Detailed Description

Implements guideline behavior for GUIDELINE_STATE_DEPLOYED_CONSTANT_R_SELECT_EDIT_APPEARING.

This acts just like GUIDELINE_STATE_DEPLOYED_CONSTANT_R_SELECT_EDIT but is drawn much bigger, then transitions to the other state after a timeout

Member Function Documentation

begin()

void GuidelineStateDeployedConstantRSelectEditAppearing::begin ( )

virtual

Transition into state.

Implements GuidelineStateAbstractBase.

}

doPaint()

bool GuidelineStateDeployedConstantRSelectEditAppearing::doPaint ( ) const

virtual

  return true;
}

end()

void GuidelineStateDeployedConstantRSelectEditAppearing::end ( )

virtual

Reimplemented from GuidelineStateDeployedAbstract.

Definition at line 49 of file GuidelineStateDeployedConstantRSelectEditAppearing.cpp.

{
  LOG4CPP_INFO_S ((*mainCat)) << "GuidelineStateDeployedConstantRSelectEditAppearing::end";
 
  // Cancel timer if active so it does not interrupt the next state
  QObject::disconnect (m_timer, SIGNAL (timeout ()), &context(), SLOT (slotTimeout ()));
}

handleActiveChange()

void GuidelineStateDeployedConstantRSelectEditAppearing::handleActiveChange ( bool active )

virtual

Implements GuidelineStateAbstractBase.

Definition at line 57 of file GuidelineStateDeployedConstantRSelectEditAppearing.cpp.

{
  if (!active) {
    context().requestStateTransition(GUIDELINE_STATE_DEPLOYED_CONSTANT_R_UNSELECT_EDIT);
  }
}

handleGuidelineMode()

void GuidelineStateDeployedConstantRSelectEditAppearing::handleGuidelineMode ( bool visibility, bool locked )

virtual

User toggled Guideline visibility and/or locked mode.

Implements GuidelineStateAbstractBase.

Definition at line 64 of file GuidelineStateDeployedConstantRSelectEditAppearing.cpp.

{
  // Currently visible and not locked
  if (visible && locked) {
    context().requestStateTransition(GUIDELINE_STATE_DEPLOYED_CONSTANT_R_SELECT_LOCK);
  } else if (!visible) {
    context().requestStateTransition(GUIDELINE_STATE_DEPLOYED_CONSTANT_R_SELECT_HIDE);
  }
}

handleHoverEnterEvent()

void GuidelineStateDeployedConstantRSelectEditAppearing::handleHoverEnterEvent ( )

virtual

If transparent then make visible when hover starts.

Implements GuidelineStateAbstractBase.

Definition at line 75 of file GuidelineStateDeployedConstantRSelectEditAppearing.cpp.

{
  context().requestStateTransition(GUIDELINE_STATE_DEPLOYED_CONSTANT_R_SELECT_EDIT_HOVER);
}

handleHoverLeaveEvent()

void GuidelineStateDeployedConstantRSelectEditAppearing::handleHoverLeaveEvent ( )

virtual

If previously transparent before hover enter then make transparent again.

Implements GuidelineStateAbstractBase.

}

handleMousePress()

void GuidelineStateDeployedConstantRSelectEditAppearing::handleMousePress ( const QPointF & posScene )

virtual

At the start of dragging, convert the Guideline into an invisible handle and visible slaved deployed Guideline.

Implements GuidelineStateAbstractBase.

                          GUIDELINE_STATE_DEPLOYED_CONSTANT_R_SELECT_EDIT);
}

handleTimeout()

void GuidelineStateDeployedConstantRSelectEditAppearing::handleTimeout ( )

virtual

Handle timeout from Appearing state.

Reimplemented from GuidelineStateDeployedAbstract.

Definition at line 91 of file GuidelineStateDeployedConstantRSelectEditAppearing.cpp.

{
  context().requestStateTransition (GUIDELINE_STATE_DEPLOYED_CONSTANT_R_SELECT_EDIT);

stateName()

QString GuidelineStateDeployedConstantRSelectEditAppearing::stateName ( ) const

virtual

Name of state as a string for debugging only.

Implements GuidelineStateAbstractBase.
