Never mind, I answered my own question. That id value is used internally for tying the html components to their values. We're supposed to use the void* userparameter.
Each instance of control has a unique id. Each control pointer is unique. You can keep a table of control pointers and search through it or you can keep a map of ID to some structure you have to track them.
Best is to use a lambda for each control type
I'm trying to work out how to modify the sender id as presented to the callback function. In the examples given, like the below, the method specifies a callback "textCall"...
ESPUI.text("Text Test:", &textCall, ControlColor::Alizarin, "a Text Field");
And in the examples, that callback contains a "Control" parameter with an id available as
sender->id
.In my tests with multiple fields, it appears this value is dynamically generated, as each field contains a different id. My question is, are we able to set this in advance? I'd like to use a single callback for multiple fields, however I'd need a way to determine which field is calling the callback.
