Dear Rhino developers,
I am working on eto panel, and I have encountered a problem where it crashes on mac. On windows its working fine.
For presentation of problem as a base I have used this example by @dale:
I have changed code as below to update GridView values by clicking on hello:
using System;
using Eto.Drawing;
using Eto.Forms;
using Rhino.UI;
namespace SampleCsEto.Views
{
/// <summary>
/// Required class GUID, used as the panel Id
/// </summary>
[System.Runtime.InteropServices.Guid("0E7780CA-F004-4AE7-B918-19E68BF7C7C9")]
public class SampleCsEtoPanel : Panel, IPanel
{
/// <summary>
/// Provide easy access to the SampleCsEtoPanel.GUID
/// </summary>
public static System.Guid PanelId => typeof(SampleCsEtoPanel).GUID;
public GridView MyGridView = new GridView { ShowHeader = false, AllowColumnReordering = false, AllowEmptySelection = true, GridLines = GridLines.Vertical };
/// <summary>
/// Required public constructor with NO parameters
/// </summary>
public SampleCsEtoPanel(uint documentSerialNumber)
{
m_document_sn = documentSerialNumber;
Title = GetType().Name;
var myGridColumn1 = new GridColumn();
myGridColumn1.DataCell = new TextBoxCell(0);
myGridColumn1.Width = 32;
var myGridColumn2 = new GridColumn();
myGridColumn2.DataCell = new TextBoxCell(1);
myGridColumn2.Width = 53;
var myGridColumn3 = new GridColumn();
myGridColumn3.DataCell = new TextBoxCell(2);
myGridColumn3.Width = 40;
MyGridView.Columns.Add(myGridColumn1);
MyGridView.Columns.Add(myGridColumn2);
MyGridView.Columns.Add(myGridColumn3);
MyGridView.DataStore = new string[][]
{
new string[] { "test", "test1", "t3" },
new string[] { "test", "test1", "t3" },
new string[] { "test", "test1", "t3" },
new string[] { "test", "test1", "t3" },
new string[] { "test", "test1", "t3" },
new string[] { "test", "test1", "t3" },
new string[] { "test", "test1", "t3" },
new string[] { "test", "test1", "t3" },
};
var hello_button = new Button { Text = "Hello..." };
hello_button.Click += (sender, e) => OnHelloButton();
var child_button = new Button { Text = "Child Dialog..." };
child_button.Click += (sender, e) => OnChildButton();
var document_sn_label = new Label() { Text = $"Document serial number: {documentSerialNumber}" };
var layout = new DynamicLayout { DefaultSpacing = new Size(5, 5), Padding = new Padding(10), Width = 260 };
layout.AddSeparateRow(hello_button, null);
layout.AddSeparateRow(child_button, null);
layout.AddSeparateRow(document_sn_label, null);
layout.BeginGroup("test");
layout.AddSeparateRow(MyGridView, null);
layout.EndGroup();
layout.Add(null);
var scrollableLayout = new DynamicLayout();
scrollableLayout.BeginScrollable(BorderType.None);
scrollableLayout.AddCentered(layout, null, null, null, null, true, false);
scrollableLayout.EndScrollable();
Content = scrollableLayout;
}
private readonly uint m_document_sn;
public string Title { get; }
/// <summary>
/// Example of proper way to display a message box
/// </summary>
protected void OnHelloButton()
{
// Use the Rhino common message box and NOT the Eto MessageBox,
// the Eto version expects a top level Eto Window as the owner for
// the MessageBox and will cause problems when running on the Mac.
// Since this panel is a child of some Rhino container it does not
// have a top level Eto Window.
Dialogs.ShowMessage("Hello Rhino!", Title);
MyGridView.DataStore = new string[][]
{
new string[] { "hello", "hello1", "h3" },
new string[] { "hello", "hello1", "h3" },
new string[] { "hello", "hello1", "h3" },
new string[] { "hello", "hello1", "h3" },
new string[] { "hello", "hello1", "h3" },
new string[] { "hello", "hello1", "h3" },
new string[] { "hello", "hello1", "h3" },
new string[] { "hello", "hello1", "h3" },
};
}
/// <summary>
/// Sample of how to display a child Eto dialog
/// </summary>
protected void OnChildButton()
{
var dialog = new SampleCsEtoHelloWorld();
dialog.ShowModal(this);
}
#region IPanel methods
public void PanelShown(uint documentSerialNumber, ShowPanelReason reason)
{
// Called when the panel tab is made visible, in Mac Rhino this will happen
// for a document panel when a new document becomes active, the previous
// documents panel will get hidden and the new current panel will get shown.
Rhino.RhinoApp.WriteLine($"Panel shown for document {documentSerialNumber}, this serial number {m_document_sn} should be the same");
}
public void PanelHidden(uint documentSerialNumber, ShowPanelReason reason)
{
// Called when the panel tab is hidden, in Mac Rhino this will happen
// for a document panel when a new document becomes active, the previous
// documents panel will get hidden and the new current panel will get shown.
Rhino.RhinoApp.WriteLine($"Panel hidden for document {documentSerialNumber}, this serial number {m_document_sn} should be the same");
}
public void PanelClosing(uint documentSerialNumber, bool onCloseDocument)
{
// Called when the document or panel container is closed/destroyed
Rhino.RhinoApp.WriteLine($"Panel closing for document {documentSerialNumber}, this serial number {m_document_sn} should be the same");
}
#endregion IPanel methods
}
}
It looks like that when GridView is in âscrollableâ and in âgroupâ it crashes when I try to redefine its DataStore.
Could someone advice how to make it not crash on mac? I have problem to debug this on mac. Rhino 7 SR14
