• Flex, can't custom style the tooltip

  - by touB

  I'm having trouble changing the font size of my TextInput tooltip. The text input looks like this: <s:TextInput id="first" toolTip="Hello"/> then I create a style like this: <fx:Style> @namespace s "library://ns.adobe.com/flex/spark"; @namespace mx "library://ns.adobe.com/flex/halo"; mx|ToolTip { fontSize: 24; } </fx:Style> but absolutely nothing happens. Any idea what I may be doing wrong?

• Animated record deletion with jquery like mootools example

  - by twitter

  I was reading around and saw this example from David Walsh about how to animate record deletion with mootools. Does the exact same effect exist in jquery? This is his mootools code. window.addEvent('domready',function() { $$('a.delete').each(function(el) { el.addEvent('click',function(e) { e.stop(); var parent = el.getParent('div'); var request = new Request({ url: 'mootools-record-delete.php', link: 'chain', method: 'get', data: { 'delete': parent.get('id').replace('record-',''), ajax: 1 }, onRequest: function() { new Fx.Tween(parent,{ duration:300 }).start('background-color', '#fb6c6c'); }, onSuccess: function() { new Fx.Slide(parent,{ duration:300, onComplete: function() { parent.dispose(); } }).slideOut(); } }).send(); }); }); });

• Using Python read specific (column, row) values from a txt file

  - by user2955708

  I would like to read values from a text file until that is a float value. Lets say I have the following file: 14:53:55 Load 300 Speed 200 Distance,m Fz Fx Speed 0.0000 249 4 6.22 0.0002 247 33 16.29 0.0004 246 49 21.02 0.2492 240 115 26.97 0.2494 241 112 21.78 0.2496 240 109 13.09 0.2498 169 79 0.27 Distance,m Fz Fx Speed 0.0000 249 4 7.22 0.0002 247 33 1.29 0.0004 246 49 271.02 0.2492 240 115 26.97 0.2494 241 112 215.78 0.2496 240 109 13.09 0.2498 169 79 0.27 And I need only the values under the first Distance column. So something like skip the first few rows, then read values from the first column while it is float. Thanks your help in advance

• How do you detect an area that can be filled in in a bitmap in ActionScript 3?

  - by 1.21 gigawatts

  I am having a tough time figuring this out. I need to be able to detect a fill area for something similar to a coloring book picture. The user will click inside the area that needs to be filled. The image is user created bitmap content and so the fill area must be detected at runtime. Any help would be tremendously appreciated! Posting Flex 4 code for review: <fx:Script> <![CDATA[ protected function myImage_clickHandler(event:MouseEvent):void { myImage.imageDisplay.bitmapData.floodFill(event.localX,event.localY,0xFFFFFF); } ]]> </fx:Script> <s:Image id="myImage" click="myImage_clickHandler(event)" source="/images/square.gif"/>

  In my application this works: <s:VGroup width="100%" paddingLeft="100"> ... stuff ... </s:VGroup> This doesn't: <fx:Style> @namespace s "library://ns.adobe.com/flex/spark"; @namespace mx "library://ns.adobe.com/flex/mx"; .myStyle { paddingLeft: 100; } </fx:Style> <s:VGroup width="100%" styleName="myStyle"> ... stuff ... </s:VGroup> Why not?

• Jerome has written a nice article on integrating SceneBuilder with several IDEs

  - by daniel

  My colleague Jerome Cambon has written a very nice article about how to get SceneBuilder working with several IDEs. The JavaFX SceneBuilder is at the root a stand-alone tool - but there are various tweaks and tricks that you can use to make its use in conjunction with your favorite IDE a more enjoyable experience. In his article - Jerome shows how this can be done with NetBeans (7.3), Eclipse, with Tom's excellent e(fx)clipse plugin, and IntelliJ IDEA. Good work Jerome!

  var bytecode = ShaderBytecode.CompileFromFile("shaders\\testShader.fx", "fx_5_0", ShaderFlags.None, SlimDX.D3DCompiler.EffectFlags.None, null, null, out str); var effect = new SlimDX.Direct3D11.Effect(gpu.Device, bytecode); Works fine but if I try to use another shader model like 4.0 or 3.0 it throws an error on the new effect creation: E_FAIL: An undetermined error occurred (-2147467259) How do I compile older shaders? And I've read about device context but I can't find any information on how to use them to maintain DX9 compatibility.

• Attaching a Command to the WP7 Application Bar.

