gui application on cross platform


Hi,

I am using delphi to develop gui application, and wish to make a shift
to python. here are some of my question/concern...

1. is python develop gui application a cross platform? just like java
swing?
2. delphi makes things easy for me like coding for a specific event on
a specific component, could it be the same for python?
3. are there cool library of component like in delphi available for
python that will make database application more usesable?
4. where do I start the learning curve? I did some research and I
don't know which one to take among wxwdiget, pygtk, and etc.

Thanks
james

Yes. Qt, wxwidgets and pygtk run on Linux and Windows, don't know
about Macs.

Not in the Delphi way but glade/gazpacho are good GUI designer for
gtk.
I have no experience with qtdesigner or the wx equivalent app.

python has dbapi, all DBs look the same, python can also use ORM like
SQLObjects and SQLALchemy

I tried wxwidgets and pygtk, then I decided to use pygtk but it
could be I'll change my mind in the future.

Thanks sc,

What do you mean when you say .."all DBs look the same"

what is the difference between pygtk and wxwidgets?

Explore the Python wiki, specially  
<http://wiki.python.org/moin/GuiProgramming> and ChoosingGuiToolkits.
Here you have and "Intelligent GUI chooser"  
<http://www.awaretek.com/toolkits.html>
Search previous posts on this group too as this is a recurring topic.

I'm also going down this path, and have decided on python + wxWidgets +
boa as the RAD tool.  From the tutorial, it seems pretty easy to use,
except for some minor annoyances on both windows and linux platforms.

Under windows, for some inexplicable reason the "dialogs" tab is not
present, while under linux, I can't seem to drag components around the
frame after placement.

Cheers,

May I suggest you take a close look at Dabo (www.dabodev.com).  Dabo was
designed from the ground up to do exact what you are asking for.  Take a
look at the Dabo screencast
(http://leafe.com/screencasts/dataenvironment1.html)
which will provide an easy review of most of what Dabo can do.

        wxPython is probably the best cross-platform GUI toolkit available  
for Python. That's why we chose it for our primary UI toolkit for Dabo.

        Not in Python per se, but I know exactly what you mean.

        I come from the Visual FoxPro world, which is very similar to  
Delphi. I stumbled upon Python, and quickly discovered that it was  
far and away the best language I've programmed in in over 3 decades  
of coding. Yet it lacked anything like the power of GUI development  
that tools such as Delphi or Visual FoxPro offered. So along with my  
partner Paul McNett, we set out to create such a tool, and that is Dabo.

        One word: Dabo. We do database apps.

        Check out our collection of screencasts to see what Dabo can do for  
you (http://dabodev.com/documentation). Post messages to the dabo-
users list to get answers to any questions you might have (sign up at  
http://leafe.com/mailman/listinfo/dabo-users).

        There are a ton of web frameworks out there. But for Python, there  
is only one desktop app framework: Dabo.

My first programming language was Delphi, and (after having to work
several years with java), I had to restart programming, but only for
my little home purpose (educatives for my children).
I dive into python and I love it !
In a couple of days, I did a little program to manage and launch the
roms of some console emulators with screenshots.
I develop it and use it on my laptop on Gentoo linux, and run it on
the windows desktop of my children. NO line has to be modified between
the os, it is fantastic !
I use simple python for console text apps, wxPython for management
graphical applications, and pygame for some little full of sprites
games :-)

pygtk uses GTK
wxwidget use a different gui toolkit on different platform. It is
probably the best crossplatform GUI.
I used pyGTK simply becouse my GUI apps runs only on gnome.
