  • help with rails render action vs routing

    - by Stacia
    I was using some image cropping example that I found online and now I got confused. There is actually no "crop" method in my controller. Instead (following the guide) I put a render :action => 'cropping', :layout=> "admin" In my create method. That renders a page the view called cropping.html.erb . It works fine but I have no idea how to link or render that page otherwise, like if I wanted to hit a URL directly or press a button to recrop an image. Should I actually create a crop method in my controller and hook it up via routing if I want to be able to do this, or is there a way within my view to link to the same place that renders the cropping action? Sorry about the confusion :) It doesn't help that the first version of the tutorial did have a cropping method and he removed it!! Any explanation on why one method is better over the other would be great. Thanks!!

  • Fixed footer not displaying the bottom-most list item

    - by Mohit Deshpande
    Here is my XML layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ListView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/list" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content"> </ListView> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentBottom="true"> <EditText xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="1" /> <Button xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="2" /> </LinearLayout> </RelativeLayout> Which causes this problem: The listview item (outlined in red) is behind the fixed footer and cannot be used. Any solutions?

  • Microsoft Expression Web 3 clipboard bug

    - by Ghostrider
    There seems to be a rather annoying bug in MS Expression Web 3 (or perhaps an incompatibility with something else I have installed). Quite often HTML code editor would refuse to copy things into clipboard. You select some text, press Ctrl-C, Ctrl-Insert or use context menu and nothing happens. Then in 10..15 seconds it would start working again... Then again it would not work. It's rather annoying. Does anyone else have such a problem or knows how to fix it? I'm running Microsoft Expression Web 3 Service Pack 1 Version 3.0.3813.0 on Windows 7 Ultimate x64 with all latest updates and patches. I have Russian keyboard layout installed. Other than that my system is pretty much plain vanilla.

  • Soft keyboard does not show when Activity starts

    - by Sarp Centel
    I have added android:windowSoftInputMode="stateAlwaysVisible" to my Activity in AndroidManifest.xml and here's my layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:id="@+id/EditText01" android:layout_width="wrap_content" android:layout_height="wrap_content"></EditText> <EditText android:id="@+id/EditText02" android:layout_width="wrap_content" android:layout_height="wrap_content"></EditText> <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Send"></Button> </LinearLayout> When the Activity starts, the EditText is focused, but soft keyboard isn't displayed. If I click on the EditText, then I see the soft keyboard. Do I need to set aditional parameters to display soft keyboard when my Activity starts? Thanks

  • Java MVC - How to divide a done text game into MVC?

    - by Zopyrus
    Been sitting here for hours now trying to figure this out, so a bit sympathy for this large question. :) The Goal: I simply want to divide my done code into MVC (Model View Controller) parts. I have the game logics done and text based - the code works fine. The Problem: Well, I want to implement this code into MVC, but where do explain for the MODEL that it should use text-based? Because the VIEW is only for the layout (graphically) correct? I am having a REALLY hard time figuring out where to begin at all. Any pointers would be so nice! Here is my game logics code: import mind.*; import javax.swing.*; import java.util.*; import java.lang.*; import java.awt.*; public class Drive { String[] mellan; boolean gameEnd, checkempty, checkempty2, enemy, enemy2; String gr,rd,tom; int digits; public Drive() { // Gamepieces in textform gr="G"; rd="R"; tom=" "; mellan = new String[7]; String[] begin = {gr,gr,gr,tom,rd,rd,rd}; String[] end = {rd,rd,rd,tom,gr,gr,gr}; //input Scanner in = new Scanner(System.in); mellan=begin; gameEnd=false; while (gameEnd == false) { for(int i=0; i<mellan.length; i++) { System.out.print(mellan[i]); } System.out.print(" Choose 0-6: "); digits = in.nextInt(); move(); checkWin(); } } void move() { //BOOLEAN for gameruls!!! checkempty = digits<6 && mellan[digits+1]==tom; checkempty2 = digits>0 && mellan[digits-1]==tom; enemy = (mellan[digits]==gr && mellan[digits+1]==rd && mellan[digits+2]==tom); enemy2 = (mellan[digits]==rd && mellan[digits-1]==gr && mellan[digits-2]==tom); if(checkempty) { mellan[digits+1]=mellan[digits]; mellan[digits]=tom; } else if (checkempty2) { mellan[digits-1]=mellan[digits]; mellan[digits]=tom; } else if (enemy) { mellan[digits+2]=mellan[digits]; mellan[digits]=tom; } else if (enemy2) { mellan[digits-2]=mellan[digits]; mellan[digits]=tom; } } void checkWin() { String[] end = {rd,rd,rd,tom,gr,gr,gr}; for (int i=0; i<mellan.length; i++){ } if (Arrays.equals(mellan,end)) { for (int j=0; j<mellan.length; j++) { System.out.print(mellan[j]); } displayWin(); } } void displayWin() { gameEnd = true; System.out.println("\nNicely Done!"); return; } // Kör Drive! public static void main(String args[]) { new Drive(); } } Here is how I defined my DriveView thus far: (just trying to make one button to work) import mind.*; import javax.swing.*; import java.util.*; import java.lang.*; import java.awt.*; import java.awt.event.*; public class DriveView extends JFrame { JButton ruta1 = new JButton("Green"); JButton ruta2 = new JButton("Green"); JButton rutatom = new JButton(""); JButton ruta6 = new JButton("Red"); private DriveModel m_model; public DriveView(DriveModel model) { m_model = model; //Layout for View JPanel myPanel = new JPanel(); myPanel.setLayout(new FlowLayout()); myPanel.add(ruta1); myPanel.add(ruta2); myPanel.add(rutatom); myPanel.add(ruta6); this.setContentPane(myPanel); this.pack(); this.setTitle("Drive"); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } void addMouseListener(ActionListener mol) { ruta2.addActionListener(mol); } } And DriveController which gives me error at compile import mind.*; import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.lang.*; public class DriveController { private DriveModel m_model; private DriveView m_view; public DriveController(DriveModel model, DriveView view) { m_model = model; m_view = view; view.addMouseListener(new MouseListener()); } class MouseListener implements ActionListener { public void actionPerformed(ActionEvent e) { String mening; mening = e.getActionCommand(); if (mening.equals("Green")) { setForeground(Color.red); } } } }

