I've been doing something like this for wxIDE. Opened files are displayed in a tree form using directories. As files are opened or closed, the tree is updated accordingly. The implementation is in:

http://sourceforge.net/p/wxeuphoria/ide/code/ci/default/tree/files.e

Some of the work is done by wxWidgets and the wxTreeCtrl. Some of the important routines in that file regarding the tree manipulation:

• create_tree_path
• get_children
• reparent
• add_file
• remove_file_from_tree

You can, of course, see it in action if you download it. Although you might need to build wxEuphoria / wxWidgets yourself on Linux.

The version I'm using with wxIDE is a bit more bleeding edge. It actually uses wxWidgets 2.9. They have basically the same dependencies, but differences in gcc and other library versions could mean that the uploaded binaries won't work for you. It was build on Kubuntu 12.04. I upgraded recently to 13.04, and those binaries still work for me, but I'm not familiar with CrunchBang.

To install wxEuphoria on Linux or FreeBSD: 

Those are old instructions. You should be configuring your include paths using eu.cfg with 4.0+. If you need to build wxEuphoria yourself, download this tarball of wxEuphoria code.

There are instructions in the readme (and please ask if you need help):

To build wxEuphoria on Linux: 
 
* Download the latest wxWidgets 2.9 source from www.wxWidgets.org, or 
  install wxWidgets 2.9.x using your package manager (in which case, 
  you can skip the next two steps of building the wxWidgets binaries) 
   
   
* Dependencies:  You must have the following packages installed in order 
  to build wxEuphoria from source: 
      * libwxgtk2.9-dev 
      * gtk+-2.0-dev 
      * libpango1.0-dev 
* On a Debian based system you can do: 
  # agt-get build-dep libwxgtk2.8-0 
  (or whatever version of wxWidgets is in your package manager) 
 
* From the base directory where you decompressed wxWidgets, type: 
 
   $ ./configure --enable-monolithic --enable-mediactrl --enable-unicode --enable-shared \ 
    --disable-stc --disable-debug VENDOR=eu 
   $ make 
   $ make install 
 
* The binaries will be moved to a system directory.  You may need to 
  run ldconfig (or /sbin/ldconfig) on the directory where the binaries 
  were installed. 
 
* From the wxEuphoria source directory, type: 
  $ ./configure path/to/wxWidgets 
  $ make 
  $ make install 
 
* The shared library will be moved to a system directory.  You may need to 
  run ldconfig (or /sbin/ldconfig) on the directory where the binaries 
  were installed (should be /usr/local/lib).

If you have issues running wxEuphoria ("library not found", etc.) make sure you run ldconfig on the library:

sudo ldconfig /usr/local/lib/libwxeu.so.16 

Also, mind your bitness. If you're running a 64-bit distro, you should probably move to Euphoria 4.1 (still in development) and Matt's bleeding-edge 64-bit wxEuphoria binaries.

Also, because it's not clear from your messages, did you try downloading and running wxIDE v0.8.2? It comes with precompiled versions of wxWidgets and wxEuphoria, so it may all work for you. It also comes with a bleeding edge euphoria and translator (from the code branch with the experimental memstruct support).

Alternatively, you could try the Windows versions, if only to play around with. The 32 and 64-bit versions both run under WINE.

Um, well... I wrapped wxHtmlListBox into wxEuphoria last year, so if you are using Matt's bleeding-edge build (from wxIDE), it should be included. That would allow you to create a list of that style. You just have to use add_item() with simple HTML content.

I've also worked separately on wrapping wxFlatNoteBook which would allow you to create those colored tabs. I'll see if I can dig it out and get it posted. It's a separate library build I've been working on called wxEuphoria-Contrib.

As promised, here's a picture of a todo-list in EuGTK, along with source code. https://sites.google.com/site/euphoriagtk/

It's pretty easy to do, the complete interface is only < 150 lines of code (I didn't write the functions to connect and manage a database).

Which brings up a point: people keep asking for a GUI 'designer', but considering that a designer isn't going to automagically write the Euphoria code to manage the data, reading files, etc... that means that a designer is only going to do a small portion of the work required for building a real app. Which is why I haven't put much effort into writing one.

hahaha! That's a great to-do list! :D
