  • Run Google-apps-script on Google-Spreadsheet event?

    - by jdk
    If I create a Google apps script, can I hook it up to Google spreadsheet to run based on an event, or must I manually invoke it? I don't know if Google spreadsheet supports any events. For example: a Google app script that strikes out rows in the spreadsheet that have been marked completed by way of a column having the digit 1 beside completed rows. I would like this to run whenever a row is modified, or even when the spreadsheet is first loaded.

  • pyQt4: QWidget subclass not responding to new setStyleSheet() background colour

    - by Ronny
    I am having an issue with PyQt4. I want to create a new widget within a window, and I want this widget to have a custom color. When i create a subclass of the QWidget class, and instantiate it, I am not able to change its background color through the setStyleSheet() function. When I instantiate a new QWidget object, I have no problems in changing its background color. But i dont want an ordinary QWidget object.I want to create my own subclass of QWidget. When i create a subclass of a QPushButton, I am also able to change its background color using the setStyleSheet() function. There are no error messages or warnings in the console window, it just refuses to work properly without any indication as to why. So what i would like to know is why is it that i can change the background color of a widget if i simply create a QWidget object, or a subclass of QPushButton, but not when i create a subclass of QWidget. And how can i therefore change the background color of an object that is a subclass of QWidget? Is it maybe something specific to the version of python or PyQt that i am using? Is it a bug in the library? or some flaw in the way that i am writing my code? I am using python 2.6.4 and PyQt4 Below is an example of the code that leads me to trouble. There are three widgets within the window one below the other. The parent widget is set with background color of green. The top widget is set to red, the middle one, is the subclass of QWidget, which should be blue, but it appears invisible because it takes on the color of the parent window for some reason. and the bottom widget is a subclass of QPushButton and is white. import sys from PyQt4 import QtGui, QtCore ################################################################################ #--------------------------------------------------------- CUSTOM WIDGET CLASS 1 class CustomWidget(QtGui.QWidget): def __init__(self, parent): QtGui.QWidget.__init__(self, parent) # some custom properties and functions will follow ################################################################################ #--------------------------------------------------------- CUSTOM WIDGET CLASS 2 class CustomWidget2(QtGui.QPushButton): def __init__(self, parent): QtGui.QPushButton.__init__(self, parent) # some custom properties and functions will follow ################################################################################ #----------------------------------------------------------- PARENT WIDGET CLASS class Parent(QtGui.QWidget): def __init__(self, parent=None): #---------------------------------------------------------- SETUP WINDOW QtGui.QWidget.__init__(self, parent) self.resize(500, 340) self.setStyleSheet("QWidget {background-color: #00FF00}") #-------------------------------------------------- SETUP DEFAULT WIDGET wid1 = QtGui.QWidget(self) wid1.setGeometry(10, 10, 480, 100) wid1.setStyleSheet("QWidget {background-color: #FF0000 }") #------------------------------------------------- SETUP CUSTOM WIDGET 1 wid2 = CustomWidget(self) wid2.setGeometry(10, 120, 480, 100) wid2.setStyleSheet("QWidget {background-color: #0000FF }") for i in dir(wid2): print i #------------------------------------------------- SETUP CUSTOM WIDGET 2 wid3 = CustomWidget2(self) wid3.setGeometry(10, 230, 480, 100) wid3.setStyleSheet("QWidget {background-color: #FFFFFF }") ################################################################################ #-------------------------------------------------------------------------- MAIN app = QtGui.QApplication(sys.argv) win = Parent() win.show() app.exec_()

  • How can we create iPhone-like spinners in android?

    - by greg7gkb
    Default spinners on the iPhone look a lot better than on Android. It looks like at least one Android app (UrbanSpoon) has been able to replicate this control, and it's awesome: http://www.urbanspoon.com/android Anyone have any ideas on how to create this? Code would be helpful. Thanks, -g

  • Silverlight 3 localization configuration

    - by Yannic
    I would like to know how I can configure my Silverlight application to be able to change the UICulture of the current thread without having to recompile the application. If I set the current thread culture in the app.xaml, I need to recompile each time to change the culture. If I add an Application Settings, how can I retrieve that information on the client to be able to change the current thread culture info? any ideas ?

