  • multiline gtk.Label ignores xalign=0.5

    - by thomas
    A gtk.Label can't be aligned in center when line-wrap is turned on. Example code: import pygtk pygtk.require('2.0') import gtk class testwin(gtk.Window): def __init__(self): gtk.Window.__init__(self) width,height = 300,300 self.set_size_request(width,height) self.set_position(gtk.WIN_POS_CENTER) self.set_title("test window") label = gtk.Label("test text") label.set_line_wrap(True) label.set_justify(gtk.JUSTIFY_CENTER) label.set_alignment(0.5,0.5) label.connect("size-allocate",lambda l,s: l.set_size_request(s.width-1, -1)) self.add(label) self.connect("destroy", gtk.main_quit) self.show_all() testwin() gtk.main() It looks like this, that means, it's aligned left: http://m45.img-up.net/?up=pic122x97.png If you comment out line 14 (set_line_wrap) everything is perfectly fine: http://o54.img-up.net/?up=pic2y00p9.png Please note that yalign works fine. So it seems like the first argument in the gtk.Misc.set_alignment-function has no effect when line wrap is turned on. Using Fedora 16, 64bit, gtk 3.2.4, pygtk 2.24.0, python 2.7.2 Question: Is this intended or a bug? How is it supposed to be made or is a workaround available?

  • MySQL + MyISAM table size question

    - by alessandro ferrucci
    Hello, I have a test table. The test table is as follows: CREATE TABLE mytest ( num1 int(10) unsigned NOT NULL, KEY key1 (num1) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; I inserted 50 million rows in this table. When I do show table status the avg_row_length is 7. I was expecting to see 4 since mySQL uses 4 bytes for integers. Does the key have an effect on the avg_row_length? When I look at my .MYD file the size is 334 MB which is exactly what it should be given that the avg_row_length is 7, however I was really expecting to see 190 MB given that I only have an int. +----------------+--------+---------+------------+----------+----------------+-------------+------------------+--------------+-----------+----------------+---------------------+---------------------+------------+-------------------+----------+----------------+---------+ | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment | +----------------+--------+---------+------------+----------+----------------+-------------+------------------+--------------+-----------+----------------+---------------------+---------------------+------------+-------------------+----------+----------------+---------+ | mytest | MyISAM | 10 | Fixed | 50000000 | 7 | 350000000 | 1970324836974591 | 600518656 | 0 | NULL | 2010-05-22 09:15:06 | 2010-05-22 19:32:53 | NULL | latin1_swedish_ci | NULL | | | I have included the output of show table status for mytest table.

  • Can't print elements in a DIV tag

    - by Mckenzi
    I am using a Drag-able and re-sizeable DIV's in this HTML file. Where the user will place the DIV tag to his desired place in a main parent DIV tag. Now I want to print this main DIV tag, but the problem is that the code which I'm using to PRINT this main DIV is printing in a sequence, like not the way user has arranged the DIV's. Also it doesn't take up the main DIV background IMAGE. here is the code.

  • NUnit not running Suite tests

    - by Assaf Lavie
    I've created a test suite in NUnit that references several distinct unit test fixtures in various assemblies. I've pretty much used the example code from NUnit's docs: namespace NUnit.Tests { using System; using NUnit.Framework; using System.Collections; public class AllTests { [Suite] public static IEnumerable Suite { get { ArrayList suite = new ArrayList(); suite.Add(new VisionMap.DotNet.Tests.ManagedInteropTest.DotNetUtilsTest()); return suite; } } } } My goal is to add several tests to the list above so I can run them all in a batch. But when I try to load the DLL in NUnit's GUI I get this: What am I doing wrong? I'm using nunit 2.5.0.9122.

  • Is Android AVD's firewall somehow more restricted to real Android firewall?

