  • jQuery not and classes

    - by Giles B
    Hi Guys, I have 2 anchor links (a.selector) and when one is clicked it has a class applied to it of 'active-arrow' and the click also removes the class of the same name from the other anchor as well as lowering the opacity to 0.2. I then want to have a fade effect when the user hovers over the anchor that doesn't have 'active-arrow' applied to it so that it goes to full opacity when mouseenters and back to 0.2 when mouseleaves. The problem im having is that both .not and :not don't seem to be working as expected, the hover effect works but if I click on the anchor whilst hovering the 'active-arrow' class is applied but when mouseleaves the opacity is faded down to 0.2 again even though the 'active-arrow' class is applied. Also the hover then doesn't work for the other a link which has had 'active-arrow' removed. Bit of a hard one to explain so heres some code that hopefully helps a bit. *//If a.selector doesn't have the class 'active-arrow' then run the hoverFade function* $("a.selector").not(".active-arrow").hoverFade(); //Functions for first element $('a.selector-1').click(function () { $('a.selector-2').removeClass('active-arrow'); //Remove background image from corresponding element $('ul#storage-items-2').fadeOut(1200).addClass('hide'); //Fade out then hide corresponding list $(this).addClass('active-arrow', 'fast'); //Add background image to current element $('ul#storage-items-1').removeClass('hide').fadeIn(1800); //Unhide and fade in the list $('a.selector-2').fadeTo(500, 0.2); //Fade corresponding element $(this).fadeTo(800, 1);//Fade this element to full opacity }); I only included the code for teh first anchor (a.selector-1) as the code for the second anchor is identical but just changes the class names to a.selector-2. Also the hoverFade function is in a seperate file so we can re-use it. jQuery.fn.hoverFade = function() { return this.each(function(){ $(this).hover( function () { $(this).fadeTo(500, 0.8); }, function () { $(this).fadeTo(500, 0.2); }); }); } Each anchor link fades in and fades out a UL as well. Any help is most appreciated Thanks Giles

  • My Android ListView item layout looks terrible

    - by jnylen
    I wanted to create a layout like the CyanogenMod call log in that there is a list item and a call button on the left which gets focus separately (screenshot). Instead, I get this mess. Here's my code: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:minHeight="?android:attr/listPreferredItemHeight" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingLeft="4dip" > <DontPressWithParentImageView android:id="@+id/play_icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:paddingLeft="14dip" android:paddingRight="14dip" android:layout_alignParentRight="true" android:gravity="center_vertical" android:src="@drawable/sym_play" android:background="@drawable/play_background" /> <View android:id="@+id/divider" android:layout_width="1px" android:layout_height="fill_parent" android:layout_marginTop="5dip" android:layout_marginBottom="5dip" android:layout_toLeftOf="@id/play_icon" android:layout_marginLeft="2dip" android:background="@drawable/divider_vertical_dark" /> <TextView android:id="@+id/file_info" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_marginBottom="8dip" android:layout_marginTop="-10dip" android:layout_marginLeft="10dip" android:layout_alignWithParentIfMissing="true" android:singleLine="true" android:ellipsize="marquee" android:textAppearance="?android:attr/textAppearanceSmall" android:textStyle="bold" /> <TextView android:id="@+id/file_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_above="@id/file_info" android:layout_alignWithParentIfMissing="true" android:layout_marginBottom="-10dip" android:layout_marginLeft="4dip" android:textAppearance="?android:attr/textAppearanceLarge" android:singleLine="true" android:ellipsize="marquee" android:gravity="center_vertical" /> </RelativeLayout> For reference, the code I started with is here and here, and the source to DontPressWithParentImageView is here (but as you can see from my screenshot, that part is working). What am I doing wrong?

