gtk-- problem :(

[Ronald Lembcke <es186 fen baynet de>]

Hi!

I hope this is the right place to ask (or does a gtk-- mailinglist exist?
than I'd ask there ... but didn't notice one till now...)

Ok... I just want a CList in a window with a few other widgets...

But it produces the following error, and I have no idea where it
comes from... :(

As this is my first program in gtk-- its quite possible that
there are some absolutly silly mistakes in it... but I don't see 'em

Oh... before I forget: gtk+ 0.99.10  gtk-- 0.7.18

When I start the program it say:
** WARNING **: invalid cast from (NULL) pointer to `GtkVScrollbar'
** WARNING **: invalid cast from (NULL) pointer to `GtkScrollbar'
** WARNING **: invalid cast from (NULL) pointer to `GtkRange'
** WARNING **: invalid cast from (NULL) pointer to `GtkWidget'
** WARNING **: invalid cast from (NULL) pointer to `GtkObject'
** ERROR **: sigsegv caught

The Program looks like this:

#include <glib.h>
#include <gdk/gdk.h>
#include <gtk/gtk.h>
#include <String.h>
#include <gtk--.h>

class TGameChoseWin : public Gtk_Window
{
	Gtk_VBox VBox1;
	Gtk_CList GameList;
	Gtk_HBox HBox1;
	Gtk_Button ExitButton;
	Gtk_Button StartButton;

	public:
	TGameChoseWin();
};

TGameChoseWin::TGameChoseWin()
	: Gtk_Window(GTK_WINDOW_TOPLEVEL),
	VBox1( FALSE, 5),
	GameList( 3),
	HBox1( TRUE, 0),
	StartButton( "Start"),
	ExitButton( "Exit")
{
	set_title( "StarEmpires - Gamelist");
	
	add( &VBox1);

	VBox1.pack_start( &GameList, TRUE, TRUE, 0);
	GameList.show();
	
	VBox1.pack_start( &HBox1, FALSE, FALSE, 0);

	HBox1.pack_start( &StartButton, TRUE, TRUE, 0);
	StartButton.show();
	
	HBox1.pack_start( &ExitButton, TRUE, TRUE, 0);
	ExitButton.show();

	HBox1.show();
	VBox1.show();
}

int main( int argc, char *argv[])
{
	Gtk_Main StarEmpires( &argc, &argv);

	TGameChoseWin *GameChoseWin;
	GameChoseWin = new TGameChoseWin();
	GameChoseWin->show();

	StarEmpires.run();

	return( 0);
}

Thanks in advance...
