FXint FX::FXGradientBar::getSegment (  FXint  x,
FXint  y
)  const
 

Obtain segment containing location x, y.

Returns -1 if no matching segment was found.

FXint FX::FXGradientBar::getGrip (  FXint  sg,
FXint  x,
FXint  y
)  const
 

Get the grip in segment sg which is closest to location (x, y), one of GRIP_LOWER, GRIP_SEG_LOWER, GRIP_MIDDLE, GRIP_SEG_UPPER, GRIP_UPPER or GRIP_NONE.

The gradient bar makes a copy of the input segments array.

void FX::FXGradientBar::getGradients (  FXGradient *&  segments,
FXint &  nsegments
)  const
 

Return a copy of the gradient segments.

The array of segments is allocated using FXMALLOC and should be freed by the caller using FXFREE.
