gtypeString :: GType Source #

Note: compile-time vs run-time GTypes

Notice that there are two types of GType's: the fundamental ones, which are created with G_TYPE_MAKE_FUNDAMENTAL(n) and always have the same runtime representation, and the ones that are registered in the GObject type system at runtime, and whose CGType may change for each program run (and generally does).

For the first type it is safe to use hsc to read the numerical values of the CGType at compile type, but for the second type it is essential to call the corresponding _get_type() function at runtime, and not use the value of the corresponding "constant" at compile time via hsc.

GType of strings.
