Dynamic Linkage of LocatorPane and InputField
$begingroup$
How do I get the InputField to coordinate with the LocatorPane so that a change in each control changes the other to be in agreement? It would be nice if the function was self-contained and was dynamically linked to a second similar control where the variable is radians. The angle control is based on this (see Applications). Related links do not address or solve this particular issue; links such as this this, and this
fDeg[Dynamic[angleDeg_]] :=
DynamicModule[{p, angleRad, angleCalc, dtr = Degree},
angleCalc[newp_,
oldp_] := (angleRad =
angleRad + ArcCos[newp.oldp] Sign[Cross[newp].(newp - oldp)];
If[0 < angleRad, angleRad = Mod[angleRad, +2*Pi]];
If[0 > angleRad, angleRad = Mod[angleRad, -2*Pi]];
angleDeg = angleRad/dtr;
f[angleDeg];
p = {Cos[angleRad], Sin[angleRad]});
angleRad = angleDeg*dtr;
p = {Cos[angleRad], Sin[angleRad]};
LocatorPane[Dynamic[p, (angleCalc @@ Normalize /@ {#, p}) &],
Dynamic@Show[
Graphics[{Circle, Arrowheads[0.15],
Arrow[Dynamic[{{0, 0}, p}]]}, ImageSize -> Tiny],
Graphics[{Dynamic[{Text[
NumberForm[angleDeg, {3, 2}], {0, 0}]}]}]],
Appearance -> None]];
aDeg = 45;
Column[{
"Degrees:",
fDeg[Dynamic[aDeg]],
"aDeg: ",
InputField[Dynamic[aDeg],
FieldSize -> 6]
}, Alignment -> Center]

Consider the following refactoring of your code
First, the locator pane is used to set a point location constrained on a circle with unit radius (this part borrowed heavily from an example in the documentation for LocatorPane). A degree value is then calculated from the coordinates of tha tpoint.
Secondly, the input field is used to read in a degree value, which is then used to update the position of the dynamic point pt using the second argument of Dynamic.
DynamicModule[
{pt = {0, 1.}},
Column[{
"Degrees:", Dynamic[(ArcTan @@ pt)/Degree],
LocatorPane[
Dynamic[pt],
Graphics[{
Circle,
PointSize[Large],
Dynamic[Arrow[{{0, 0}, pt/Norm[pt]}]]
}],
Appearance -> None
],
InputField[
Dynamic[(ArcTan @@ pt)/Degree, (pt = N@{Cos[#1 Degree], Sin[#1 Degree]}) &],
FieldSize -> Tiny
]
}, Alignment -> Center
]
]
This keeps both fields in sync with each other:
