  • Implementing a listview inside a sliding drawer with a listview already present

    - by Parker
    I have an app whose main class extends ListActivity: public class GUIPrototype extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Cursor c = managedQuery(People.CONTENT_URI, null, null, null, null); String[] from = new String[] {People.NAME}; int[] to = new int[] { R.id.row_entry }; SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.drawer,c,from,to); setListAdapter(adapter); getListView().setTextFilterEnabled(true); } } I have a sliding drawer included in my XML, and I'm trying to get a separate listview to appear in the sliding drawer. I'm trying to populate the second listview using an inflater: View inflatedView = View.inflate(this, R.layout.main, null); ListView namesLV = (ListView) inflatedView.findViewById(R.id.content); String[] names2 = new String[] { "CS 345", "New Tag", "Untagged" }; ArrayAdapter<String> bb = new ArrayAdapter<String>(this, R.layout.main, R.id.row_entry, names2); namesLV.setAdapter(bb); This compiles, and runs, but the slidingdrawer is completely blank. My XML follows: <SlidingDrawer android:id="@+id/drawer" android:handle="@+id/handle" android:content="@+id/content" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:layout_gravity="bottom"> <ImageView android:id="@id/handle" android:layout_width="48px" android:layout_height="48px" android:background="@drawable/icon"/> <ListView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@id/content"/> </SlidingDrawer> I feel like I'm missing a vital step. I haven't found any resources on my problem by Googling, so any help would be greatly appreciated.

  • dinamically resizing row height in QTreeWidget/QTreeView during edinitg items

    - by serge
    Hi everyone, I have some problems with sizing row's height in QTreeWidget. I use QStyledItemDelegate with QPlainTextEdit. During editing text in QPlainTextEdit i check for changes with a help of: rect = self.blockBoundingRect(self.firstVisibleBlock()) and if text it's height changes i need row in QTreeWidget also resizing. But i don't know how to inform TreeWidget or a Delegate about changes, i even tried to initialize editor with index, that i could use in a future, but it suddenly changes: class MyEditor(QPlainTextEdit): def __init__(self, index = None, parent=None): super(MyEditor, self).__init__(parent) self.index = index self.connect(self, SIGNAL("textChanged()"), self.setHeight) def setHeight(self): if self.index: rect = self.blockBoundingRect(self.firstVisibleBlock()) self.resize(rect.width(), rect.height()) self.emit(SIGNAL("set_height"), QSize(rect.width(), rect.height()), self.index) How can i bound editor's size changes with TreeWidget? And one more thing, by default all items (cells) in TreeWidget have -1 or some big value as default width. I need whole text in cell to be visible, so how can i limit it only by visible range and expand it in height? Thank you in advance, Serge

  • Using Joda DateTime as a Jersey parameter?

    - by HolySamosa
    I'd like to use Joda's DateTime for query parameters in Jersey, but this isn't supported by Jersey out-of-the-box. I'm assuming that implementing an InjectableProvider is the proper way to add DateTime support. Can someone point me to a good implementation of an InjectableProvider for DateTime? Or is there an alternative approach worth recommending? (I'm aware I can convert from Date or String in my code, but this seems like a lesser solution). Thanks. Solution: I modified Gili's answer below to use the @Context injection mechanism in JAX-RS rather than Guice. import com.sun.jersey.core.spi.component.ComponentContext; import com.sun.jersey.spi.inject.Injectable; import com.sun.jersey.spi.inject.PerRequestTypeInjectableProvider; import java.util.List; import javax.ws.rs.QueryParam; import javax.ws.rs.WebApplicationException; import javax.ws.rs.core.Context; import javax.ws.rs.core.Response; import javax.ws.rs.core.Response.Status; import javax.ws.rs.core.UriInfo; import javax.ws.rs.ext.Provider; import org.joda.time.DateTime; /** * Enables DateTime to be used as a QueryParam. * <p/> * @author Gili Tzabari */ @Provider public class DateTimeInjector extends PerRequestTypeInjectableProvider<QueryParam, DateTime> { private final UriInfo uriInfo; /** * Creates a new DateTimeInjector. * <p/> * @param uriInfo an instance of {@link UriInfo} */ public DateTimeInjector( @Context UriInfo uriInfo) { super(DateTime.class); this.uriInfo = uriInfo; } @Override public Injectable<DateTime> getInjectable(final ComponentContext cc, final QueryParam a) { return new Injectable<DateTime>() { @Override public DateTime getValue() { final List<String> values = uriInfo.getQueryParameters().get(a.value()); if( values == null || values.isEmpty()) return null; if (values.size() > 1) { throw new WebApplicationException(Response.status(Status.BAD_REQUEST). entity(a.value() + " may only contain a single value").build()); } return new DateTime(values.get(0)); } }; } }

  • Facebook FQL - How do I fetch the posts I made to a friend's wall

    - by simianarmy
    I have a facebook desktop app with some test users all having granted the stream_read & offline access permissions. I can easily retrieve posts to each users' stream & profile. What I cannot do easily is retrieve posts that a user has made to one of their friend's walls. In fact, this used to work with a rather complex multiquery, but has stopped working now, or is working only intermittently... Does anyone care to share their method if one exists or discuss what restrictions there might be to this type of complex querying?

