the undo operation entities where removed, it needs to get added again. it doesn't have to do any re.calculation but just remember what entities have been added or removed.

Implements lc::operation::Undoable.

Definition at line 23 of file layerops.cpp.

                          {
    document()->addDocumentMetaType(_layer);
}

void AddLayer::undo ( ) const

virtual

Undo a given operation.

For any operation that means for example when it added entities to the document it now needs to remove all created entities on the document. When the operation added a layer or block, it will call functions to remove that block

Implements lc::operation::Undoable.

Definition at line 19 of file layerops.cpp.

                          {
    document()->removeDocumentMetaType(_layer);
