How to create a non-interactive message-to-user in a window ?

Barak_Ron · February 1, 2009, 9:26am

Hi,

Maybe one of you has an idea for the following ?

My script needs to ungzip a tar archive.
I want to give user feedback that this operation is being performed, without requiring user interaction (so, modal dialogs are out).

The best I could manage was using the following:

def un_tgz(app,tgz_save_states_paths):
“”"
“”"
for path in tgz_save_states_paths:
cwd = os.path.dirname(path)
# Temporarily change directory to the directory of the tgz file
# (save $cwd in cwd) so the untarring will be done in the
# same directory where the tgz file resides.
if (path.rfind(".tgz") != -1):
tgz_dir = os.path.dirname(path)
tgz_name = os.path.basename(path)
(tgz_name_without_extension, extension) = os.path.splitext(tgz_name)
save_state_name = os.path.join(tgz_dir,tgz_name_without_extension)

        # If save_state sub-dir already exists in same directory as tgz_dir,
        # do not unzip tgz_name, but give approperiate message.
        if glob.glob(save_state_name):
            msg = "Directory %s already exists in %s. %s will not be untarred!" % (tgz_name_without_extension,
                    tgz_dir, tgz_name)
            info_message_without_interaction(msg)
            print line()+". "+msg
        else:
            msg = "Untarring %s  into  %s." % (tgz_name,tgz_dir)
            info_message_without_interaction(msg)
            print line()+". "+msg
            os.chdir(tgz_dir)
            tar = tarfile.open(path)
            tar.extractall()
            tar.close()
            os.chdir(cwd)

def info_message_without_interaction(msg):
“”"
“”"
average_char_width = 7
frame = wx.Frame(parent=None, title=msg, size=(average_char_width * len(msg),0))
panel = wx.Panel(frame)
sizer = wx.BoxSizer(wx.VERTICAL)
frame.Show()

Which put on the screen a frame with only a title, while the untarring is performed.

However, I did not manage to make the frame include a widget that could display text (e.g., StaticText), so the message to the user will be not just in the frame heading.

Any ideas ?

Thanks,
Ron.

Personally, I prefer my users have Snarl installed if they’re on Windows, or Growl if on mac – I have no linux folk at the moment so don’t know about the equivalents. But in the case that one doesn’t have either of those, I fall back to Andrea Gavana’s ToasterBox (http://xoomer.alice.it/infinity77/main/ToasterBox.html), doing basically the below for what its worth. The Growl and snarl libraries I got off the respective notifiers websites.

def send(message, title=None):
import subprocess
messageShown = False
if sys.platform == “win32”:
try:
import snarl
snarl.snShowMessage(title and str(title) or “My Application”, str(message), timeout=5)
messageShown = True
except:
logging.exception("(Non-Fatal Error) Snarl not present to send notification to.")
else:
try:
import Growl
gn = Growl.GrowlNotifier(applicationName=“My Application”, notifications=[“Falcon Message”], defaultNotifications=[“My Application’s Message”])
gn.notify(“My Application’s Message”, title and title or “My Applicationl”, message)
messageShown = True
except:
logging.exception("(Non-Fatal Error) Growl not present to send notification to.")

if not messageShown:
    import ToasterBox as TB
    import wx
    app = wx.GetApp()
    if app:
        top = app.GetTopWindow()
        if top:
            tb = TB.ToasterBox(wx.GetApp().GetTopWindow(), TB.TB_SIMPLE, 0, TB.TB_ONCLICK)
            tb.SetPopupSize((210,130))
            tb.SetPopupPauseTime(4000)
            tb.SetPopupScrollSpeed(1)
            tb.SetPopupText(message)

            ScreenWidth = wx.SystemSettings.GetMetric(wx.SYS_SCREEN_X)
            ScreenDepth = wx.SystemSettings.GetMetric(wx.SYS_SCREEN_Y)               
           
            left = ScreenWidth - 210
            top = ScreenDepth - 130

            tb.SetPopupTextFont(wx.Font(12, wx.SWISS, wx.NORMAL, wx.NORMAL, False))
           
            tb.SetPopupPosition((left, top))
            tb.Play()

Hi Mr. Hansen,

Thanks for the tip on ToasterBox. It is an excellent widget, and is well suited to my needs.

BTW, I’m unable to set the foreground colour (using SetPopupTextColor) to anything but the default wx.BLACK.
This happens both in ToasterBoxDemo.py and in my own application.
Is that a known bug (didn’t really find one while Googling) or is that my environment ?

Bye,

Ron.

P.S.: I’m running on Windows XP. Python 2.5.2. wx-2.8-msw-unicode.

So what are the install-time pre-requisites for Snarl / Growl?

The thing I like about TB is that it's implemented wholly in *my*
application.

I like the /idea/ of a central notification manager, but I don't like
having to make my user install something extra.

I already have to ask them to install Python, wxPython and Pyro.

