It's a little hacky, but try this:
Group {
name pixelMeasure
help "This node displays the distance in pixels between two points\n\n-
John Mangia"
label "x distance: \[value this.calc.x]\ny distance: \[value this.calc.y]"
selected true
xpos -589
ypos -334
addUserKnob {20 pixelMeasure}
addUserKnob {6 lockY l "lock y" +STARTLINE}
addUserKnob {12 pointA}
pointA {764 796}
addUserKnob {12 pointB}
pointB {1460 {"this.lockY == True ? this.pointA.y :this.pointB.y" x1001
820 x1023 502 x1035 1}}
addUserKnob {12 calc l INVISIBLE +INVISIBLE}
calc {{"abs(this.pointA.x - this.pointB.x)"} {"abs(this.pointA.y -
this.pointB.y)"}}
}
Input {
inputs 0
name Input1
selected true
xpos -339
ypos -110
}
Output {
name Output1
xpos -339
ypos 61
}
end_group