  • Using ThreadPool.QueueUserWorkItem in ASP.NET in a high traffic scenario

    - by Michael Hart
    I've always been under the impression that using the ThreadPool for (let's say non-critical) short-lived background tasks was considered best practice, even in ASP.NET, but then I came across this article that seems to suggest otherwise - the argument being that you should leave the ThreadPool to deal with ASP.NET related requests. So here's how I've been doing small asynchronous tasks so far: ThreadPool.QueueUserWorkItem(s => PostLog(logEvent)) And the article is suggesting instead to create a thread explicitly, similar to: new Thread(() => PostLog(logEvent)){ IsBackground = true }.Start() The first method has the advantage of being managed and bounded, but there's the potential (if the article is correct) that the background tasks are then vying for threads with ASP.NET request-handlers. The second method frees up the ThreadPool, but at the cost of being unbounded and thus potentially using up too many resources. So my question is, is the advice in the article correct? If your site was getting so much traffic that your ThreadPool was getting full, then is it better to go out-of-band, or would a full ThreadPool imply that you're getting to the limit of your resources anyway, in which case you shouldn't be trying to start your own threads? Clarification: I'm just asking in the scope of small non-critical asynchronous tasks (eg, remote logging), not expensive work items that would require a separate process (in these cases I agree you'll need a more robust solution).

  • Alternating table row colors in freemarker

    - by itsadok
    What's a good, simple way to have alternate row coloring with freemarker? Is this really the best way? <#assign row=0> <#list items as item> <#if (row % 2) == 0> <#assign bgcolor="green"> <#else> <#assign bgcolor="red"> </#if> <tr style='background-color: ${bgcolor}'><td>${item}</td></tr> <#assign row = row + 1> </#list> I tried doing this: <#assign row=0> <#list items as item> <tr style='background-color: ${(row % 2) == 0 ? "green" : "blue"}'><td>${item}</td></tr> <#assign row = row + 1> </#list> But apparently you can't user the ternary operator in there. Note: I guess I should have mentioned it earlier, but I can't use css classes or javascript, since this HTML is going into an email message.

  • SDL doesn't detect Arrow Keys

    - by Scott
    I am working through the SDL tutorials over at http://lazyfoo.net/SDL_tutorials/index.php and I'm stuck on tutorial 8 where I'm working with key presses. I'm using the following code: //Our Main application loop while(!quit){ if(SDL_PollEvent(&curEvents)){ if(curEvents.type == SDL_QUIT){ quit = true; } //If a key was pressed if( curEvents.type == SDL_KEYDOWN ) { //Set the proper message surface switch( curEvents.key.keysym.sym ) { case SDLK_UP: message = upMessage; break; case SDLK_DOWN: message = downMessage; break; case SDLK_LEFT: message = leftMessage; break; case SDLK_RIGHT: message = rightMessage; break; default: message = TTF_RenderText_Solid(font, "Unknown Key", textColor); break; } } } if( message != NULL ) { //Apply the background to the screen applySurface( 0, 0, background, screen ); //Apply the message centered on the screen applySurface( ( SCREEN_WIDTH - message->w ) / 2, ( SCREEN_HEIGHT - message->h ) / 2, message, screen ); //Null the surface pointer message = NULL; } //Update the screen if( SDL_Flip( screen ) == -1 ) { return 1; } } Where works fine, the default case is reached, for everything BUT pressing the arrow keys. I was wondering if someone could spot what I'm doing wrong.

  • Best way to convert wpf triggers to silverlight?

    - by Stewart Armbrecht
    I have developed several custom controls in a wpf application that use triggers. what is the fastest way to convert the code so that I have a single code base that works both in the wpf application and the silverlight applicaiton. Here is a sample of the code: <Style x:Key="sButtonAction" TargetType="Button"> <!--<Setter Property="BitmapEffect" Value="{StaticResource BannerEffect}" />--> <Setter Property="Height" Value="25" /> <Setter Property="Margin" Value="4" /> <Setter Property="Cursor" Value="Hand" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Border x:Name="PART_Border" CornerRadius="10" BorderThickness="{StaticResource sBorderThicknessStandard}" BorderBrush="{StaticResource bColorBorder}" Background="{StaticResource ButtonActionBackground}"> <TextBlock x:Name="PART_TextBlock" Margin="5,2,5,2" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="White"> <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" /></TextBlock> </Border> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter TargetName="PART_TextBlock" Property="Foreground" Value="#990000"></Setter> </Trigger> <Trigger Property="IsPressed" Value="True"> <Setter TargetName="PART_Border" Property="Background" Value="{StaticResource ButtonActionBackgroundSelected}"></Setter> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style>

