CmdAddPointAxis(MainWindow &mainWindow, Document &document, const QPointF &posScreen, const QPointF &posGraph, double ordinal, bool isXOnly)
Constructor for normal creation.
virtual void cmdUndo()
Undo method that is called when QUndoStack is moved one command backward.
void removePointAxis(const QString &identifier)
Perform the opposite of addPointAxis.
Definition: Document.cpp:727

Definition: CmdAbstract.h:18
virtual void saveXml(QXmlStreamWriter &writer) const
Save commands as xml for later uploading.
virtual void cmdRedo()
Redo method that is called when QUndoStack is moved one command forward.
MainWindow & mainWindow()
Return the MainWindow so it can be updated by this command as a last step.
Definition: CmdAbstract.cpp:43
void updateAfterCommand()
See GraphicsScene::updateAfterCommand.
Storage of one imported image and the data attached to that image.
Definition: Document.h:40
void addPointAxisWithGeneratedIdentifier(const QPointF &posScreen, const QPointF &posGraph, QString &identifier, double ordinal, bool isXOnly)
Add a single axis point with a generated point identifier.
Definition: Document.cpp:154
Document & document()
Return the Document that this command will modify during redo and undo.
Definition: CmdAbstract.cpp:33
Main window consisting of menu, graphics scene, status bar and optional toolbars as a Single Document...
Definition: MainWindow.h:77
void updatePointOrdinals(const Transformation &transformation)
Update point ordinals after point addition/removal or dragging.
Definition: Document.cpp:903