    - by hhh
    I have a TCP server running in AVD and a TCP client running in AVD. AVD client dies because the connection refused so we are doubting some restricted firewall settings. I turned off the firewall in my Debian -laptop with this here but it did not fix the problem so some issue with Android -emulator, intro here. How can I make a TCP connection from one AVD to another AVD in the same laptop in Android? Grap the code & Minimal Working Example: You can find the sources here: import to Eclipse, set up two pieces of 2.3.3 AVDs, set up Test-running-configurations for server and client. Then "Run as Configuration" and you should see this bug. I don't have a physical Android -phone to test the code so I cannot comment whether it works with real Androids.

  • getjson and servers

    - by gheil.apl
    Is getJSON only useful for those who control a server? Is there any other alternative for getting data from a file? i tried $.getJSON("good.json", function(data){ out=out+"good.json: "+data + ","; }); where good.json = {"a":"1","b":"2"} and got a result of 'null' for data. These all are valid JSON files, and all give null when used in the above: good.htm assoc.json assoc.js stub.json stub.js test.js test.txt and all get a null result... The above is in an interactive setting at http://jsbin.com/dbJSON/8/edit the output (of null) is to be had by clicking 'output'.

    Hi, I have an android application that shows a grid view that shows: 1 2 3 4 GridView gridview=(GridView)findViewById(R.id.GridView_test); DataBaseHelper dbhelper=new DataBaseHelper(this); ArrayList<String> test=new ArrayList<String>(5); backlinksadapter.add("1"); backlinksadapter.add("2"); backlinksadapter.add("3"); backlinksadapter.add("4"); ArrayAdapter mAdapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, test); gridview.setAdapter(mAdapter); By the moment is working, but i would like to show foreach line of the grid, 2 columns with the values of a 2 dimensional array (something like the GridView in ASP.Net - as datasource -). I would like to show: 1 | Person 1 2 | Person 2 3 | Person 3 4 | Person 4 Any idea? Thanks in advance. Jose.

  • Testing objects for changes

    - by David Veeneman
    I have an application that needs to determine whether a user has made a change to an object. So, when the object is first loaded, I create a deep copy (using serialization/deserialization) and save the copy to a separate field. The copy becomes myCurrentObject, and the original becomes myOriginalObject. Now I need to test myCurrentObject for changes, which I plan to do by comparing it to myOriginalObject. All I need is a boolean result indicating whether any changes have been made. I have already determined that a simple hashcode comparison won't work. GetHashCode() generates different results for the two objects, even when there are no changes. I am getting ready to write a method to do a property-by-property comparison, but before I do, I thought I would check to see if there is a simpler and more reusable way to test myCurrentObject to see if it has changed from myOriginalObject. Any suggestions? Thanks for your help.

  • Can I configure NUnit so that Debug.Fail doesn't show a message box when I run my tests?

    - by panamack
    I have this property: public SubjectStatus Status { get { return status; } set { if (Enum.IsDefined(typeof(SubjectStatus), value)) { status = value; } else { Debug.Fail("Error setting Subject.Status", "There is no SubjectStatus enum constant defined for that value."); return; } } } and this unit test [Test] public void StatusProperty_StatusChangedToValueWithoutEnumDefinition_StatusUnchanged() { Subject subject = new TestSubjectImp("1"); // assigned by casting from an int to a defined value subject.Status = (SubjectStatus)2; Assert.AreEqual(SubjectStatus.Completed, subject.Status); // assigned by casting from an int to an undefined value subject.Status = (SubjectStatus)100; // no change to previous value Assert.AreEqual(SubjectStatus.Completed, subject.Status); } Is there a way I can prevent Debug.Fail displaying a message box when I run my tests, but allow it to show me one when I debug my application?

  • What is a good way to measure game virality?

    - by Chris Garrett
    I have added some social features to an iPhone game (Lexitect if you're curious), such as email, Twitter, and Facebook integration for sharing high scores. Along with these features, I am measuring how many times users make it to each step. The goal of these features are to make the game more viral, and I am trying to get to a measure of game virality. I would think that a game virality metric would produce a number based on 1.0, where 1.0 = zero viral growth, and 1.01 would represent 1% viral growth over some unit of time. How is virality normally measured, and in what units? How is time capped on the metric? i.e. if I gave each player a year to determine how many recommendations they make, I wouldn't get any real numbers for a year from the time I start tracking it. Are there any standards for tracking virality in a meaningful way?

  • Where to put my xUnit tests for an F# assembly?

    - by Benjol
    I'm working on my first 'real' F# assembly, and trying to do things right. I've managed to get xUnit working too, but currently my test module is inside the same assembly. This bothers me a bit, because it means I'll be shipping an assembly where nearly half the code (and 80% of the API) is test methods. What is the 'right' way to do this? If I put the tests in another assembly, I think that means I have to expose internals that I'd rather keep private. I know that in C# there is a friend mechanism for tests (if that's the right terminology), is there an equivalent in F#? Alternatively, can anyone point me to an example project where this is being done 'properly'?

  • FluentNhibernate many-to-many mapping - resolving record is not inserted

    Hi, I have a many-to-many mapping defined (only relevant fields included): // MODEL: public class User : IPersistentObject { public User() { Permissions = new HashedSet<Permission>(); } public virtual int Id { get; protected set; } public virtual ISet<Permission> Permissions { get; set; } } public class Permission : IPersistentObject { public Permission() { } public virtual int Id { get; set; } } // MAPPING: public class UserMap : ClassMap<User> { public UserMap() { Id(x => x.Id); HasManyToMany(x => x.Permissions).Cascade.All().AsSet(); } } public class PermissionMap : ClassMap<Permission> { public PermissionMap() { Id(x => x.Id).GeneratedBy.Assigned(); Map(x => x.Description); } } The following test fails as there is no record inserted into User_Permission table: [Test] public void AddingANewUserPrivilegeShouldSaveIt() { var p1 = new Permission { Id = 123, Description = "p1" }; Session.Save(p1); var u = new User { Email = "[email protected]" }; u.Permissions.Add(p1); Session.Save(u); var userId = u.Id; Session.Evict(u); Session.Get<User>(userId).Permissions.Should().Not.Be.Empty(); } The SQL executed is (SQLite): INSERT INTO "Permission" (Description, Id) VALUES (@p0, @p1);@p0 = 'p1', @p1 = 1 INSERT INTO "User" (Email) VALUES (@p0); select last_insert_rowid();@p0 = '[email protected]' SELECT user0_.Id as Id2_0_, user0_.Email as Email2_0_ FROM "User" user0_ WHERE user0_.Id=@p0;@p0 = 1 SELECT permission0_.UserId as UserId1_, permission0_.PermissionId as Permissi2_1_, permission1_.Id as Id4_0_, permission1_.Description as Descript2_4_0_ FROM User_Permissions permission0_ left outer join "Permission" permission1_ on permission0_.PermissionId=permission1_.Id WHERE permission0_.UserId=@p0;@p0 = 1 We can clearly see that there is no record inserted into the User_Permissions table where it should be. Not sure what I am doing wrong and need an advice. So can you please help me to pass this test. Thanks, Dmitriy.

  • Hints to properly design UML class diagram

    - by mic4ael
    Here is the problem. I have just started learning UML and that is why I would like to ask for a few cues from experienced users how I could improve my diagram because I do know it lacks a lot of details, it has mistakes for sure etc. Renovation company hires workers. Each employee has some kind of profession, which is required to work on a particular position. Workers work in groups consisting of at most 15 members - so called production units, which specializes in a specified kind of work. Each production unit is managed by a foreman. Every worker in order to be able to perform job tasks needs proper accessories. There are two kind of tools - light and heavy. To use heavy tools, a worker must have proper privileges. A worker can have at most 3 light tools taken from the warehouse.

  • How do I mock memory allocation failures ?

    - by Andrei Ciobanu
    I want to extensively test some pieces of C code for memory leaks. On my machine I have 4 Gb of RAM, so it's very unlikely for a dynamic memory allocation to fail. Still I want to see the comportment of the code if memory allocation fails, and see if the recover mechanism is "strong" enough. What do you suggest ? How do I emulate an environment with lower memory specs ? How do i mock my tests ? EDIT: I want my tests to be code independent. I only have "access" to return values for different functions in the library I am testing. I am not supposed to write "test logic" inside the code I am testing.

  • jQuery Rollovers Not Preloading

    - by zuk1
    $('.ro').hover( function(){ t = $(this); t.attr('src',t.attr('src').replace(/([^.]*)\.(.*)/, "$1_o.$2")); }, function(){ t = $(this); t.attr('src',t.attr('src').replace('_o','')); } ); I use this code so that (for examle) test.gif with the class 'ro' would change to test_o.gif on rollover, the problem is when the images aren't in the cache there is lag on rollover and rolloff. Basically if I clear my cache and visit the test page, everytime I rollover and rolloff the image it is loading the file each time, so you could sit there for hours and it would still be loading the rollover images each time. However, when I refresh the page and the images are now in the cache it works instantly, which is what I need to achieve. I've tried using this http://flesler.blogspot.com/2008/01/jquerypreload.html plugin to preload the images with this $.preload('.ro'); code, but it seems to have no effect. Any ideas?

  • VB.Net variable declaration

    - by dcp
    I notice that both of these compile without any compiler warnings or errors, even with Option Strict and Option Explicit both turned on: Dim x As Exception = New Exception("this is a test") Dim y = New Exception("this is another test") My question is, is it more proper to use the first way (see variable x) or the second way (see variable y)? My guess is that VB doesn't need the As clause since the variable is being initialized in place, so the compiler can infer the type. I tend to like the first way as it just "feels" right and is more consistent with other languages like C#, just wondered if there was some good reason for one way over the other. I guess it's really personal choice.

  • Setting amount of time to pass when sending emails in a loop

    - by Obay
    Forgive me for this noob question, but is there such a setting that sets a certain amount of time (e.g. milli/seconds) that has to pass in between sending emails through a script? How is that setting called and where do I change that setting? I'll give an example: I used to have a PHP script that sends emails like so: for ($i=0; $i<count($emails); $i++) { mail($email[$i],'test','test'); } It turned out that not all emails were sent successfully because the script ran so fast that there was not enough time in between sending emails that was required by the server. Did I make sense?

  • MS SQL: Mitigating schema changes/upgrades

    - by bradhe
    I haven't spent a ton of time researching this yet, mostly looking for best practices on upgrading/changing DB schemas. We're actively developing a new product and as such we often have additions or changes to our DB schema. We also have many copies of the DB -- one for the test environment, one for the prod environment, dev environments, you name it. We don't really want to have to blow away test data every time we want to make a change to the DB. s Are there good ways of automating this or handling this? None of us have really ever had to deal with this so...

  • How do you handle increasingly long compile times when working with templates?

    - by Ghita
    I use Visual Studio 2012 and he have cases where we added templates parameters to a class "just" in order to introduce a "seam point" so that in unit-test we can replace those parts with mock objects. How do you usually introduce seam points in C++: using interfaces and/or mixing based on some criteria with implicit interfaces by using templates parameters also ? One reason to ask this is also because when compiling sometimes a single C++ file (that includes templates files, that could also include other templates) results in an object file being generated that takes in the order of around 5-10 seconds on a developer machine. VS compiler is also not particularly fast on compiling templates as far as I understand, and because of the templates inclusion model (you practically include the definition of the template in every file that uses it indirectly and possibly re-instantiate that template every time you modify something that has nothing to do with that template) you could have problems with compile times (when doing incremental compiling). What are your ways of handling incremental(and not only) compile time when working with templates (besides a better/faster compiler :-)).