  • How to determine if a ResourceDictionary is loaded correctly

    - by akaphenom
    How can I tell (through the debugger if my app resources are being loaded correctly). I have tried (in f#) type MyApp() as this = inherit Application() do Application.LoadComponent(this, new System.Uri("/FSSilverlightApp;component/App.xaml", System.UriKind.Relative)) let cc = new ContentControl() let mainGrid : Grid = loadXaml("MainWindow.xaml") let siteTemplate : Grid = mainGrid let txt : TextBlock = siteTemplate ? txt do this.Startup.Add(this.startup) let mutable s = "Items: " s <- s + this.Resources.Count.ToString() it is returning a count of zero. Though I am pretty sure the application is loading the resource because if I change the path within the App.xaml - I get exceptions at runtime. Other re,lavent snippets are: I have the following app.xaml <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Module1.MyApp"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/FSSilverlightApp;component/TransitioningFrame.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> and content template: < ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ControlTemplate x:Key="TransitioningFrame" TargetType="navigation:Frame"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}"/> </Border> </ControlTemplate> </ResourceDictionary>

  • Stop all sounds permanently in AS3

    - by Fahim Akhter
    Hi, I have a main swf which has sound on/off buttons. It has many SWF's which are loaded into different placeholders at different time. All of them have different sounds in them. In addition to that there is a music loop going on in the background. Now, this perticular swf lets call it Father will be placed in some swf later on. What I'm trying to do right now is when the sound off button is pressed turn off all the sounds permanently so the child swf's and their sounds stop too. I have found a way in AS2 : global = new Sound( ) //no movie clip target path. and add the following code to your off button. on(release){ global.setVolume(0); //mutes all sound } and for on button on(release){ global.setVolume(100); //un mutes all sound } which ofcourse does not work for AS3. So how can I stop all sounds permanently in AS3? Secondly what if I have one sound (my background loop) which I want to keep going on. Would be a lot of help, been searching for a while now without a appropriate answer.

  • Scrollable list items in jQuery

    - by Giles B
    Hi Guys, I have a list of 4 items and the ul has a background image that makes the second item look as though it has an arrow behind it. I want to be able to scroll the items up or down when they are clicked to the second items position so for example when I click the fourth item the whole list scrolls up so the fourth item is then postioned over the top of the background image and all the other items will be sitting in the same order above it. I have tried using jQuery Tools with the circular option selected but it clones the first an last item and i end up with a gap when i get to the bottom and I also cant make each item selectable to scroll the list up or down. Here is the code for the list <div id="priceGuide"> <ul id="priceRegion"> <li><a href="#">North & Midlands</a></li> <li><a href="#">London, north of the river</a></li> <li><a href="#">London, south of the river</a></li> <li><a href="#">South & South East</a></li> </ul><!-- /priceRegion --> </div><!-- /priceGuide --> Any help is most appreciated. Thanks Giles

  • Integrating a Custom Compiler with the Visual Studio IDE

    - by M.A. Hanin
    Background: I want to create a custom VB compiler, extending the "original" compiler, to handle my custom compile-time attributes. Question: after I've created my custom compiler and I've got an executable file capable of compiling VB code via the standard command-line interface, how do I integrate this compiler with the Visual Studio IDE? (such that pressing "compile" or "build" will make use of my compiler instead of the default compiler). EDIT: (Correct me if i'm wrong) From the reactions here, I see this question is a bit shocking, so I shall further explain my needs and background: .NET provides us with a great mechanism called Attributes. As far as I understand, making attributes apply their intended behavior upon the attributed element (assembly, module, class, method, etc.) - attributes must be reflected upon. So the real trick here is reflecting and applying behavior at the right spot. Lets take Serialization for example: We decorate a class with the Serializable attribute. We then pass an instance of the class to the formatter's Serialize method. The formatter reflects upon the instance, checking if it has the Serializable attribute, and acting accordingly. Now, if we examine the Synchronization, Flags, Obsolete and CLSCompliant attributes, then the real question is: who reflects upon them? At least in some cases, it has to be the compiler (and/or IDE). Therefore, it seems that if I wish to create custom attributes that change an element's behavior regardless of any specific consumer, i must extend the compiler to reflect upon them at compilation. Of course, these are not my personal insights: the book "Applied .NET Attributes" provides a complete example of creating a custom attribute and a custom C# compiler to reflect upon that attribute at compilation (the example is used to implement "java-style checked exceptions").

