  • How to display and change an icon inside a python Tk Frame

    - by codingJoe
    I have a python Tkinter Frame that displays several fields. I want to also add an red/yellow/green icon that will display the status of an external device. The icon is loaded from a file called ICON_LED_RED.ico. How do I display the icon in my frame? How do I change the icon at runtime? for example replace BitmapImage('RED.ico') with BitmapImage('GREEN.ico') class Application(Frame): def init(self, master=None): Frame.__init__(self, master) self.pack() self.createWidgets() def createWidgets(self): # ...other frame code.. works just fine. self.OKBTN = Button(self) self.OKBTN["text"] = "OK" self.OKBTN["fg"] = "red" self.OKBTN["command"] = self.ok_btn_func self.OKBTN.pack({"side": "left"}) # when I add the following the frame window is not visible # The process is locked up such that I have to do a kill -9 self.statusFrame = Frame(self, bd=2, relief=RIDGE) Label(self.statusFrame, text='Status:').pack(side=LEFT, padx=5) self.statIcon = BitmapImage('data/ICON_LED_RED.ico') Label (self.statusFrame, image=self.statIcon ).grid() self.statusFrame.pack(expand=1, fill=X, pady=10, padx=5)

  • Installing mySQL on mac for use with python

    - by Paul Patterson
    I am aware that there are umpteen similar questions here, and on other forums, but none of them have been able to help me. I simply want to install mySQL on my mac (running snow leopard 10.6.5) for use with Python. So far I have: 1) downloaded and installed [mysql-5.5.8-osx10.6-x86_64.dmg] (I have also accidentally downloaded and installed [mysql-5.1.54-osx10.6-x86_64.dmg]) 2) downloaded and installed [mySQL-python-1.2.3] 3) added the following to my .bash_profile: [export PATH=$PATH:/usr/local/mysql/bin] but when i run:import mySQLdb in terminal I am met with the following message: Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named mySQLdb Can anyone help?

  • Python - Is there a better/efficient way to find a node in tree?

    - by Sej P
    I have a node data structure defined as below and was not sure the find_matching_node method is pythonic or efficient. I am not well versed with generators but think there might be better solution using them. Any ideas? class HierarchyNode(): def __init__(self, nodeId): self.nodeId = nodeId self.children = {} # opted for dictionary to help reduce lookup time def addOrGetChild(self, childNode): return self.children.setdefault(childNode.nodeId,childNode) def find_matching_node(self, node): ''' look for the node in the immediate children of the current node. if not found recursively look for it in the children nodes until gone through all nodes ''' matching_node = self.children.get(node.nodeId) if matching_node: return matching_node else: for child in self.children.itervalues(): matching_node = child.find_matching_node(node) if matching_node: return matching_node return None

  • what is a fast way to output h5py dataset to text?

    - by user362761
    I am using the h5py python package to read files in HDF5 format. (e.g. somefile.h5) I would like to write the contents of a dataset to a text file. For example, I would like to create a text file with the following contents: 1,20,31,75,142,324,78,12,3,90,8,21,1 I am able to access the dataset in python using this code: import h5py f = h5py.File('/Users/Me/Desktop/thefile.h5', 'r') group = f['/level1/level2/level3'] dset = group['dsetname'] My naive approach is too slow, because my dataset has over 20000 entries: # write all values to file for index in range(len(dset)): # do not add comma after last value if index == len(dset)-1: txtfile.write(repr(dset[index])) else: txtfile.write(repr(dset[index])+',') txtfile.close() return None Is there a faster way to write this to a file? Perhaps I could convert the dataset into a NumPy array or even a Python list, and then use some file-writing tool? (I could experiment with concatenating the values into a larger string before writing to file, but I'm hoping there's something entirely more elegant)

  • How to check with PHP does a SQL database already have

    - by Dan Horvat
    I've tried to find the answer to this question but none of the answers fit. I have two databases, one has 15.000.000 entries and I want to extract the necessary data and store it in a much smaller database with around 33.000 entries. Both databases are open at the same time. Or at least they should be. While having the big database open and extracting the entries from it, is it possible to check whether the value already exists in the smaller database? I just need some generic way which checks that.

