Hi,

Is it possible to customize properties tab? I need to display user strings whenever I select the object.

Yes, it is possible to provide your own custom object properties pages.

From a RhinoCommon plug-in project, you will need to override the `ObjectPropertiesPages` virtual function, found on your plug-in object, and return one or more `ObjectPropertiesPage` objects.

Let me know if you need to see a sample…

I would appreciate a simple example.  
I will also need to use ComboBox, so if this also needs any special approach, It would be nice to see it. But with comboBox I hope I should manage by myself.

OK, I’m nearly there. Now I try to initialize this control, but I’m not sure what I need to provide to Initialize method? What kind of Rhino Object?

InitializeControls(RhinoObject rhObj);

I have also been trying to get this to work (sorry for hijacking the topic 😄) and have run into this problem:

Upon selecting an object in Rhino, I get a call to the overridden `ShouldDisplay` method. The `RhinoObject` that is received there is always `null`. So I cannot decide in this method whether the custom object properties page should be shown.

After making a run, clearly there isn’t enough exposed to properly add a page to the Object Properties panel. I’ll work with @stevebaer to see if we can get what we need in a future Rhino release.

How far did you get with this? The comments below don’t really close the discussion.

The work item on the bug tracker s still open, so I don’t think it has been fixed…

There is a Sample which seems to work: [https://github.com/dalefugier/SampleCsObjectProperties](https://github.com/dalefugier/SampleCsObjectProperties)

Use an object iterator with a filter for the object types that you care about to get the selected objects in InitializeControls. This will work as good if not better than the C++ functions that are not wrapped.

Would it be possible to achieve this entirely through Rhino.Python?

No, not at this time. These panels need to be associated with a compiled plug-in

@stevebaer, recently i´ve stumbled across [this](https://msdn.microsoft.com/en-us/library/aa302326.aspx) example using a PropertyGrid in a WinForm dialog which seems to work through Rhino Python. Below is a stripped down example:

```auto
import System
from System.Drawing import *
from System.ComponentModel import *
from System.Windows.Forms import *
    
class OptionsDialog(System.Windows.Forms.Form):
    def __init__ (self):
        OptionsPropertyGrid = PropertyGrid()
        OptionsPropertyGrid.Size = Size(280, 260)
        self.Controls.Add(OptionsPropertyGrid)
        self.Text = "Options"
        appset = AppSettings()
        OptionsPropertyGrid.SelectedObject = appset
    
class AppSettings():
    def __init__ (self):
        #[CategoryAttribute("MySettings"), DefaultValueAttribute(True)]
        self.SaveOnClose = True
    
d = OptionsDialog()
if d.ShowDialog() == DialogResult.Cancel:
    print "saveOnClose =", d.Controls[0].SelectedObjects[0].SaveOnClose
d.Dispose()

```

I´ve found a way to track `PropertyValueChanged` events to make it work in SemiModal way and to return results when the window is closed as shown above.

However setting simple things like `CathegoryAttribute()` or `DefaultValueAttribute()` are still a mystery. (see the comment in the code above). Can you please help with this and show an example how the `AppSettings()` class above has to look like ?

thank you,  
c.

I’m trying to write a script in Rhino 7, in EditPythonScript, that would set up my page  
to the Properties panel.  
But I can’t use the PlugIn.ObjectPropertiesPages function  
Is this even possible or not?

From a Python script, no. You’ll need to write a plug-in for this.
