Genlist - different width options

This example doesn't present any other feature that is not already present in the other examples, but visually shows the difference between using the default list options (first list of the example), setting the horizontal mode to ELM_LIST_LIMIT (second list), enabling compress mode (third list) and using height_for_width option (fourth list).

The full code for this example is listed below:

//Compile with:
//gcc -g genlist_example_03.c -o genlist_example_03 `pkg-config --cflags --libs elementary`
#include <Elementary.h>
#define N_ITEMS 30

{
time_t t = (time_t)ecore_time_unix_get();
char buf[256];
int i = (int)(long)data;
if (!strcmp(part, "elm.text"))
snprintf(buf, sizeof(buf), "Item # %i", i);
else
{
int n;
snprintf(buf, sizeof(buf), "created at %s", ctime(&t));
n = strlen(buf);
buf[n - 1] = '\0';
}
return strdup(buf);
}
