Detailed Description

A (selectable) object on an IpePage.

Adds selection status and layer to IpeObject.


Member Enumeration Documentation

enum IpePgObject::TSelect
 

Selection status of an object on the page.


Constructor & Destructor Documentation

IpePgObject::IpePgObject TSelect    sel,
int    layer,
IpeObject   obj
[inline, explicit]
 

Constructor takes ownership of object.

IpePgObject::IpePgObject const IpePgObject &    rhs
 

Copy constructor clones object.

IpePgObject::~IpePgObject  
 

Destructor.


Member Function Documentation

IpeObject* IpePgObject::Object   [inline]
 

Return IpeObject.

const IpeObject* IpePgObject::Object   const [inline]
 

Return IpeObject (const version).

TSelect IpePgObject::Select   const [inline]
 

Return selection status.

int IpePgObject::Layer   const [inline]
 

Return layer.

void IpePgObject::SetSelect TSelect    sel [inline]
 

Set selection status.

void IpePgObject::SetLayer int    layer [inline]
 

Set layer.

void IpePgObject::ReplaceObject IpeObject   obj
 

Replace the object.

IpeRect IpePgObject::BBox   const
 

Return a bounding box for the object.

IpePgObject caches the box the first time it is computed.

Make sure you call IpePgObject::Transform instead of IpeObject::SetMatrix, as the latter would not invalidate the bounding box.

void IpePgObject::Transform const IpeMatrix   m
 

Transform the object.

Use this function instead of calling IpeObject::SetMatrix directly, as the latter doesn't invalidate the cached bounding box.

double IpePgObject::Distance const IpeVector   v,
double    bound
const
 

Return distance between object and v.

But may just return bound if the distance is larger. This function uses the cached bounded box, and is faster than calling IpeObject::Distance directly.

void IpePgObject::SnapVtx const IpeVector   mouse,
IpeVector   pos,
double &    bound
const
 

Compute possible vertex snapping position.

Looks only for positions closer than bound. If successful, modifies pos and bound.

void IpePgObject::SnapBnd const IpeVector   mouse,
IpeVector   pos,
double &    bound
const
 

Compute possible boundary snapping position.

Looks only for positions closer than bound. If successful, modifies pos and bound.

void IpePgObject::InvalidateBBox  
 

Invalidate the bounding box (the object is somehow changed).