  • using Control.tabs for prototype.js in Rails

    - by Elliot
    Hey everyone, I've been trying to use http://livepipe.net/control/tabs to get some javascript tabs up and running on my rails up. I'm really just trying to figure out how to install this... and I don't see how I'm running into any issues at all. Here are the steps I've taken: put tabs.js in my scripts folder made sure the layout is including all javascript files then I copied in the code for example 1, as well as the CSS from the page's style sheet. I don't get an error, but it just doesn't work. Both tabs are displayed... Any ideas?

  • Prevent line break between two elements in CSS

    - by Paul Alexander
    For some basic layout work I'm doing, I'd like links that immediately follow a price to always be shown on the same line as the price. The price text is wrapped in a <span class="price"> tag while the link uses the buy-link class as in <a href="/buy" class="buy-link">Buy Now</a>. I'm looking for CSS that will automatically prevent line breaking between the span and a tag but I'm either missing something or it can't be done. I can easily prevent line breaks within the two tags - but not between them. I want to avoid wrapping both tags in a span with a white-space: nowrap manually and use pure CSS if possible.

  • How do I combine two methods into one json formatted variable?

    - by JZ
    I'm storing JSON formatted data into a var adds with the following methods: var adds = <%= raw @add.to_a.to_json %>; var adds = <%= raw @add.nearbys(1).to_json %>; The first line of code stores the location of an individual in JSON format, the second line of code searches for that person's neighbors, within a 1 mile range. How do I combine both of these lines of code and store the data in JSON format in the var adds variable? If you are interested in source, its here. The location is layout/adds.html.erb

  • Android RadioButton like Behaviour

    - by monxalo
    Greetings, I'm trying to create a single-choice android control, in a horizontal layout, by making use of the RadioGroup behaviour. I can assign the drawable just fine, but i would like to position the label of each RadioButton inside the drawable, is this possible using the standard APIs? <RadioGroup android:id="@+id/switchcontainer" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" android:checkedButton="@+id/RadioButton02" android:padding="3dip"> <RadioButton android:text="id RadioButton02" android:id="@+id/RadioButton02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:button="@drawable/radio_button" android:paddingRight="2dip" /> <RadioButton android:text="@+id/RadioButton03" android:id="@+id/RadioButton03" android:layout_width="wrap_content" android:layout_height="wrap_content" android:button="@drawable/radio_button" android:paddingRight="2dip" />> </RadioGroup>

I'm trying to branch out to actual mobile development now, so I checked out Dashcode. Anyway, I'm trying to put a Call Button, Mail Button, and Map Button in horizontal alignment. I realize that I can add a Column Layout and have two buttons in a row, but that's the most I've gotten. Any ideas? Thanks! Thomas

    TLDR I want to add some dynamic content into an Ext-JS window / popup. Currently I have tried assigning this content to a div and pulling on the innerhtml of that div like: new Ext.Window({ height: 50, width: 160, x: 0, y: 30, layout: "fit", html: document.getElementById('output').innerHTML; }).show(); Am using jquery & getjson to get the dynamic data.

  • Add Today's Date to SharePoint Master Page

    - by soniiic
    Surely there must be a simple way of putting a simple code block into a master page :( I've tried using the obvious <%= "Hello, World!" %> syntax but code blocks aren't allowed. Then tried a site column, but don't know how to use them. Then tried web zones but master pages can't use them. Tried putting a web part (which are super difficult to make and deploy btw) into the page layout, but it just doesn't render :/ All I want is something nice and simple at the top of my site which shows today's date and the format I want to use is DateTime.Today.ToString("ddd, d MMMM yyyy") (Otherwise I'm resorting to javascript document.write!) Thanks all,

  • Is there anyway I can fix a webview?

    - by Legend
    I am trying to load a webpage into a sample webview that I created: public class HelloWebview extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); WebView webview; webview = (WebView) findViewById(R.id.webview); webview.getSettings().setDefaultZoom(ZoomDensity.FAR); webview.setHorizontalScrollBarEnabled(false); webview.setVerticalScrollBarEnabled(false); webview.getSettings().setJavaScriptEnabled(true); webview.loadUrl("http://10.0.2.2/index.html"); } } Initially, I had a problem with the scrollbars so I added the two lines to disable them. Now, I am still able to pan around the webpage though the scroll bars are not visible. How can I fix the view so that I am not able to pan (or scroll) the webpage? By panning, I mean moving around the webpage with an onTouch event.

  • how to create a 2 column to seperate label and input element in a form

    My form looks like: ** <p><label>first name</label><input type=text name=fn /></p> <p><label>last name</label><input type=text name=ln /></p> </div> <div id="rightform"> <p><label>state</label><input type=text name=state /></p> <p><label>city</label><input type=text name=city /></p> </div> ** I want the layout so all the labels line up on the left (with the label text right-aligned), and the input box all lined up, floating to the left. So the form should look like: asdf-label INPUTBOX 123-label INPUTBOX yet-another-label INPUTBOX There will be another form on the right side of the above form (with the id=#rightform) Really confused how to do this properly...

  • Seemingly useless debugging environment for Android

    - by mikeY
    I've just started debugging my first three line long android app and I can't seem to use the debug tool like I want to. Here's my code: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); int a = 1 / 0; } Now I expect the debugger to halt the thread and show me the line number of statement where the division by zero occurs. No, instead it shows some other method internal to the system for which I have no source. To make the matters worse, there is no exception message either. Prior to this app, I created one which would do something when a button was pressed. If any exception was raised, again no useful line number or exception message would be shown. As of right now, there is no way to debug my app. Any ideas? I'm using the latest SDK along with Eclipse ADT plugin and debugging on a real device (Nexus One).

  • How to display a two column ListView in Android?

  • Rails, JSON Object, jQuery, Auto-Complete

    - by Michael Waxman
    I'm using this jquery autocomplete plug-in with rails: http://docs.jquery.com/Plugins/Autocomplete I can't figure out how to format my results, both in my Rails controller and in my javascript file. I have something like this in my controller... @query = params[:q].downcase @json = User.all(:login => /^#{@query}/) respond_to do |format| format.js { render :json => @json.to_json(:only => "login"), :layout => false } end And then this in my script.js file... $("#form").autocomplete('/url', { width: 320, dataType: 'json', highlight: false, scroll: true, scrollHeight: 300 }) But I can't figure out how to parse the data, so my autocomplete just gets a raw array of all my results at once. How do I process the JSON in the script.js file and/or in my controller for it to work?

  • How do I create an instance of this class in Android?