  • C# PredicateBuilder Entities: The parameter 'f' was not bound in the specified LINQ to Entities quer

    - by Neothor
    I needed to build a dynamic filter and I wanted to keep using entities. Because of this reason I wanted to use the PredicateBuilder from albahari. I created the following code: var invoerDatums = PredicateBuilder.True<OnderzoeksVragen>(); var inner = PredicateBuilder.False<OnderzoeksVragen>(); foreach (var filter in set.RapportInvoerFilter.ToList()) { if(filter.IsDate) { var date = DateTime.Parse(filter.Waarde); invoerDatums = invoerDatums.Or(o => o.Van >= date && o.Tot <= date); } else { string temp = filter.Waarde; inner = inner.Or(o => o.OnderzoekType == temp); } } invoerDatums = invoerDatums.And(inner); var onderzoeksVragen = entities.OnderzoeksVragen .AsExpandable() .Where(invoerDatums) .ToList(); When I ran the code there was only 1 filter which wasn't a date filter. So only the inner predicate was filled. When the predicate was executed I got the following error. The parameter 'f' was not bound in the specified LINQ to Entities query expression. While searching for an answer I found the following page. But this is already implemented in the LINQKit. Does anyone else experienced this error and know how to solve it?

  • Three20 TTLauncherView Tutorial?

    - by Graeme
    Hi, I'm attempting to use TTLauncherView from the Facebook Three20 project in my app, but I'm not having much luck (I'm a bit of a newbie at this). Does anyone have any good tutorials at using it that I could read? FYI basically I need to pull images that a user chooses from the iPhone camera album, and display them as icons that when pressed lead to another view. Thanks.

  • cannot load JSTL taglib within embedded Jetty server

How can I get an embedded Jetty server up and running with full JSTL support?

  • Creating .NET 3.0 sub-applications within .NET 1.1 applications in IIS/ASP.Net

    - by Karen
    I am basically trying to do the same thing as this question, create a new application within a folder so it could be accessed as follows. * http://www.domain.com/ < Main App * http://www.domain.com/newapp < New App The problem is that newapp is reading the web.config from the Main App, which is causing errors because it doesn't have all the same dlls etc. For New App, in IIS, the starting point is set at /newapp, so I am not sure why it is reading the web.config from / at all. It is set as it's own application. I am testing this in IIS6 on XP Pro, so not sure if that makes a difference. The Main App is dotnet 1.1, and New App is 3.0. Edit: Adding 'inheritInChildApplications to <location doesn't work in 1.1, you get an error: Parser Error Message: Unrecognized attribute 'inheritInChildApplications'

  • Scrollbar problem with jquery ui dialog in Chrome and Safari

    - by alexis.kennedy
    I'm using the jquery ui dialog with modal=true. In Chrome and Safari, this disables scrolling via the scroll bar and cursor keys (scrolling with the mouse wheel and page up/down still works). This is a problem if the dialog is too tall to fit on one page - users on a laptop get frustrated. Someone raised this three months ago on the jquery bug tracker - http://dev.jqueryui.com/ticket/4671 - it doesn't look like fixing it is a priority. :) So does anyone (i) have a fix for this? (ii) have a suggested workaround that would give a decent usability experience? I'm experimenting with mouseover / scrollto on bits of the form, but it's not a great solution :( EDIT: props to Rowan Beentje (who's not on SO afaict) for finding a solution to this. jQueryUI prevents scrolling by capturing the mouseup / mousedown events. So this: $("dialogId").dialog({ open: function(event, ui) { window.setTimeout(function() { jQuery(document) .unbind('mousedown.dialog-overlay') .unbind('mouseup.dialog-overlay') ; }, 100); }, modal: true}); seems to fix it. Use at own risk, I don't know what other unmodal behaviour unbinding this stuff might allow.

  • What is the difference between System.Speech.Recognition and Microsoft.Speech.Recognition?

    - by Michael
    There are two similar namespaces and assemblies for speech recognition in .NET. I’m trying to understand the differences and when it is appropriate to use one or the other. There is System.Speech.Recognition from the assembly System.Speech (in System.Speech.dll). System.Speech.dll is a core DLL in the .NET Framework class library 3.0 and later There is also Microsoft.Speech.Recognition from the assembly Microsoft.Speech (in microsoft.speech.dll). Microsoft.Speech.dll is part of the UCMA 2.0 SDK I find the docs confusing and I have the following questions: System.Speech.Recognition says it is for "The Windows Desktop Speech Technology", does this mean it cannot be used on a server OS or cannot be used for high scale applications? The UCMA 2.0 Speech SDK ( http://msdn.microsoft.com/en-us/library/dd266409%28v=office.13%29.aspx ) says that it requires Microsoft Office Communications Server 2007 R2 as a prerequisite. However, I’ve been told at conferences and meetings that if I do not require OCS features like presence and workflow I can use the UCMA 2.0 Speech API without OCS. Is this true? If I’m building a simple recognition app for a server application (say I wanted to automatically transcribe voice mails) and I don’t need features of OCS, what are the differences between the two APIs?