  • library interposition with dlsym

    - by ZeeGeek
    I'm writing an interposition library to track the usage of some library functions in libc, such as open(), close(), connect(), etc. It works generally well on most of the applications. However, when I try it with PHP, using PHP's MySQL module in particular, none of the function calls to libc inside this module is been tracked (so no connect(), no socket(), etc.). 'strace' told me that the system calls socket(), connect(), etc., took place. Running 'file' on the module and libmysqlclient.so.16.0.0 said that they are all dynamically linked. So it shouldn't be a problem caused by static linkage. What might be the problem? I'm using Fedora 11 64-bit version. Thank you.

  • Embedded Google Earth Plug-Ins no longer working

    - by user1497162
    I really hope someone can help me. I just noticed that none of my website's Google Earth embedded plug-in's work anymore (in Safari, Chrome or Firefox)  All you can see now is blank space and small text that says "Information is temporarily unavailable." I have no idea why they would no longer be working.  Nothing has changed whatsoever. Example here: http://www.grandcanyonvirtualtour.com/_tours/phantom_ranch.html Any suggestions greatly appreciated!! Please note, I am not a coder -- I am a photographer who is learning how to integrate photographs into maps, so I apologize if any questions are elementary. Thanks, Sara I am on a MacBook Pro 2.4 GHz Intel Core i7; OS 10.7.4

  • How to change the sorting of a view using hook_views_pre_view()?

    - by RD
    I've got the following: function view_sorter_views_pre_view(&$view) { // don't need $items if ($view->name == 'MOST_RECENT') { $insert = array(); $insert[order] = 'DESC'; //SORT ORDER $insert[id] = 'title'; $insert[table] = 'node'; $insert[field] = 'title'; $insert[override] = array(); $insert[override][button] = 'Override'; $insert[relationship] = 'none'; unset ($view->display['default']->display_options['sorts']['title']); $view->display['default']->display_options['sorts']['title'] = $insert; } } Basically, I'm just changing the sort order... but this does not appear on the view when opening it. Any idea why?

  • Silverlight/WPF: Retreiving the size of a `UIElement` once it has been rendered on screen

    - by ondesertverge
    I have the following simple piece of code: var canvas = new Canvas(); foreach (var ztring in strings) { var textblock = new TextBlock(); textblock.Text = ztring; panel.Children.Add(textblock); textblock.Measure(infiniteSize); } At this point I would expect any of the size properties (Height/Width, ActualHeight/ActualWidth, DesiredSize, RenderSize) to give me the size of the textblock. None of them do. ActualHeight always gives 16.0 no matter what size font. ActualWidth changes according to the text length but not the font size. I change the font size on the parent container and not the TextBlock itself. I feel like I am missing some basic element of understanding the manipulation of silverlight elements from within the codebehind. The question is: how do I get the real actual pixel size of my TextBlock?

  • How to set the value of a wx.combobox by posting an event

    - by Adam Fraser
    The code below demonstrates the problem I am running into. I am creating a wx.ComboBox and trying to mimic it's functionality for testing purposes by posting a wxEVT_COMMAND_COMBOBOX_SELECTED event... this event strangely works fine for wx.Choice, but it doesn't do anything to the ComboBox. There doesn't appear to be a different event that I can post to the combobox, but maybe I'm missing something. I'm running this code on Python 2.5 on a Mac OSX 10.5.8 import wx app = wx.PySimpleApp() def on_btn(evt): event = wx.CommandEvent(wx.wxEVT_COMMAND_COMBOBOX_SELECTED,combobox.Id) event.SetEventObject(combobox) event.SetInt(1) event.SetString('bar') combobox.Command(event) app.ProcessPendingEvents() frame = wx.Frame(None) panel = wx.Panel(frame, -1) # This doesn't work combobox = wx.ComboBox(panel, -1, choices=['foo','bar']) # This works #combobox = wx.Choice(panel, -1, choices=['foo','bar']) combobox.SetSelection(0) btn = wx.Button(panel, -1, 'asdf') btn.Bind(wx.EVT_BUTTON, on_btn) sz = wx.BoxSizer() sz.Add(combobox) sz.Add(btn) panel.SetSizer(sz) frame.Show() app.MainLoop()

  • How do I specify a null relation in SQLAlchemy?

