Public Member Functions

 DigitizeStateAbstractBase (DigitizeStateContext &context)
 Single constructor.
 
virtual QString activeCurve () const =0
 Name of the active Curve. This can include AXIS_CURVE_NAME.
 
virtual void begin (DigitizeState previousState)=0
 Method that is called at the exact moment a state is entered. More...
 
DigitizeStateContextcontext ()
 Reference to the DigitizeStateContext that contains all the DigitizeStateAbstractBase subclasses, without const.
 
const DigitizeStateContextcontext () const
 Reference to the DigitizeStateContext that contains all the DigitizeStateAbstractBase subclasses, without const.
 
virtual void end ()=0
 Method that is called at the exact moment a state is exited. Typically called just before begin for the next state.
 
void handleContextMenuEvent (const QString &pointIdentifier)
 Handle a right click that was intercepted earlier. This is done in the superclass since it works the same in all states.
 
virtual void handleCurveChange ()=0
 Handle the selection of a new curve. At a minimum, DigitizeStateSegment will generate a new set of Segments.
 
virtual void handleKeyPress (Qt::Key key, bool atLeastOneSelectedItem)=0
 Handle a key press that was intercepted earlier.
 
virtual void handleLeave ()
 Handle leave in case an override cursor is in effect from last QDialog, by resetting the override cursor.
 
virtual void handleMouseMove (QPointF posScreen)=0
 Handle a mouse move. This is part of an experiment to see if augmenting the cursor in Point Match mode is worthwhile.
 
virtual void handleMousePress (QPointF pos)=0
 Handle a mouse press that was intercepted earlier.
 
virtual void handleMouseRelease (QPointF pos)=0
 Handle a mouse release that was intercepted earlier.
 
void handleSetOverrideCursor (const QCursor &cursor)
 Handle the command to set the override cursor.
 
void removeOverrideCursor ()
 Remove the override cursor if it is in use. This is called after a leave event, and prior to displaying a QDialog.
 
void setCursor ()
 Update the cursor according to the current state.
 
virtual QString state () const =0
 State name for debugging.
 
virtual void updateModelDigitizeCurve (const DocumentModelDigitizeCurve &modelDigitizeCurve)=0
 Update the digitize curve settings.
 
virtual void updateModelSegments (const DocumentModelSegments &modelSegments)=0
 Update the segments given the new settings.
 

Protected Member Functions

virtual QCursor cursor () const =0
 Returns the state-specific cursor shape.
 

Detailed Description

Member Function Documentation

virtual void DigitizeStateAbstractBase::begin ( DigitizeState  previousState)
pure virtual

Method that is called at the exact moment a state is entered.

Typically called just after end for the previous state. The previousState value is used by DigitizeStateColorPicker to return to the previous state

Implemented in DigitizeStateColorPicker, DigitizeStatePointMatch, DigitizeStateSegment, DigitizeStateAxis, DigitizeStateCurve, DigitizeStateEmpty, and DigitizeStateSelect.