  • How important is managing memory in Objective-C?

    - by Alex Mcp
    Background: I'm (jumping on the bandwagon and) starting learning about iPhone/iPad development and Objective-C. I have a great background in web development and most of my programming is done in javascript (no libraries), Ruby, and PHP. Question: I'm learning about allocating and releasing memory in Objective-C, and I see it as quite a tricky task to layer on top of actually getting the farking thing to run. I'm trying to get a sense of applications that are out there and what will happen with a poorly memory-managed program. A) Are apps usually released with no memory leaks? Is this a feasible goal, or do people more realistically just excise the worst offenders and that's ok? B) If I make an NSString for a title of a view, let's say, and forget to deallocate it it, does this really only become a problem if I recreate that string repeatedly? I imagine what I'm doing is creating an overhead of the memory needed to store that string, so it's probably quite piddling (a few bytes?) However if I have a rapidly looping cycle in a game that 'leaks' an int every cycle or something, that would overflow the app quite quickly. Are these assumptions correct? Sorry if this isn't up the community-wiki alley, I'm just trying to get a handle on how to think about memory and how careful I'll need to be. Any anecdotes or App Store-submitted app experiences would be awesome to hear as well.

  • Can push technology / comet be faked?

    - by stef
    Client has a dating site and would like to have a popup (either a nice javascript overlay or a new browser window popup. we're flexible.) displayed to users when another user is visiting their page. I'm familiar with push technology and Comet but it's quite challenging to implement this and may place serious strain on a server with over 100,000 unique visitors per day. I'm wondering if there is a way of faking this, perhaps by not being accurate to the second. I can't really think of any way. This is a classic LAMP environment. Anyone? EDIT: what about this: placing an iframe on the page that refreshes every few seconds and at each page load it checks in the db if a visitor has been logged on this profile page. if so, it shows a message. the message would be visible but the background of the iframe would blend in with the background of the site and be invisible. if the message fades in and out, it would look like a JS box "popping up".

  • Automatically support new changes with Python.

    - by Zachary Brown
    I was working on a program,that I need to support new additions. Hmmm. Let me give you some background on the program. It is an educational software program that has quizzes for the user to take, just to gain odd knowledge. Now, It currently supports 6 subjects, all organized with directores on the HDD ( i.e. the Science directory is called science. ) and the way you launch the subject to see what quizzes you have to take is by pushing a button on the home screen. This sort of thing prevents easy subject additions. I want to be able to add a subject later on without having to recode the home screen and re organize all the buttons. I would use a Listbox and os.listdir(...), but I was kind of wanting something prettier than a Listbox. I am using Tkinter on Windows. The Python version I am using is 2.6 Is there a "fancy" listbox sort of thing that can be styled to work with the background?

  • Strategies for Accessing a Application with a COM API From PHP

    - by Alan Storm
    Background: Experienced PHP developer with a mostly *nix background. I'm writing a PHP application that needs to interact with a proprietary 3rd party system. The 3rd party system is Windows only. The PHP application will be living on a separate Linux based system The 3rd party application has been described as having a "COM API" that I'll need to talk to from the PHP application. What does this look like architecturally speaking? I'm starting with the COM section of the PHP manual, but I have specific questions. Specific Questions: Can I talk directly to a COM API from a PHP application running on another server? If so, how? (what PHP extensions would I need, or what protocols/PHP functions would I be using to talk to the API) If the answer to number 2 is no, I'd assume I'd need some kind of application on the Windows machine that can talk to COM, and then a service on the windows machine I can hit with PHP. Are there prebuilt frameworks for this kind of thing? Is this all nonsense and/or did I say something exceedingly stupid? (Quite possible, as I'm a little fuzzy on what "COM" does and doesn't cover) I'm obviously not looking for a full solution here, I'm just trying to get a general idea of what is and isn't possible and what kind of things I'll want to Google for. Thanks!

