Member Function Documentation

◆ mergeWith()

bool KisChangeCloneLayersCommand::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.

Definition at line 48 of file KisChangeCloneLayersCommand.cpp.

{
    const KisChangeCloneLayersCommand *other = dynamic_cast<const KisChangeCloneLayersCommand *>(command);
 
    if (other && d->cloneLayers == other->d->cloneLayers) {
        d->newSource = other->d->newSource;
        return true;
    }
 
    return false;
}

◆ redo()

void KisChangeCloneLayersCommand::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 30 of file KisChangeCloneLayersCommand.cpp.

{
    Q_FOREACH (KisCloneLayerSP layer, d->cloneLayers) {
        layer->setCopyFrom(d->newSource);
        layer->setDirty();
    }
}

References d.

◆ undo()

void KisChangeCloneLayersCommand::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.

See also: redo()

Reimplemented from KUndo2Command.
