/**
|
||||||
|
* @page tutorial_edje_swallow2 Swallow example 2
|
||||||
|
*
|
||||||
|
* This example will show you how to load an image using evas and fill a swallow with it.
|
||||||
|
* It's basically almost like the last example, but with a minor change.
|
||||||
|
*
|
||||||
|
* This variables are used to store the name of the image that is going to be used,
|
||||||
|
* the path to it and a variable that will store the error cause if something goes wrong.
|
||||||
|
*
|
||||||
|
* Here it is:
|
||||||
|
* @dontinclude edje-swallow2.c
|
||||||
|
* @skipline char edje_file
|
||||||
|
* @skipline const char *img
|
||||||
|
* @skipline Evas_Load
|
||||||
|
*
|
||||||
|
*
|
||||||
|
* Then we load the image with this command:
|
||||||
|
*
|
||||||
|
* @skip img =
|
||||||
|
* @until evas_object_image_file_set(img,
|
||||||
|
*
|
||||||
|
* To check if we had some problem we use:
|
||||||
|
*
|
||||||
|
* @skip err = evas
|
||||||
|
* @until }
|
||||||
|
*
|
||||||
|
* Now we are going to swallow it and check if worked. If you notice we are
|
||||||
|
* using "part_one" as argument. We do this because we must explicit what part of our
|
||||||
|
* .edc file we want to swallow:
|
||||||
|
*
|
||||||
|
* @skip edje_object_part
|
||||||
|
* @until printf
|
||||||
|
*
|
||||||
|
* The example's window should look like this picture:
|
||||||
|
*
|
||||||
|
* @image html swallow2final.png
|
||||||
|
* @image rtf swallow2final.png
|
||||||
|
* @image latex swallow2final.eps width=\textwidth
|
||||||
|
*
|
||||||
|
* The complete .edc file:
|
||||||
|
* @include swallow.edc
|
||||||
|
*
|
||||||
|
* And the source code:
|
||||||
|
* @include edje-swallow2.c
|
||||||
|
*
|
||||||
|
* To compile use this command:
|
||||||
|
* @verbatim
|
||||||
|
* gcc -o edje-swallow2 edje-swallow2.c -DPACKAGE_BIN_DIR=\"/Where/enlightenment/is/installed/bin\"
|
||||||
|
* -DPACKAGE_LIB_DIR=\"/Where/enlightenment/is/installed/lib\"
|
||||||
|
* -DPACKAGE_DATA_DIR=\"/Where/enlightenment/is/installed/share\"
|
||||||
|
* `pkg-config --cflags --libs evas ecore ecore-evas edje`
|
||||||
|
*
|
||||||
|
* edje_cc swallow.edc
|
||||||
