Description

Graph modules implement operations on graphs, e.g., curve fitting.

Functions

GwyGraphFunc ()

void
(*GwyGraphFunc) (GwyGraph *graph,
                 const gchar *name);

The type of graph function.

Parameters

graph

Graph (a GwyGraph) to operate on.

 

name

Function name from as registered with gwy_graph_func_register() (single-function modules can safely ignore this argument).

 

gwy_graph_func_register ()

gboolean
gwy_graph_func_register (const gchar *name,
                         GwyGraphFunc func,
                         const gchar *menu_path,
                         const gchar *stock_id,
                         guint sens_mask,
                         const gchar *tooltip);

Registers a graph function.

Note: the string arguments are not copied as modules are not expected to vanish. If they are constructed (non-constant) strings, do not free them. Should modules ever become unloadable they will get chance to clean-up.

Parameters

name

Name of function to register. It should be a valid identifier and if a module registers only one function, module and function names should be the same.

 

func

The function itself.

 

menu_path

Menu path under Graph menu. The menu path should be marked translatabe, but passed untranslated (to allow merging of translated and untranslated submenus).

 

stock_id

Stock icon id for toolbar.

 

sens_mask

Sensitivity mask (a combination of GwyMenuSensFlags flags). Usually it is equal to GWY_MENU_FLAG_GRAPH, but it's possible to set other requirements.

 

tooltip

Tooltip for this function.

 

Returns

Normally TRUE; FALSE on failure.

gwy_graph_func_run ()

void
gwy_graph_func_run (const gchar *name,
                    GwyGraph *graph);

Runs a graph function identified by name .

Parameters

name

Graph function name.

 

graph

Graph (a GwyGraph).

 

gwy_graph_func_exists ()

gboolean
gwy_graph_func_exists (const gchar *name);

Checks whether a graph function exists.

Parameters

name

Graph function name.

 

Returns

TRUE if function name exists, FALSE otherwise.

gwy_graph_func_get_menu_path ()

const gchar *
gwy_graph_func_get_menu_path (const gchar *name);

Gets menu path of a graph function.

The returned menu path is only the tail part registered by the function, i.e., without any leading "/Graph".

Parameters

name

Graph function name.

 

Returns

The menu path. The returned string is owned by the module.

gwy_graph_func_get_stock_id ()

const gchar *
gwy_graph_func_get_stock_id (const gchar *name);

Gets stock icon id of a graph function.

Parameters

name

Graph function name.

 

Returns

The stock icon id. The returned string is owned by the module.

gwy_graph_func_get_tooltip ()

const gchar *
gwy_graph_func_get_tooltip (const gchar *name);

Gets tooltip for a graph function.

Parameters

name

Graph function name.

 

Returns

The tooltip. The returned string is owned by the module.

gwy_graph_func_get_sensitivity_mask ()

guint
gwy_graph_func_get_sensitivity_mask (const gchar *name);

Gets menu sensititivy mask for a graph function.

Parameters

name

Graph function name.

 

Returns

The menu item sensitivity mask (a combination of GwyMenuSensFlags flags).

gwy_graph_func_foreach ()

void
gwy_graph_func_foreach (GFunc function,
                        gpointer user_data);

Calls a function for each graph function.

Parameters

function

Function to run for each graph function. It will get function name (constant string owned by module system) as its first argument, user_data as the second argument.

 

user_data

Data to pass to function .

 

gwy_graph_func_current ()

const gchar *
gwy_graph_func_current (void);

Obtains the name of currently running graph function.

If no graph function is currently running, NULL is returned.

If multiple nested functions are running (which is not usual but technically possible), the innermost function name is returned.

Returns

The name of currently running graph function or NULL.

Since: 2.38
