Django is good for many projects, and I guess I’ll continue using it for 
websites, since my workflow is comfortable enough.

But for "desktopy" web apps, where most of the coding is in JS on the Client UI 
anyway, Meteor/Angular/React seems to be the better framework. I’m still at the 
beginning of my node.js journey, but I hit too many blocks while trying to do 
my current project in Django. And using dabo, i.e. installing an app on every 
user’s computer, would be a promise for a support desaster.
I used dabo only ever as a convenient UI framework, never really needed the 
3-tier setup. I could stay on Python 2.7, but I found the availability of 
dabo’s documentation too unreliable.

I hear you – for web apps I’m leaving my beloved Python/Django behind for 
Meteor/Angular (i.e. also node.js).

This is most probably unneccessary if not utter nonsense - with Latin-1 (ISO 
8859-1) you’ll get problems next time if you need Eastern European (Latin, 
Greek or Cyrillic) characters. It doesn’t even contain the € sign (you might 
use 8859-15).
Did you try 'utf-8'?

Or did you just forget that Python < 3 needs the unicode marker in front of 
strings?
like this: u'fiëé visuëlle'
And that you need to define the encoding of your Python files in a comment in 
the first few lines?
like this: # -*- coding: utf-8 -*-

(I’m currently not using dabo any more, so I didn’t try if that’s enough.)

 Hi, I am intending to create a desktop application as volunteer work for a 
 free clinic in Africa, and since there is no internet over there, I decided 
 to search for a tool I can use. I stumbled on this tool and I have some 
 questions to ask before I carry on with the project please.

Welcome!

 QUESTION: Can I create an application that has user authentication(user 
 registration just like any web app) and store patient data with dabo (because 
 we would be dealing with health records)?

Without network connection, user *registration* like any web app
makes no sense.
Of course you can build an app with user authentication, hooking into
dabo’s own mechanism or building your own.

2, can  I have access to tutorials that can enable me reach this goal (videos 
if possible but any would do)?

Did you browse dabo’s homepage at all? There’s a big fat link to
Documentation: http://dabodev.com/documentation

You absolutely need an Unicode-enabled wxPython!

 In my Python novice code I always write this line: # -*- coding:

I would never use 8-bit encodings any more. Better use UTF-8 (or plain

But anyway, the encoding line must fit your real text encoding - you  
should be able to set that in your editor.

Re: [dabo-users] cascading dropdown controls selections

[Henning Hraban Ramm]

Am 2011-04-07 um 17:06 schrieb John Fabiani:
 No that's right - I will be using OnHit.  But the problem is not as  
 straight
 forward as you suggest.  If I set the first dropdown the second,  
 third, and
 forth must match.  If I set the second the third and forth data  
 choices must
 match what is in 1 and 2  - and so on.  If I set all of them and  
 then change
 the first then all the rest must change.  To make matters worse none  
 of the
 data items come from the same tables.  Each dropdown filters the data
 available for the next.  And remember I want this to work with Dabo's
 DataSource and DataFields when not entering data into a new record.

 I have considered creating a view and then actually filter the data as
 required since the records are related but then I could have several  
 thousands
 of records in memory.  So I have discounted that solution.

 I have considered creating a class that would provide a dynamic  
 property that
 could be set to retrieve the data (choices and keys).  Similar to  
 the ones Ed
 and Paul have created for other controls.  Not sure how much work  
 this would
 be?

 I have considered creating a single method that all dropdowns call  
 and control
 the data in the method.  I would be able to read the values (keys)  
 from each
 of the controls and do what is required to reset the choices for  
 each of the
 controls.  This might be the way to go.

 But I looking for suggestions - from the list.  I don't want to  
 start a lot
 coding only to later discover I'm traveling along the wrong path.

The other suggestion of disabling not-yet-set dropdowns is probably  
good.

You could use events/signals to update all DDs in need.

Most easy is probably to update DD2 from DD1.onHit, update DD3 from  
DD2.onHit etc.
(only the next one, not more, except if there’s a high probability  
that the user wants a default value)
and perhaps reset all following DDs (in case someone changes the  
selection of DD1 after setting DD3).

In my similar case, I try to keep the selection of following DDs,  
since some selection-cascades are very similar, and it’s annoying to  
choose the same over and over if you’re exploring possibilities.

But in my case I don’t use Dabo’s bizobjs, but have read all the data  
from an http/JSON call and keep it in memory for the runtime (it’s not  
so much, only lists of sections and subsections for several magazines).

Sorry for being of no big help.

 Anyhow, thanks for the offer.

 Which of the two did you find better?


I generally like O’Reilly books - they’re normally a good read, no  
fuss. But it’s a matter of taste.
The Kochbuch (cookbook) didn’t tell me new tricks, as far as I looked  
into it (got it for a colleague who wanted to do some web development,  
but never came to it).
Most books of O’Reilly’s kurz  gut series (I guess it’s pocket  
reference in English) are good short references, not for learning. I  
got a lot of them, but in fact I normally find online references more  
handy and faster to use.
And even for learning new stuff (my about 13th programming language is  
Lua...) I prefer online material with a hands on approach, except  
for more fundamental subjects like design patterns. Books on computer  
subjects are always outdated...

directly, you don't need to know about those getters and setters, and  
at least a link to them and the parent class where they come from  
would be nice - but as far as I looked, there's nowhere any docs about  
that methods.
Do you think you can fix that?

 +1 from me. I'll give you commit access if you want to make the

 which would have a higher likelihood of getting it done probably!

I wonder where this French docstring comes from:

BaseClass

La classe Dabo de base de l’objet. Lecture uniquement. (classe)

Inherited from: dObject module


(Of course, it comes from dObject, but why French?)


 Thanks for all your work on this.

Sorry, I overlooked that the properties I bitched about came from wx,  
so I hope they'll just disappear ;-)

 Look at what you got from svn!
 The Framework code is in dabo/dabo. Only the Framework directory
 has to be linked into the python site-packages tree.
 If you link the outer dabo directory, you didn't link to the  
 framework
 one.

 somethink like:
 /opt/dabo - http://svn.dabodev.com/dabo/trunk/
 /opt/dabo/dabo - trunk/dabo

BTW, instead of linking, the Python way would be a dabo.pth file in  
your site-packages directory, containing only the path to dabo's  
parent directory.

You might not believe it, but I really *like* writing docs. Since  
there's so much documentation in dabo's code, I guess you also don't  
really hate it  :-)
Unfortunately dabo's wiki is rather untended - and even in my home

too much left to do, despite an active community...

And I wanted to open source my dabo-based tool-kit for a long time,

useful...

Enough moaning, back to work.

Ok, now I understand a bit more:
(At least) Sphinx must be able to import all classes, and that can't  
work without some setup (e.g. loading an UI).
I always get TypeError: Error when calling the metaclass bases
Source RSt files and setup attached.

I tried pydoctor (made for Twisted), because that doesn't import your  
code.
It expects epytext formatting and thus gives a lot of warnings that  
one can ignore.
Of course it can't put uiwx classes into ui.
Otherwise it works rather well, as long as I only point it at  
subdirectories (biz, lib, db, ui).
On dabo root I get AttributeError: 'Module' object has no attribute  
'subclasses' - that seems to be some problem of the tree builder.

Doxygen looks promising, but the output just isn't as handy as that of  
the other solutions, perhaps it's too much C- and Java-oriented and  
has too much overhead.
I didn't much try to tweak it, maybe there's potential (see attached  
cfg). Out of the box it doesn't really understand dabo's i18n'ed  
docstrings (I question the importance of i18n for docstrings, though.)  
and expects its own formatting (like JavaDoc, I guess).

With Epydoc you can choose whether to import or just parse the classes.
I get a lot of warnings like Warning: Module dabo.dPref is shadowed  
by a variable with the same name., Warning: dabo.ui.uiwx.dPemMixin  
shadows its own value -- using dabo.ui.uiwx.dPemMixin'.dPemMixin  
instead, Warning: dabo.lib.datanav.Bizobj.Bizobj's base  
dabo.biz.dBizobj is not a class, Warning: No information available  
for dabo.lib.datanav.Form.Form's base dabo.ui.dForm
While allowing introspection it finally breaks with Writing HTML  
docs: dabo.ui.uitk.dPemMixin.dPemMixin-class.html / UNEXPECTED ERROR:  
object is its own container?.
Without introspection it breaks with: Writing HTML docs: int- 
class.html / UNEXPECTED ERROR: iteration over non-sequence - i.e.  
writing a class documentation on int? Strange. Maybe some class  
inherits from int?
Up to that the output looks useful. For the records, I tried:
$ epydoc --html -o epydoc --parse-only --name dabo --url dabodev.com -- 
docformat plaintext --graph all --inheritance included dabo

If you like I can package the whole stuff and send it to you:
sphinx:  2 MB HTML, but incomplete
pydoctor: 10 MB (just HTML!)
doxygen: 64 MB HTML incl. graphics + 7,5 MB LaTeX sources incl. graphics
epydoc: 56 MB incl. graphics

[dabo-users] properties of type list

 Do you mean that you can't do:

 lst.Choices = [a, b, c]
 lst.Choices.append(d)

Yes, that's what I meant.

 but that you instead have to:

 lst = lst.Choices = [a, b, c]
 lst.Choices.append(d)
 lst.Choices = lst.Choices

I guess you meant something like?:
l = lst.Choices = [a, b, c]
l.append(d)
lst.Choices = l

At least I don't understand why you'd overwrite your list control with  
the choices list etc.

 This has struck me as kind of awkward, too. I wonder if we could  
 make it better all
 around by accepting any sequence type to Choices, but converting  
 that sequence to a
 tuple, so that if someone tries to modify it in place, they'd get an  
 exception and
 understand immediately that they have to reassign the whole sequence.

I don't see the need to make the code more complicated, if the docs  
are clear.

[dabo-users] BasePrefKey

[Henning Hraban Ramm]

Consider this snippet:

 app = dabo.dApp()
 app.BasePrefKey = 'myapp'
 app.MainFormClass = mainTest
 app.start()

At start the app warns (four times!) that there wasn't a BasePrefKey  
set and constructs one from the file's path.
That would be fine if I hadn't set BasePrefKey explicitely.

I mostly use my own Application class in this way and don't want to  
inherit it for every small tool just to set BasePrefKey in its  
afterInit.


I found in dApp.py that I should be able to set BasePrefKey in my  
MainForm, but that doesn't seem to work, at least not like this:


class mainTest(dabo.ui.dForm):
 def afterInit(self):
 if not hasattr(self.Application, 'BasePrefKey'):
 self.BasePrefKey = 'myapp'
...

If I just set self.BasePrefKey (in mainTest.afterInit), I get the  
warning only three times, but the app's BasePrefKey isn't changed  
(i.e. ignored by PreferenceManager).
The same with self.Application.BasePrefKey


Would it be possible to change dabo's handling of BasePrefKey, so that  
it's possible to set it directly on the app object?

[dabo-users] i18n / launchpad

[Henning Hraban Ramm]

Do you still use launchpad's translations 
(https://translations.launchpad.net/dabo/)?

I don't know what the problem is, but at least the German locale is  
incomplete (I'm running from SVN trunk), not only with longer  
docstrings that I didn't care to translate in launchpad yet, but also  
bits like Preferences (that string's in Launchpad since 2008-12). In  
this case the po file only has Preferences, so it doesn't apply to  
the menu entry or PreferenceDialog title.

 They are quto-generated and include all dabo classes it can find.  
 Here's the reason
 why dPref isn't found:

 class dPref(object):
   ...

 If a class doesn't ultimately inherit from dObject, it won't have  
 properties, events,
 and methods in an expected convention from which to auto-generate  
 the docs.

 If I changed it to auto-generate every class found, I think there'd

 I'm open to suggestions...

I don't know how other documentation systems (pydoctor, pydoc, Sphinx,  
Doxygen, Apydia, ...) do it. (I also didn't look how you generate docs.)
Can't you just use one of those? (Perhaps additionally?)

 The event gets raised but doesn't propagate up (by design), so the

- are dabo events usable for async programming?
- how can non-GUI objects work with events? (possibly without

 You'd need to inherit dabo.lib.eventMixin.EventMixin. It is a pretty  
 simple
 implementation.

Yes, I thought so, and that was what I tried first - but EventMixin  
knows nothing about Application or Form, and thus it's apparently not  
possible to exchange events between GUI and other objects.
Maybe I made another mistake.

 - would it make sense for the framework or my own apps to use
 something like PyDispatcher?

 For general-use event-handling, I think I'd use one of the libraries  
 built for this,
 like PyDispatcher, pubsub, or Twisted, depending on my specific  
 needs. The Dabo event
 handling stuff was designed to be general-use, but was really built  
 specifically to
 wrap wx events. If that makes any sense...

That's what I wanted to hear, thank you!

When I used Twisted with wxPython around 2004, I needed PyDispatcher  
anyway for general events, since (at last, AFAIR, at that time) both's  
events weren't usable for the kind of messaging I wanted.

[dabo-users] custom events

[Henning Hraban Ramm]

I thought I got this right...

