  • How to set specific column settings in JTable?

    - by HansDampf
    How can I make my JTable show specific stuff for each column? Can I use an Object for more than one column? I want to have a column showing the date (dd.mm.yyyy) and another to show the time (hh:mm) but as I have it now it only shows the String representation of the Date object as a whole. public class AppointmentTableModel extends AbstractTableModel { ... @Override public Object getValueAt(int rowIndex, int columnIndex) { return appointments.get(rowIndex).getByColumn(columnIndex); } } public class Appointment { ... public Object getByColumn(int columnIndex) { switch (columnIndex) { case 0: return date; case 1: return date; case 2: return sample; case 3: return sample; case 4: return history; case 5: return comment; } return null; } }

  • 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?

  • How to change input button image using CSS?

    - by Baltimark
    So, I can create an input button with an image using <INPUT type="image" src="/images/Btn.PNG" value=""> But, I can't get the same behavior using CSS. for instance, i've tried <INPUT type="image" class="myButton" value=""> where "myButton" is defined in the css file as .myButton{ background:url(/images/Btn.PNG) no-repeat; cursor:pointer; width: 200px; height: 100px; border: none; } If that's all I wanted to do, I could use the original style, but I want to change the button's appearance on hover (using a myButton:hover class). I know the links are good because I've been able to load them for a background image for other parts of the page (just as a check). I found examples on the web of how to do it using javascript, but I'm looking for a css solution. I'm using Firefox 3.0.3 if that makes a difference. Thanks

  • Log4j: Issues about the FallbackErrorHandler

    - by rdogpink
    I am working on a client-server-application and wanted to implement a flexible Loggingframework, so I chose log4j, which doesn´t really evolve anymore, but it is still handy framework. Because the Logging happens along the network, i wanted a solution for the case, that the network drive isn´t available, so the Logger has to change its destination file(s). Now I wanted to use the FallbackErrorHandler (configured with a XML-File) from the Log4j-library and the implementation worked: When my network drive isn´t available, it switches to a local Logfile, so no logging should be lost. But I headded two problems since yesterday and couldn´t figure or find out, how to solve it. No return to initial Logging Configuration: When the network drive is on again and the Logger could write to the old destinations, log4j still logs at the local drive and I can´t figure out, how to notify the original (primary) Logger to start again. I also tried to attach a second Appender to the ErrorHandler, which should mirror the failed primary Logger, that it tries to write on the network destination and when the network is on again, it logs in both files, on the local and on the network drive. But unfortunately it didn´t work out, I only got a failure message that the ErrorHandler-content doesn´t fit. log4j:WARN The content of element type "errorHandler" must match "(param*,root-ref?,logger-ref*,appender-ref?)". This is the responsible code. <appender name="TraceAppender" class="org.apache.log4j.DailyRollingFileAppender"> <!-- The second appender-ref "TestAppender" leads to the error. --> <errorHandler class="org.apache.log4j.varia.FallbackErrorHandler"> <logger-ref ref="com.idoh"/> <appender-ref ref="TraceFallbackAppender"/> <appender-ref ref="TestAppender"/> </errorHandler> <param name="datePattern" value=".yyyy-MM-dd" /> <param name="file" value="logs/Trace.txt" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-6r %d{HH:mm:ss,SSS} [%t] %-5p - %m%n"/> </layout> </appender> So, how could I trigger log4j to reset to initial configuration or hold a second appender parallel to the "Local-Logger". My Application should work by itself and shouldn´t have to be restarted often. First Error message is swallowed: I recognized, that the first message, which leads to the switching between the primary logger and the FallbackErrorHandler (for example a logging-request to a readonly-File), is swallowed, so neither the primary logger logs it (because it can´t) nor the backup-Logger knows what it missed. So anybody else ran in this problem and could solve it? Or has any suggestions?

  • Lambda expressions - set the value of one property in a collection of objects based on the value of

    - by Michael Rut
    I'm new to lambda expressions and looking to leverage the syntax to set the value of one property in a collection based on another value in a collection Typically I would do a loop: class item{ public string name {get;set;} public string value {get;set;} } class business { item item1 = new item(name="name1"); item item2 = new item(name="name2"); item item3 = new item(name="name3"); Collection<item> items = new Collection() {item1,item2,item3}; //This is what I want to simplify for( int i = 0; i < items.count; i++) { if(items[i].item.name == "name2") { //set the value items[i].item.value = "value2"; } } }

  • Type parameterization in Scala

    - by horatius83
    So I'm learning Scala at the moment, and I'm trying to create an abstract vector class with a vector-space of 3 (x,y,z coordinates). I'm trying to add two of these vectors together with the following code: package math class Vector3[T](ax:T,ay:T,az:T) { def x = ax def y = ay def z = az override def toString = "<"+x+", "+y+", "+z+">" def add(that: Vector3[T]) = new Vector3(x+that.x, y+that.y, z+that.z) } The problem is I keep getting this error: error: type mismatch; found : T required: String def add(that: Vector3[T]) = new Vector3(x+that.x, y+that.y, z+that.z) I've tried commenting out the "toString" method above, but that doesn't seem to have any effect. Can anyone tell me what I'm doing wrong?