  - by mbcrump

  One of the biggest problems that I’ve seen with people creating WP7 applications is how do you bind the application bar to a Relay Command. If your using MVVM then this is particular important. Let’s examine the code that one might add to start with.  <phone:PhoneApplicationPage.ApplicationBar> <shell:ApplicationBar IsVisible="True" IsMenuEnabled="True"> <shell:ApplicationBarIconButton x:Name="appbar_button1" IconUri="/icons/appbar.questionmark.rest.png" Text="About"> <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <GalaSoft_MvvmLight_Command:EventToCommand Command="{Binding DisplayAbout, Mode=OneWay}" /> </i:EventTrigger> </i:Interaction.Triggers> </shell:ApplicationBarIconButton> <shell:ApplicationBar.MenuItems> <shell:ApplicationBarMenuItem x:Name="menuItem1" Text="MenuItem 1"></shell:ApplicationBarMenuItem> <shell:ApplicationBarMenuItem x:Name="menuItem2" Text="MenuItem 2"></shell:ApplicationBarMenuItem> </shell:ApplicationBar.MenuItems> </shell:ApplicationBar> </phone:PhoneApplicationPage.ApplicationBar> Everything looks right. But we quickly notice that we have a squiggly line under our Interaction.Triggers. The problem is that the object is not a FrameworkObject. This same code would have worked perfect if this were a normal button. OK. Point has been proved. Let’s make the ApplicationBar support Commands. So, go ahead and create a new project using MVVM Light. If you want to check out the source and work along side this tutorial then click here.  7 Easy Steps to have binding on the Application Bar using MVVM Light (I might add that you don’t have to use MVVM Light to get this functionality, I just prefer it.) 1) Download MVVM Light if you don’t already have it and install the project templates. It is available at http://mvvmlight.codeplex.com/. 2) Click File-New Project and navigate to Silverlight for Windows Phone. Make sure you use the MVVM Light (WP7) Template. 3) Now that we have our project setup and ready to go let’s download a wrapper created by Nicolas Humann here, it is called Phone7.Fx. After you download it then extract it somewhere that you can find it. This wrapper will make our application bar/menu item bindable. 4) Right click References inside your WP7 project and add the .dll file to your project. 5) In your MainPage.xaml you will need to add the proper namespace to it. Don’t forget to build your project afterwards. xmlns:Preview="clr-namespace:Phone7.Fx.Preview;assembly=Phone7.Fx.Preview" 6) Now you can add the BindableAppBar to your MainPage.xaml with a few lines of code.  <Preview:BindableApplicationBar x:Name="AppBar" BarOpacity="1.0" > <Preview:BindableApplicationBarIconButton Command="{Binding DisplayAbout}" IconUri="/icons/appbar.questionmark.rest.png" Text="About" /> <Preview:BindableApplicationBar.MenuItems> <Preview:BindableApplicationBarMenuItem Text="Settings" Command="{Binding InputBox}" /> </Preview:BindableApplicationBar.MenuItems> </Preview:BindableApplicationBar> So your final MainPage.xaml will look similar to this: NOTE: The AppBar will be located inside of the Grid using this wrapper.   <!--LayoutRoot contains the root grid where all other page content is placed--> <Grid x:Name="LayoutRoot" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <!--TitlePanel contains the name of the application and page title--> <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="24,24,0,12"> <TextBlock x:Name="ApplicationTitle" Text="{Binding ApplicationTitle}" Style="{StaticResource PhoneTextNormalStyle}" /> <TextBlock x:Name="PageTitle" Text="{Binding PageName}" Margin="-3,-8,0,0" Style="{StaticResource PhoneTextTitle1Style}" /> </StackPanel> <!--ContentPanel - place additional content here--> <Grid x:Name="ContentGrid" Grid.Row="1"> <TextBlock Text="{Binding Welcome}" Style="{StaticResource PhoneTextNormalStyle}" HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="40" /> </Grid> <Preview:BindableApplicationBar x:Name="AppBar" BarOpacity="1.0" > <Preview:BindableApplicationBarIconButton Command="{Binding DisplayAbout}" IconUri="/icons/appbar.questionmark.rest.png" Text="About" /> <Preview:BindableApplicationBar.MenuItems> <Preview:BindableApplicationBarMenuItem Text="Settings" Command="{Binding InputBox}" /> </Preview:BindableApplicationBar.MenuItems> </Preview:BindableApplicationBar> </Grid> 7) Let’s go ahead and create the RelayCommands and write them up to a MessageBox by editing our MainViewModel.cs file. public class MainViewModel : ViewModelBase { public string ApplicationTitle { get { return "MVVM LIGHT"; } } public string PageName { get { return "My page:"; } } public string Welcome { get { return "Welcome to MVVM Light"; } } public RelayCommand DisplayAbout { get; private set; } public RelayCommand InputBox { get; private set; } /// <summary> /// Initializes a new instance of the MainViewModel class. /// </summary> public MainViewModel() { if (IsInDesignMode) { // Code runs in Blend --> create design time data. } else { DisplayAbout = new RelayCommand(() => { MessageBox.Show("About box called!"); }); InputBox = new RelayCommand(() => { MessageBox.Show("settings button called"); }); } } If you run the project now you should get something similar to this (notice the AppBar at the bottom):  Now if you hit the question mark then you will get the following MessageBox: The MenuItem works as well so for Settings: As you can see, its pretty easy to add a Command to the ApplicationBar/MenuItem.