I subclassed my events from dEvent like this:

   class OpenFile(dEvents.dEvent):
   pass

and then raise it from a button Hit handler like this:

   self.raiseEvent(events.OpenFile, filename=self.FileName.Value)

Some handler object that inherits from EventMixin and is bound in the  
Application's afterInit, binds to the event in its __init__ method  
like this:

   self.bindEvent(events.OpenFile, self.onOpenFile)

The method goes like this:

   def onOpenFile(self, evt):
   pprint.pprint(evt)

The button Hit handler gets called, and there's no error, so I guess  
the event gets sent. But it's never received.

What could be wrong? I found no documentation about dabo events, and  
from the sources and some mailing list posts this looks right to me.

Another of my own events does work, but it's bound in the App's  
afterInit, so I guess the problem ist with my non-GUI object.  
Shouldn't it be enough that it inherits from EventMixin?


BTW: The sample code in eventMixin.py is broken:

$ python eventMixin.py
EventBindings: []
EventBindings: [(class '__main__.TestEvent', function testFunc at  
0x121f6b0, False)]
Traceback (most recent call last):
   File eventMixin.py, line 360, in module
 o.raiseEvent(TestEvent)
   File eventMixin.py, line 81, in raiseEvent
 eventData=eventData, *args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'eventData'

I guess TestEvent should inherit from dEvent or at least allow  
eventData (plus *args and **kwargs).

   You need to define the appliesToClass() classmethod for your event  
 class. From dEvent.py:
...
   Look at some of the classes in dEvent.py for examples of how this  
 method works.

Since
* not all Event classes in dEvent implement appliesToClass,
* I don't care, who is raising the event
I thought I could leave that out.

Now I implement it and just return True - but the event still isn't  
received.
I also tried the issubclass test on every possible base class (sender  
and receiver) without result.

My events work within the same object, but not from e.g. a Panel to  
the App or another Panel.

Did I understand you (and the source) right that appliesToClass checks  
if the sender is allowed to raise that event?

I guess I still don't get what my (not dabo.ui descendant) object has  
to do/implement/inherit other that inheriting EventMixin und binding  
the event.


BTW, test code in eventMixin.py again:

- TestEvent must have the same signature as dEvent
- TestEvent needs a Continue property
- it's unbindEvent, not unBindEvent

Don't ask... The Zeos database access library has the same problem,
also with several other datatypes, e.g. it writes booleans and

useful format, i.e. ISO 8601. The Zeos guys couldn't accept their lib

 looked in the locale folder and found the en folder. Where should I

Just copy the en folder as jp (or the right code, look it up),  
then you'll at least be able to use an English dabo on your Japanese

Can't promise that it'll work - never tried it, but there were reports

Even if you've installed Python via MacPorts, it's probably not the

You can influence that via your path (in ~/.bashrc or ~/.profile), and  
AFAIR MacPorts says something about activation in the installation

Python 2.6 works, Python 3.x won't probably for a long time (wxPython

Re: [dabo-users] cdxml vs. coding

[Henning Hraban Ramm]

I code everything Python by hand and just don't like GUI tools for
development work – at the moment I'm working on a Delphi application
for a customer, and I hate it ;-)  I get accustomed to Delphi's GUI
tools, though, but often switch to the code view of forms, e.g. I can
use search  replace there. Unfortunately I'm not allowed to port it
to Python, I'd need half of the time and could make it much better.

For my next dabo App I might try the Designer, but since I most often
just need a simple GUI for some admin script, my hand-coded standard
interface (one tab each for Action, Settings and Log) does the job
without me learning another tool.

(BTW I *can* use vi, but only do if I must, e.g. via ssh; I prefer a
good IDE, so I'm not the evil GUI guy ;-)

You finally figured out Python's string formatting, but not completely:

Re: [dabo-users] Are many projects (commercial ) created using dabo?

Seems like you never tried django? Its batteries included admin app

But I also use a dabo app as a client app to a website, because I need  
to pull data via http request and write it to several local files.

My other dabo projects are in-house tools like our CD cover maker that  
reads the tree of a CD/DVD and creates a nice cover PDF via TeX.
At the moment I don't use any dabo apps with a database connection -  
for my needs django's admin is mostly easier.

 You are right about different encodings for different tables. As of  
 8.3 you
 can have different encodings for databases within a cluster but  
 that is far
 as it extends at the moment. Your comments about UTF-8 are wrong  
 though.
 See the link for a better explanation:
 http://www.postgresql.org/docs/8.4/interactive/multibyte.html

 I missed that he was talking about tables and not databases.

