virtual void cmdRedo()
Redo method that is called when QUndoStack is moved one command forward.
virtual void cmdUndo()
Undo method that is called when QUndoStack is moved one command backward.
Wrapper around QUndoCommand. This simplifies the more complicated feature set of QUndoCommand.
Definition: CmdAbstract.h:19
virtual void saveXml(QXmlStreamWriter &writer) const
Save entire model as xml into stream.
void saveOrCheckPostCommandDocumentStateHash(const Document &document)
Save, when called the first time, a hash value representing the state of the Document.
void saveOrCheckPreCommandDocumentStateHash(const Document &document)
Save, when called the first time, a hash value representing the state of the Document.
virtual void loadXml(QXmlStreamReader &reader)
Load model from serialized xml.
MainWindow & mainWindow()
Return the MainWindow so it can be updated by this command as a last step.
Definition: CmdAbstract.cpp:45
virtual void saveXml(QXmlStreamWriter &writer) const
Save commands as xml for later uploading.
void updateAfterCommand()
See GraphicsScene::updateAfterCommand.

void updateSettingsAxesChecker(const DocumentModelAxesChecker &modelAxesChecker)
Update with new axes indicator properties.
CmdSettingsAxesChecker(MainWindow &mainWindow, Document &document, const DocumentModelAxesChecker &modelAxesCheckerBefore, const DocumentModelAxesChecker &modelAxesCheckerAfter)
Constructor for normal creation.
Model for DlgSettingsAxesChecker and CmdSettingsAxesChecker.
Document & document()
Return the Document that this command will modify during redo and undo.
Definition: CmdAbstract.cpp:35
Main window consisting of menu, graphics scene, status bar and optional toolbars as a Single Document...
