Member Function Documentation

virtual void Elve::EdgeLook::addToPath

(

QPainterPath &

path

)

[pure virtual]

add the shape of this edge

Parameters:

path	path to be updated

The edges in elve are batched together to speed up drawing, this is thus the only way to add geometry from the edge, update the provided path by adding the current edge to it. Don't clear the given path.

const NodeLook & Elve::EdgeLook::from

(

)

const

get the node from which the edge is coming

Returns:

Definition at line 16 of file EdgeLook.cpp.

Index Elve::EdgeLook::iFrom

(

)

const

get the output index (pin) from which the edge is coming

Returns:

Definition at line 8 of file EdgeLook.cpp.

Index Elve::EdgeLook::iTo

(

)

const

get the input index (pin) to which the edge is going

Returns:

Definition at line 12 of file EdgeLook.cpp.

virtual QPen Elve::EdgeLook::pen

(

)

const [pure virtual]

state the pen that must draw this edge

Returns:

the pen

Since edges are batched in elve, and qt can draw only with one pen at once. Edges are sorted by Pen values to group drawing of edges sharing common pens.

const NodeLook & Elve::EdgeLook::to

(

)

const

get the node to which the edge is going

Returns:
