Yes I think so. Legend, dock, icon problems are linked to the toolbar.
I've seen Thuban on Win and Linux. The toolbar is integrated with
menu in this way. Only 1 window (WINDOW A) with this sequence:
- Menu (row 1 of WINDOW A)
- Toolbar (row 2 - icons on WINDOW A)
- Legend + Display (row 3 new window, WINDOW B + WINDOW C nested in WINDOW A)
I have built Thuban also in FINK with X11 (OS X is Unix) and it works
with all icons like Win and Linux: there is 1 window only.
But in OS X native (not X11) the gui is different. I have not 1
window only but the menu go up and it is broken from the rest and
toolbar goes out. I have:
- Menu (always up, not in a window)
- Toolbar (missing because it doesn't find WINDOW A for icons)
- Legend + Display (row 3 new in a window, WINDOW B + WINDOW C)
The resizing problem is linked to this one: WINDOW A is not present.
The map work because they are on WINDOW C
In OSX the Toolbar must to go on a new window (row 1) and below
Legend window + Dispay window (row 2)

Now wxpython on Mac is 184.108.40.206
wxWindows is 2.5.3
but I have used:
wxpython on Mac 220.127.116.11
In Thuban OS X the only problems are in quantiles and toolbar
Your workaround for quantiles is good and it works.
I have seen the demo files in 2.4.2 and they work in OS X.
Example: pysketch is interesting
Inside the samples/pySketch folder I have entered in terminal:
% pythonw pySketch.pyw
and the program is started without problems:
the menu is up and I have a window with:
- row 1: 7 icons (toolbar)
- row 2: icons at left and display at right
Thuban is would be like this one (in OS X version)
Inside the pysketch code:
> # Setup our menu bar.
> menuBar = wxMenuBar()
> self.fileMenu = wxMenu()
> self.fileMenu.Append(wxID_NEW, "New\tCTRL-N")
> self.fileMenu.Append(wxID_OPEN, "Open...\tCTRL-O")
> self.fileMenu.Append(wxID_CLOSE, "Close\tCTRL-W")
> # Create our toolbar.
> self.toolbar = self.CreateToolBar(wxTB_HORIZONTAL |
> wxNO_BORDER | wxTB_FLAT)
row 2 (left side)
> # Setup our tool palette, with all our drawing tools and option icons.
> self.toolPalette = wxBoxSizer(wxVERTICAL)
> self.selectIcon = ToolPaletteIcon(self.topPanel, id_SELECT,
> "select", "Selection Tool")
> self.lineIcon = ToolPaletteIcon(self.topPanel, id_LINE,
> "line", "Line Tool")
> self.rectIcon = ToolPaletteIcon(self.topPanel, id_RECT,
> "rect", "Rectangle Tool")
Now Thuban code in Thuban/UI/mainwindow.py
># Map menu
>_method_command("map_projection", _("Pro&jection..."), "MapProjection",
> helptext = _("Set or change the map projection"))
>_tool_command("map_zoom_in_tool", _("&Zoom in"), "ZoomInTool", "ZoomInTool",
> helptext = _("Switch to map-mode 'zoom-in'"), icon = "zoom_in",
> sensitive = _has_visible_map)
>_tool_command("map_zoom_out_tool", _("Zoom &out"), "ZoomOutTool",
> helptext = _("Switch to map-mode 'zoom-out'"), icon =
> sensitive = _has_visible_map)
The icons are with menu because they go on WINDOW A but this is wrong
for OS X. WINDOW A is not present.
The source code like pysketch is good for the total compatibility

This is the method.
I have installed in OS X 10.3 (Python 2.3 is included):
- XCode 1.5 (Developer software free from Apple http://connect.apple.com)
- addon for Python 2.3 for Panther
- wxWindows 2.4.2 for the Mac (http://www.wxwindows.org/)
(it's old but now it's better for Thuban)
- wxPython on Mac 18.104.22.168 for Python 2.3 (http://www.wxpython.org/)
(it's old but now it's better for Thuban)
- SQLite 2.8.15
- PySQLite 0.5.1
- Proj 4.4.9 (installed in /usr/local/thubanlib)
- GDAL 1.2.5 (built without python and installed in
/usr/local/thubanlib and after the I have built python module)
- PostgreSQL + PostGIS (7.4.3 + 0.8.1)
- mxDateTime 2.0.5 (http://www.egenix.com/files/python/mxDateTime.html)
- Pyscopg 1.1.14 (http://www.python.org/topics/database/modules.html)
this is a bit complex because it requires a folder
/postgresql-7.4.1/src/include/catalog/ not present in binary
PostgreSQL. You must build PostgreSQL + PostGIS and after you must
copy this folder on your bin build:
% cp -r /src/postgresql-7.4.1/src/include/catalog/ /usr/local/pgsql/include/
After you can build Pyscopg 1.1.14 with:
in setup.py you must change the path for proj, gdal_config and wx.
Now Thuban is built like a normal UNIX app in /usr/local/lib/thuban
and I can open it from terminal .... but I want an OS X program with
a simple double clic and with all libs linked internally.
There are many and many libraries linked to Thuban.
I have an help as you seen on my ReadMe file:
- py2app (http://undefined.org/python/#py2app)
It's like py2exe in Win and it's fantastic.
Drag and drop and I have created in 5 sec an app with some libs linked.
It doesn't run ....
Now inside the package I have seen the code and I have entered in
some folders all wx and wxpython needs for Thuban. I check the code
and I have seen that the only external libs need for Thuban are:
- libwx_mac-2.4.*.dylib and libwx_mac_gl-2.4.*.dylib (4 files + 4 sym
links) installed in /usr/local/lib;
- proj and gdal installed in /usr/local/thunalib (new folder creates from me)
This libs don't overwrite libs installed in OS X. If you have newer
versions of wxPython or wxWindows you can use them because they have
Inside the package there are all python extensions and other libs
need for Python.
I wanted to build a simple app without installer but I must install
these few libs and I have create a double clic pkg file for all users
without external download. (DMG file is 17 MB compressed but the app
is about 50 MB and the libs in /usr/local about 11 MB)
- mac package is different from other platforms because it doesn't
require external download. Normal user wants a simple app with a
double clic on file and thuban do it. I do a double clic on .thuban
file and it is opened in Thuban;
- you can change the Thuban code inside the package (eg: your
workaround on Quantiles is easy to apply in Thuban: see
- it always work with any other libs installes from other software
because it uses only few external libs in a new directory thubanlib.
What I want to see on Thuban:
- better raster support (eg geotiff loaded as mosaic: now every
raster delete the raster below);
- gdal-ogr support;
- grass support (raster-vect);
- text label more easy (now I must enter the label one by one);
- printing better (SVG now is good but not for all users);
- importAPR (it's a fantastic idea - this a big step for many users)
NOTE FOR JAN
Notes are wrong on
http://thuban.intevation.org/download.html#bin_macosx. The notes are
Please first read the file ReadMe inside the package
Mac OS X 10.3 or higher is required (Python 2.3 is included in OS X 10.3)
Thuban is built in OS X and it's fast. It's a normal Mac app and it
opens .thuban file with a simple double click and inside the ReadMe
file you can see how to load the extensions.
Toolbar is not present but you can select the same commands from Map menu.
Quantiles class not work.
Sometime Legend window is locked: exit and reopen Thuban and after
press the button "UnDock" in the Legend window.
Bye and good work
