As far as I can tell the Designer saves cdxml files which appear to
contain a mixture of xml and Python - the Python code for any event
routines that you code. I presume that the Dabo framework can be
given cdxml files and it will fire them up showing the gui.
The code editor lets me write code for event methods and define my
own methods, but I can only see one method at a time (shades of VB
4.0) at a time and I can't write Python classes or even import
statements to get at code in other python modules.
I am obviously missing a key concept.
Probably the only one that you're missing is that the Designer
is not the end of the line as far as Dabo visual tools are concerned.
Future plans include a full IDE that will include project management,
a regular editor for editing any file you like, database connection
management, etc. What we've done is create the individual tools
first, with the goal of eventually tying them all together. Right now
we have the visual class designer, the connection editor, an editor
for Python code, and a few other tools. While I'm cleaning up the
last few bugs in the class designer, I'm sketching out ideas for the
IDE, both on paper and in my head. I'm looking at several other IDEs
out there to get a sort of "like/don't like" list, so that when the
time comes to actually start coding it, I'll have a good idea of what
I want it to look like and how I'd like it to work.
To answer some of your specific questions:
I presume that the Dabo framework can be given cdxml files and it

Yes, Dabo can create a live form from a .cdxml file. If you
already have an app running, you can just call: dabo.ui.createForm("/
path/to/myfile.cdxml"), and that will create the form from the saved
design. You can also set the .cdxml file as the MainFormClass of your
app, and Dabo will correctly handle that. Or you can choose "Save
Runnable App" from the menu, and that will create a small .py file
that you can run to that will run your design for you.
The code editor lets me write code for event methods and define my
own methods, but I can only see one method at a time (shades of VB

That's the way that the Designer works for now; when we
integrate it into the IDE, that will probably change.
and I can't write Python classes or even import statements to get
at code in other python modules.
To write Python classes, you probably want to run Editor.py,
which gives you a full Python editor. There is a glitch that I have
not been able to get an explanation from the Python powers-that-be as
far as the placement of 'import' statements: if they are written
*outside* of the method, they compile and run just fine, but when you
use descriptors to run them from a class (as is done when you run
a .cdxml file), they don't work, even though the compiled method is
identical. So for now, add your import statments *inside* your
method; e.g.:
def onHit(self, evt):
import time
self.Caption = time.ctime()
Hope that helps,
