Storage of one imported image and the data attached to that image.
Definition: Document.h:40
virtual void saveXml(QXmlStreamWriter &writer) const
Save entire model as xml into stream.
Model for DlgSettingsSegments and CmdSettingsSegments.
virtual void cmdUndo()
Undo method that is called when QUndoStack is moved one command backward.
void updateSettingsSegments(const DocumentModelSegments &modelSegments)
Update with new segments properties.
Main window consisting of menu, graphics scene, status bar and optional toolbars as a Single Document...
