Subject: [Idle-dev] An unusual use for single process mode
Message-ID: <502567AB.6020008@submitnet.net>

I note that several here are contemplating dropping single-process mode.
I use idle in single-process mode to interactively develop Tkinter code.
The value I find is in how I can try Tkinter commands one-at-a-time and 
see what happens without building and running a testbed.
Try it, you might like it:

         $ python -m idlelib.idle -n &

In the idle window:

         >>> import Tix
         >>> p = Tix.Entry(show=u'\xbf')
         >>> p.master.title('Password')
         >>> p.pack()
         >>> p.get()
<enter text>
         >>> p.get()

I agree that interactive GUI development can be useful. Allowing Tk to 
work with a subprocess has been fixed in 3.3. See 
http://bugs.python.org/issue989712
Unfortunately these changes were not backported to 3.2 and 2.7, but they 
can be added quite simply.

Also, the IdleX extensions project provides the EventLoop.py extension 
which allows for interactive GUI development with Tk, GTK, Qt, WX, and 
others. See http://idlex.sourceforge.net/extensions.html

Subject: [Idle-dev] Dragging Window Not Smooth
Message-ID: <CA+0b8+SnFXd6J8np-fv9Cn04W6QBcGukJpC1j_482gcxMnGN3A@mail.gmail.com>

While moving my IDLE window I noticed that the movement is really laggy ?
why is this?  I tried it at work and home, so it clearly isn't an isolated
case.

Any suggestions?

Regards,
oliver

What version of IDLE are you using? What OS are you using? If Linux, are 
you using a compositing window manager?

Are you dragging the window to a different location on the desktop, 
resizing the window, or scrolling the text contents with the vertical 
scroll bar?

I hadn't noticed it before, but I started Idle 3.2 on Windows 7 and
observed it does not move smoothly. Other editors (e.g. I tried GVIM
and Notepad) move smoothly when dragged by their title bar. I'd guess
they're hitting at least 30fps, probably quite a bit better. Idle has
quite jerky movement. I'd guess maybe 10fps. So far as I can tell,
this affects all Idle windows, but *only* while the shell window is
open. If you have open only a document window, it's smooth and snappy
like any other editor.

Confirmed with 3.3.0b1, Win7, 64 bit, fast, year-old machine and 
graphics, including change in edit window behavior with and without 
shell window. I have not seen anything like this with any other program. 
If I move window quickly, it seems to jump about 1/4 inch at a time.

I'm not seeing this problem with Arch Linux under Gnome 3. Try running 
IDLE without a subprocess to see if the dragging behavior still occurs.

The shell window, (PyShell instance) polls the subprocess every 50 ms 
which may be the source of the delay. Search for "self.pollinterval" in 
PyShell.py to adjust this value. My guess is that higher values will 
cause the dragging to be more responsive.

The Tk eventloop may be stalling during this poll which may then be 
preventing the movement of the window. I don't know enough of how Tk and 
Win7 interact for window placement to be sure, however.
