From 9623350767d51e3d7dd7b18e97bb0b9b2555f708 Mon Sep 17 00:00:00 2001 From: rkrolib Date: Mon, 10 Nov 2003 10:00:21 +0000 Subject: [PATCH] Hm.

Should be pretty close to in-line with the style of changes that I've been making else- where. git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@331 7f0cb862-5218-0410-a997-914c9d46530a --- freeglut/freeglut/src/freeglut_structure.c | 263 +++++++++++---------- 1 file changed, 133 insertions(+), 130 deletions(-) diff --git a/freeglut/freeglut/src/freeglut_structure.c b/freeglut/freeglut/src/freeglut_structure.c index cc1e9a3..21b6cfb 100644 --- a/freeglut/freeglut/src/freeglut_structure.c +++ b/freeglut/freeglut/src/freeglut_structure.c @@ -120,8 +120,8 @@ SFG_Window* fgCreateWindow( SFG_Window* parent, const char* title, */ SFG_Menu* fgCreateMenu( FGCBMenu menuCallback ) { - int x = 100, y = 100, w = 100, h = 100 ; - SFG_Window *current_window = fgStructure.Window ; + int x = 100, y = 100, w = 100, h = 100; + SFG_Window *current_window = fgStructure.Window; /* * Have the menu object created @@ -136,34 +136,34 @@ SFG_Menu* fgCreateMenu( FGCBMenu menuCallback ) if( !fgState.Time.Set ) glutInit( &fakeArgc, NULL ); - menu->ParentWindow = fgStructure.Window ; + menu->ParentWindow = fgStructure.Window; /* * Create a window for the menu to reside in.