Hi R,

I downloaded the ToasterBox zip from http://xoomer.alice.it/infinity77/main/GUI2Exe.html.

If I want to update my 2.5.2 Python with an updated ToasterBox, where should I point my SVN client ?

Looking at http://www.wxpython.org/download.php, I don’t see references to my Python version (I never used SVN, so I may know the correct questions to ask).

Bye,

Ron.

Andrea uses the wxPython SVN repository.

I use the cygwin command-line SVN client, so to get AGW (which contains
ToasterBox), I just do

svn co http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW

Let's say that you end up with c:\src\AGW checked out.
Then I just put c:\src\AGW on my PYTHONPATH and when I import
agw.toasterbox I get the one from SVN.
When AGW starts shipping with wxPython (probably at version 2.9 (being a
dev. release)), it'll probably just come for free with wxPython (likely
as wx.agw.toasterbox or something like that).

I just looked and it does indeed look like my patch is in SVN.

Enjoy,

Hi R,

It seems I have problems just connecting to the SVN (as I said, I never used SVN before).
I’m trying to connect from a cygwin and I get:

$ svn co http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW
svn: OPTIONS of ‘http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW’: could not connect to server (http://svn.wxwidgets.org)

I couldn’t find a verbose option on SVN, so all I could think of was to strace the command (below), but that didn’t help much either, it terms of clues.

Trying to follow http://ist.berkeley.edu/as-ag/tools/howto/cygwin.html, and http://instantbadger.blogspot.com/2006/09/svn-over-ssh-svnssh-on-windows-via.html didn’t help much either:

Warning: Permanently added ‘svn.wxwidgets.org,72.9.158.153’ (RSA) to the list of known hosts.

Could you guess what is wrong ?

Hi R,

If I want to update my 2.5.2 Python with an updated ToasterBox, where

Andrea uses the wxPython SVN repository.

I use the cygwin command-line SVN client, so to get AGW (which contains ToasterBox), I just do

svn co http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW

Let’s say that you end up with c:\src\AGW checked out.
Then I just put c:\src\AGW on my PYTHONPATH and when I import agw.toasterbox I get the one from SVN.
When AGW starts shipping with wxPython (probably at version 2.9 (being a dev. release)), it’ll probably just come for free with wxPython (likely as wx.agw.toasterbox or something like that).

I just looked and it does indeed look like my patch is in SVN.

Enjoy,

It seems I have problems just connecting to the SVN (as I said, I never used
SVN before).
I'm trying to connect from a cygwin and I get:

$ svn co http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW
svn: OPTIONS of 'http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW’:
could not connect to server (http://svn.wxwidgets.org)

I couldn't find a verbose option on SVN, so all I could think of was to
strace the command (below), but that didn't help much either, it terms of
clues.

What version of svn? Is it a cygwin build or a windows build? Maybe try installing a regular windows version and just svn'n from a regular command prompt: the syntax is identical.

Other then that: it works fine for me. Do you have some sort of HTTP proxy that sits on your internet? It could be interfering: svn is using webdav and some proxies and such don't pass those HTTP commands around right, I've heard.

You can't use svn+ssh because that requires you to have an actual ssh account on the host box. The command you entered -is- the right one and there's nothing else you enter to tell svn to do anything else differently, the problem has to be lower level then it.

So what are the install-time pre-requisites for Snarl / Growl?

The thing I like about TB is that it's implemented wholly in *my*
application.

I like the /idea/ of a central notification manager, but I don't like
having to make my user install something extra.

I already have to ask them to install Python, wxPython and Pyro.

Both Snarl and Growl come with simple installers.

That's why I do have ToasterBox as a fallback. Personally, on the mac? TONS of people have Growl. Its really quite common, though not universal. I find it very annoying -- very -- when applications do their own notifications if those notifications aren't /just right/ (and I define /just right/ as "happening to behave exactly as Growl's preferences are currently set to behave" :)) For example, I positively loathe bottom-up notifications. The proliferation of them annoyed me into quitting using an app once But to each his own, which is exactly why I like supporting Snarl/Growl where its available: if someone has installed it it means I'll be able to talk to them the way that they have determined they like to be talked to.

Snarl isn't as wide-spread on the Windows world, but more and more apps supporting it will help As Snarl was recently released as a Simplified BSD, I'm probably going to bundle it along as an optional install -- but I'm using an installer and it looks like you're not. I can't ask my users to install Python, so I just give them a single installer with python + wxpython + all kinds of crap

Hi,

Maybe one of you has an idea for the following ?

My script needs to ungzip a tar archive.
I want to give user feedback that this operation is being performed, without requiring user interaction (so, modal dialogs are out).

wx.BusyInfo is something that will probably work well in this case. You also might want to look at wx.ProgressDialog.

