Hi Guys,


I'm playing with GTK on Ubuntu, trying to make a simple text editor. I've got a window, it's very pretty.


Unfortunately, I've been trying to add some widgets to this window and I can't seem to make them show up.


I've no idea why they're not showing up.. perhaps someone could shed some light on this for me?

The following code should illicit a window complete with menu bar, textview in a scrolled container, and a status bar - it illicits an empty window:


#include <gtk/gtk.h>

int main ( int argc, char *argv[] )
	/* I want a Window with a vertical box layout */

	GtkWidget *window;
	GtkWidget *verticalLayout;

	/* Also, I want a scrollable textview */

	GtkWidget *textview;
	GtkWidget *scrollable;

	/* And a status bar, and a menu bar */
	GtkWidget *menu_bar;
	GtkWidget *status_bar;
	GtkWidget *file, *edit, *tools;

		Initialise GTK et al

	gtk_init (&argc, &argv);

	/* Give window*/
	window = gtk_window_new( GTK_WINDOW_TOPLEVEL );
	gtk_window_set_title( GTK_WINDOW( window ), "Editor" );
	gtk_window_set_position( GTK_WINDOW( window ), GTK_WIN_POS_CENTER);
	gtk_window_set_default_size ( GTK_WINDOW( window ), 600, 400);
	verticalLayout = gtk_box_new( GTK_ORIENTATION_VERTICAL, 2 );
	gtk_container_add(GTK_CONTAINER( window ), verticalLayout);
	/* Give Menu Bar */
	menu_bar = gtk_menu_bar_new();
	file = gtk_menu_item_new_with_label("File");
	gtk_menu_shell_append(GTK_MENU_SHELL(menu_bar), file );
	gtk_box_pack_start(GTK_BOX(verticalLayout), menu_bar, FALSE, FALSE, 3 );
	/* Give textview */

	textview = gtk_text_view_new();
	scrollable = gtk_scrolled_window_new(NULL, NULL);
	gtk_container_add( GTK_CONTAINER( scrollable ), textview ); // text view in scrollable
	gtk_box_pack_start( GTK_BOX( verticalLayout ), scrollable, TRUE, TRUE, 5 ); //scrollable in vbox

	/* Give Status Bar */
	status_bar = gtk_statusbar_new();
	gtk_box_pack_end( GTK_BOX(verticalLayout), status_bar, TRUE, TRUE, 3 );

	/* Connect the destroy signal to the x button callback */
	g_signal_connect( window, "destroy", G_CALLBACK (gtk_main_quit), NULL );

	/*	To Do - add other callbacks */

		Show the window
	gtk_widget_show (window);

		Enter the main() of the window and process callbacks as 
		they happen
	gtk_main ();

	return 0;

Thanks in advance,
