G_DEFINE_TYPE_WITH_CODE()

G_DEFINE_TYPE_WITH_CODE	(	GncPlugin	,
		gnc_plugin	,
		G_TYPE_OBJECT	,
		G_ADD_PRIVATE(GncPlugin)
	)

Initialize the class for the new gnucash plugin object.

This will set up any function pointers that override functions in the parent class, and also installs the proprieties that are unique to this class.

Parameters

klass

The new class structure created by the object system.

Definition at line 61 of file gnc-plugin.c.

{
    GObjectClass *gobject_class = G_OBJECT_CLASS (klass);

    gobject_class->constructed = gnc_plugin_constructed;

This function adds the tooltip callbacks to make the tooltips appear in the status bar.

Parameters

menubar	The main window menu bar widget.
menubar_model	The GMenuModel used to create the menubar.
statusbar	The status bar widget in the main window.

gnc_plugin_add_toolbar_tooltip_callbacks()

void gnc_plugin_add_toolbar_tooltip_callbacks	(	GtkWidget *	toolbar,
		GtkWidget *	statusbar
	)

This function adds the tooltip callbacks to make the tooltips appear in the status bar.

Parameters

toolbar	The main window tool bar widget.
statusbar	The status bar widget in the main window.

gnc_plugin_get_name()

const gchar * gnc_plugin_get_name

(

GncPlugin *

plugin

)

Retrieve the textual name of a plugin.

Parameters

plugin

The plugin whose name should be returned.

Returns

A string containing the name of this plugin

Definition at line 212 of file gnc-plugin.c.

    return (GNC_PLUGIN_GET_CLASS(plugin)->plugin_name);
}

gnc_plugin_init_short_names()

void gnc_plugin_init_short_names	(	GtkWidget *	toolbar,
		GncToolBarShortNames *	toolbar_labels
	)

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.

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 GncToolBarShortNames items.

Definition at line 229 of file gnc-plugin.c.

    {
        GtkWidget *tool_item = gnc_find_toolbar_item (toolbar, toolbar_labels[i].action_name);

        if (!tool_item)
            continue;

        gtk_tool_button_set_label (GTK_TOOL_BUTTON(tool_item), _(toolbar_labels[i].short_label));
        gtk_tool_button_set_use_underline (GTK_TOOL_BUTTON(tool_item), TRUE);
    }
}

gnc_plugin_remove_from_window()

void gnc_plugin_remove_from_window	(	GncPlugin *	plugin,
		GncMainWindow *	window,

	)

Remove the specified plugin from the specified window.

This function will call the plugin to perform any plugin specific actions 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_set_actions_enabled	(	GActionMap *	action_map,
		const gchar **	action_names,
		gboolean	enable
	)

This function sets the sensitivity of a GAction in a specific group.

Parameters

action_map	The action map associated with the window.
