10 // At the time of writing this, there were two common ways of binding our C++
11 // code to the gobject C system. We either defined a whole bunch of "static
12 // MethodThunk()" which just called nonstatic Method()s on a class (which hurt
13 // readability of the headers and signal connection code) OR we declared
14 // "static Method()" and passed in the current object as the gpointer (and hurt
15 // readability in the implementation by having "context->" before every
16 // variable).
17
18 // The hopeful result of using these macros is that the code will be more
19 // readable and regular. There shouldn't be a bunch of static Thunks visible in
20 // the headers and the implementations shouldn't be filled with "context->"
21 // de-references.
