Public Member Functions | |
DigitizeStateScale (DigitizeStateContext &context) | |
Single constructor. | |
virtual | ~DigitizeStateScale () |
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. | |
virtual bool | canPaste (const Transformation &transformation, const QSize &viewSize) const |
Return true if there is good data in the clipboard for pasting, and that is compatible with the current state. | |
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 bool | guidelinesAreSelectable () const |
Enable/disable guidelines according to state. | |
virtual void | handleContextMenuEventAxis (CmdMediator *cmdMediator, const QString &pointIdentifier) |
Handle a right click, on an axis point, that was intercepted earlier. | |
virtual void | handleContextMenuEventGraph (CmdMediator *cmdMediator, const QStringList &pointIdentifiers) |
Handle a right click, on a graph point, that was intercepted earlier. | |
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 | updateAfterPointAddition () |
Update graphics attributes after possible new points. This is useful for highlight opacity. | |
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. | |
virtual | ~DigitizeStateAbstractBase () |
DigitizeStateContext & | context () |
Reference to the DigitizeStateContext that contains all the DigitizeStateAbstractBase subclasses, without const. | |
const DigitizeStateContext & | context () const |
Reference to the DigitizeStateContext that contains all the DigitizeStateAbstractBase subclasses, without const. | |
void | setCursor (CmdMediator *cmdMediator) |
Update the cursor according to the current state. |
Additional Inherited Members | |
Protected Member Functions inherited from DigitizeStateAbstractBase | |
bool | canPasteProtected (const Transformation &transformation, const QSize &viewSize) const |
Protected version of canPaste method. Some, but not all, leaf classes use this method. | |
virtual void | handleKeyPressArrow (CmdMediator *cmdMediator, Qt::Key key, bool atLeastOneSelectedItem) |
If the key is an arrow (left, right, up, down) then move currently selected items. | |
QString | moveTextDown () const |
Display text for down arrow. | |
QString | moveTextLeft () const |
Display text for left arrow. | |
QString | moveTextRight () const |
Display text for right arrow. | |
QString | moveTextUp () const |
Display text for up arrow. |
Digitizing state for creating the scale bar.
A scale bar is preferred over an approach using two axis points and DigitizeStateAxis since:
