  • Are there IDEs in which the code-completion widget is not a linear list?

    - by Uri
    Most mainstream IDEs use code-completion in the form of a linear list of suggestions (typically methods). Are there any IDEs (mainstream or not) or IDE plugins that use a non-linear widget, such as a tree? (e.g., pick category first, then the actual recommendation)? I'm working on an IDE feature and want to make sure I'm not reinventing the wheel or infringing some patent.

  • Spinner cannot load an integer array?

    - by Adam
    I have an application, which has a Spinner that I want populated with some numbers (4,8,12,16). I created an integer-array object in strings.xml with the items mentioned above, set the entries of the Spinner to the integer-array, and when I run the app I get: 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): java.lang.NullPointerException 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:355) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.ArrayAdapter.getView(ArrayAdapter.java:323) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.AbsSpinner.onMeasure(AbsSpinner.java:198) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.View.measure(View.java:7965) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:2989) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:888) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.LinearLayout.measureVertical(LinearLayout.java:350) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.LinearLayout.onMeasure(LinearLayout.java:278) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.View.measure(View.java:7965) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:2989) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.FrameLayout.onMeasure(FrameLayout.java:245) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.View.measure(View.java:7965) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.LinearLayout.measureVertical(LinearLayout.java:464) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.LinearLayout.onMeasure(LinearLayout.java:278) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.View.measure(View.java:7965) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:2989) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.widget.FrameLayout.onMeasure(FrameLayout.java:245) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.View.measure(View.java:7965) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.ViewRoot.performTraversals(ViewRoot.java:763) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.view.ViewRoot.handleMessage(ViewRoot.java:1632) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.os.Handler.dispatchMessage(Handler.java:99) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.os.Looper.loop(Looper.java:123) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at android.app.ActivityThread.main(ActivityThread.java:4310) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at java.lang.reflect.Method.invokeNative(Native Method) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at java.lang.reflect.Method.invoke(Method.java:521) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 04-19 23:38:48.016: ERROR/AndroidRuntime(10193): at dalvik.system.NativeStart.main(Native Method) As soon as I changed the array to a string-array, this works fine.

  • Lightbox for embeddable JavaScript widget? Like Feedback tabs for UserVoice/GetSatisfaction

    - by Eliot Sykes
    There are so many lightboxes to choose from, I'm looking for a very lightweight one to use in an embedded javascript widget that would be used on a number of different web sites. This would work in a similar way to the GetSatisfaction/UserVoice feedback tab. Here are the requirements for the lightbox: Very small javascript download (animation not needed) Self contained, not dependent on any libraries such as jquery, etc. Works in major browsers Lightbox displays HTML content from a given URL Close button (like GetSatisfaction or UserVoice) Dims background Avoids javascript namespace conflicts (or can easily be made to avoid them) CSS styling of lightbox does not interfere with site styling Have you used an existing lightbox scripts for this same purpose with similar requirements? Did you roll your own? Insights welcome! Thanks, Eliot

  • Black flicker while resizing translucent Qt widget (only when Aero is enabled)?

    - by D.
    I have a top-level Qt widget with the FramelessWindowHint flag and the WA_TranslucentBackground attribute set. It has several children, each of which draws an image on it. They are not in a layout. Instead, I simply move them around when something changes (it is not user-resizable). There are two states to the window - a big state and a small state. When I switch between them, I resize the window and reposition the children. The problem is that as the window resizes, a black box is briefly flashed on the top-level window before the images are painted over it. The problem goes away if I disable Aero. I found brief mention of this problem being fixed in an article describing a new release of Qt (this release is long past), but it still doesn't work. Any ideas why? Thanks!

  • 2 different ways to define a widget in symfony, which to use?

    - by fayer
    in the tutorial i can use either: public function configure() { $this->setWidgets(array( 'type' => new sfWidgetFormChoice(array( 'choices' => Doctrine_Core::getTable('Gender')->getTypesForForm(), 'expanded' => false, 'multiple' => false, )) )); $this->widgetSchema['type'] = new sfWidgetFormChoice(array( 'choices' => Doctrine_Core::getTable('Gender')->getTypesForForm(), 'expanded' => false, 'multiple' => false, )); } to define a widget. i wonder which i should use and why there is 2 ways of writing this? thanks

  • Add the categories selector widget to the PAGE editor with predefined categories listed?

