  • App will not launch from drawer after phone is removed from car dock

    - by BigFwoosh
    I am creating a replacement Car Home app for Android 2.0+ devices. The app needs to launch when the phone is inserted into the car dock, as well as terminate when it is removed from the dock. It also needs to be able to be launched from the app drawer. I'm having a problem right now where once the phone is inserted and removed from the dock, I can no longer launch the app from the app drawer because every time I launch the app my BroadcastReceiver picks up a DOCK_EVENT action for some reason. I created a test project that only registers my BroadcastReceiver, and the same thing happens. Here's the code for the BroadcastReceiver: public class CarDockBroadcastReceiver extends BroadcastReceiver { /** * @see android.content.BroadcastReceiver#onReceive(Context,Intent) */ @Override public void onReceive(Context context, Intent intent) { // TODO Put your code here if(intent.getExtras().containsKey("android.intent.extra.DOCK_STATE")){ int state = intent.getExtras().getInt("android.intent.extra.DOCK_STATE",1); if(state == 0){ Log.i("Dock", "Removed from dock!"); ((Activity)context).finish(); } } } } My main Activity is as follows: public class MainActivity extends Activity { /** Called when the activity is first created. */ CarDockBroadcastReceiver receiver; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); IntentFilter filter = new IntentFilter("android.intent.action.DOCK_EVENT"); receiver = new CarDockBroadcastReceiver(); registerReceiver(receiver, filter); } @Override protected void onDestroy() { // TODO Auto-generated method stub unregisterReceiver(receiver); super.onDestroy(); } } The main Activity has an intent filter for action.MAIN, category.LAUNCHER, category.DEFAULT, and category.CAR_DOCK. Any ideas on why this is happening?

  • I need a true mouseOver...

    - by invertedSpear
    Ok, so mouseOver and RollOver, and their respective outs work great as long as your mouse is actually over the item, or one of it's children. My problem is that I may have another UI component "between" my mouse and the item I want to process the mouse/rollover(maybe a button that is on top of a canvas, but is not a child of the canvas). The mouse is still over the component, there's just something else that it's over at the same time. Any tips or help how to deal with this? Let me know if I'm not being clear enough. Here is a simplified code example detailing my question copy/paste that into your flex/flash builder and you'll see what I mean: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="500" height="226" creationComplete="ccInit()"> <mx:Script> <![CDATA[ private function ccInit():void{ myCanv.addEventListener(MouseEvent.ROLL_OVER,handleRollOver); } private function handleRollOver(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",1); myCanv.addEventListener(MouseEvent.ROLL_OUT,handleRollOut); } private function handleRollOut(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",0); myCanv.removeEventListener(MouseEvent.ROLL_OUT,handleRollOut); } ]]> </mx:Script> <mx:Canvas id="myCanv" x="10" y="10" width="480" height="200" borderStyle="solid" borderColor="#000000" backgroundColor="#FFFFFF" backgroundAlpha="0"> </mx:Canvas> <mx:Button x="90" y="50" label="Button" width="327" height="100"/> </mx:Application>

  • Sencha touch 2/ app workflow with navigation view

    - by eplatonov
    I am trying to understand how can I implement the same functionality which provides navigation view in sencha touch 2, but .... Each item of the 'Ext.NavigationView' component should have it's own unique set of 'navigationBar' elements. I mean set of buttons, for example. I know that I can do something like this: this.getMain().getNavigationBar().rightBox.removeAll(); this.getMain().getNavigationBar().rightBox.add(this.getSettingButton()); //where 'getSettingButton' predefined by me a button And do this action each time when 'push' event happens (clear 'navigationBar' and add appropriate set of buttons) Of course, I even can implement 'Ext.Panel' with 'layout: card' and set of 'Ext.panel' elements in the 'items' property, each of which will be have unique 'toolbar'. To control the behavior I can use 'setActiveItem' method. But, I think each of these approaches is a bit weird, isn't it? I expected that would be much more natural approach to implement it. Most likely I don't know what I need. Confirm my doubts. What is the best way to do it.

  • jquery child selector problems

    - by codedude
    I have a basic website nav layout that looks like this: <li class="folder parent_folder"> <a href="#">Some Folder</a> <ul class="submenu"> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> </ul> I have several of these throughout the site's page. Using jquery, I'm trying to make it so that when you click "li.parent_folder" "ul.submenu" disappears and then reappears when you click "li.parent_folder" again. I can get it to do this but I have a problem. When I click on the "li.parent_folder" all the "ul.submenu" disapear instead of just the one that is the child of it. What would be the correct jquery code to accomplish this? (Oh, I'm using jquery ui also in this project What I have right now is this: $('li.parent_folder').click(function() { $('li.parent_folder ul.submenu').hide(); });

  • DataGrid: dynamic DataTemplate for dynamic DataGridTemplateColumn

    - by Lukas Cenovsky
    I want to show data in a datagrid where the data is a collection of public class Thing { public string Foo { get; set; } public string Bar { get; set; } public List<Candidate> Candidates { get; set; } } public class Candidate { public string FirstName { get; set; } public string LastName { get; set; } ... } where the number of candidates in Candidates list varies at runtime. Desired grid layout looks like this Foo | Bar | Candidate 1 | Candidate 2 | ... | Candidate N I'd like to have a DataTemplate for each Candidate as I plan changing it during runtime - user can choose what info about candidate is displayed in different columns (candidate is just an example, I have different object). That means I also want to change the column templates in runtime although this can be achieved by one big template and collapsing its parts. I know about two ways how to achieve my goals (both quite similar): Use AutoGeneratingColumn event and create Candidates columns Add Columns manually In both cases I need to load the DataTemplate from string with XamlReader. Before that I have to edit the string to change the binding to wanted Candidate. Is there a better way how to create a DataGrid with unknown number of DataGridTemplateColumn? Note: This question is based on dynamic datatemplate with valueconverter

  • Eclipse - Import existing mult-rep CVS project folder

    - by iQ
    Hey guys, Wondering if anyone can help me out with eclipse in terms of importing an existing CVS managed project. I am currently trying to shift my work on to the eclipse IDE. Some details about my project and environment below. I'm working in Linux Ubuntu, the project folder is located on a mounted shared network drive, I have installed the "Eclipse CVS Client" plug-in for my version of eclipse (helios). I've tried many ways for eclipse to use my existing folder as a project and recognize the CVS data in the CVS folders. I have done the following options: Created a new project, selected existing source, located my project folder and clicked OK to finish creating. In the end the CVS files weren't automatically read. Did the same as above and after project creation I wen to the option "project menu-team-share project", it asks me to choose a repository and doesn't automatically find the CVS information in the subfolders. If your wondering I have set-up both repositories in my eclipse and can browse the repositories through the CVS browser. My project directory layout is like this: +-Project Folder (no CVS folder at this level) +---Repo A folder +-----CVS meta-info folder is INSIDE, along with all checked out files from Repo A + +---Repo B folder +-----CVS meta-info folder is INSIDE, along with all checked out files from Repo B + +-(couple of random files, not in CVS) Thanks for the help

  • Reuse, Rewrite, or Refactor?

    - by Jon Purdy
    At work I inherited development of a PHP-based Web site after the consultant who originally produced it bailed out and left without a trace. Literally half of the code is ripped from online tutorials, and there are thousands of lines of cruft that, being incomplete, do precious little. Hardly any of it actually works. I've been trying to pull out the usable components, such as the layout (cleverly intermixed with code), session management (delicately seasoned with unescaped, unvalidated SQL queries), and a few other things, but it's very difficult to force all of this junk into place. Further, I don't speak idiomatic PHP, being more of a Perl user, and I'm supposed to be on this project principally for maintenance, so rewriting everything seems like it would take just as long as wrestling the existing monster back into place. As an aside, I have literally never seen anything as badly written as this. Welcome me to the world of working with other people's code, I guess, but I do hope it's not this common in the real world to have such gems as these: // WHY IS THIS NOT WORKING // I know this is bad but were going for working stuff right now... // This is a PHP code outputing Javascript code outputting HTML...do not go further // Not userful I'm looking for the best advice I can get here. What would you do if you were in my position?

  • Python __subclasses__() not listing subclasses

    - by Mridang Agarwalla
    I cant seem to list all derived classes using the __subclasses__() method. Here's my directory layout: import.py backends __init__.py --digger __init__.py base.py test.py --plugins plugina_plugin.py From import.py i'm calling test.py. test.py in turn iterates over all the files in the plugins directory and loads all of them. test.py looks like this: import os import sys import re sys.path.append(os.path.join(os.path.abspath(os.path.dirname(os.path.abspath( __file__ ))))) sys.path.append(os.path.join(os.path.abspath(os.path.dirname(os.path.abspath( __file__ ))), 'plugins')) from base import BasePlugin class TestImport: def __init__(self): print 'heeeeello' PLUGIN_DIRECTORY = os.path.join(os.path.abspath(os.path.dirname(os.path.abspath( __file__ ))), 'plugins') for filename in os.listdir (PLUGIN_DIRECTORY): # Ignore subfolders if os.path.isdir (os.path.join(PLUGIN_DIRECTORY, filename)): continue else: if re.match(r".*?_plugin\.py$", filename): print ('Initialising plugin : ' + filename) __import__(re.sub(r".py", r"", filename)) print ('Plugin system initialized') print BasePlugin.__subclasses__() The problem us that the __subclasses__() method doesn't show any derived classes. All plugins in the plugins directory derive from a base class in the base.py file. base.py looks like this: class BasePlugin(object): """ Base """ def __init__(self): pass plugina_plugin.py looks like this: from base import BasePlugin class PluginA(BasePlugin): """ Plugin A """ def __init__(self): pass Could anyone help me out with this?

