gint gnc_plugin_add_actions	(	GtkUIManager *	ui_merge,
		GtkActionGroup *	action_group,
		const gchar *	filename
	)

Load a new set of actions into an existing UI.

See gnc-plugin.h for documentation on the function arguments.

Load a new set of actions into an existing UI. The actions from the provided group will be merged into the pre-existing ui, as directed by the specified file.

Parameters:

ui_merge	A pointer to the UI manager data structure for a window.
action_group	The set of actions provided by a given plugin.
filename	The name of the ui description file. This file name will be searched for in the ui directory.

Returns:: The merge_id number for the newly merged UI. If an error occurred, the return value is 0.

void gnc_plugin_init_short_names	(	GtkActionGroup *	action_group,

	)

Add "short" labels to existing actions. The "short" label is the string used on toolbar buttons when the action is visible.

See gnc-plugin.h for documentation on the function arguments.

Add "short" labels to existing actions. The "short" label is the string used on toolbar buttons when the action is visible. All toolbar buttons are homogeneous in size and are sized to fit the longest label. Therefore, this structure should be used if an action name is more than one word. This way the menu can have the label "Whizzy Feature", while the toolbar button only has the label "Whizzy".

Parameters:

action_group	The group of all actions associated with a plugin or plugin page. All actions to me modified must be in this group.
toolbar_labels	A pointer to a NULL terminated array of data action_toolbar_labels items.

void gnc_plugin_remove_from_window	(	GncPlugin *	plugin,

Remove the specified plugin from the specified window. This function will call the plugin to perform any plugin specific actions, remove any gconf notifications that were set up for the page, and remove the page's user interface from the window.

Parameters:

plugin	The plugin to be removed.
window	The window the plugin should be removed from.
type	An identifier for the type of window specified.

void gnc_plugin_update_actions	(	GtkActionGroup *	action_group,

	)

Update a property on a set of existing GtkActions. This function can be easily used to make a list of actions visible, invisible, sensitive, or insensitive.

Parameters:

action_group	The group of all actions associated with a plugin or plugin page. All actions to be modified must be contained in this group.
action_names	A NULL terminated list of actions names that should modified.
property_name	The property name to be changed on the specified actions. The only two GtkAction properties that it makes sense to modify are "visible" and "sensitive".
value	A boolean specifying the new state for the specified property.
