Description

The PanelApplet object is an object which encapsulates an applet. It is a GtkContainer which may contain a single widget. This widget, in turn, should contain all widgets exposed by the applet.

A PanelApplet is associated with a BonoboControl. The control makes the cross process UI emmbedding required by applets possible.

void        user_function                  (PanelApplet *panelapplet,
                                            PanelAppletBackgroundType arg1,
                                            gpointer arg2,
                                            GdkPixmap *arg3,
                                            gpointer user_data);

Emitted when the background of the panel changes. Use type to determine which, if any, of color and pimxap is valid.

panelapplet :

The object which received the signal.

arg1 :

arg2 :

arg3 :

user_data :

user data set when the signal handler was connected.


The "change-orient" signal

void        user_function                  (PanelApplet *panelapplet,
                                            gint arg1,
                                            gpointer user_data);

Emitted when the orientation of the panel changes.

panelapplet :

The object which received the signal.

arg1 :

user_data :

user data set when the signal handler was connected.


The "change-size" signal

void        user_function                  (PanelApplet *panelapplet,
                                            gint arg1,
                                            gpointer user_data);

Emitted when the size of the panel changes.

Note: this is different for size negotiation which is handled by size_request() and size_allocate() as usual. This signal should be used to determine what font size or widget layout to use depending on the size of the panel.

panelapplet :

The object which received the signal.

arg1 :

user_data :

user data set when the signal handler was connected.


The "move-focus-out-of-applet" signal

void        user_function                  (PanelApplet *panelapplet,
                                            GtkDirectionType arg1,
                                            gpointer user_data);

panelapplet :

the object which received the signal.

arg1 :

user_data :

user data set when the signal handler was connected.
