Detailed Description

Interactive specification of a 3D point.

PickPoint expects WindowEvent, but it checks safely.

The fourth element is non-zero when the point is valid.

Member Function Documentation

◆ drawFeedback()

void fe::ext::PickPoint::drawFeedback ( sp< DrawI > spDrawI ) const

virtual

Render the point in some fashion.

Implements fe::ext::PointI.

◆ point()

SpatialVector & fe::ext::PickPoint::point ( const WindowEvent::Mask & mask )

virtual

Get the point matching a window mask.

The implementation may distinguish different points based on the mask with its own criteria. The only restriction is that every mask is associated for some point.

An example would be six available points: three mouse buttons, each with a press and release point.

Implements fe::ext::PointI.