  • Is it possible to use JavaScript to submit an unnamed form from outside an iFrame?

    - by Scott
    I know that may sound silly, but I'm trying to submit a form on a page inside an iFrame, from the parent site. Here's an example of the form: <form action="/add_email" method="post"> <div class="field"> <label for="newEmailAddress" style="width: auto">Add new email address</label> <input type="text" id="newEmailAddress" name="email" value="null" class="text-field" /> <input type="hidden" name="__app_key" value="null"/> <input type="submit" value="Add address and send activation email"> </div> </form> As you can see, the Submit button, and the form itself both lack a proper name or id, this is not something I have control over. (It's on an external website.) Any suggestions?

  • Haskell type classes and type families (cont'd)

    - by Giuseppe Maggiore
    I need some help in figuring a compiler error which is really driving me nuts... I have the following type class: infixl 7 --> class Selectable a s b where type Res a s b :: * (-->) :: (CNum n) => (Reference s a) -> (n,(a->b),(a->b->a)) -> Res a s b which I instance twice. First time goes like a charm: instance Selectable a s b where type Res a s b = Reference s b (-->) (Reference get set) (_,read,write) = (Reference (\s -> let (v,s') = get s in (read v,s')) (\s -> \x -> let (v,s') = get s v' = write v x (_,s'') = set s' v' in (x,s''))) since the type checker infers (-->) :: Reference s a -> (n,a->b,a->b->a) -> Reference s b and this signature matches with the class signature for (--) since Res a s b = Reference s b Now I add a second instance and everything breaks: instance (Recursive a, Rec a ~ reca) => Selectable a s (Method reca b c) where type Res a s (Method reca b c) = b -> Reference s c (-->) (Reference get set) (_,read,write) = \(x :: b) -> from_constant( Constant(\(s :: s)-> let (v,s') = get s :: (a,s) m = read v ry = m x :: Reference (reca) c (y,v') = getter ry (cons v) :: (c,reca) v'' = elim v' (_,s'') = set s' v'' in (y,s''))) :: Reference s c the compiler complains that Couldn't match expected type `Res a s (Method reca b c)' against inferred type `b -> Reference s c' The lambda expression `\ (x :: b) -> ...' has one argument, which does not match its type In the expression: \ (x :: b) -> from_constant (Constant (\ (s :: s) -> let ... in ...)) :: Reference s c In the definition of `-->': --> (Reference get set) (_, read, write) = \ (x :: b) -> from_constant (Constant (\ (s :: s) -> ...)) :: Reference s c reading carefully the compiler is telling me that it has inferred the type of (--) thusly: (-->) :: Reference s a -> (n,a->(Method reca b c),a->(Method reca b c)->a) -> (b -> Reference s c) which is correct since Res a s (Method reca b c) = b -> Reference s c but why can't it match the two definitions? Sorry for not offering a more succint and standalone example, but in this case I cannot figure how to do it...

  • Rails table inheritance issue

    - by Tristan O'Neil
    I've setup some models in the table inheritance fashion and everything seems to be all fine and dandy. But, when I use a collection select field to select values from one of the models it saves it but it saves the ID of the data and not the actual value of the data. So when I try to display the value on the show view it just shows the corresponding ID and not the actual value. Here is my setup. I'm using formtastic as a side note. View <%= show_field "County", @company.county %> Form <%= f.input :county, :label => 'County', :as => :select, :collection => County.find(:all) %> Base Model class Tag < ActiveRecord::Base before_create :set_type before_update :set_type attr_accessible :type, :name, :category belongs_to :company def set_type self.type = self.category end end Inherited Model class County < Tag end

  • explaining $this->load->view()

    - by ajsie
    in a controller you can use this method to load a view. but i want to know behind the scenes here. im new to php and frameworks, but i’ve learned the basics of OOP. when $this-view() is made then the method in the current class or the parent class is used. but what does this mean: $this-load-view(). what is the intermediate load? is it a function or is it a property? where is it located? how could it contain view()? grateful for explanation.

