 Post subject: how to check which child is in the container

Hey everyone,

the action of my toolbar buttons are dependent on the child widget in one of the containers (the button changes the child, for that I need to know which child to remove and which to add; at least this is the way I thought of).

How can I check which child is parented by the container? I know that there is a get_child method, but how can I compare the return value?

Thanks in advance

I don't understand what you mean: "dependent on the child widget in one of the containerS"
Normally a toolbar is in just one container like a vbox and each addition to the toolbar has an index which can be used to refer to that button. Could you post what code you have? Here's a modified example from
/* COMPILE WITH:  gcc -Wall -o tool1 `pkg-config --cflags --libs gtk+-3.0` tool1.c  */

#include <gtk/gtk.h>

int main( int argc, char *argv[])
  GtkWidget *window;
  GtkWidget *vbox, *toolbar;
  GtkToolItem *new, *open, *save, *sep, *exit;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
  gtk_window_set_default_size(GTK_WINDOW(window), 250, 200);
  gtk_window_set_title(GTK_WINDOW(window), "toolbar");

  vbox = gtk_vbox_new(FALSE, 0);
  gtk_container_add(GTK_CONTAINER(window), vbox);

  toolbar = gtk_toolbar_new();
  gtk_toolbar_set_style(GTK_TOOLBAR(toolbar), GTK_TOOLBAR_ICONS);

  gtk_container_set_border_width(GTK_CONTAINER(toolbar), 2);

  new = gtk_tool_button_new_from_stock(GTK_STOCK_NEW);
  gtk_toolbar_insert(GTK_TOOLBAR(toolbar), new, 0);

  open = gtk_tool_button_new_from_stock(GTK_STOCK_OPEN);
  gtk_toolbar_insert(GTK_TOOLBAR(toolbar), open, 1);

  save = gtk_tool_button_new_from_stock(GTK_STOCK_SAVE);
  gtk_toolbar_insert(GTK_TOOLBAR(toolbar), save, 2);

  sep = gtk_separator_tool_item_new();
  gtk_toolbar_insert(GTK_TOOLBAR(toolbar), sep, 3);

  exit = gtk_tool_button_new_from_stock(GTK_STOCK_QUIT);
  gtk_toolbar_insert(GTK_TOOLBAR(toolbar), exit, 4);

  gtk_box_pack_start(GTK_BOX(vbox), toolbar, FALSE, FALSE, 5);

  g_signal_connect(G_OBJECT(exit), "clicked",
        G_CALLBACK(gtk_main_quit), NULL);

  g_signal_connect_swapped(G_OBJECT(window), "destroy",
        G_CALLBACK(gtk_main_quit), NULL);

  return 0;