  • WPF ComboBox TemplateBinding to selected value

    - by Greg R
    I'm trying to create an editable textbox via a drop down of selected values. Basically in Red Only mode I want the drop down to be a disabled textbox. It works fine when I do this with SelectedValue but when I need it to display the dropdown text and not the value. This is what I have: <Style x:Key="EditableDropDownValueOnly" TargetType="ComboBox"> <Setter Property="Width" Value="Auto" /> <Setter Property="FontSize" Value="11" /> <Setter Property="HorizontalAlignment" Value="Left" /> <Setter Property="FontFamily" Value="Verdana" /> <Setter Property="MinWidth" Value="25" /> <Style.Triggers> <Trigger Property="IsReadOnly" Value="True"> <Setter Property="Background" Value="#FFFFFF" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ComboBox"> <TextBox Text="{TemplateBinding SelectedItem, Converter={StaticResource StringCaseConverter}}" BorderThickness="0" Background="Transparent" FontSize="{TemplateBinding FontSize}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" FontFamily="{TemplateBinding FontFamily}" Width="{TemplateBinding Width}" TextWrapping="Wrap"/> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> SelectedItem is a KeyValuePair, since my drop down is bound to a dictionary. I'm trying to display the "Value" element in my template. Is that possible? Thanks a lot!

  • Blurry UILabel as programmatic subview of UITableViewCell contentView

    - by Alex Reynolds
    I am adding a UILabel instance as a subview of my custom UITableViewCell instance's contentView. When I select the cell, the row is highlighted blue, except for the background of the label. The label text is sharp. When I set the label and content view backgroundColor property to [UIColor clearColor], the label text becomes blurry. How do I set the label background color to be clear, to allow the row highlight to come through, while still keeping the label text sharp? One suggestion I read elsewhere was to round the label's frame values, but this did not have any effect. CODE Here is a snippet of my custom UITableViewCell subview's -setNeedsLayout method: UILabel *_objectTitleLabel = [[UILabel alloc] initWithFrame:CGRectNull]; _objectTitleLabel.text = [self.awsObject cleanedKey]; _objectTitleLabel.font = [UIAppDelegate defaultObjectLabelFont]; _objectTitleLabel.highlightedTextColor = [UIColor clearColor]; //[UIAppDelegate defaultLabelShadowTint]; _objectTitleLabel.backgroundColor = [UIColor clearColor]; //[UIAppDelegate defaultWidgetBackgroundTint]; _objectTitleLabel.frame = CGRectMake( kCellImageViewWidth + 2.0 * self.indentationWidth, 0.5 * (self.tableView.rowHeight - 1.5 * kCellLabelHeight) + kCellTitleYPositionNudge, contentViewWidth, kCellLabelHeight ); _objectTitleLabel.frame = CGRectIntegral(_objectTitleLabel.frame); _objectTitleLabel.tag = kObjectTableViewCellTitleSubviewType; //NSLog(@"_objectTitleLabel: %@", NSStringFromCGRect(_objectTitleLabel.frame)); [self.contentView addSubview:_objectTitleLabel]; [_objectTitleLabel release], _objectTitleLabel = nil; ... self.contentView.backgroundColor = [UIAppDelegate defaultWidgetBackgroundTint]; self.contentView.clearsContextBeforeDrawing = YES; self.contentView.autoresizesSubviews = YES; self.contentView.clipsToBounds = YES; self.contentView.contentMode = UIViewContentModeRedraw;

  • Trigger for ComboBox in Silverlight

    - by Budda
    Is there any possibility to display selected item of the ComboBox (after popup closing) in a way that is different from its displaying in DropDown List (There are players number and name in the dropdown list, but after list closing I want to see only its number). How can I change a background for the player with some Flag? As far as I know, all of that can be done with triggers, but are they supported in Silverlight 4, VS2010, Silverlight Toolkit 4? In my case the following code <ComboBox ItemsSource="{Binding PlayersAll}" SelectedItem="{Binding Path=SelectedPlayer, Mode=TwoWay}" > <ComboBox.ItemTemplate> <DataTemplate> <ToolkitControls:WrapPanel Orientation="Horizontal"> <TextBlock Text="{Binding TeamNumber}"/> <TextBlock Text=" - "/> <TextBlock Text="{Binding ShortName}"/> </ToolkitControls:WrapPanel> <DataTemplate.Triggers> <Trigger Property="HasError" Value="True"> <Setter Property="Background" TargetName="FlagSet" Value="Red"/> </Trigger> </DataTemplate.Triggers> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> gives an error: The property 'Triggers' does not exist on the type 'DataTemplate' in the XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation' what is wrong here?