  • Best practises for Magento Deployment

    - by Spongeboy
    I am looking setting up a deployment process for a highly customised Magento site, and was wondering how other people do this. I will be setting up dev, UAT and prod environments. All the Magento files will be in source control (SVN). At this stage, I can't see any requirements for changing the DB, so the 3 databases will be manually maintained. Specifically, How do you apply Magento upgrades? (Individually in each env, or on dev then roll out, or just give up on upgrades?) What files/folders do leave alone in each environment (e.g. magento/app/etc/local.xml) Do you restrict developers to editing specific files/folders? Do you restrict theme designers to editing specific files/folders? How do you manage database changes? Theme Designer Files/Folders Designers can restricted to editing the following folders- app/design/frontend/your_interface/your_theme/layout/ app/design/frontend/your_interface/your_theme/template/ app/design/frontend/your_interface/your_theme/locale/ skin/frontend/your_interface/your_theme/ Extension Developer Files/Folders Extension developers can edit the following folders/files- /app/code/local /app/etc/modules/<Namespace>_<Module>.xml Database environment management As the store's base URL is stored in the database, you cannot just copy databases between environments. Options include- Overriding the base url in php. Blog article on setting up dev and staging databases Changing the base url in the database after copying. (Where is this stored?) Doing a MySQLDump or backup, then doing a replace on the URL in the SQL file.

  • Having issue Deserializing array from an XML string

    - by LeeHull
    I'm having issues trying to deserializing my xml string that was from a dataset.. Here is the XML layout.. <DataSet> <User> <UserName>Test</UserName> <Email>[email protected]</Email> <Details> <ID>1</ID> <Name>TestDetails</Name> <Value>1</Value> </Details <Details> <ID>2</ID> <Name>Testing</Name> <Value>3</Value> </Details </User> </DataSet> Now I am able to deserialize the "UserName" and "Email" when doing public class User { public string UserName {get;set;} public string Email {get;set;} public Details[] Details {get;set;} } public class Details { public int ID {get;set;} public string Name {get;set;} public string Value {get;set;} } This deserializes fine when I just get the user node, the Details isnt null but has no items in it.. i know I am suppose to have between all the details but I rather not modify the XML, anyways to get this to deserialize properly without recreating the XML after I get it?

  • suggestions for declarative GUI programming in Java

    - by Jason S
    I wonder if there are any suggestions for declarative GUI programming in Java. (I abhor visual-based GUI creator/editor software, but am getting a little tired of manually instantiating JPanels and Boxes and JLabels and JLists etc.) That's my overall question, but I have two specific questions for approaches I'm thinking of taking: JavaFX: is there an example somewhere of a realistic GUI display (e.g. not circles and rectangles, but listboxes and buttons and labels and the like) in JavaFX, which can interface with a Java sourcefile that accesses and updates various elements? Plain Old Swing with something to parse XUL-ish XML: has anyone invented a declarative syntax (like XUL) for XML for use with Java Swing? I suppose it wouldn't be hard to do, to create some code based on STaX which reads an XML file, instantiates a hierarchy of Swing elements, and makes the hierarchy accessible through some kind of object model. But I'd rather use something that's well-known and documented and tested than to try to invent such a thing myself. JGoodies Forms -- not exactly declarative, but kinda close & I've had good luck with JGoodies Binding. But their syntax for Form Layout seems kinda cryptic. edit: lots of great answers here! (& I added #3 above) I'd be especially grateful for hearing any experiences any of you have had with using one of these frameworks for real-world applications. p.s. I did try a few google searches ("java gui declarative"), just didn't quite know what to look for.

