关于GtkComboBox有点问题请教下

Question

如何获得GtkComboxBox的下拉框中光标点击（或光标所在）的下拉选项的内容？

Answer 1

#include <gtk/gtk.h>
char* arr[] = {"春季","夏季","秋季","冬季"};
char* eArr[] = {"Spring","Summer","Autumn","Winter"};
GtkWidget* lab;

void on_changed(GtkWidget *w, gpointer data)
{
int i = gtk_combo_box_get_active( GTK_COMBO_BOX(w) );
gtk_label_set_text( GTK_LABEL(lab), (eArr) );
}

int main( int   argc, char *argv[] )
{  int i;

  gtk_init(&argc,&argv);
  GtkWidget* win=gtk_window_new(GTK_WINDOW_TOPLEVEL);
  g_signal_connect(G_OBJECT(win),"destroy",G_CALLBACK(gtk_main_quit),NULL);

  GtkWidget* vb = gtk_vbox_new(0, 4);
  gtk_container_add (GTK_CONTAINER (win), vb);
  GtkWidget* cbb = gtk_combo_box_new_text ();
  for(i=0; i<4; i++) {
   gtk_combo_box_append_text(GTK_COMBO_BOX(cbb), (arr) );
  }
  gtk_box_pack_start (GTK_BOX (vb), cbb, FALSE, FALSE, 0);
  gtk_combo_box_set_active (GTK_COMBO_BOX(cbb),0);
  g_signal_connect (cbb, "changed", G_CALLBACK (on_changed), NULL);
  lab = gtk_label_new ("请由上面选择");
  gtk_box_pack_start (GTK_BOX (vb), lab, TRUE, TRUE, 0);

  gtk_widget_show_all(win);
  gtk_main();
  return 0;
}

看一下程序，领会一下吧。