It would be enough if I could just use UTF-8 for everything.
But I didn't manage to set that up - didn't try to compile PostgreSQL  
on my own, though.
(My webserver is a vServer running Ubuntu Hardy. And I use a German  
locale.)

What about this quote from the linked page (PostgreSQL version 8.4):

An important restriction, however, is that each database's character  
set must be compatible with the database's LC_CTYPE and LC_COLLATE  
locale settings. For C or POSIX locale, any character set is allowed,  
but for other locales there is only one character set that will work  
correctly. (On Windows, however, UTF-8 encoding can be used with any  
locale.)


And on the same page for version 8.3 (that's the version on Hardy) it  
reads:

An important restriction, however, is that each database character set  
must be compatible with the server's LC_CTYPE setting. When LC_CTYPE  
is C or POSIX, any character set is allowed, but for other settings of  
LC_CTYPE there is only one character set that will work correctly.  
Since the LC_CTYPE setting is frozen by initdb, the apparent  
flexibility to use different encodings in different databases of a  
cluster is more theoretical than real, except when you select C or  
POSIX locale (thus disabling any real locale awareness). It is likely  
that these mechanisms will be revisited in future versions of  
PostgreSQL.


I understand that as your server must run under C locale. Wrongly?

 Another DnD problem:

   I'm betting that this is because the grid is not a single control,
 but a bunch of renderers and editors. IOW, you're not dropping it on
 the grid, but on a rendered cell within the grid.

I thought such; but dGrid provides processDroppedFiles, therefore it  
should work...
And I wouldn't know how to add a drop handler to every cell.
That would also contradict my idea - for me, it would be enough if the  
whole main window would accept dropped files, it doesn't matter  
*where* they are dropped.

Perhaps you saw my thread on PythonMac-SIG: I'm writing a small tool  
to detect the type of a file, esp. for my colleagues who aren't able  
or willing to call file in a shell. One should just be able to drop  
a file (or several) anywhere on the app or its icon, it gets analyzed  
with different methods, and the results get displayed in a Grid. Next  
step is to correct wrong/missing extensions and types/creators.

I'm planning to release that as an example of using dabo for a simple  
GUI app without database - or perhaps I could hold the contents of the  
magic file in a SQLite db...


   I'll try to dig into this tonight.

  OK, I did some reading on what MacOpenFile is, and it's a bound
 method of wx.App, so of course you can't simply assign it like that.
 What I'll have to do is write some code to pass the wx.App event to a
 dApp handler. This might take a few minutes, but I'll work on it now.
 In the meantime, what other wx.App event handlers are there like this
 that you know of? I might as well wrap them all.

   This is bizarre. I've found documentation that says that as of April,
 2004 (version 2.5.1.2), wxPython has 4 Mac-specific methods in its
 wx.App class:

 AppleEvents can be handled by overriding wx.App methods MacOpenFile,
 MacPrintFile, MacNewFile, and MacReopenApp.
   However, I'm running wxPython 2.8.4.0 on a Mac, and these methods
 don't exist. If I try to call them in a plain wx application (no
 Dabo), I get AttributeErrors.

   Can you point me to some definitive documetation on these methods?


Sorry, I don't know more than the wx docs told you.
I found also that it's rather complicated to handle other Apple Events  
besides that four (looks like the usual problem of interlocking  
different event loops).

But these methods aren't usually there, there's no interface/ 
implementation logic or the like in wx.
As far as I understand, they're used, if you provide them.


I'd suggest to implement those four methods in dabo's wx-uiApp and  
provide a hook in dApp - probably in a unified way, that works also  
with Windows and GTK. (If Windows or GTK provide something similar at  
all.)


Thank you for your efforts!

[dabo-users] Drag'n'drop on a dApp

[Henning Hraban Ramm]

Hi there,

I'd like to make my dabo application a drop target for files i.e.
1. DnD on the icon
2. DnD on the main window

For 1 I'd need to implement wx.App.MacOpenFile; but a dApp is no wx.App.
Where must I stuff that method, or is there a better dabo way?

For 2 I've no clue, any documentation hints?


Platform: MacOS X 10.5
Python Version: 2.5.2 on darwin
Dabo Version: Version 0.8.4; Revision 4729
UI Version: 2.8.9.1 on wxMac


BTW the Google search in the wiki searches the whole domain  
dabodev.com, i.e. finds mostly svn entries.
Additionally I got proxy errors from the wiki several times today.

