Re: Porting a GTK 1.x application to current version

[Carlos Pereira <jose carlos pereira ist utl pt>]

Hi Fabian,

1) In the beginning, you may wish to use:

#define GTK_ENABLE_BROKEN

to allow GTK 1* widgets to run with GTK 2* libs. This makes the 
transition much easier, because you can port all your GTK 1* widgets 
little by little, until one fine day you will be able to get rid of 
#define GTK_ENABLE_BROKEN...

2) When you reach that stage, you might wish to add the following lines 
to your makefiles:

override CFLAGS += -DG_DISABLE_DEPRECATED -DGDK_DISABLE_DEPRECATED \
        -DGDK_PIXBUF_DISABLE_DEPRECATED -DGTK_DISABLE_DEPRECATED \
#       -DGSEAL_ENABLE \
#       -DG_DISABLE_SINGLE_INCLUDES -DATK_DISABLE_SINGLE_INCLUDES \
#       -DGDK_PIXBUF_DISABLE_SINGLE_INCLUDES -DGTK_DISABLE_SINGLE_INCLUDES

When your app compiles with the uncommented lines, you have essentially 
a GTK 2* app. When you manage to compile your app with the DGSEAL and 
INCLUDES directives, then you have essentially a GTK 3* app.

Cheers,
Carlos