    - by Jesse
    Not sure what the correct title for this question should be. I have the following schema: Matters have a one-many relationship to WorkItems. WorkItems have a one-one (or one-zero) relationship to LineItems. I am trying to create the following relation between Matters and WorkItems Matter.unbilled_work_items = orm.relation(WorkItem, primaryjoin = (Matter.id == WorkItem.matter_id) and (WorkItem.line_item_id == None), foreign_keys = [WorkItem.matter_id, WorkItem.line_item_id], viewonly=True ) This throws: AttributeError: '_Null' object has no attribute 'table' That seems to be saying that the second clause in the primaryjoin returns an object of type _Null, but it seems to be expecting something with a "table" attribute. This seems like it should be pretty straightforward to me, am I missing something obvious?

  • What is the best way to read files in an EventMachine-based app?

    - by Theo
    In order not to block the reactor I would like to read files asynchronously, but I've found no obvious way of doing it using EventMachine. I've tried a few different approaches, but none of them feels right: Just read the file, it'll block the reactor, but what the hell, it's not that slow (unless it's a big file, and then it definitely is). Open the file for reading and read a chunk on each tick (but how much to read? too much and it'll block the reactor, too little and reading will get slower than necessary). EM.popen('cat some/file', FileReader) feels really weird, but works better than the alternatives above. In combination with the LineAndTextProtocol it reads lines pretty swiftly. EM.attach, but I haven't found any examples of how to use it, and the only thing I've found on the mailing list is that it's deprecated in favour of… EM.watch, which I've found no examples of how to use for reading files. How do you read files within a EventMachine reactor loop?

  • Silverlight 4 application on localhost runs extremely slow

    - by rams
    Silverlight 4 app running in IE8 and hosted on VS2010 internal webserver. The website takes atleast a minute to download the xap and code runs slow on client (IE8). I am running the app in debug mode and have turned intellitrace off. Symbol loading is also turned off. However if I kill the VS webserver, clean the solution, the app runs fast. 3 debugging sessions later, the app slows to a crawl. Have also tried turning off McAfee live scanning but no use. Looked in event log for any clue but found none. What could be the cause of the slowness? TIA rams

  • Trying to start a service on boot on Android

    I've been trying to start a service when a device boots up on android, but I cannot get it to work. I've looked a number of links online but none of the code is working.

  • Python - List and Loop in one def

    - by Dunwitch
    I'm trying to get the def wfsc_pod1 and wfsc_ip into the same def. I'm not quite sure how to approach the problem. I want wfsc_pod1 to display all the information for name, subnet and gateway. Then wfsc_ip shows the ip addresses below it. I also get a None value when I run it as it. Not sure why. Anything more pythonic is more appreciated. class OutageAddress: subnet = ["255.255.255.0", "255.255.255.1"] # Gateway order is matched with names gateway = ["192.168.1.1", "192.168.1.2", "192.168.1.3", "192.168.1.4", "192.168.1.5", "192.168.1.6", "192.168.1.7", "192.168.1.8", "192.168.1.9"] name = ["LOC1", "LOC2", "LOC3", "LOC4", "LOC5", "LOC6", "LOC7", "LOC8", "LOC9"] def wfsc_pod1(self): wfsc_1 = "%s\t %s\t %s\t" % (network.name[0],network.subnet[0],network.gateway[0]) return wfsc_1 def wfsc_ip(self): for ip in range(100,110): ip = "192.168.1."+str(ip) print ip network = OutageAddress() print network.wfsc_pod1() print network.wfsc_ip()

  • Whats the API Key for in Google Maps API V3?

    - by Brandon
    In the older version of the API, I'd have to insert the javascript into the page using something like this for just basic functionality to work: http://maps.google.com/maps?file=api&v=2&key=GoogleMapsAPIKey Where I had to configure the API key for each individual site. Looking at the documentation, it says to get a basic map working I just need this: http://maps.google.com/maps/api/js?sensor=true/false Where does the API key fit in? Do I need to worry about it if I just plan on using a basic map and marker and none of the more advanced functions?