   The main window is simple enough: set the window's DroppedFileHandler
 property to the object that will handle the dropped files, and write
 your code in that object's processDroppedFiles() method. That method
 will receive a list of the files that have been dropped. The dImage
 script in DaboDemo has a good example of handling dropped files.

Thank you! I'll try that.

   For the icon I'm not exactly sure what you'll need. If you create
 an .app file using py2app, files dropped on the icon will be passed as
 arguments to the main script of your app. I'm not sure what will
 happen with files dropped on an app's icon when the app is already
 running, as I've never tried it.

The argv_emulation could work ok (at the moment I get errors because  
the App object isn't initialized at start time, but I'll manage that).

For DnD on the icon I need to implement MacOpenFile within wx.App, as  
I wrote; wx's event loop (or whatever) cares for the OpenFile apple  
event.

I tried monkey patching wx.App via uiApp, but I run into the same  
problem as John: uiApp should be wx.App, but isn't, at least not while  
afterInit runs.

   You are referencing this as self.Application.uiApp, right?

   Perhaps if you posted the patch you are trying to use, we can see
 about incorporating it.


It doesn't work like I tried:

class fieeApp(dabo.dApp):

 def afterInit(self):
 self.Application.uiApp.MacOpenFile = self.MacOpenFile

 def MacOpenFile(self, filename):
 dabo.infoLog.write(u'MacOpenFile: %s' % f)



I always get an AttributeError: 'fieeApp' has no attribute 'uiApp'.

Maybe afterInit is the wrong place - but where else?

  There really is no hook for this point of the app creation code. I

   It seems to work as expected, so I've committed the change. Now if
 you grab the latest from Subversion and put your code in the app's
 afterSetup() method, it should be able to reference self.uiApp.


Thank you for your effort, but at least this method of my app doesn't  
work:

 def afterSetup(self):
 self.uiApp.MacOpenFile = self.MacOpenFile

The method itself is called, but the monkey patch doesn't seem to have  
any influence.

So Paul's suggestion of wx.GetApp() wouldn't help either.

 strange error if you try to set them outside a WX event thread.  I was
 trying to find an email on the wxPython list from Cory Percord that
 gave a more technical description of what happens, but I can't seem to
 locate it.  Instead, update a variable in the long task thread.  In
 the main UI thread call an update function that reads the variable and
 updates the progress bar.  You can do this a couple of ways.  First,
 you can use dabo.ui.callAfterInterval and a stop flag.  You can also
 use the onIdle event.  Or you can fire your own Dabo event from the
 long task thread.  They are all about the same amount of work, though
 the last one is more eloquent than the rest.

In such cases I used pyDispatcher events for the inter-thread  
communication.
I guess dEvents can do the same.
That seemed to be the cleanest approach.

Re: [dabo-users] dApp.DatabaseActivityLog and non-ASCII database content

[Henning Hraban Ramm]

Am 2008-10-02 um 18:21 schrieb Sibylle Koczian:
 Without the line app.DatabaseActivityLog = sys.stdout the  
 application works
 as expected, field content with non-ASCII characters is saved  
 normally.

 On the one hand I should have thought of this,
 because sys.stdout.write(u'äöü') raises the same  
 UnicodeEncodeError. On the
 other hand the traceback for this case definitely doesn't help. And  
 why is
 saving the record impossible, just because the _logging_ raises an  
 exception?

 I've tried to wrap sys.stdout using codecs.EncodedFile, but without  
 success. I
 don't know which input and output encoding would be right. My system  
 charset
 is UTF-8.

 Would it be possible to have DatabaseActivityLog write something
 like repr(theUnicodeObject)? Not very pretty, but for diagnostic  
 purposes
 perhaps acceptable?

You can't simply print python unicode objects to stdout.

Just change your wrapper that it works like
sys.stdout.write(u'äöü'.encode('utf-8'))

Yes, Dabo is good (even if you strive for greatness, it's still good).

But a quick look gives some more Dabos.
Most interesting:

Dabo was a roulette-style game of chance developed by the Ferengi.
(http://memory-alpha.org/en/wiki/Dabo)

Isn't that a bad omen? ;-)
And AFAIK we don't have any Dabo girls...

But (same source):
The word dabo means I will give in Latin, and Gold in Aramaic.

