[Gtk-sharp-list] Removing all the widgets from a table Mac OSX GTK#

[Billy Schoenberg]

Hey,

Thanks for the response. I do not think the code I use to reattch them is an
issue, but I have attached it below.  The reason I do not think its an
issues is because if i comment out those lines I showed you last e-mail the
program does not crash, it just piles widgets on top of each other.  Also
this code works just fine on Windows (all versions) and Linux (SUSE and
Ubuntu) I use the "Native Version" of GTK on OSX 10.5 with Mono 1.9.1 that I
installed 3 or so months ago.  Do you have any ideas about a work around,
another way to remove widgets from a table?

 public override void LayoutPropertiesPanel()
        {
            if(showPropPanel)
            {

                Table GTKTable =
drawView.Controller.GTKObjectPropertiesTable;

                GTKTable.Attach(typeIndicator, 1, 4, 2, 5);
                GTKTable.Attach(nameBox, 1, 4, 6, 8);

                GTKTable.Attach(xLabel, 4, 6, 2, 5);
                GTKTable.Attach(xBox, 4, 6, 6, 8);


                GTKTable.Attach(yLabel, 6, 8, 2, 5);
                GTKTable.Attach(yBox, 6, 8, 6, 8);

                GTKTable.Attach(widthLabel, 4, 6, 9, 12);
                GTKTable.Attach(widthBox, 4, 6, 12, 14);

                GTKTable.Attach(heightLabel, 6, 8, 9, 12);
                GTKTable.Attach(heightBox, 6, 8, 12, 14);

                GTKTable.Attach(buttonModeCheckBox, 8, 12, 11, 15);

                GTKTable.Attach(fillLabel, 8, 10, 2, 5);
                GTKTable.Attach(fillButton, 8, 10, 6, 8, AttachOptions.Fill,
AttachOptions.Expand, 0, 0);

                GTKTable.Attach(strokeLabel, 9, 13, 2, 5);
                GTKTable.Attach(strokeButton, 10, 12, 6, 8,
AttachOptions.Fill, AttachOptions.Expand, 0, 0);

                GTKTable.Attach(strokeWidthLabel, 12, 15, 2, 5);
                GTKTable.Attach(strokeComboBox, 12, 15, 6, 8,
AttachOptions.Fill, AttachOptions.Expand, 0, 0);
                if ( showEvents )
                {
                    GTKTable.Attach(eventsLabel, 15, 18, 2, 5);
                    GTKTable.Attach(eventsComboBox, 15, 18, 6, 8,
AttachOptions.Fill, AttachOptions.Expand, 0, 0);

                    eventHandlerBox.BorderWidth = 1;
                    GTKTable.Attach(eventHandlerBox, 18, 31, 2, 15);
                    eventHandlerBox.GdkWindow.Background = new Gdk.Color(0,
0, 0);
                }

                GTKTable.ShowAll();
                UpdatePropertiesPanel(); // sets all of the values of the
widgets we just attached
            }
        }
