Description

All application and module settings are stored in a one big GwyContainer which can be obtained by gwy_app_settings_get(). Then you can use GwyContainer functions to get and save settings.

The rest of the setting manipulating functions is normally useful only in main application.

Details

gwy_app_settings_get ()

GwyContainer* gwy_app_settings_get          (void);

Gets the Gwyddion settings.

The settings are a GwyContainer automatically loaded at program startup and saved ad its exit. For storing persistent module data you should use "/module/YOUR_MODULE_NAME/" prefix.

Returns :

The settings as a GwyContainer.

gwy_app_settings_free ()

void        gwy_app_settings_free           (void);

Frees Gwyddion settings.

Should not be called only by main application.

gwy_app_settings_save ()

gboolean    gwy_app_settings_save           (const gchar *filename);

Saves the settings.

Use gwy_app_settings_get_settings_filename() to obtain a suitable default filename.

`filename` :	A filename to save the settings to.
Returns :	Whether it succeeded.

gwy_app_settings_load ()

gboolean    gwy_app_settings_load           (const gchar *filename);

`filename` :
Returns :

gwy_app_settings_create_config_dir ()

gboolean    gwy_app_settings_create_config_dir
                                            (void);

Create gwyddion config directory.

Returns : Whether it succeeded (also returns TRUE if the directory already exists).

gwy_app_settings_get_module_dirs ()

gchar**     gwy_app_settings_get_module_dirs
                                            (void);

Returns a list of directories to search modules in.

Returns : The list of module directories as a newly allocated array of newly allocated strings, to be freed with g_str_freev() when not longer needed.

gwy_app_settings_get_settings_filename ()

gchar*      gwy_app_settings_get_settings_filename
                                            (void);

Returns a suitable human-readable settings file name.

Returns :

The file name as a newly allocated string.

gwy_app_settings_get_log_filename ()

gchar*      gwy_app_settings_get_log_filename
                                            (void);

Returns a suitable log file name.

Returns :

The file name as a newly allocated string.

gwy_app_settings_get_recent_file_list_filename ()

gchar*      gwy_app_settings_get_recent_file_list_filename
                                            (void);

Returns a suitable recent file list file name.

Returns :

The file name as a newly allocated string.

gwy_app_gl_init ()

gboolean    gwy_app_gl_init                 (int *argc,
                                             char ***argv);

Checks for working OpenGL and initializes it.

When OpenGL support is not compiled in, this function does not do anything. When OpenGL is supported, it calls gtk_gl_init_check() and gwy_widgets_gl_init() (if the former succeeeds).

`argc` :	Address of the argc parameter of `main()`. Passed to `gtk_gl_init_check()`.
`argv` :	Address of the argv parameter of `main()`. Passed to `gtk_gl_init_check()`.
Returns :	`TRUE` if OpenGL initialization succeeeded.

gwy_app_gl_is_ok ()

gboolean    gwy_app_gl_is_ok                (void);

Returns OpenGL availability.

Returns : The return value is the same as return value of gwy_app_gl_init(), which must be called prior to this function.