I knew Latin, but not Aramaic.
Another slogan: Already the Aramaeans knew that Dabo is Gold! :-D


Even more (from wikipedia):

Dabo (ダボ) is a Japanese rapper. (I knew Dabo rocks, but maybe it  
even raps?)

Dabo is a town and commune in the Moselle département, Lorraine  
région in northeastern France.

plus the already known French soccer player Ousmane Dabo and a pagoda  
names Dabotap in South Korea

Re: [dabo-users] Manually entered PK: records not saved

Am 2008-09-24 um 19:49 schrieb Paul McNett:
 No, the biz shouldn't be aware of the ui at all. If it were me, I'd  
 keep
 the PK invisible from the UI (and keep it meaningless), and just  
 define
 another field for the abbreviation field that may well be unique but
 isn't *the* pk.

Just to add another example where I use manual PKs all the time (and  
wouldn't like to change that):

Geographical lookup tables for countries or cities (PK: TLD, car/state/ 
postal code) -
I want to find D or de in my address entry, not some index that I  
would have to look up itself!

In some applications even product IDs (e.g. ISBN, EAN...) make sense  
as PKs.
E.g. in one of my web projects a publishing house uses short codes for  
its magazines; a lot of other tables relate to them; it's only that  
one lookup table that uses these codes as PK, but so we get  
understandable relations everywhere and reduce the need for joined  
queries, because the editors know their codes.

(For I use dabo only for GUIs and write database frontends with web  
frameworks, it doesn't matter for me what dabo does, but I consider it  
a drawback if you can't allow for your own PK entries.)

 Bug?

   Is this consistent with all your designs? Were there any tracebacks
 involved that would have mucked up the works? I've seen that after an
 error, but that's all the way down in the wxPython levels.

I remember a similar problem with my wxPy apps some years ago  
(without dabo) - if you close the app with the close button (not via  
some proper Quit command), it tends to hang. Unfortunately I can't  
remember the solution.
Perhaps you could hook into the close event of the main window and  
bring down the app in some safe way...

Re: [dabo-users] Standalone dabo games not running

 def _openDialog(self,evt):
 # need to receive the evt (in this case a click or Hit)
 evt.stop()
 theDialog=dabo.ui.dFileDialog(self)
 theDialog.show()
 if sys.platform == 'win32':
 myseperator = \\  # someone should post why I
 needed two slashes
 else:
 myseperator = /


You get the backslash simply this way:
   r'\' # this a raw Python string

In a normal Python string, the backslash starts a control character like
\n for newline or \t for tabulator - and \\ for backslash.

But just use os.sep instead of that myseparator distinction. Python does
that for you!
(I.e. os.sep is \ on Windows, / on Unices, : on MacOS Classic and maybe
something other on VMS...)




 Run our form or any Dabo form and type a control-d (might be something
 different for the Mac).


Every Control is a Command on the Mac, i.e. Cmd-D instead of Ctrl-D.
(Mac keyboards also have a Ctrl key, but that' seldom used at all and then
mostly for accessing additional characters.)

 After compiling my largish app with py2exe, using the same setup.py  
 that
 the AppWizard uses, I get a 34 MB or so package. Then, I use InnoSetup
 to make a setup.exe and that's only about 10 MB.

It depends on dependencies ;-)

And maybe OSX apps are generally too big due to universal binary code.

In this case I don't need any Db connection (besides sqlite for the  
preferences), but urllib and some other, and somewhere are some  
oversized dependencies. Unfortunately wxPython doesn't work if you  
leave out unused stuff (like wx.lib.calendar and wx.gizmos).
I guess I can hunt down some more unnecessary includes, but while I  
work at new features I fear the size will probably increase.

Remember, I told you about this interface to a web application:  
desktop client for a content management system (web system, but  
content for print).
It'll grow an FTP browser and become a specialized up-/download  
client with image check (PIL, oh no, more megabytes!)...

I'm playing with another script, that uses appscript to remote  
control InDesign: create pages from templates, place articles  
(written by the above mentioned app) and soon also the related  
pictures - at the moment we create about 220 pages of a city magazine  
in about 100 hours (including image processing etc.), soon we'll need  
a bit less.
When I started, we needed as much time for less than 100 pages (only  
1 regional issue, now 3).
I resent only that I wrote the web system in PHP (just exploring  
Django).

Getting completely off topic...

I guess this is because the login dialog tries to find the dabo logo
and doesn't find it, because I didn't include it in my app (why should
I?).

I couldn't find any hooks to change the login dialog. Are there any?
I don't need no logo there, and I'd like to change the labels  title also!

