i simply try to edit a ETO sample but other than changing the string i cannot understand the correlation from Layout and effect

Hi @s.branca,

Layouts are used to organize controls on your form. Eto includes a couple of different types of layout classes.

Here is some info on DynamicLayout.

You are missing a self.Content = layout.

Just creating a layout is not enough, you need to put it somewhere so it actually can show up.

import rhinoscriptsyntax as rs

import Eto.Forms as forms
commandname = “FindHole”

class SimpleEtoDialog(forms.Dialog):

def __init__(self):
    self.Title = "Sample Eto Dialog"
    self.ClientSize = drawing.Size(200, 200)
    self.Padding = drawing.Padding(5)
    self.Resizable = False
    layout = forms.DynamicLayout()
    self.content = layout
    
    ##it is not working either.... 4
    
    
    layout.Padding = drawing.Padding(5)
    layout.Spacing = drawing.Size(5, 5)
    layout.AddRow(forms.Label(Text ="i !"))
    layout.AddRow(forms.Label(Text ="am"))
    layout.AddRow(forms.Label(Text ="NOT"))
    layout.AddRow(forms.Label(Text ="WORKING!"))

Creating a dialog instance and displaying the dialog.

def TestSampleEtoDialog():
dialog = SimpleEtoDialog()
dialog.ShowModal(Rhino.UI.RhinoEtoApp.MainWindow)

Check to see if this file is being executed as the “main” python

script instead of being used as a module by some other python script

This allows us to use the module which ever way we want.

do you know more eto’s example beyond this one? https://developer.rhino3d.com/guides/rhinopython/eto-controls-python/#sample-dialogs

I have really used Eto only with F# and C#, but it should be pretty straightforward to learn from examples in those languages, then transform to information into Python versions.
