Member Function Documentation

LineData AbstractLineImp::data

(

)

const

Get the LineData for this AbstractLineImp.

Definition at line 359 of file line_imp.cc.

bool AbstractLineImp::equals ( const ObjectImp &  rhs ) const

virtual

Returns true if this ObjectImp is equal to rhs.

This function checks whether rhs is of the same ObjectImp type, and whether it contains the same data as this ObjectImp.

It is used e.g. by the KigCommand stuff to see what the user has changed during a move.

Implements ObjectImp.

Definition at line 514 of file line_imp.cc.

const QString AbstractLineImp::equationString

(

)

const

Get a string containing the equation of this line in the form "y = a * x + b ".

Definition at line 241 of file line_imp.cc.

const char * AbstractLineImp::iconForProperty ( int  which ) const

virtual

Reimplemented from ObjectImp.

Reimplemented in RayImp, and SegmentImp.

Definition at line 61 of file line_imp.cc.

const ObjectImpType * AbstractLineImp::impRequirementForProperty ( int  which ) const

virtual

Reimplemented from ObjectImp.

Reimplemented in RayImp, and SegmentImp.

Definition at line 54 of file line_imp.cc.

bool AbstractLineImp::inRect ( const Rect &  r, int  width, const KigWidget &  w  ) const

virtual

Implements ObjectImp.

Definition at line 44 of file line_imp.cc.

bool AbstractLineImp::isPropertyDefinedOnOrThroughThisImp ( int  which ) const

virtual

Reimplemented from ObjectImp.

Definition at line 624 of file line_imp.cc.

int AbstractLineImp::numberOfProperties ( ) const

virtual

Reimplemented from ObjectImp.

Reimplemented in RayImp, and SegmentImp.

Definition at line 49 of file line_imp.cc.

const QByteArrayList AbstractLineImp::properties ( ) const

virtual

Reimplemented from ObjectImp.

Reimplemented in RayImp, and SegmentImp.

Definition at line 94 of file line_imp.cc.

const QByteArrayList AbstractLineImp::propertiesInternalNames ( ) const

virtual

Reimplemented from ObjectImp.

Reimplemented in RayImp, and SegmentImp.

Definition at line 85 of file line_imp.cc.

ObjectImp * AbstractLineImp::property ( int  which, const KigDocument &  d  ) const

virtual

Reimplemented from ObjectImp.

Reimplemented in RayImp, and SegmentImp.

Definition at line 73 of file line_imp.cc.

double AbstractLineImp::slope

(

)

const

Get the slope of this AbstractLineImp.

For a line through points a( xa, ya ) and b ( xb, yb ), this means the value ( yb - ya ) / ( xb - xa ).

Definition at line 235 of file line_imp.cc.

const ObjectImpType * AbstractLineImp::stype ( )

static

Returns the ObjectImpType representing the AbstractLineImp type.

Definition at line 520 of file line_imp.cc.
