`uiControl` is an opaque type that describes a control.
`uiControlType()` is the type identifier of a `uiControl` as passed to `uiCheckControlType()`. You rarely need to call this directly; the `uiControl()` conversion macro does this for you.
`uiControlType()` is the type identifier of a `uiControl` as passed to `uiCheckControlType()`. You rarely need to call this directly; the `uiControl()` conversion macro does this for you. A control type identifier of 0 is always invalid; this can be used to initialize the variables that hold the returned identifiers from `uiRegisterControlType()`.
