Re: Best GUI for Python
On 2015-04-26, Cecil Westerhof ce...@decebal.nl wrote: I want to use a GUI for Python. When searching I found (beside some others) Tkinter and wxPython. From what I found it looks like Tkinter is slightly better. What would be the pros/cons of these two? Would there be a compelling reason to use another GUI? For cross-platform work, I think it comes down to wx or Qt. I've used them on Windows, Mac and Linux. Qt has the more polished and consistent API, and is more popular with the big scientific Python distros. wx has the most liberal license, and I think having to deal with only one Python binding is somewhat an advantage. I've gone back and forth between them, and could probably live with either one. Gtk is also worth looking at if you only care about Linux.

Has this changed? In Python? I've been using wxpython for 6 or 7 years, and it's always used callbacks in Python. The API is not as polished or extensive as Qt, but it's still very capable. I think it's easier to write custom widgets in wxpython because there are so many examples to follow. Recently I decided to use PyQt for a project that was required to run on win32 and OS X, and for some reason my layout, wich was fine under win32, was screwed up on OS X.

I use wxPython for commercial work because it had the more liberal license at the time I started using it (PySide was not available at that time). As far as features and maturity go, I think both wx and Qt are fairly equal. Qt has become more popular for scientific work. PyGtk and Glade are another option, particularly on Linux, though I think wx or Qt still have better compatibility with Win32 or OS X. For OS X only, PyObjC and XCode are an option.

I was hoping it would not have one pysqlite2 limitation: if you have an empty database, cursor.description always returns None, even if you have pragma empty_result_callbacks=1 (pysqlite 1.x doesn't have the problem). But apsw also requires data to be avaliable before you can get column descriptions. However, the tracing stuff and the various hooks you can set look really interesting.

For me, the code completion feature. Also, modern anti-aliased font rendering under Linux doesn't hurt. Emacs python-mode is still ahead on code formatting. For example, the way you can line up code by hitting tab once anywhere on the line. And I miss emacs things like M-^ (delete-indentation; joins the line to the previous line and removes whitespace). Eclipse has an emacs keybinding mode, but it's not very comprehensive. I'm not ready to switch, but I played around enough to know I could get fairly comfortable if I wanted to. I exaggerated memory usage a bit. Eclipse only uses about twice as much RAM as XEmacs on my Linux box. Still, I probably wouldn't find it as usable if this wasn't an AMD64 3200 with 1G RAM.

However when you start of to program and want to do some rearranging to the gui, wxglade overwrites your file and you've got to put your own code back in. How about generating XRC files instead of Python? I admit I've never tried it with wxGlade, so I don't know how well it works, but with the original Glade one only uses XML, you can't generate Python at all.

Don't forget Swing and SWT via Jython. Of course that brings with it all the joys and sorrows of Java. GTK on the Mac (OS X) requires installing and running an X server (an X server is included on Apple's OS X install discs, but not installed by default; it can also be downloaded for free from Apple). This may be enough of an annoyance to turn some users off. I've had success with using GTK on win32, and it's very standard on Linux systems. I'm not sure what the status of QT on OS X is. Tkinter still seems viable for things that don't require a lot of complex controls. Also, it has a very powerful canvas widget. However, it won't look very good on unix systems (no anti-aliasing, for one thing). If you don't need a lot of complex controls, you might consider the embedded webserver + browser route using CherryPy or Twisted.web + Nevow. wxPython seems to have the best cross-platform support among CPython toolkits, but it never seemed very Pythonic to me. There's a higher-level package called wax that aims to remedy that. Dave Cook -- http://mail.python.org/mailman/listinfo/python-list
