Public Member Functions

 DigitizeStateEmpty (DigitizeStateContext &context)
 Single constructor.
 
virtual QString activeCurve () const
 Name of the active Curve. This can include AXIS_CURVE_NAME.
 
virtual void begin (CmdMediator *cmdMediator, DigitizeState previousState)
 Method that is called at the exact moment a state is entered. More...
 
virtual QCursor cursor (CmdMediator *cmdMediator) const
 Returns the state-specific cursor shape.
 
virtual void end ()
 Method that is called at the exact moment a state is exited. Typically called just before begin for the next state.
 
virtual void handleCurveChange (CmdMediator *cmdMediator)
 Handle the selection of a new curve. At a minimum, DigitizeStateSegment will generate a new set of Segments.
 
virtual void handleKeyPress (CmdMediator *cmdMediator, Qt::Key key, bool atLeastOneSelectedItem)
 Handle a key press that was intercepted earlier.
 
virtual void handleMouseMove (CmdMediator *cmdMediator, QPointF posScreen)
 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 (CmdMediator *cmdMediator, QPointF posScreen)
 Handle a mouse press that was intercepted earlier.
 
virtual void handleMouseRelease (CmdMediator *cmdMediator, QPointF posScreen)
 Handle a mouse release that was intercepted earlier.
 
virtual QString state () const
 State name for debugging.
 
virtual void updateModelDigitizeCurve (CmdMediator *cmdMediator, const DocumentModelDigitizeCurve &modelDigitizeCurve)
 Update the digitize curve settings.
 
virtual void updateModelSegments (const DocumentModelSegments &modelSegments)
 Update the segments given the new settings.
 
- Public Member Functions inherited from DigitizeStateAbstractBase
 DigitizeStateAbstractBase (DigitizeStateContext &context)
 Single constructor.
 
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.
 
void handleContextMenuEvent (CmdMediator *cmdMediator, 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 handleLeave (CmdMediator *cmdMediator)
 Handle leave in case an override cursor is in effect from last QDialog, by resetting the override cursor.
 
void handleSetOverrideCursor (CmdMediator *cmdMediator, 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 (CmdMediator *cmdMediator)
 Update the cursor according to the current state.

Member Function Documentation

void DigitizeStateEmpty::begin ( CmdMediator cmdMediator,
DigitizeState  previousState 
)
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

Implements DigitizeStateAbstractBase.
