virtual void CmdAbstract::cmdRedo ( )

pure virtual

Redo method that is called when QUndoStack is moved one command forward.

Implemented in CmdAddPointAxis, CmdAddPointGraph, CmdAddPointsGraph, CmdCopy, CmdCut, CmdDelete, CmdEditPointAxis, CmdMoveBy, CmdPaste, CmdSelectCoordSystem, CmdSettingsAxesChecker, CmdSettingsColorFilter, CmdSettingsCoords, CmdSettingsCurveAddRemove, CmdSettingsCurveProperties, CmdSettingsDigitizeCurve, CmdSettingsExportFormat, CmdSettingsGeneral, CmdSettingsGridRemoval, CmdSettingsPointMatch, and CmdSettingsSegments.

cmdUndo()

virtual void CmdAbstract::cmdUndo ( )

pure virtual

Undo method that is called when QUndoStack is moved one command backward.

Implemented in CmdAddPointAxis, CmdAddPointGraph, CmdAddPointsGraph, CmdCopy, CmdCut, CmdDelete, CmdEditPointAxis, CmdMoveBy, CmdPaste, CmdSelectCoordSystem, CmdSettingsAxesChecker, CmdSettingsColorFilter, CmdSettingsCoords, CmdSettingsCurveAddRemove, CmdSettingsCurveProperties, CmdSettingsDigitizeCurve, CmdSettingsExportFormat, CmdSettingsGeneral, CmdSettingsGridRemoval, CmdSettingsPointMatch, and CmdSettingsSegments.

document() [1/2]

Document & CmdAbstract::document ( )

protected

Return the Document that this command will modify during redo and undo.

Definition at line 33 of file CmdAbstract.cpp.

document() [2/2]

const Document & CmdAbstract::document ( ) const

protected

Return a const copy of the Document for non redo/undo interaction.

Definition at line 38 of file CmdAbstract.cpp.

mainWindow()

MainWindow & CmdAbstract::mainWindow ( )

protected

Return the MainWindow so it can be updated by this command as a last step.

Definition at line 43 of file CmdAbstract.cpp.

resetSelection()

void CmdAbstract::resetSelection ( const PointIdentifiers &  pointIdentifiersToSelect )

protected

Since the set of selected points has probably changed, changed that set back to the specified set.

This lets the user move selected point(s) repeatedly using arrow keys. Also provides expected behavior when pasting

Definition at line 79 of file CmdAbstract.cpp.

saveXml()

virtual void CmdAbstract::saveXml ( QXmlStreamWriter &  writer ) const

pure virtual

Save commands as xml for later uploading.

Implemented in CmdAddPointAxis, CmdAddPointGraph, CmdAddPointsGraph, CmdCopy, CmdCut, CmdDelete, CmdEditPointAxis, CmdMoveBy, CmdPaste, CmdSelectCoordSystem, CmdSettingsAxesChecker, CmdSettingsColorFilter, CmdSettingsCoords, CmdSettingsCurveAddRemove, CmdSettingsCurveProperties, CmdSettingsDigitizeCurve, CmdSettingsExportFormat, CmdSettingsGeneral, CmdSettingsGridRemoval, CmdSettingsPointMatch, and CmdSettingsSegments.