  • Single-player pong game

    - by jcovert
    Hi, I'm trying to fadeIn and fadeOut a transparent png using JQuery. Of course, it looks slick in Firefox, but significantly less than acceptable in IE (7 and 8). It's a known bug with IE, and unfortunately there doesn't seem to be much of a workaround. Basically what I'm doing is place a semi-transparent white rectangle over an image to make the image appear 'in the background'. I want to do this smoothly, and that's where fadeIn comes in. Because of the IE bug, however, I've been forced to fadeIn a completely opaque white rectangle over the image instead, making it unfortunately disappear. While this looks significantly better and is ALMOST what I'm looking for, it's still not acceptable. The user needs to be able to see SOME image on the page, albeit in the background. So my question is this: Is there a way to stop the fadeIn function (or any jquery animation, really) after animating for 75% of its expected animation time? This would leave my image 75% mixed the white rectangle, and I wouldn't have to deal with IE's nasty transparent png bug. Thanks!

  • Finding string in php

    - by Roshan
    I have a content and i want to search a keyword in that content. Content When charting multiple data series, or just to improve the appearance of your charts, you can control the fill for each series in the chart or each item in a series. The fill lets you specify a pattern that defines how Flex draws the chart element. You also use fills to specify the background colors of the chart or bands of background colors defined by the grid lines. Fills can be solid or can use linear and radial gradients. A gradient specifies a gradual color transition in the fill color therefore. NOw, if the keyword we are searching is "When", it is the starting word so should display as "When charting multiple data ..........." If the keyword is "draws" , it lies in middle so should be displayed as ".... how Flex draws....." If the kewyword is "therefore", it is in the last position so should be displayed as ".........transition in the fill color therefore." Can anyone help me out how to do this in php server script?

  • Want to learn Objective-C but syntax is very confusing

    - by Sahat
    Coming from Java background I am guessing this is expected. I would really love to learn Objective-C and start developing Mac apps, but the syntax is just killing me. For example: -(void) setNumerator: (int) n { numerator = n; } What is that dash for and why is followed by void in parenthesis? I've never seen void in parenthesis in C/C++, Java or C#. Why don't we have a semicolon after (int) n? But we do have it here: -(void) setNumerator: (int) n; And what's with this alloc, init, release process? myFraction = [Fraction alloc]; myFraction = [myFraction init]; [myFraction release]; And why is it [myFraction release]; and not myFraction = [myFraction release]; ? And lastly what's with the @ signs and what's this implementation equivalent in Java? @implementation Fraction @end I am currently reading Programming in Objective C 2.0 and it's just so frustrating learning this new syntax for someone in Java background.

  • Using a CALayer in UITableViewCell

    - by Brian
    On each cell of my table view I want to have a bar that the user can slide out from the right. On the bar I plan to have icons. So, to do this I subclassed UITableViewCell. On the cell I have implemented drawRect and in there I have already drawn a gradient and background color on the cell. From there, I can create a CALayer, give it a frame & background color, and add it as a sub layer to the Views subLayers array. I can do all that and it will display my layer on each UITableViewCell. I have added touch events to the cell so I can detect when the user touches the cell and for testing I have made it so when the user swipes, my CALayer gets wider. But the issue is, when the UITableView scrolls and reuses a cell whose CALayer has been widened, it doesn't recreate the CALayer. I have tried [myLayer setNeedsDisplay] and used the drawLayer:inContext method of its delegate and it doesn't get called. I have also tried telling call setNeedsDisplay on the cell in my UITableViewController hoping that that will cause a redraw, but it doesn't work. I'm not sure what I'm missing. I am new to CoreGraphics & CoreAnimation. I have read through the CoreAnimation Developers Guide, but I'm assuming I missing something. Any help would be great.