    - by Lloyd Banks
    I was wondering if it is possible to create an instance of this class (from the link, which creates a listview) from another class so that I can call on either lazyadapter.java or customizedlistview.java (not sure which one) to inflate that same listview. Is this possible? This is what I tried (obviously incorrect): CustomizedListView clv = new CustomizedListView(); clv.onCreate(...); source: http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/ LazyAdapter.java import java.util.ArrayList; import java.util.HashMap; import android.app.Activity; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.TextView; public class LazyAdapter extends BaseAdapter { private Activity activity; private ArrayList&lt;HashMap&lt;String, String&gt;&gt; data; private static LayoutInflater inflater=null; public ImageLoader imageLoader; public LazyAdapter(Activity a, ArrayList&lt;HashMap&lt;String, String&gt;&gt; d) { activity = a; data=d; inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); imageLoader=new ImageLoader(activity.getApplicationContext()); } public int getCount() { return data.size(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { View vi=convertView; if(convertView==null) vi = inflater.inflate(R.layout.list_row, null); TextView title = (TextView)vi.findViewById(R.id.title); // title TextView artist = (TextView)vi.findViewById(R.id.artist); // artist name TextView duration = (TextView)vi.findViewById(R.id.duration); // duration ImageView thumb_image=(ImageView)vi.findViewById(R.id.list_image); // thumb image HashMap&lt;String, String&gt; song = new HashMap&lt;String, String&gt;(); song = data.get(position); // Setting all values in listview title.setText(song.get(CustomizedListView.KEY_TITLE)); artist.setText(song.get(CustomizedListView.KEY_ARTIST)); duration.setText(song.get(CustomizedListView.KEY_DURATION)); imageLoader.DisplayImage(song.get(CustomizedListView.KEY_THUMB_URL), thumb_image); return vi; } } CustomizedListView.java import java.util.ArrayList; import java.util.HashMap; import org.w3c.dom.Document; import org.w3c.dom.Element; import org.w3c.dom.NodeList; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ListView; public class CustomizedListView extends Activity { // All static variables static final String URL = "http://api.androidhive.info/music/music.xml"; // XML node keys static final String KEY_SONG = "song"; // parent node static final String KEY_ID = "id"; static final String KEY_TITLE = "title"; static final String KEY_ARTIST = "artist"; static final String KEY_DURATION = "duration"; static final String KEY_THUMB_URL = "thumb_url"; ListView list; LazyAdapter adapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ArrayList&lt;HashMap&lt;String, String&gt;&gt; songsList = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;(); XMLParser parser = new XMLParser(); String xml = parser.getXmlFromUrl(URL); // getting XML from URL Document doc = parser.getDomElement(xml); // getting DOM element NodeList nl = doc.getElementsByTagName(KEY_SONG); // looping through all song nodes &lt;song&gt; for (int i = 0; i &lt; nl.getLength(); i++) { // creating new HashMap HashMap&lt;String, String&gt; map = new HashMap&lt;String, String&gt;(); Element e = (Element) nl.item(i); // adding each child node to HashMap key =&gt; value map.put(KEY_ID, parser.getValue(e, KEY_ID)); map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE)); map.put(KEY_ARTIST, parser.getValue(e, KEY_ARTIST)); map.put(KEY_DURATION, parser.getValue(e, KEY_DURATION)); map.put(KEY_THUMB_URL, parser.getValue(e, KEY_THUMB_URL)); // adding HashList to ArrayList songsList.add(map); } list=(ListView)findViewById(R.id.list); // Getting adapter by passing xml data ArrayList adapter=new LazyAdapter(this, songsList); list.setAdapter(adapter); // Click event for single list row list.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { } }); } }

  • What are the "Navigation Properties" in this data model for?

    - by d03boy
    I've been wondering how to properly set up many-to-many relationships in ASP.NET MVC 2 using Linq2Sql for quite some time now. I found this blog post that seems to have a similar model layout as mine. If you take a look at the first screenshot showing the data model you can see that each model has "Navigation Properties" at the bottom of it. What exactly is this and why don't my models have them? I have the proper foreign keys put in to place. Most specifically, I am looking at the relationship between the Article and Category models since that is the only many-to-many relationship that I see and that's what I'm trying to model. Obviously I use an intermediary joining table between these two tables but I am having trouble understanding the proper methodology for modeling that relationship and I'm not finding this information anywhere on The Google.

  • IE6 - body shrink on hover / z-index change

    - by Kasper
    I'm debugging a site to make it work for IE6 (god, please, let this be the last time). I've gotten pretty far with getting the the layout look right. There's just one more thing bugging me. Some elements like links, when they get hovered, the body of the site shrinks. I have built a dropdown with javascript. When it should show, the body of the site shrinks. There is a slideshow, made with javascript, which changes the z-index of the images, everytime it changes the z-index, the body shrinks. Now I found some information that IE6 creates this specific shrinking behaviour when using a fixed position element. But this is not the case. Someone here have some ideas for solving this? Thanks!