  • Constructing mocks in unit tests

    - by Flynn1179
    Is there any way to have a mock constructed instead of a real instance when testing code that calls a constructor? For example: public class ClassToTest { public void MethodToTest() { MyObject foo = new MyObject(); Console.WriteLine(foo.ToString()); } } In this example, I need to create a unit test that confirms that calling MethodToTest on an instance of ClassToTest will indeed output whatever the result of the ToString() method of a newly created instance of MyObject. I can't see a way of realistically testing the 'ClassToTest' class in isolation; testing this method would actually test the 'myObject.ToString()' method as well as the MethodToTest method.

  • ack misses results (vs. grep)

    - by techpeace
    I'm sure I'm misunderstanding something about ack's file/directory ignore defaults, but perhaps somebody could shed some light on this for me: mbuck$ grep logout -R app/views/ Binary file app/views/shared/._header.html.erb.bak.swp matches Binary file app/views/shared/._header.html.erb.swp matches app/views/shared/_header.html.erb.bak: <%= link_to logout_text, logout_path, { :title => logout_text, :class => 'login-menuitem' } %> mbuck$ ack logout app/views/ mbuck$ Whereas... mbuck$ ack -u logout app/views/ Binary file app/views/shared/._header.html.erb.bak.swp matches Binary file app/views/shared/._header.html.erb.swp matches app/views/shared/_header.html.erb.bak 98:<%= link_to logout_text, logout_path, { :title => logout_text, :class => 'login-menuitem' } %> Simply calling ack without options can't find the result within a .bak file, but calling with the --unrestricted option can find the result. As far as I can tell, though, ack does not ignore .bak files by default.

  • Dynamically render partial templates using mustache

    - by btakita
    Is there a way to dynamically inject partial templates (and have it work the same way in both Ruby & Javascript)? Basically, I'm trying to render different types of objects in a list. The best I can come up with is this: <div class="items"> {{#items}} <div class="item"> {{#is_message}} {{< message}} {{/is_message}} {{^is_message}} {{#is_picture}} {{< picture}} {{/is_picture}} {{^is_picture}} {{/is_picture}} {{/is_message}} </div> {{/items}} </div> For obvious reasons, I'm not super-psyched about this approach. Is there a better way? Also note that the different types of models for the views can have non-similar fields. I suppose I could always go to the lowest common denominator and have the data hash contain the html, however I would rather use the mustache templates.

  • Multiple operations depending on the type of the object passed

    - by mixm
    Assuming I create a method which is passed an object and that method would perform an action depending on the object passed. How should I identify the object? I thought of using the class name to identify the object, but that may be impractical since I could easily change the class name of objects, and generate headaches during future development. Am I right? edit: for example, i have objects ball and bomb. if i have another object called wall, and the wall has the method to resolve collisions with the wall (e.g. the coordinates of the colliding ball and bomb) but have different logic depending on the colliding object (i.e. ball and bomb)

  • Best approch to dynamically filter .net objects

    - by maxba
    The project i´m working currently on has a way to define a filter to filter objects from a database. This filter is a pretty straitforward class containing filtercriteria that will be combined to a sql where-clause. The goal now is to use this filter class to filter .net objects as well. So the filter for example defines, that the title property of the object that it is applied to must contain some userdefined string etc. What are ways to approch this problem? What should the filter return instead of the sql where-clause and how can it be applied to the object? I´m thinking about this for hours and don´t yet have even a slight idea how to solve this. Been thinking about reflection, dynamic code execution, building expressions but still haven´t found an acutal starting point.

  • Change right-click context menu options in VS2008

Now in my web app project, I'd like to be able to get the User Control listed in the right-click menu just like Component and Class, so I don't have to click New Item... then choose it from there. Is there a way to do this in the configuration? I can't seem to figure it out in VS.

  • PHP Type Hinting: array supported, object NOT?

    - by Marius Burz
    Am I missing something or there really is no support for generic object type hinting in PHP 5.x? I find it really strange that hinting arrays is supported while hinting objects is not, at least not out of the box. I'd like to have something like this: function foo(object $o) Just as we have: function foo(array $o) Example of possible use: methods of an objects collection class. Workaround: using an interface "Object" implemented by all classes or extending all classes from a generic class "Object" and writing something like this: function foo(Object $o) Well, that just ain't cute. Edit: somebody suggested in a deleted post using stdClass. It doesn't work: Catchable fatal error: Argument 1 passed to c::add() must be an instance of stdClass, instance of b given

  • JComobox is not showing in the JDialog
