Description pinggi 2012-06-02 11:40:03 UTC
Following app causes 'critical' output:

public void Run(string[] args)
	win = new MainWindow();


public partial class MainWindow: Gtk.Window
	public MainWindow() : base(Gtk.WindowType.Toplevel)

		this.AppPaintable = true;
		this.Colormap = Screen.RgbaColormap;

If the app is run, its window is opened and then closed immediately with the following output: 

(TestApp:1516): Gtk-CRITICAL **: gtk_widget_set_colormap: assertion `!gtk_widget_get_realized (widget)' failed

MainWindow is displayed because there is this.Show() method in the Build() method of the MainWindow class. It is generated by stetic designer or Gtk# project template.

Is that correct behaviour?