  • Get a single element with PHP and XPath

    - by daliz
    Lots of tutorials around the net but none of them can explain me this: How do I select a single element (in a table, for example), having its absolute XPath? Example: I have this: /html/body/table/tbody/tr[2]/td[2]/table/tbody/tr/td/table[3]/tbody/tr/td/table/tbody/tr[3]/td/table/tbody/tr[4]/td[5]/span What's that PHP function to get the text of that element?! Really I could not find an answer. Found lots of guides and hints to get all the elements of the table, all the buttons of a form, etc, but not what I need. Thank you.

  • NHibernateUtil.Initialize and Table where clause (Soft Delete)

    - by Pascal
    We are using NHibernate but sometimes manually load proxies using the NHibernateUtil.Initialize call. We also employ soft delete and have a "where" condition on all our mapping to tables. SQL generated by NHibernate successfully adds the where condition (i.e. DELETED IS NULL) however we notice that NHibernateUtil.Initialize does not observe the constraints of the mapping files. i.e. None of the SQL generated by NHibernateUtil.Initialize observes our DELETED IS NULL condition. Is there something we're missing as we would really like to employ manual loading of some entity collections when the situation demands it. We are using FluentNhibernate for our mapping.

  • flash.media.Sound.play takes long time to return

    - by Fire Lancer
    I'm trying to play some sounds in my flash project through action script. However for some reason in my code the call to Sound.play takes from 40ms to over 100ms in extreme cases, which is obviously more than enough to be very noticeable whenever a sound is played. This happens every time a sound is played, not just when that sound is first played, so I dont think its because the Sound object is still loading data or anything like that... At the start I have this to load the sound: class MyClass { [Embed(source='data/test_snd.mp3')] private var TestSound:Class; private var testSound:Sound;//flash.media.Sound public function MyClass() { testSound = new TestSound(); } Then im just using the play method of the sound object to play it later on. testSound.play();//seems to take a long time to return This as far as I can tell is following the same process as other Flash programs I found, however none of them seem to have this problem. Is there something that I've missed that would cause the play() method to be so slow?

  • Debugging ASP.NET with IIS

    - by Ariel
    I've set up debugging in Visual Studio 2008 to IIS instead of the built in server so I can run url rewriting while developing (using IIRF). It took a while to get to work (changing permissions, reinstalling the .NET framework) but it was working. I turned off my machine, and now that it's back on the debugger won't start. I'm using Parallels with WinXP on an iMac. "Unable to start debugging on the web server. Could not start ASP.NET debugging. More information may be available by starting the project without debugging" I read a whole bunch of posts on SO as well as googled the subject but none seem to provide a working answer. Has anyone encountered this and knows how to get it to work? Thanks.

  • code deployment options

    - by bobinabottle
    We've been looking at automating our server and code deployments. We've already decided on puppet for our server configurations, but are looking for a more "push" style tool to use for code deployments. I'm currently looking at either using capistrano or fabric, but I'm not sure what would be the most mature to use? We deploy a number of different services, none of which are currenlty written in rails or django, so we don't mind about language. What would be the best one to build custom deployment scripts? Or have I missed another tool out there? We are also considering git pushing with hooks for deployment, but feel it will be limited/hacky in what we want to achieve with it. Any thoughts or experience would be great to hear. Cheers

  • jQuery UI - Accordion Display issues

    - by Dave Kiss
    My accordion is working properly, but I'm having a few CSS and JS issues that are prohibiting it from displaying correctly. http://jsfiddle.net/frEWQ/ The JS is applying .ui-corners-all to the H3 before the "kwick" div below it has finished collapsing, giving an odd cut-off border during the animation The margin-bottom applied to the "kwick" div to give spacing between each tab disappears when the tab is set to display:none, getting rid of the spacing... but I can't apply the margin-bottom to the header because it disconnects the header from the "kwick" div below it. Any suggestions? Modification to the JS/CSS? Thanks
