How to use gtk combo box

You know that how to place widgets on the window in glade. So I will demonstrate to setup combo box directly.

Step 1:

Step 2:

After clicking new glade will add liststore in your window

See example below

Step 3: click on the liststore1

After doing this you will see like you see in below image

 

Step 4:

Step 5:

Step 6:

When you click add button in the above window

Then do like in below image

Now close this window and save the work.

Now the coding part.

#include <stdlib.h>

#include <gtk/gtk.h>

#include <string.h>

struct window

{

   GtkComboBox *cb;

   GtkLabel *l;

};

typedef struct window Widgets;

Widgets Widg;

G_MODULE_EXPORT void on_GetAndSet_clicked ( GtkButton *button,Widgets *widg)

{

   const gchar *text = gtk_combo_box_get_active_text( widg->cb );   // getting text from the combo box

gtk_label_set_text(Widg.l,text); /*setting or you can say putting text on the label so that you can se                                                                                                                                                                         

                                                           what you have selected in the combo box*/    

}

// and till from the beginning of gtk tutorial now you obviously know what to do in the main now I will not comment below code. J

int main(int argc, char *argv[])

{

    GtkBuilder *gtkBuilder;

    GtkWidget  *win;

    gtk_init(&argc, &argv);

    gtkBuilder = gtk_builder_new();

    gtk_builder_add_from_file(gtkBuilder, "cb.glade", NULL);

    win = GTK_WIDGET( gtk_builder_get_object( gtkBuilder, "window1") );

    Widg.cb = GTK_COMBO_BOX( gtk_builder_get_object( gtkBuilder, "combobox1" ) );

    Widg.l = GTK_LABEL( gtk_builder_get_object( gtkBuilder, "label" ) );

    gtk_builder_connect_signals( gtkBuilder,&Widg );

    g_object_unref(G_OBJECT(gtkBuilder));

    gtk_widget_show(win);

    gtk_main();

    return 0;

}
