From 843985e953ddcc3d57a62641b377c8d3222859e2 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 22 Jan 2013 18:09:36 +0900 Subject: [PATCH] perf gtk/browser: Convert hpp helpers to a function The hpp helpers do same job for each field so it was implemented as macro in order to access those fields easily. But it gets cumbersome to maintain a large function in a macro as the function grows. Factor it out to a function with a little helper macro to access field.
