Eto OnKeyDown issue

My KeyDown seems to be ineffective. It seems that I have done something wrong.

#! python 3

import Eto.Forms as ef
import Eto.Drawing as ed
import Rhino as rh


class From(ef.Form):

    def __init__(self):
        super().__init__()
        self.Size = ed.Size(200,200)

        self.KeyDown += self.OnKeyDownEvent

    def OnKeyDownEvent(self,sender, e):
        try:
            print(f"Test:{e.Key}")
        except Exception as ex:
            rh.RhinoApp.WriteLine(f"Error in OnKeyDown: {ex}")


if __name__ == "__main__":
    form = From()
    form.Show()

You may need to click on the form or give it focus.

Adding this to the __init__ means I don’t need to click it first.

self.Focus()

I made the following modifications to this, but my “KeyDown” still cannot monitor keyboard information.

#! python 3

import Eto.Forms as ef
import Eto.Drawing as ed
import Rhino as rh

class From(ef.Form):
    def __init__(self):
        super().__init__()
        self.Size = ed.Size(200,200)
        self.Focus()

        self.KeyDown += self.OnKeyDownEvent
        self.MouseEnter += self.OnMouseEnterEvent

    def OnKeyDownEvent(self,sender, e):
        try:
            print(f"Test:{e.Key}")

        except Exception as ex:
            rh.RhinoApp.WriteLine(f"Error in OnKeyDown: {ex}")

    def OnMouseEnterEvent(self,sender, e):
        try:
            print("MouseEnter")
            self.Focus()

        except Exception as ex:
            rh.RhinoApp.WriteLine(f"MouseEnter: {ex}")

if __name__ == "__main__":
    form = From()
    form.Show()

Huh, on Windows this doesn’t capture any keys. I did the earlier one on Mac assuming they’d be identical. Not sure why right now, I’ll keep testing.

@curtisw would know for certain.

Hi @tom33 ,


import Eto.Forms as ef
import Eto.Drawing as ed
import Rhino

class MyForm(ef.Form):

    def __init__(self):
        super(MyForm, self).__init__()
        self.Title = "Key Test"
        self.Size = ed.Size(200, 200)
        
        drawable = ef.Drawable()
        drawable.CanFocus = True
        drawable.KeyDown += self.OnKeyDownEvent
        self.Content = drawable

    def OnKeyDownEvent(self, sender, e):
        Rhino.RhinoApp.WriteLine("Key pressed: {0}".format(e.Key))
        e.Handled = True

if __name__ == "__main__":
    form = MyForm()
    form.Owner = Rhino.UI.RhinoEtoApp.MainWindow
    form.Show()

Hope this clarifies any doubts,
Farouk