  • CherryPy sessions for same domain, different port

    - by detly
    Consider the script below. It will launch two subprocesses, each one a CherryPy app (hit Ctrl+C or whatever the KeyboardInterrupt combo is on your system to end them both). If you run it with CP 3.0 (taking care to change the 3.0/3.1 specific lines in "StartServer"), then visit: http://localhost:15002/ ...you see an empty dict. Then visit: http://localhost:15002/set?val=10 http://localhost:15002/ ...and you see the newly populated dict. Then visit: http://localhost:15012/ ...and go back to http://localhost:15002/ ...and nothing has changed. If you try the same thing with CP 3.1 (remember the lines in "StartServer"!), when you get to the last step, the dict is now empty. This happens in Windows and Debian, Python 2.5 and 2.6. You can try all sorts of things: changing to file storage, separating the storage paths... the only difference it makes is that the sessions might get merged instead of erased. I've read another post about this as well, and there's a suggestion there to put the session tools config keys in the app config rather than the global config, but I don't think that's relevant to this usage where the apps run independently. What do I do to get independent CherryPy applications to NOT interfere with each other? Note: I originally asked this on the CherryPy mailing list but haven't had a response yet so I'm trying here. I hope that's okay. import os, os.path, socket, sys import subprocess import cgi import cherrypy HTTP_PORT = 15002 HTTP_HOST = "127.0.0.1" site1conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '1', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} site2conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT + 10, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '2', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} class Home(object) : def __init__(self, key): self.key = key @cherrypy.expose def index(self): return """\ <html> <body>Session: <br>%s </body> </html> """ % cgi.escape(str(dict(cherrypy.session))) @cherrypy.expose def set(self, val): cherrypy.session[self.key.upper()] = val return """\ <html> <body>Set %s to %s</body> </html>""" % (cgi.escape(self.key), cgi.escape(val)) def StartServer(conf, key): cherrypy.config.update(conf) print 'Starting server (%s)' % key cherrypy.tree.mount(Home(key), '/', {}) # Start the web server. #### 3.0 # cherrypy.server.quickstart() # cherrypy.engine.start() #### #### 3.1 cherrypy.engine.start() cherrypy.engine.block() #### def Main(): # Start first webserver proc1 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "1"]) proc2 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "2"]) proc1.wait() proc2.wait() if __name__ == "__main__": print sys.argv if len(sys.argv) == 1: # Master process Main() elif(int(sys.argv[1]) == 1): StartServer(site1conf, 'magic') elif(int(sys.argv[1]) == 2): StartServer(site2conf, 'science') else: sys.exit(1)

  • Does iPhone support "greying out" inactive controls?

    - by iter
    I have a control that goes inactive under some conditions in my iPhone app. I can [setUserInteractionEnabled: NO] on it and it doesn't respond to touches. Its appearance does not change however. Other environments I am familiar with "grey out" inactive controls. I wonder what is the idiomatic way to hint to the user that the control is inactive.

