I have an app creating a graph using Medsphere. The graph appears, at least the axes do, but no plot appears (although the vertical range appears to be what I expected.) And it crashes if I click on the graph:
Exception in Gtk# callback delegate Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception. System.NullReferenceException: Object reference not set to an instance of an object at Medsphere.Widgets.HistogramPlot.GetPlotPoint (TreeIter iter, System.Int32& x, System.Int32& y) [0x00000] at Medsphere.Widgets.HistogramPlot.GetGrabFocusRequest (System.Int32& x, System.Int32& y) [0x00000] at Medsphere.Widgets.Graph.OnFocusGrabbed () [0x00000] at Gtk.Widget.focusgrabbed_cb (IntPtr widget) [0x00000] at GLib.ExceptionManager.RaiseUnhandledException(System.Exception e, Boolean is_terminal) at Gtk.Widget.focusgrabbed_cb(IntPtr widget) at Gtk.Widget.gtk_widget_grab_focus(IntPtr ) at Gtk.Widget.GrabFocus() at Medsphere.Widgets.Graph.OnFocusInEvent(Gdk.EventFocus focus) at Gtk.Widget.focusinevent_cb(IntPtr widget, IntPtr evnt) at Gtk.Widget.gtksharp_widget_base_grab_focus(IntPtr ) at Gtk.Widget.OnFocusGrabbed() at Medsphere.Widgets.Graph.OnFocusGrabbed() at Gtk.Widget.focusgrabbed_cb(IntPtr widget) at Gtk.Widget.gtk_widget_grab_focus(IntPtr ) at Gtk.Widget.GrabFocus() at Medsphere.Widgets.Graph.OnButtonPressEvent(Gdk.EventButton ev) at Medsphere.Widgets.Graph2D.OnButtonPressEvent(Gdk.EventButton ev) at Gtk.Widget.buttonpressevent_cb(IntPtr widget, IntPtr evnt) at Gtk.Application.gtk_main() at Gtk.Application.Run() at MorrisonIndustries.IMAPAnalysis.App.Main(System.String[] args) Anyone seen this before? _______________________________________________ Mono-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-list
