ETO GridView rhino 8 and python 3

Scripting

Hi all,

Trying to create a simple ETO modeless dialog in Rhino 8 and Python 3 with a GridView.

I cannot seem to get the DataStore contents to render in the table. The data does exist, and adding a ClickEvent shows that data is stored in the element.

Minimal code example below, with the ClickEvent which prints cell content clicked to the Rhino commandline.

Any ideas to what I am doing wrong?

I did have to change the DataStore from a list of lists to a list of tuples to make it work from IronPython → Python3.

Works in p3:

GridTable.DataStore = [("UUID 1", "1"), ("UUID 2", "2")]

Doesn’t work in p3:

GridTable.DataStore = [["UUID 1", "1"], ["UUID 2", "2"]]

#! python3

@etiennekasteel Python 3 interops very differently with dotnet, in this case the dotnet Eto library. Currently the automatic casting to TreeGridItem does not happen correctly. I created a ticket so I can look into this: RH-82477 Python 3 implicit cast issue

For now create the tree items directly:

GridTable.DataStore = [
        forms.TreeGridItem(["UUID 1", "1"]),
        forms.TreeGridItem(["UUID 2", "2"])
    ]

And to grab value from column, use the .Values property of the tree items:

def OnCellClick(sender, e):
    if e.Item:
        rprint(e.Item.Values[e.Column])

Works like a charm! Thank you.