Hi S,
I managed to get my SVN (in cygwin) to work.
The new (SVN's) toasterbox.py solves the foreground colour problem (SetPopupTextColor).
However, the toasterboxes still appear in the same spot (one above the other) on the screen, so SetPopupPositionByInt still does not seem to work.
Below is the script (modified per Andrea's suggestions), that demonstrates the SetPopupPositionByInt problem (on my machine, at least).
Bye,
Ron.

Subject: Re: [wxpython-users] Re: ToasterBox's SetPopupTextColor dosen't work ?

It seems I have problems just connecting to the SVN (as I said, I
never used SVN before).
I'm trying to connect from a cygwin and I get:

$ svn co http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW
svn: OPTIONS of 'http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW’:
could not connect to server (http://svn.wxwidgets.org)

I couldn't find a verbose option on SVN, so all I could think of was
to strace the command (below), but that didn't help much either, it
terms of clues.

What version of svn? Is it a cygwin build or a windows build? Maybe try installing a regular windows version and just svn'n from a regular command prompt: the syntax is identical.

Other then that: it works fine for me. Do you have some sort of HTTP proxy that sits on your internet? It could be interfering: svn is using webdav and some proxies and such don't pass those HTTP commands around right, I've heard.

You can't use svn+ssh because that requires you to have an actual ssh account on the host box. The command you entered -is- the right one and there's nothing else you enter to tell svn to do anything else differently, the problem has to be lower level then it.

Hi Ron,

Hi S,
I managed to get my SVN (in cygwin) to work.
The new (SVN's) toasterbox.py solves the foreground colour problem (SetPopupTextColor).
However, the toasterboxes still appear in the same spot (one above the other) on the screen, so SetPopupPositionByInt still does not seem to work.
Below is the script (modified per Andrea's suggestions), that demonstrates the SetPopupPositionByInt problem (on my machine, at least).

As I told you yesterday, ToasterBox is *meant* to work in that way:
once the first ToasterBox is displayed (in whatever position you
choose at the beginning), all the subsequent ToasterBox windows will
pop up one on top of the other. So, if the first position is top-left
of the screen, all the others will be top left of the screen. The only
thing you control is the very first ToasterBox position (either in
absolute pixels coordinates using SetPopupPosition or by screen
location using SetPopupPositionByInt).

Andrea.

Hi Robin,

wx.ProgressDialog does look interesting, but - after reading Manning’s (wxPython in Action) “9.1.5 How can I display progress?” and www.wxpython.org/docs/api/wx.ProgressDialog-class.html, I cannot figure how I can use it in my application.
What I do is going through a list of “tgz” files, and for each checking if an un-tar-un-gzip directory already exists, and if it does not, I do a tar.extractall.

Since tar.extractall is only one command, I don’t understand how to incorporate it with ProgressDialog: how would ProgressDialog know of the progress the tar.extractall is having ?

Below is the un_tgz function I use to do the untarring.

Hi,

Maybe one of you has an idea for the following ?

My script needs to ungzip a tar archive.
I want to give user feedback that this operation is being performed,
without requiring user interaction (so, modal dialogs are out).

wx.BusyInfo is something that will probably work well in this case. You also might want to look at wx.ProgressDialog.

like this:

dlg.Pulse()

# Run in a separate thread
thread = TARThread(self)

while thread.isAlive():
wx.MilliSleep(300)
dlg.Pulse()

dlg.Destroy()
wx.SafeYield()

class TarThread(Thread):
""" Worker thread class to attempt untar of files."""

    def __init__(self, notifyWindow):

        # This starts the thread running on creation, but you could

        self.start()

Hi Andrea,
Thanks for your suggestion.
What you outlined below seems a bit too intricate just to give the user more elaborate feedback than using your ToasterBox.
I'll probably use your script below as a basis for another part of my program, where threads are essential.
Thanks and Bye,

I am happy you found it useful. Anyway, remember that if you are
un-tarring very big files, your GUI will become unresponsive until
tar.extractall() has finished, blocking all user interaction with your
interface. You may also take a look at this Wiki page:

Rather than using tar.extractall, you could iterate over the result of
tar.getmembers(), calling tar.extract(member) for each one. Here's an
example (untested):

def default_progress_callback(stage, step, total):
print "%s (Step %d of %d)" % (stage, step, total)

def extract_with_progress(tarfile,
progress_callback=default_progress_callback):
    members = tarfile.getmembers()
    for i, member in enumerate(members):
        progress_callback('Extracting...', i + 1, len(members))
        tarfile.extract(member)

In the attachment to
http://article.gmane.org/gmane.comp.python.wxpython/64836 there is a
'ProgressWindow' which is a wrapper round wx.ProgressDialog and can be
passed as a progress_callback function to provide the graphical
feedback, rather than just printing.

Hope that helps,

Simon

Hi Andrea,

Ah, I guess I was too tired, as I missed that ;-(

How would you go about solving the problem of having more messages than screen height ?
In my application, I untar several files, and each file creates it’s own ToasterBox as feedback.
After several files are processed, the ToasterBoxes are printed above the top edge of the screen.

Bye,
Ron.
