Re: [gtkmm] pb when checking notebook pages ...

[cedric <cedric probesys com>]

Hi!


thanks for your new response, but the booleans are not sufficient and i 
d like to avoid using a list... the ideal would be a way to access the 
text of the notebook's tab label!

here is my NoteBookLabel class



----------------------------------------------------


class NoteBookLabel : public Gtk::HBox

{

Gtk::Label label; //contains the text of the tab label

Gtk::Button b; //the button to click on for closing the notebook page

Gtk::Image *image; //the little cross which is in the above button


Formularies *form_ptr; //the widget that is the "body" of the notebook page

//Formularies is one of my classes and is a Gtk::VBox


void NoteBookLabel::on_close_clicked( ); //close the notebook page when 
one clicks one the button b


}


----------------------------------------------------


when i append a page into my notebook, i do:


notebook.append(a_formulary, a_notebooklabel);


----------------------------------------------------


so my goal is to access to "label". i used get_tab_label and others 
things by i never successed :-[

if there are no way to do it i ll resign to use a list of open pages :'( 
or i let it like that :x



best regards,

cedric
