Description

The functions in this page are mostly only for the information of developers -- they should never needt o call them directly. Typically, a druid will connect to the various signals described here as a way of controlling the behaviour of druids that do not just proceed in a front-to-back fashion (for example, where the subsequent pages depend upon the choice made at some point).

Details

GnomeDruidPage

typedef struct _GnomeDruidPage GnomeDruidPage;

The widget for a aprticular page in a druid.


gnome_druid_page_new ()

GtkWidget*  gnome_druid_page_new            (void);

Creates a new GnomeDruidPage.

Returns : The newly created GnomeDruidPage.

gnome_druid_page_next ()

gboolean    gnome_druid_page_next           (GnomeDruidPage *druid_page);

This will emit the "next" signal for that particular page. It is called by gnome-druid exclusively. It is expected that non-linear Druid's will override this signal and return TRUE if it handles changing pages.

druid_page : A DruidPage widget.
Returns : This function will return FALSE by default.

gnome_druid_page_prepare ()

void        gnome_druid_page_prepare        (GnomeDruidPage *druid_page);

This emits the "prepare" signal for the page. It is called by gnome-druid exclusively. This function is called immediately prior to a druid page being shown so that it can "prepare" for display.

druid_page : A DruidPage widget.

gnome_druid_page_back ()

gboolean    gnome_druid_page_back           (GnomeDruidPage *druid_page);

This will emit the "back" signal for that particular page. It is called by gnome-druid exclusively. It is expected that non-linear Druid's will override this signal and return TRUE if it handles changing pages.

druid_page : A DruidPage widget.
Returns : This function will return FALSE by default.

gnome_druid_page_cancel ()

gboolean    gnome_druid_page_cancel         (GnomeDruidPage *druid_page);

This will emit the "cancel" signal for that particular page. It is called by gnome-druid exclusively. It is expected that a Druid will override this signal and return TRUE if it does not want to exit.

druid_page : A DruidPage widget.
Returns : This function will return FALSE by default.

gnome_druid_page_finish ()

void        gnome_druid_page_finish         (GnomeDruidPage *druid_page);

This emits the "finish" signal for the page. It is called by gnome-druid exclusively.

druid_page : A DruidPage widget.

Signal Details

The "back" signal

gboolean    user_function                  (GnomeDruidPage *druidpage,
                                            GtkWidget      *widget,
                                            gpointer        user_data)      : Run last

druidpage : the object which received the signal.
widget : The GnomeDruid containg this page.
user_data : user data set when the signal handler was connected.
Returns : TRUE if the signal handler has changed the page (since this stops all further emission of the signal), FALSE otherwise.

The "cancel" signal

gboolean    user_function                  (GnomeDruidPage *druidpage,
                                            GtkWidget      *widget,
                                            gpointer        user_data)      : Run last

druidpage : the object which received the signal.
widget : The GnomeDruid containg this page.
user_data : user data set when the signal handler was connected.
Returns : TRUE if the druid does not want to exit yet, FALSE if the exit should continue.

The "finish" signal

void        user_function                  (GnomeDruidPage *druidpage,
                                            GtkWidget      *widget,
                                            gpointer        user_data)      : Run last

druidpage : the object which received the signal.
widget : The GnomeDruid containg this page.
user_data : user data set when the signal handler was connected.

The "next" signal

gboolean    user_function                  (GnomeDruidPage *druidpage,
                                            GtkWidget      *widget,
                                            gpointer        user_data)      : Run last

druidpage : the object which received the signal.
widget : The GnomeDruid containg this page.
user_data : user data set when the signal handler was connected.
Returns : TRUE if the signal handler has changed the page (since this stops all further emission of the signal), FALSE otherwise.

                                            GtkWidget      *widget,
