4 * @brief General Elementary API. Functions that don't relate to
5 * Elementary objects specifically.
7 * Here are documented functions which init/shutdown the library,
8 * that apply to generic Elementary objects, that deal with
9 * configuration, et cetera.
11 * @ref general_functions_example_page "This" example contemplates
12 * some of these functions.
21 * Defines couple of standard Evas_Object layers to be used
22 * with evas_object_layer_set().
24 * @note whenever extending with new values, try to keep some padding
25 * to siblings so there is room for further extensions.

125 * Initialize Elementary
127 * @param[in] argc System's argument count value
128 * @param[in] argv System's pointer to array of argument strings
129 * @return The init counter value.
131 * This function initializes Elementary and increments a counter of
132 * the number of calls to it. It returns the new counter's value.
134 * @warning This call is exported only for use by the @c ELM_MAIN()
135 * macro. There is no need to use this if you use this macro (which
136 * is highly advisable). An elm_main() should contain the entry
137 * point code for your application, having the same prototype as
138 * elm_init(), and @b not being static (putting the @c EAPI_MAIN symbol
139 * in front of its type declaration is advisable). The @c
140 * ELM_MAIN() call should be placed just after it.
143 * @dontinclude bg_example_01.c
147 * See the full @ref bg_example_01_c "example".
149 * @see elm_shutdown().
152 EAPI int elm_init(int argc, char **argv);
155 * Shut down Elementary
157 * @return The init counter value.
159 * This should be called at the end of your application, just
160 * before it ceases to do any more processing. This will clean up
161 * any permanent resources your application may have allocated via
162 * Elementary that would otherwise persist.
164 * @see elm_init() for an example
168 EAPI int elm_shutdown(void);
171 * Run Elementary's main loop
173 * This call should be issued just after all initialization is
174 * completed. This function will not return until elm_exit() is
175 * called. It will keep looping, running the main
176 * (event/processing) loop for Elementary.
178 * @see elm_init() for an example
182 EAPI void elm_run(void);
185 * Exit Elementary's main loop
187 * If this call is issued, it will flag the main loop to cease
188 * processing and return back to its parent function (usually your
189 * elm_main() function).
191 * @see elm_init() for an example. There, just after a request to
192 * close the window comes, the main loop will be left.
194 * @note By using the appropriate #ELM_POLICY_QUIT on your Elementary
195 * applications, you'll be able to get this function called automatically for you.

267 * @return @c EINA_TRUE on success or @c EINA_FALSE, on error.
269 * Elementary policies define applications' behavior,
270 * somehow. These behaviors are divided in policy groups (see
271 * #Elm_Policy enumeration). This call will emit the Ecore event
272 * #ELM_EVENT_POLICY_CHANGED, which can be hooked at with
273 * handlers. An #Elm_Event_Policy_Changed struct will be passed,
276 * @note Currently, we have only one policy identifier/group
277 * (#ELM_POLICY_QUIT), which has two possible values.

288 * identifier. Will be @c 0 if @p policy passed is invalid.

295 * Change the language of the current application
297 * The @p lang passed must be the full name of the locale to use, for
298 * example "en_US.utf8" or "es_ES@euro".
300 * Changing language with this function will make Elementary run through
301 * all its widgets, translating strings set with
302 * elm_object_domain_translatable_text_part_set(). This way, an entire
303 * UI can have its language changed without having to restart the program.
305 * For more complex cases, like having formatted strings that need
306 * translation, widgets will also emit a "language,changed" signal that
307 * the user can listen to to manually translate the text.
309 * @param lang Language to set, must be the full name of the locale
313 EAPI void elm_language_set(const char *lang);
316 * Set the text for an objects' part, marking it as translatable.
318 * The string to set as @p text must be the original one. Do not pass the
319 * return of @c gettext() here. Elementary will translate the string
320 * internally and set it on the object using elm_object_part_text_set(),
321 * also storing the original string so that it can be automatically
322 * translated when the language is changed with elm_language_set().
324 * The @p domain will be stored along to find the translation in the
325 * correct catalog. It can be NULL, in which case it will use whatever
326 * domain was set by the application with @c textdomain(). This is useful
327 * in case you are building a library on top of Elementary that will have
328 * its own translatable strings, that should not be mixed with those of
329 * programs using the library.
331 * @param obj The object containing the text part
332 * @param part The name of the part to set
333 * @param domain The translation domain to use
334 * @param text The original, non-translated text to set

342 #define elm_object_translatable_text_set(obj, text) elm_object_domain_translatable_text_part_set((obj), NULL, NULL, (text))
345 * Gets the original string set as translatable for an object
347 * When setting translated strings, the function elm_object_part_text_get()
348 * will return the translation returned by @c gettext(). To get the
349 * original string use this function.
351 * @param obj The object
352 * @param part The name of the part that was set
354 * @return The original, untranslated string
