Cancel and Ok buttons in Eto form

RogerD · February 19, 2025, 7:29pm

Hi All,

I have been working on a python 3 script with multiple drop down boxes, I have been assisted by Callum and Curtis and now I have the drop downs working with my dictionary.

As this is not written in my usual format which my poor head can follow I find myself struggling to get a Cancel and Ok button on the form and upon clicking “OK” I want to return each of the four drop down list items selected a= dd1, b=dd2, etc.

I have inserted the script as I cannot download a PY3 file, all help appreciated

#! python3

I haven’t done anything with eto forms, but I found these guides that might be helpful:

RogerD · February 19, 2025, 8:34pm

Thanks Measure,

Read both but my lack of knowledge is the greatest barrier, I can do it when I stick to my usual way of writing code but Callum did the basics different and I find it hard to integrate my approach with his.
Roger

CallumSykes · February 19, 2025, 9:06pm

It seems this is the root of the issue then! It’s very important to understand code you are maintaining. I hoped to be helpful but it seems I’ve left you with a jigsaw puzzle without all the pieces.

How might you write this yourself, what is different between your style and mine?

RogerD · February 19, 2025, 9:51pm

Hi Callum,

As you will see from this example I am a little more regimented in my approach as this was the layout of the first and only ETO example I could find at the time and based on this I have normally achieved what I need . Your approach was a lot more compact and due to the nature of linking the drop down boxes of which I had no experience I really appreciated the help but it left me then trying to get my head around the last two issues the ok and cancel buttons and the getting of the values when the ok button is picked.
Just different ways we would go about things.
The good news is that I now have the drop down boxes exactly as I needed them, just need to get to the output.

Hi Callum,

I now have the buttons showing in the form but keep getting errors on the

dialog.AbortButton.Click += dialog.OnCloseButtonClick

‘Dialog’ object has no attribute ‘OnCloseButtonClick’

so slowly getting to the end just need to resolve this and get the values from the dd lists.

If you move this section,

        # Close button click handler
        def OnCloseButtonClick(dialog, sender, e):
            dialog.Close(False)
    
        # OK button click handler
        def OnOKButtonClick(dialog, sender, e):
            dialog.Close(True)

above this,

        dialog.AbortButton.Click += dialog.OnCloseButtonClick

and change it to this,

        dialog.AbortButton.Click += OnCloseButtonClick

It then runs nicely for me
