I am using gtk+ with c . I have created menu bar and now want to attach a table with some buttons. I have written all essential API routines but, problem I am facing is, if I first create menu bar then table is not rendered to window and it I render table first menu bar is not seen at its place.. .I don't know why. here is the code
/* Button Boxes
*
* The Button Box widgets are used to arrange buttons with padding.
*/
#include <gtk/gtk.h>
GtkWidget *window,*button,*container,*menubar,*fileM,*menu,*vbox,*aboutM,*quitM,*bdrM;

{

box=gtk_message_dialog_new(GTK_WINDOW(window),GTK_DIALOG_DESTROY_WITH_PARENT,GTK_MESSAGE_INFO,GTK_BUTTONS_OK,"EXAMPLE");;
gtk_dialog_run(GTK_DIALOG(box));
gtk_widget_destroy(box);
}
void Warning_quit()
{
GtkWidget *box;
box=gtk_message_dialog_new(GTK_WINDOW(window),GTK_DIALOG_DESTROY_WITH_PARENT,GTK_MESSAGE_WARNING,GTK_BUTTONS_YES_NO,"Sure want to quit..");
gtk_dialog_run(GTK_DIALOG(box));
gtk_widget_destroy(box);
gtk_main_quit();
}
void toggle_Border()
{
if(status==false)
{
gtk_window_set_decorated(GTK_WINDOW(window),true);
gtk_menu_item_set_label(GTK_MENU_ITEM(bdrM),"fix");
status=true;
}
else if(status==true)
{
gtk_window_set_decorated(GTK_WINDOW(window),false);
gtk_menu_item_set_label(GTK_MENU_ITEM(bdrM),"move");
status=false;
}
}

The problem is that you are trying to add more than one child to the same container, GtkWindow, which only can hold one child.
You did create a vbox but after you did not add the GtkTable, which by the way its deprecated since Gtk+ 3.4, to the GtkBox.
Also note that you are adding the GtkTable to the window before creation and GtkWindow will complain about that.
So, your initTable function should be:
void initTable()
{
GtkWidget *button;
button=gtk_button_new_with_label("button");
table=gtk_table_new(4,4,true); //table created..
gtk_table_attach_defaults(GTK_TABLE(table),button,0,1,0,1); //attaching frame container to table cell..
gtk_box_pack_start(GTK_BOX(vbox),table,0,0,1);//attach menubar with vbox//
}
In order to compile we had to define true, false and bool (due to the includes, not sure of which framework you are using).
