Re: How to bind a GTKWindow in C++ code to the .UI file

[Luca Bacci <luca bacci982 gmail com>]

Try with:

builder->get_widget("main_win", main_win);

if (main_win == nullptr) {

  /* handle error */

}

Gtk::Builder::get_widget() method reference:

https://developer.gnome.org/gtkmm/stable/classGtk_1_1Builder.html#ae525dfa187377dcdc1179a52df3d160a

Have a look here for a detailed guide:

Hi

 

I have a .UI file where a window with some custom widgets is declared.

Now the main window is named "main_win"

 

This is how the UI file is initialized in the main function of the application- the path+ name of UI

file is stored in the constant named "UI"

 

//Load the Glade file and instiate its widgets:

    Glib::RefPtr<Gtk::Builder> builder;

    try

    {

        builder = Gtk::Builder::create_from_file(UI);

    }

    catch (const Glib::FileError & ex)

    {

        std::cerr << ex.what() << std::endl;

        return 1;

    }

    Gtk::Window* main_win = 0;

 

Now, my question is this-

 

How to link the GTK Window variable declared above- "main_win" with the window in the UI file and initialise it to show everything? I am sorry if this sounds like a newbie question :)

Any help would be appreciated:)

 

Yours sincerely,

Arvind.
