VSubpath Class Reference

#include <vpath.h>

Inheritance diagram for VSubpath:

VObject List of all members.

Detailed Description

VSubpath provides a sophisticated list of VSegment.

Noted: it also may contain segments which are marked "deleted". If you are not interested in those undo/redo housholding data, please always use a VSubpathIterator to access segments.

Member Function Documentation

bool VSubpath::pointIsInside ( const KoPoint &  p  )  const

Returns true if point p is located inside the path.

The winding number test is used.

Definition at line 416 of file vpath.cc.

bool VSubpath::intersects ( const VSegment &  segment  )  const

Returns true if the segment intersects this path.

Definition at line 562 of file vpath.cc.

bool VSubpath::counterClockwise (  )  const

Returns false if segmentlist is oriented clockwise.

Definition at line 590 of file vpath.cc.

void VSubpath::revert (  ) 

Reverts the winding orientation.

Definition at line 650 of file vpath.cc.

bool VSubpath::isEmpty (  )  const [inline]

Returns true if the current path is "emtpy".

That means that it has zero or just one ( == "begin") segment.

Definition at line 100 of file vpath.h.

const KoRect & VSubpath::boundingBox (  )  const [virtual]

Calculates the tightest bounding box around the object.

Returns:
the bounding box.

Reimplemented from VObject.

Definition at line 674 of file vpath.cc.

virtual void VSubpath::save ( QDomElement &   )  const [inline, virtual]

Save this object's state to xml.

Parameters:
element the DOM element to which the attributes are saved

Reimplemented from VObject.

Definition at line 109 of file vpath.h.

void VSubpath::load ( const QDomElement &  element  )  [virtual]

Load this object's state from xml and initialize this object accordingly.

Parameters:
element the DOM element from which the attributes are read

Reimplemented from VObject.

Definition at line 751 of file vpath.cc.

VSubpath * VSubpath::clone (  )  const [virtual]

Create an exact copy of this object.

Returns:
the exact object copy

Implements VObject.

Definition at line 698 of file vpath.cc.

void VSubpath::accept ( VVisitor &  visitor  )  [virtual]

Accept a VVisitor.

Reimplemented from VObject.

Definition at line 775 of file vpath.cc.
