  • Remove padding in wxPython's wxWizard

    - by mridang
    Hi Guys, I'm using wxPython to create a wizard using the wxWizard control. I'm trying to a draw a colored rectangle but when I run the app, there seems to be a about a 10px padding on each side of the rectangle. This goes for all other controls too. I have to offset them a bit so that they appear exactly where I want them to. Is there any way I could remove this padding? Here's the source of my base Wizard page. class SimplePage(wx.wizard.PyWizardPage): """ Simple wizard page with unlimited rows of text. """ def __init__(self, parent, title): wx.wizard.PyWizardPage.__init__(self, parent) self.next = self.prev = None #self.sizer = wx.BoxSizer(wx.VERTICAL) title = wx.StaticText(self, -1, title) title.SetFont(wx.Font(18, wx.SWISS, wx.NORMAL, wx.BOLD)) #self.sizer.AddWindow(title, 0, wx.ALIGN_LEFT|wx.ALL, padding) #self.sizer.AddWindow(wx.StaticLine(self, -1), 0, wx.EXPAND|wx.ALL, padding) # self.SetSizer(self.sizer) self.Bind(wx.EVT_PAINT, self.OnPaint) def OnPaint(self, evt): """set up the device context (DC) for painting""" self.dc = wx.PaintDC(self) self.dc.BeginDrawing() self.dc.SetPen(wx.Pen("grey",style=wx.TRANSPARENT)) self.dc.SetBrush(wx.Brush("grey", wx.SOLID)) # set x, y, w, h for rectangle self.dc.DrawRectangle(0,0,500, 500) self.dc.EndDrawing() del self.dc def SetNext(self, next): self.next = next def SetPrev(self, prev): self.prev = prev def GetNext(self): return self.next def GetPrev(self): return self.prev def Activated(self, evt): """ Executed when page is being activated. """ return def Blocked(self, evt): """ Executed when page is about to be switched. Switching can be blocked by returning True.

  • Explicit disable MySQL query cache in some parts of program

    - by jack
    In a Django project, some cronjob programs are mainly used for administrative or analysis purposes, e.g. generating site usage stats, rotating user activities log, etc. We probably do not hope MySQL to cache queries in those programs to save memory usage and improve query cache efficiency. Is it possible to turn off MySQL query cache explicitly in those programs while keep it enabled for other parts including all views.py?

  • SQLAlchemy - select for update example

    - by Mark
    I'm looking for a complete example of using select for update in SQLAlchemy, but haven't found one googling. I need to lock a single row and update a column, the following code doesn't work (blocks forever): s = table.select(table.c.user=="test",for_update=True) u = table.update().where(table.c.user=="test") u.execute(email="foo") Do I need a commit? How do I do that? As far as I know you need to: begin transaction select ... for update update commit

  • Technique to remove common words(and their plural versions) from a string

    - by Jake M
    I am attempting to find tags(keywords) for a recipe by parsing a long string of text. The text contains the recipe ingredients, directions and a short blurb. What do you think would be the most efficient way to remove common words from the tag list? By common words, I mean words like: 'the', 'at', 'there', 'their' etc. I have 2 methodologies I can use, which do you think is more efficient in terms of speed and do you know of a more efficient way I could do this? Methodology 1: - Determine the number of times each word occurs(using the library Collections) - Have a list of common words and remove all 'Common Words' from the Collection object by attempting to delete that key from the Collection object if it exists. - Therefore the speed will be determined by the length of the variable delims import collections from Counter delim = ['there','there\'s','theres','they','they\'re'] # the above will end up being a really long list! word_freq = Counter(recipe_str.lower().split()) for delim in set(delims): del word_freq[delim] return freq.most_common() Methodology 2: - For common words that can be plural, look at each word in the recipe string, and check if it partially contains the non-plural version of a common word. Eg; For the string "There's a test" check each word to see if it contains "there" and delete it if it does. delim = ['this','at','them'] # words that cant be plural partial_delim = ['there','they',] # words that could occur in many forms word_freq = Counter(recipe_str.lower().split()) for delim in set(delims): del word_freq[delim] # really slow for delim in set(partial_delims): for word in word_freq: if word.find(delim) != -1: del word_freq[delim] return freq.most_common()

  • Django does not load internal .css files

    I have created a Django project in local which runs without any kind of problem.

  • strange chi-square result using scikit_learn with feature matrix

  • I'm making a simulated tv

    I need to make a tv that shows the user the channel and the volume, and shows whether or not the television is on.

  • Can PyAMF support service deployment by way of the filesystem?

    - by Chris R
    I'm evaluating PyAMF to replace our current PHP (ugh) AMF services framework, and I'm unable to find the one crucial piece of information that would allow me to provide a compelling use case for changing over: Right now, new PHP AMF services are deployed simply by putting the .php files in the filesystem; the next time they're accessed, the new service is in play. Removal of a service is as simple as deleting the .php file that provided it, and updating it is correspondingly simple. I need that same ease-of-deployment from PyAMF. If we have to rewrite our installers to deploy these services, it'll be a nonstarter. So, what I need to know is, can PyAMF support new service discovery by way of the filesystem, can it support service upgrading and removal by way of same, and if so, what is the best way to set it up to do this? I'm open to any of the various server options; I can easily have cherrypy, django, whatever installed and running on its own, and even -- with a bit more sturm nd drang -- have mod_python or mod_wsgi made available.

  • How to model a social news feed on Google App Engine

    - by PEZ
    We want to implement a "News feed" where a user can see messages broadcasted by her friends, sorted with newest message first. But the feed should reflect changes in her friends list. (If she adds new friends, messages from those should be included in the feed, and if she removes friends their messages should not be included.) If we use the pubsub-test example and attach a recipient list to each message this means a lot of manipulation of the message recipients lists when users connect and disconnect friends. We first modeled publish-subscribe "fan out" using conventional RDBMS thinking. It seemed to work at first, but then, since the IN operator works the way it does, we quickly realized we couldn't continue on that path. We found Brett Slatkin's presentation from last years Google I/O and we have now watched it a few times but it isn't clear to us how to do it with "dynamic" recipient lists. What we need are some hints on how to "think" when modeling this.

  • Django: Admin with multiple sites & languages

    - by lazerscience
    Hi everybody! I'm supposed to build some Django apps, that allow you to administer multiple sites through one backend. The contrib.sites framework is quite perfect for my purposes. I can run multiple instances of manage.py with different settings for each site; but how should django's admin deal with different settings for different sites, eg. if they have different sets of languages, a different (default) language? So there are some problem s to face if you have to work on objects coming from different sites in one admin... I think settings.ADMIN_FOR is supposed to be quite helpful for cases like this, but theres hardly any documentation about it and I think it's not really used in the actual Django version (?). So any ideas/solutions are welcome and much appreciated! Thanks a lot...

  • How to add a context processor from a Django app

    - by Edan Maor
    Say I'm writing a Django app, and all the templates in the app require a certain variable. The "classic" way to deal with this, afaik, is to write a context processor and add it to TEMPLATE_CONTEXT_PROCESSORS in the settings.py. My question is, is this the right way to do it, considering that apps are supposed to be "independent" from the actual project using them? In other words, when deploying that app to a new project, is there any way to avoid the project having to explicitly mess around with its settings?