Re: [dabo-users] No translation file found

[Henning Hraban Ramm]

 My py2app data_files use the locales:

 localeDir = os.path.join(os.path.split(dabo.__file__)[0], 'locale')
 locales = [
 ('dabo.locale', ( os.path.join(localeDir, 'dabo.pot'), ) ),
 ('dabo.locale/de/LC_MESSAGES', (os.path.join(localeDir, 'de',
 'LC_MESSAGES', 'dabo.mo'),)),
 ('dabo.locale/en/LC_MESSAGES', (os.path.join(localeDir, 'en',
 'LC_MESSAGES', 'dabo.mo'),)),
 ]

It works with 'lib/python2.5/dabo.locale' instead of just 'dabo.locale'.
But is that how it is supposed to be?

Now I run into other errors, don't know if related:

[dabo-users] No translation file found

[Henning Hraban Ramm]

Hi there,
following the advice Paul gave to Simen I tried to get my application
running again, but had no sucess yet.

  File dabo/__init__.pyc, line 128, in module
  File dabo/dLocalize.pyc, line 53, in install
  File dabo/dLocalize.pyc, line 73, in setLanguage
  File gettext.pyc, line 469, in translation
IOError: [Errno 2] No translation file found for domain: 'dabo'

My py2app data_files use the locales:

localeDir = os.path.join(os.path.split(dabo.__file__)[0], 'locale')
locales = [
('dabo.locale', ( os.path.join(localeDir, 'dabo.pot'), ) ),
('dabo.locale/de/LC_MESSAGES', (os.path.join(localeDir, 'de',
'LC_MESSAGES', 'dabo.mo'),)),
('dabo.locale/en/LC_MESSAGES', (os.path.join(localeDir, 'en',
'LC_MESSAGES', 'dabo.mo'),)),
]

The dabo.locale directory is created in my App's Resources.
What's wrong?


Greetligs, Hraban

Re: [dabo-users] Python Version Survey

[Henning Hraban Ramm]

2007/9/6, Henning Hraban Ramm [EMAIL PROTECTED]:
 I'm using still Python 2.4.4 because it works for me - pure laziness
 to upgrade all those modules.

I know why I hesitated: There's still no pre-built MySQLdb for Python
2.5 on OS X.
Just trying to build it myself, but since you need the MySQL sources,
it's surely not for everybody.

   If you are using Python 2.5, or are planning on upgrading real soon
 now, please don't respond. I'm just trying to get an idea of the
 issues that are preventing or discouraging people from moving from
 older versions.

Re: [dabo-users] dabo as fat-client for a web service?

[Henning Hraban Ramm]

ARGL, I should spellcheck my postings...

2007/8/17, Henning Hraban Ramm [EMAIL PROTECTED]:
 I'm using a dabo client successfully with a webclient:

 We've an editorial content management system as a web app. The client
 pulls the articles, formats them as InDesign tagged text (event
 calendar data also as XML) and saves them to a local dir tree (that's
 why we can't use the web app for export).
 The client fills the normal login form, grabs the session handle and
 then calls a backend page, that provides the data as JSON. Not
 only the articles, but also metadata like issues, topics etc.

 The layers:
 - GUI is handcoded; I use mostly adapted classes that know how to
 handle our special data. I guess there's already too much processing
 logic in it (path handling etc.)
 - BIZ (workflow, export what to where) is mostly in the main app.
 - BACKEND is a webclient class that knows how to handle our special
 connection, how to get data and how to convert JSON to pythonic dicts
 and lists.
 - EXPORTERS (called by the main app) format the pythonic data into the
 stuff we need (InDesign is very picky - claims to understand unicode
 data, but takes only UTF-16 without BOM and with Mac XOR Win
 lineendings. Lots of errors in the tags documentation. etc.)

 So I didn't subclass dBizobj because I didn't see how it would fit my needs.
 And I'm not really used to 3T programming ;-)


 Greetlings, Hraban

Re: [dabo-users] dabo as fat-client for a web service?

[Henning Hraban Ramm]

 So... Dabo is pure GUI. Do you use the dApp object? Do you subclass and
 instantiate Dabo's UI classes or just instantiate and use?

I use subclasses of dApp, dSecurityManager, and several UI classes,
and only a few original UI classes (I often sublass even for single
use, because I find it more concise).

Thanks for your great work!

BTW: I'm running daily SVN updates in a cronjob, otherwise I'd have to
keep track on too much projects.

Greetlings, Hraban
