Application losing focus when dialog is destroyed

wxPython Users
1

My application creates a pyprogress dialog and then starts a
processing function in a thread that updates the variables that are
passed to the pyprogress dialog through it's UpdatePulse function

        self.func.labelup = ""
        dlg = pyprog.PyProgress(None, -1, "Please wait.",
                            "Doing work.",
                            style = wx.PD_APP_MODAL|
wx.PD_ELAPSED_TIME)
        threading.Thread(target=self.func.DoWork, args=
(filelist,)).start()
        while 1:
            dlg.UpdatePulse(self.func.labelup)
            wx.MilliSleep(50)
            if self.func.dwbool == False:
                break
        dlg.Destroy()

this works fine, but when the dialog is destroyed, my application
loses focus (the next topmost window is brought to the front)

I'm having trouble finding out the cause of this, does anyone have any
ideas?

Let me know if you need more info

Its because the PyProgress parent is None.

I've tried putting a few different targets as the parent to no avail.
Also it's None in the demo which doesn't exhibit the same behavior..

Does the demo have multiple windows though? I don't think it
does...what you probably need to do is use pubsub to send a message to
the frame that spawned the progress dialog. When the frame received
the message, you can just call its Raise() method.

In terms of the way the demo is using the progress dialog my app is
very similar, my app only has 1 frame as well...and that frame is the
one calling the dialog and destroying it

I believe I've figured it out, the way I was destroying the dialog was
preventing the dialog from re-enabling the main window, calling
pyprogress's OnCancel first fixed everything (as far as i can tell).

typical bonehead mistake. should've done more investigating before
asking. thanks for the suggestions..

Just out of curiosity, how does the group here handle version control and different versions of your software? What do you recommend? I'm currently not using an IDE at all (I find it helps me learn the language better if I don't use an IDE), but I am realizing that it might help to have some form of version control. I'm on Mac OS X 10.5, so I am also interested in what works for you if you are on the Mac. But other solutions (that might also work on the Mac) would be nice to learn about.

Thanks,

Stuart

Our group (~15 developers at multiple sites, the majority with Macs) uses SVN. It’s not ideal if you need to deal with branches that may need to be merged, but apparently a big improvement over CVS. I have no complaints except for the branch handling, and if you’re working alone or with a small group, it’ll probably be just fine. (And apparently the newest release is much better with branches.)

Hello,

Just out of curiosity, how does the group here handle version control
and different versions of your software? What do you recommend? I'm

OSX 10.5 comes with cvs and svn pre-installed. Both are accessible
from the command line and relatively easy to use. So far out of the
distributed scm systems mercurial seems the most user friendly and
intuitive to use in my experience.

Editra (included with wxpython) also has a Projects plugin (separate
download) that provides a simple gui interface to many different scm
systems.