  • New to Android: Dynamically changing views

    - by Josiah Kiehl
    I'm trying to learn how to build apps for Android. The first simple app, which will become a component of a bigger app I hope to build, is to have a button on the screen where, when tapped, it adds something new to the view. For instance: Imagine a layout that only has a button: [Create!] When that button, the view gets a new row added to it: [Create!] A Something! Upon subsequent presses, more rows are added [Create!] A Something! A Something! And so on. I've made a LinearLayout and placed the button in it, and have attached a click listener to it. That all works great. What I can't figure out is how to get a handle on the LinearLayout in the onClick function with which I'll addView() the new TextView that says "A Something!" Am I on the right track? What basic thing am I missing? Thanks!

  • HTML5 Shiv not parsing quick enough

    - by Mikey Hogarth
    One of our web designers is working on a site at the moment and is using HTML5 elements, which she styles up in older browsers using the well documented Html5Shiv; http://css-tricks.com/html5-innershiv/ She reported some pretty weird behavior today and it looks like this is the cause. Initially it was very confusing, and went something along the lines of; "The page looks fine, I refresh it looks fine, refresh several times and occasionally it will not apply my styles to the HTML5 elements" Current best theory is that the shiv is not kicking in quick enough, and the page loads before the new elements have been registered. I was wondering if anyone could suggest a surefire way of including the shiv and making sure it's loaded and been parsed BEFORE the rest of the elements, so they will definitely get styled. EDIT (more info) Shiv is being included in the head, directly below the title/meta tags; <!--[if IE]> <script type="text/javascript" src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> The bit that is being styled is in the footer and is cross-site. Many of the pages will change in size as they're being powered by a CMS that our marketing team will use so I am unable to give an exact page size. All I would say is that if page size is an issue and there is no workaround, can someone let me know as this will mean we basically can't use HTML5 on this project (or at the very least we'll need to add superflous markup such as divs to ensure that the layout doesn't go crazy) EDIT 2 There is no chance of me posting the code unfortunately - it's only re-creatable under really obscure circumstances and the project is marked "top secret" at the moment :( If nobody knows then I'm guessing it's either a case of "everyone knows it happens but kinda ignores it" or just that it's something else other than the shiv.

  • JSF/Seam - call one component method for many radio groups

    - by purecharger
    I've got the following jsf page: <h:form> <ui:repeat value="#{list.categories}" var="cat"> <h:selectOneRadio id="sel1Rad" value="#{list.choose}" layout="pageDirection"> <f:selectItems value="#{list.names}"/> </h:selectOneRadio> </ui:repeat> <h:commandButton id="submit" action="#{list.submit}" value="Submit"/> </h:form> And a component named list. The variable cat is injected to the component, used by the method list.getNames(). What I am trying to have happen is to have list.choose() be called for each radio group. I'm not sure if this is possible with Seam. Going by the booking example distributed with Seam, there is a distinct separate method for each selectOneRadio or selectOneMenu group. Since I have an unknown number of categories, I can't / don't want to define a method for each possible choice. When I submit the form, all my choices are sent in the POST, I just don't know the correct way to tell Seam how to dispatch them to my component. Any help is appreciated!

  • How can I improve this search usability?

    - by Craig Whitley
    This is the first real programming attempt of mine, and theres some major flaws. It's a learning project, and I'm currently re-writing the entire thing as my php is is really messy. I really want to get an idea on how I can improve the actual usability and accesibility of the site at the same time though - so I know how to implement it correctly. The website is basically a comparison website for gameserver hosting. As I mentioned, its a learning project and I don't actually expect any revenue from it. At the moment theres only test data in it, so in the game input box select either 'Battlefied Bad Company 2' or 'Call of Duty 4: Modern Warfare' and ignore the actual search results. http://www.laglessfrag.com I wasn't really sure how to work the search functionality. Basically when you click a game in the drop down box, it sends an ajax request and finds all the locations available to that specific game in the database. After selecting the country theres another ajax to find all the citys available to the game in that country - which gives me the two unique identifiers I need to create the search results. One major and fundamental flaw is that without javascript enabled, the site ceases to function. I'll overcome that in the next re-write, but without the ajax functionality stopping the user 'going wrong' - how can I implement a search that requires two fields without creating extra steps in new pages after form submissions? I'm also no designer so my whole layout and css is a bit rubbish, but this was mainly a learning project as I'm interested in applications / programming rather than design. It's also slow as its on shared hosting, but if I can get it to work correctly then I'm not impartial to chucking a bit of money at it for faster hosting and maybe a bit of advertising and seeing where it goes (if anywhere!). Any info appreciated.