  • How do I change variables from different classes?

    - by Dan T
    Before I delve into it, I'm very new to Android and I have just started learning Java last month. I've hit bumps while trying to develop my first simple app. Most of these hurdles were jumped thanks to random tutorials online. MY CODE IS VERY MESSY. Any tips are appreciated. The question above is quite broad, but this is what I want to do: It's a essentially a blood alcohol content calculator / drink keeper-tracker. Basic layout: http://i.imgur.com/JGuh7.jpg The buttons along the bottom are just regular buttons, not ImageButtons (had problems with that) Here's some example code of one: <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_marginRight="5dp" android:background="@drawable/addbeer"/> The buttons and TextView are all in main.xml. I have variables defined in a class called Global.java: package com.dantoth.drinkingbuddy; import android.app.Activity; public class Global extends Activity{ public static double StandardDrinks = 0; public static double BeerOunces = 12; public static double BeerPercentAlcohol = .05; public static double BeerDrink = BeerOunces * BeerPercentAlcohol; public static double BeerDrinkFinal = BeerDrink * 1.6666666; public static double ShotOunces = 1.5; public static double ShotPercentAlcohol = .4; public static double ShotDrink = ShotOunces * ShotPercentAlcohol; public static double ShotDrinkFinal = ShotDrink * 1.6666666; public static double WineOunces = 5; public static double WinePercentAlcohol = .12; public static double WineDrink = WineOunces * WinePercentAlcohol; public static double WineDrinkFinal = WineDrink * 1.6666666; public static double OtherOunces; public static double OtherPercentAlcohol; public static double OtherDrink = OtherOunces * (OtherPercentAlcohol * .01); public static double OtherDrinkFinal = OtherDrink * 1.6666666; public static double GenderConstant = 7.5; //9 for female public static double Weight = 180; public static double TimeDrinking = 60; public static double Hours = TimeDrinking / 60; public static double Bac = ((StandardDrinks / 2) * (GenderConstant / Weight)) - (0.017 * Hours); } The last variable is the important part. It calculates your BAC based on the factors involved. When I press the add beer button (Button01) I make it add 1 to StandardDrinks, simulating drinking one beer. The other variables in the Bac formula have values assigned to them in Global.java. The code that makes the beer button do stuff is in my regular class, drinkingbuddy.java: public class DrinkingBuddy extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button button = (Button) findViewById(R.id.Button01); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Global.StandardDrinks = Global.StandardDrinks + Global.BeerDrinkFinal; Toast.makeText(DrinkingBuddy.this, "Mmmm... Beer", Toast.LENGTH_SHORT).show(); } }); By my perception, StandardDrinks should now have a value of 1. However, when I click the Calculate BAC button (Button05) it merely outputs the variable Bac as if StandardDrinks was still set to 0. Here is the code for the Calculate BAC button (Button05): Button button4 = (Button) findViewById(R.id.Button05); button4.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { TextView texty; texty = (TextView) findViewById(R.id.texty1); texty.setText("Your BAC is " + Global.Bac ); } }); It outputs the following to the text view: "Your BAC is -0.017". This is the Bac value for if StandardDrinks was still 0, so obviously there is some problem communicating between the classes. Can anyone help me?? The other elements of the formula (weight, time spent drinking, and the alcohol %'s and such) are variables because I will ultimately allow the user to change those values in the settings. I've heard around the water cooler that global variables are not good programming style, but this is the closest I've come to getting it to work. Any other ways of doing it are very much welcomed!

  • Reshape data frame to convert factors into columns in R

    - by Alexander L. Belikoff
    I have a data frame where one particular column has a set of specific values (let's say, 1, 2, ..., 23). What I would like to do is to convert from this layout to the one, where the frame would have extra 23 (in this case) columns, each one representing one of the factor values. The data in these columns would be booleans indicating whether a particular row had a given factor value... To show a specific example: Source frame: ID DATE SECTOR 123 2008-01-01 1 456 2008-01-01 3 789 2008-01-02 5 ... <more records with SECTOR values from 1 to 5> Desired format: ID DATE SECTOR.1 SECTOR.2 SECTOR.3 SECTOR.4 SECTOR.5 123 2008-01-01 T F F F F 456 2008-01-01 F F T F F 789 2008-01-02 F F F F T I have no problem doing it in a loop but I hoped there would be a better way. So far reshape() didn't yield the desired result. Help would be much appreciated.
