Add and Remove elements from Eto

[mikhail]

I have a Modeless form, and I want to change the contents of it to something else depending on what button is pushed.
I want this section over here to change to other things
lines (52-60)

		# Create a group box for atrButtons
		self.m_groupboxAtr = forms.GroupBox()
		self.m_groupboxAtr.Padding = drawing.Padding(5)

		groupLayoutAtr = forms.DynamicLayout()
		groupLayoutAtr.Spacing = drawing.Size(5, 5)

		groupLayoutAtr.AddRow(self.CreateAtrButtons())
		self.m_groupboxAtr.Content = groupLayoutAtr

it’s pulled by line 84

		layout.AddRow(groupLayoutPartNum, groupLayoutAtr)

When one of the buttons gets clicked I want to remove the groupLayoutAtr and push something else to display in that area.
I know what most of my work is going to happen in OnAtrButtonClick line 180, or AssignAttributes line 184
I just don’t know how to “unload” one group set so I can load something else in there…
I’ve changed everything to one icon file attached here. In case some needs to try and run the script.

But here is what it looks like on my end.

If anyone could nudge me in the right direction, that be much appreciated. I don’t expect anyone to do a full reworked code for me. I just posted my stuff so the conversation can be a bit more direct.
I’m sure I will need to move some stuff around. I just don’t really know where to even start on this one.
If someone has an example of simple form updating it’s button layout contents be awesome to see. It’ll help to start figuring out how to figure my stuff out.

[Trav (Travis Serio)]

If I follow along correctly it sounds like you just need to set yourself up panels that have each “section” of controls that you want to display. Then simply have a main panel on the right side of your form where you can change its Panel.Content = SomeOtherPanel when your buttons are pressed. Hopefully that makes sense.

[mikhail]

@Trav Thanks for some information.
I was trying to look up panel stuff and it seems like the links are broken for that
Goes to 404
https://github.com/picoe/Eto/blob/develop/Source/Eto/Forms/Controls/Panel.cs
from this article

Eto Layouts in Rhino.Python

and from this one as well

picoe/Eto

Do you know if there is any documentation or a small example on this somewhere else? Be nice if it was in python. But beggars can’t be choosers. I’ll take whatever I can get at this point.

[Trav (Travis Serio)]

Lots of controls can perform as a panel. In your case you can use the GroupBox like you already are as your panel. Its just a container for your controls.

[mikhail]

@Trav Thank you for the nudge!
Just got it working.
Not sure if that’s the best way to do it. I’m sure there is some other better way to do it. But I think it’s going to work for me.
If anyone is looking for same type of solution here is what I did

part of Initialize triggers displayMainPanel() which calls self.panelToShow()
It looks to see what self.showPanel is set to, and pull up a corresponding layout.
And that get’s triggered by OnAtrButtonClick().
So with a button press I am recalling the displayMainPanel()
at the start of the script I have self.showPanel set to a default value, and after OnAtrButtonClick() it changes it to something else. And OnOkButtonClick() I set that value back to default.

Hope it makes sense…
