This is a bug in atk, I would say. The role property should really be
defined as enum, not as int.
If that is fixed, then your ui file snipplet will start to work.

First as you said that and then I thought you needed to know about
GtkTreeModel widget

"The GtkTreeModel
 interface
defines a generic tree interface for use by the GtkTreeView
 widget. It is an
abstract interface, and is designed to be usable with any appropriate data
structure. The programmer just has to implement this interface on their own
data type for it to be viewable by a GtkTreeView
 widget."

for *bunches of those data, each in a different tab inside the same window.*

Finally, yes it's the same what I wanted you find in the Gtk document at
the first message from me to you.

FI, I have posted a patch implementing this in gtk on 

https://gitlab.gnome.org/GNOME/gtk/issues/109

Along the way, I found that there is



ATK_ROLE_STATIC



which is supposed to do the same, but that doesn't work:
"accessible-role" is supposed to be an int, not a string, and thus one
would have to put 117 there instead of ATK_ROLE_STATIC, which is really
going to work :)

So I'd say my proposal still make sense?

No, I didn't implement any Notebook yet. This was just to describe how

If I there is no use for any of the functionalyties of a Notebook, I 
won't use it just to get it's look and if I would, probably the cleanest

Also, TreeView has a set_model() method which lets you specify which model to

it back afterwards, works faster without needless redraws.


I will look into that.

Yo,

Have you tried removing the existing TreeView widget from one Notebook tab, and 
adding it (the same instance) to another when the user switches?

Also, TreeView has a set_model() method which lets you specify which model to 
use. For example, unset the model before making numerous data changes and set 
it back afterwards, works faster without needless redraws.

Whether this combination, compared to each tab having its own TreeView, helps 
you improve performance and resource usage or not, you'll need to test on your 
data. Please tell if it does.

Cheers,
Makepost

Yo,

Have you tried removing the existing TreeView widget from one Notebook tab, and 
adding it (the same instance) to another when the user switches?

Also, TreeView has a set_model() method which lets you specify which model to 
use. For example, unset the model before making numerous data changes and set 
it back afterwards, works faster without needless redraws.

Whether this combination, compared to each tab having its own TreeView, helps

Well, that's why you was wrong as I said, don't keep only one GtkTreeModel
for storing the data, I mean you should have multiple GtkTreeModels. Please
read again more detail in Gtk documents.

Re: Using a ButtonBox instead of a Notebook?

2018-03-19 Thread Bachsau 
I'm sorry, but I think I don't understand what you're trying to tell me, 
as I think this is how I already do it.


I have a working Application managing a bunch of data represented by a 
list of items with several attributes. These items are displayed to the 
user by using a GtkTreeView backed by a GtkListStore, to which I append 
those items.


Now I want to expand my application to manage not just one but several 
bunches of those data, each in a different tab inside the same window.


As I understand it, the GtkTreeView widget is really just a display 
element, taking all of its data from the GtkListStore. This is why I 
thought I could just create and keep a separate GtkListStore in memory 
for every bunch of data and assign them to the one GtkTreeView widget 
whenever the user clicks a button.