  • Chaining IQueryables together

    - by Matt Greer
    I have a RIA Services based app that is using Entity Framework on the server side (possibly not relevant). In my real app, I can do something like this. EntityQuery<Status> query = statusContext.GetStatusesQuery().Where(s => s.Description.Contains("Foo")); Where statusContext is the client side subclass of DomainContext that RIA Services was kind enough to generate for me. The end result is an EntityQuery<Status> object who's Query property is an object that implements IQueryable and represents my where clause. The WebDomainClient is able to take this EntityQuery and not just give me back all of my Statuses but also filtered with my where clause. I am trying to implement this in a mock DomainClient. This MockDomainClient accepts an IQueryably<Entity> which it returns when asked for. But what if the user makes the query and includes the ad hoc additional query? How can I merge the two together? My MockDomainClient is (this is modeled after this blog post) ... public class MockDomainClient : LocalDomainClient { private IQueryable<Entity> _entities; public MockDomainClient(IQueryable<Entity> entities) { _entities = entities; } public override IQueryable<Entity> DoQuery(EntityQuery query) { if (query.Query == null) { return _entities; } // otherwise want the union of _entities and query.Query, query.Query is IQueryable // the below does not work and was a total shot in the dark: //return _entities.Union(query.Query.Cast<Entity>()); } } public abstract class LocalDomainClient : System.ServiceModel.DomainServices.Client.DomainClient { private SynchronizationContext _syncContext; protected LocalDomainClient() { _syncContext = SynchronizationContext.Current; } ... public abstract IQueryable<Entity> DoQuery(EntityQuery query); protected override IAsyncResult BeginQueryCore(EntityQuery query, AsyncCallback callback, object userState) { IQueryable<Entity> localQuery = DoQuery(query); LocalAsyncResult asyncResult = new LocalAsyncResult(callback, userState, localQuery); _syncContext.Post(o => (o as LocalAsyncResult).Complete(), asyncResult); return asyncResult; } ... }

  • WPF Visual Studio Package gives error: Could not find endpoint element with name 'WCFname' and contr

    - by Andrei
    Hi everybody. This error has been covered before in other questions, however not for a Visual Studio package. Could not find endpoint element with name 'WCFname' and contract 'WCFcontract' in the ServiceModel client configuration section. I have a VS package project that needs to connect to a WCF service that provides some functionality. I add a reference to the WCF service and Visual Studio automatically creates the content for the configuration file. config file: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_IWCFSearchService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://localhost:8732/Design_Time_Addresses/WCFSearchServiceLibrary/Service1/" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IWCFSearchService" contract="WCFSearchServiceReference.IWCFSearchService" name="WSHttpBinding_IWCFSearchService"> <identity> <dns value="localhost" /> </identity> </endpoint> </client> </system.serviceModel> </configuration> However, when I run the application (in VS experimental mode) it doesn't seem to take the provided configuration file (app.config). Everytime it just throws this error: Could not find endpoint element with name 'WSHttpBinding_IWCFSearchService' and contract 'WCFSearchServiceReference.IWCFSearchService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element. My guess is that it's taking the configuration file for Visual Studio (since it is running VS experimental mode). So yeah...why isn't it recognizing the app.config file and how could I make the application to recognize it? Any help would be very welcomed as I have already tried to fix this for some time. Thanks.

  • Youtube video processing on iPhone

    - by Chonch
    Hey In my iPhone app, I want to load a video from youtube, perform some basic image processing on it and display it to the user. I am using openCV to do my image processing, and I know I can use it for grabbing all of the frames from the video as well (cvRetrieveFrame). My only problem is that cvRetrieveFrame expects to get its source of type CvCapture* which can be created either by a camera source or by a file name. How can I set a youtube video file as the source for CvCapture*? Thanks,

    I have a UIImageView that starts off with an image (loading.png) specified in IB. When my app starts, a new image is downloaded from the internet to replace the existing one. I do the following to replace the image: if(object.imageView.image != nil){ [object.imageView.image release]; object.imageView.image = nil; } object.imageView.image = [UIImage imageNamed:@"downloadedimage.png"]; Is this the right way to re-set an image?

  • XCode Build and Run

    - by Josh
    I recently reinstalled OSX, and am having a slight annoyance with XCode. Before I reinstalled, I could just hit CMD + Enter, and it would build, then flip the main editor screen to the debugger, where it would show NSLogs, crashes, etc. Now, when I hit CMD + Enter, it just runs the app and stays in the code editor screen. Is there an option I'm missing? I've scoured the preferences, and can't seem to find anything.