  • Creating content for rails-based applications

    - by Matthias Hryniszak
    Hi, I'm facing a problem of cleaning up my application in Ruby on Rails. What I have is a pretty standard 3-panel, header and footer layout where different parts of the screen contain different functionality. By that I mean for example that the header contains (among others) a select that allows one to select parts of the application and a context-dependent menu. The main content area contains obviously the most interactive stuff whereas side panels contain quick-links with stuff like shopping-cart preview, list of potentially attractive products for the customer, a selector to narrow down the list of options... I was wondering how do I go about simplifying the design. Right now I have the stuff that provides data for the "common" stuff (as opposed to direct content that's placed in the center) called from all the actions (with a filter) but that doesn't feel right for me. I've read that "components" are also not the way to go for obvious performance reasons. Is there something that's more like component-oriented (other frameworks do have that kind of stuff - Grails: <ui:include ../>, ASP.NET MVC: <% Html.RenderAction() %>)? Best regards, Matthias.

  • jQuery image hover color overlay

    - by Ryan Max
    I can't seem to find any examples of this having been done anywhere on the internet before but here is what I am going to attempt to do...I'm trying to go about the cleanest possible way of laying this out. So I have an image gallery where the images are all different sizes. I want to make it so that when you mouseover the image, it turns a shade of orange. Just a simple hover effect. I want to do this without using an image swap, otherwise I'd have to create an orange colored hover-image for each individual gallery image, I'd like this to be a bit more dynamic. My plan is just to position an empty div over the image absolutely with a background color, width and height 100% and opacity: 0. Then using jquery, on mouseover I'd have the opacity fade to 0.3 or so, and fade back to zero on mouseout. My question is, what would be the best way to layout the html and css to do this efficiently and cleanly. Here's a brief, but incomplete setup: <li> <a href="#"> <div class="hover">&nbsp;</div> <img src="images/galerry_image.png" /> </a> </li> .hover { width: 100%; height: 100%; background: orange; opacity: 0; }

  • Help regarding Android NDK

    - by Siva Kumar
    I am a beginner in using Android NDK. I am using Eclipse and I installed cygwin to build the c file to generate the .so file But while building the c file in cygwin I am always getting the error make: ***No rule to make target 'file.c' ... .Stop I tried building different C codes but for every file it says the same error .. Here is the source code: public class ndktest extends Activity { static { System.loadLibrary("ndkt"); } private native void helloLog(String logThis); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); helloLog("this is to test log file"); } } file.c void Java_com_ndktest_helloLog(JNIEnv * env, jobject this, jstring logThis) { jboolean isCopy; const char * szLogThis = (*env)->GetStringUTFChars(env, logThis, &isCopy); (*env)->ReleaseStringUTFChars(env, logThis, szLogThis); } And here is my Android.mk LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_LDLIBS := -llog LOCAL_MODULE := ndkt LOCAL_SRC_FILES := file.c include $(BUILD_SHARED_LIBRARY) I searched for the solution for the cause of error ... but nothing works for me. Can anyone tell me where I am making the mistake ? Thanks, Siva Kumar

  • new page/forward in javascript

    - by acidzombie24
    I am making a greasemonkey script and i would like a link to go forward and modify the current html and allow the user to click back to go to the original page. How might i do this? using jquery + greasemonkey + javascript. Targeting firefox mostly. -edit- http://jsfiddle.net/ seems to do it. If you write random html in the html section, hit run, change the html and hit run again. You'll be able to click back/forward to see the output change (however the html input box stays the same). I am using firefox to view this. Thats the effect i want. it appears the magic is done on line 91. Is this submitting a form in a frame (perhaps the results frame?) and that is causing the movement in history? 88 run: function(e) { 89 e.stop(); 90 Layout.updateFromMirror(); 91 document.id(this.options.formId).submit(); 92 this.fireEvent('run'); 93 },

  • Bizarre problem with WPF XAML file.

    - by paxdiablo
    I've just started a very simple WPF application which consists of a main large image and four smaller images. In order to assist with the layout, I created some JPEGs in MsPaint containing the images -2, -1, 0, +1 and +2 and just copied them into the top level of the project directory. The XAML segment contains, for the five images: <Image Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="4" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicture" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/zero.jpg" <Image Grid.Column="1" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicMinus2" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/minus2.jpg" <Image Grid.Column="2" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicMinus1" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/minus1.jpg" <Image Grid.Column="3" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicPlus1" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/plus1.jpg" <Image Grid.Column="4" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicPlus2" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/plus2.jpg" When I try to set the source property for the plus2 image, it complains with a dialog box stating: Property value is not valid. Details | V The file plus2.jpg is not part of the project or its 'Build Action' property is not set to 'Resource'. Yet if I rename the file to plus3.jpg or plus2x.jpg, I don't have that problem. Why is it complaining about plus2.jpg specifically?
