Member Function Documentation

void __fastcall TLine::_drawCross (  TCanvas *    c, TColor    col, int    x, int    y )  [private]

Draws a endpoint of an unselected line.

void __fastcall TLine::_drawMarker (  TCanvas *    c, TColor    col, int    x, int    y, int    width )  [private]

Draws a marker, which should show that the line (or point) is selected.

void __fastcall TLine::drawTo (  TPaintBox *    pb )

Draw the line to the TPaintBox pb.

int __fastcall TLine::getEndX (  TPaintBox *    pb )

Returns the end points X in TPaintBox coordinates.

int __fastcall TLine::getEndY (  TPaintBox *    pb )

Returns the end points Y in TPaintBox coordinates.

float __fastcall TLine::getSlope (  TPaintBox *    pb )

Get the line slope in TPaintBox coordinates.

int __fastcall TLine::getStartX (  TPaintBox *    pb )

Returns the start points X in TPaintBox coordinates.

int __fastcall TLine::getStartY (  TPaintBox *    pb )

Returns the start points Y in TPaintBox coordinates.

bool __fastcall TLine::highSlope (  TPaintBox *    pb )

Is slope in TPaintBox coordinates greater than 1.0 .

bool __fastcall TLine::isNear (  TPaintBox *    pb, int    x, int    y )

Returns true if the distance to the point (x,y) is smaler than DEF_DIST.

const TLine& TLine::operator= (  const TLine &    l )  [inline]

Asignment Operator.
