From dd7595a3475407a7fa96a97393bae8c5220e8762 Mon Sep 17 00:00:00 2001 From: David Walter Seikel Date: Wed, 4 Jan 2012 18:41:13 +1000 Subject: Add the base Enlightenment Foundation Libraries - eina, eet, evas, ecore, embryo, and edje. Note that embryo wont be used, but I'm not sure yet if you can build edje without it. --- libraries/edje/src/examples/edje-table.c | 165 +++++++++++++++++++++++++++++++ 1 file changed, 165 insertions(+) create mode 100644 libraries/edje/src/examples/edje-table.c (limited to 'libraries/edje/src/examples/edje-table.c') diff --git a/libraries/edje/src/examples/edje-table.c b/libraries/edje/src/examples/edje-table.c new file mode 100644 index 0000000..3866d22 --- /dev/null +++ b/libraries/edje/src/examples/edje-table.c @@ -0,0 +1,165 @@ +/** + * Simple Edje example illustrating table functions. + * + * You'll need at least one Evas engine built for it (excluding the + * buffer one).