• Looking into the JQuery Cycle Plugin

  - by nikolaosk

  I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client. You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery Cycle Plugin.I have been using extensively this plugin in my websites.You can rotate a series of images using various transitions with this plugin.It is a slideshow type of experience. I will be writing more posts regarding the most commonly used JQuery Plugins.  In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here.  You can download this plugin from this link I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5) <!DOCTYPE html><html lang="en">  <head>    <title>Liverpool Legends</title>        <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >            <script type="text/javascript" src="jquery-1.8.3.min.js"> </script>     <script type="text/javascript" src="jquery.cycle.all.js"></script>              <script type="text/javascript">        $(function() {            $('#main').cycle({ fx: 'fade'});        });    </script>       </head>  <body>    <header>        <h1>Liverpool Legends</h1>    </header>        <div id="main">                   <img src="championsofeurope.jpg" alt="Champions of Europe">                        <img src="steven_gerrard.jpg" alt="Steven Gerrard">                        <img src="ynwa.jpg" alt="You will never walk alone">                       </div>            <footer>        <p>All Rights Reserved</p>      </footer>     </body>  </html> This is a very simple markup. I have added three photos (make sure you use your own when trying this example)I have added references to the JQuery library (current version is 1.8.3) and the JQuery Cycle Plugin. Then I have added 3 images in the main div element.The Javascript code that makes it all happen follows.  <script type="text/javascript">        $(function() {            $('#main').cycle({ fx: 'fade'});        });    </script>  It couldn't be any simpler than that. I view my simple in Internet Explorer 10 and it works as expected. I have this series of images transitioning one after the other using the "fade" effect. I have tested this simple solution in all major browsers and it works fine.We can have a different transition effect by changing the JS code. Have a look at the code below       <script type="text/javascript">        $(function() {            $('#main').cycle({                     fx: 'cover',        speed: 500,        timeout: 2000                        });        });    </script>   We set the speed to 500 milliseconds, that is the speed we want to have for the ‘cover’ transition.The timeout is set to two seconds which is the time the photo will show until the next transition will take place.We can customise this plugin further but this is a short introduction to the plugin.Hope it helps!!!

• Byobu not displaying correct CPU temptrature

  - by aserwin

  I have an AMD FX 8120 proccy that is overclocked to 4100Mhz. Since the overclocking, Byobu and other temprature reading apps (Conky, etc) do not read the temprature accurately. I can see the correct temp in the bios, and with no overclocking everything inside of Gnome reads correctly. Why should this be? It is (seemingly) obviously an issue with Ubuntu (or perhaps Gnome?). Has anyone else experienced this?

• How to generate portal zones?

  - by Meow

  I'm developing a portal-based scene manager. Basically all it does is to check the portals against the camera frustum, and render their associated portal zones accordingly. Is there any way my editor can generate portal zones automatically with the user having to set the portals themselves only? For example, the Max Payne 1/2 engine ("Max-FX") only required to set the portal quads, unlike the C4 engine where you also have to explicitly set the portal zones.

• Is there a driver like this for Windows XP too?

  - by ptikobj

  In Ubuntu, there is a modified non-proprietary Nvidia driver preinstalled. This driver helps me get the full native resolution (1920x1020) of my flatscreen displayed without errors, while my Graphics Card (Geforce FX 5200) only supports DVI-resolutions up to 1440x900. This is a very cool thing. My question is: Is there such a kind of driver also for Windows XP? I've already tried the omega drivers, but 1920x1020 looks awful on Windows.

• Notes - Part I - Say Hello from Java

  - by Silviu Turuga

  Sometimes we need to take small notes to remember things, one way to do this is to use stick notes and have them all around our desktop. But what happening if you have a lot of notes and a small office? You'll need a piece of software that will sort things for you and also it will provide you a quick way to retrieve the notes when need. Did I mention that this will keep your desktop clean and also will reduce paper waste? During the next days we'll gonna create an application that will let you manage your notes, put them in different categories etc. I'll show you step by step what do you need to do and finally you'll have the application run on multiple systems, such as Mac, Windows, Linux, etc. The only pre-requisition for this lesson is to have JDK 7 with JavaFX installed and an IDE, preferably NetBeans. I'll call this application Notes…. Part I - Say Hello from Java  From NetBeans go to Files->New Project Chose JavaFX->JavaFX FXML Application Project Name: Notes FXML name: NotesUI Check Create Application Class and name it Main After this the project is created and you'll see the following structure As a best practice I advice you to have your code in your own package instead of the default one. right click on Source Packages and chose New->Java Package name it something like this: com.turuga.notes and click Next after the package is created, select all the 3 files from step #3 and drag them over the new package chose Refactor, as this will make sure all the references are correctly moved inside the new package now you should have the following structure if you'll try to run the project you'll get an error: Unable to find class: Main right click on project name Notes and click properties go to Run and you'll see Application Class set to Main, but because we have defined our own packages, this location has been change, so click on Browse and the correct one appear: com.turuga.notes.Main last modification before running the project is to right click on NotesUI.fxml and chose Edit (if you'll double click it will open in JavaFX Scene Builder) look around line 9 and change fx:controller="NotesUIController" to fx:controller="com.turuga.notes.NotesUIController" now you are ready to run it and you should see the following On the next lesson we'll continue to play with NetBeans and start working on the interface of our project
