I'm trying to produce a container control that will allow entry of an angle (or a time interval) in either DMS (HMS) or decimal degrees (hours).
The image below shows the control in question. It contains 3 container controls (one for each of D, M, and S) each with a slider and a text field so changing either the slider or the text field will update the other. The outer container also has a text field (on the right) that is to display the angle in decimal degrees.
My question is, how do I get changes in each of the internal (slider/textfield) containers to immediately change the value in the outer decimal degrees field?
