Member Function Documentation

◆ id()

int KoShapeResizeCommand::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 112 of file KoShapeResizeCommand.cpp.

{
    return KisCommandUtils::ResizeShapeId;
}

References KisCommandUtils::ResizeShapeId.

◆ mergeWith()

bool KoShapeResizeCommand::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.