  • Multiple Silverlight Unit Test Projects in Solution

    - by IUnknown
    I am building out a number of Silverlight 4.0 libraries that are part of the same solution. I like to break them into separate projects and have a Unit Test project for each: SolutionX -LibraryProject1 ---Class1.cs ---Class2.cs -LibraryProject1.Test ---Tests1.cs ---Tests2.cs -LibraryProject2 ---Class1.cs ---Class2.cs ---CLass3.cs -LibraryProject2.Test ---Tests1.cs ---Tests2.cs ---Tests3.cs -LibraryProject3 ---Class1.cs -LibraryProject3.Test ---Tests1.cs This works great when using VS regular test projects and infrastructure because I can create and execute list of test that are aggregated from each Test project. But with the Silverlight Unit Test Framework since the Silverlight Unit Test Project must be the "start up project" I cannot figure how to run a collection of tests from each test project in one go. I have to run each separately then switch the starting project each time. I would prefer to avoid create complex build scripts or build definitions - is there a way to run all the tests at once? -Thanks

  • jquery nested sortable

Point it the nestedSortable doesn't work any longer. So my question is tri fold does anyone know if the folks at jquery have implemented a nested sortable I haven't seen anything. or does anyone know how to fix the b-hind version or know of something better / light weight to accomplish the same goals would like something compatible with lastest jquery-ui EDIT: it appears as though the lastest version of jquery-ui-sortable supports nested sorting !!!

  • Exclude a directory from a rewriterule using ISAPI rewrite 3

    - by mludd
    Basically I've recently added the below rule in my httpd.conf for ISAPI rewrite on an IIS server to make sure that it always defaults to lower-case file and directory names. RewriteRule ^(.*[A-Z].*)$ $1 [CL,R=301,L] This is all fine and dandy for every part of the site except for one directory which we can call /MisbehavingDir, the code in this particular directory is filled with mixed-case filenames and lots of server- and client-side scripting that would have to be rewritten to use all lower-case in order to work properly (with the RewriteRule above it seems to hit a couple of 301s in the wrong places which causes that part of the site to function poorly to say the least). Since I'm not in the mood for rewriting that part of the site I'd love to find a good way to modify the above regex so that it matches everything except paths starting with MisbehavingDir and since my regex-fu isn't really good enough I figured I'd ask here. Is there a simple "beautiful" solution to this that anyone wants to share or should I just set aside several days to rewrite the app, then test it and go through that whole dance?

  • In the Xcode SplitView template for an iPad app, how do I add a Date Picker control to the Root View

    - by Dr Dork
    I'm diving into iPhone OS development on the iPad and one of the things I'm playing with is the SplitView template. The template provides a window with a UISplitView view, containing the Root View (on the left of the window) and the Detail View (on the right of the window). The Root View is a subclass of a TableView. Rather than having the entire Root View consist of a TableView, I'd like it to contain a DatePicker view along with the TableView under it. When I go into IB and try and drop a DatePicker into the Root View, it won't let me. It will only let me add a DatePicker view to the Detail View. Why wont IB let me drop a DatePicker view into the Root View? How can I add a DatePicker to the RootView in addition to the TableView? I'm still learning this new platform, so I apologize if these questions are absurd in any way. Thanks so much in advance for your help, I'm going to continue researching these questions right now.

  • How to populate a generic list of objects in C# from SQL database

    - by developr
    I am just learning ASP.NET c# and trying to incorporate best practices into my applications. Everything that I read says to layer my applications into DAL, BLL, UI, etc based on separation of concerns. Instead of passing datatables around, I am thinking about using custom objects so that I am loosely coupled to my data layer and can take advantage of intellisense in VS. I assume these objects would be considered DTOs? First, where do these objects reside in my layers? BLL, DAL, other? Second, when populating from SQL, should I loop through a data reader to populate the list or first fill a data table, then loop through the table to populate the list? I know you should close the database connection as soon as possible, but it seems like even more overhead to populate the data table and then loop through that for the list. Third, everything I see these days says use Linq2SQL. I am planning to learn Linq2SQL, but at this time I am working with a legacy database that doesn't have foreign keys setup and I do not have the ability to fix it atm. Also, I want to learn more about c# before I start getting into ORM solutions like nHibernate. At the same time I don't want to type out all the connection and SQL plumbing for every query. Is it ok to use the Enterprise DAAB for now?