    - by Scott B
    The following code will add the categories selector widget to the WordPress Page editor interface... add_action('admin_menu', 'my_post_categories_meta_box'); function my_post_categories_meta_box() { add_meta_box('categorydiv', __('Categories'), 'post_categories_meta_box', 'page', 'side', 'core'); } What I would like to do is to figure out how to modify the resulting category listing so that it only contains a predefined list of hard coded categories that I define. Since I'm adding this via my custom theme, it will only appear on the page editor when my theme is active on the site. And I have some specific "handler" categories that my theme installs into the site and later uses to determine layout elements.

  • ASP.NET MVC Strongly Typed Widgets

    - by Ben
    I have developed a plugin system that makes it easy to plug in new logic to an application. Now I need to provide the ability to easily add UI widgets. There are already some good responses on how to create a portal system (like iGoogle) with ASP.NET MVC, and I'm fine about the overall concept. My question is really about how we make strongly typed widgets. Essentially when we set up a widget we define the controller and action names that are used to render that widget. We can use one controller action for widgets that are not strongly typed (since we just return PartialView(widgetControlName) without a model) For widgets that are strongly typed (for example to an IList) we would need to add a new controller action (since I believe it is not possible to use Generics with ActionResult e.g. ActionResult). The important thing is that the widget developers should not change the main application controllers. So my two thoughts are this: Create new controllers in a separate class library Create one partial WidgetController in the main web project and then extend this in other projects (is this even possible?) - not possible as per @mfeingold As far as the development of the widgets (user controls) go, we can just use post build events from our extension projects to copy these into the Views/Widgets directory. Is this a good approach. I am interested to here how others have handled this scenario. Thanks Ben P.S - in case it helps, an example of how we can render widgets - without using Javascript <%foreach (var widget in Model) {%> <%if (widget.IsStronglyTyped) { Html.RenderAction(widget.Action, widget.Controller); } else { Html.RenderPartial(widget.ControlName); } %> <%} %>

  • How to apply CSS theme to only a specific jQuery-UI element?

    - by Thierry-Dimitri Roy
    I have a web site already build with my own CSS theme. I'm using jQuery UI "tabs" widget but no CSS from jQuery-UI. Now, I'm trying to add the "Date Picker" widget in one of my page. It would be great if I could reuse jQuery-UI default theme which is just fine. The problem is that the date picker theme is also applied to my tabs CSS. For example the "ui-widget" css properties is applied to both date picker and tabs elements. I can't seem to find a way to apply the css properties to only the date picker. I can't see a "super selector" that only applies to the date picker DIV. What would be the best way to handle this? [EDIT] The datepicker widget is really the problem. I cannot apply CSS style specific to it. Here is the starting code of the DIV that get pops up: <div style="position: absolute; top: 300.4px; left: 149px; display: block;" id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible"><div class="ui-datepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> As such, I cannot add a super selector. What would be great would be that the date picker widget supports CSS scope. But it does not. I'm stuck manually editing the jQuery CSS file. The Date Picker is currently being refactored. Hopefully the new code will address this issue.

  • java + increasing performance and scalability

    - by varun
    Hi, below is the a code snippet, which returns the object of a class. now the object is basially comparing to some parameter in loop. my concern is what if there are thousands of objects in loop, in that case performance and scalability can be an issue. please suggest how to improve this code for performance part public Widget get(String name,int major,int minor,boolean exact) { Widget widgetToReturn = null; if(exact) { Widget w = new Widget(name, major, minor); // for loop using JDK 1.5 version for(Widget wid : set) { if((w.getName().equals(wid.getName())) && (wid.getVersion()).equals(w.getVersion())) { widgetToReturn = w; break; } } } else { Widget w = new Widget(name, major, minor); WidgetVersion widgetVersion = new WidgetVersion(major, minor); // for loop using JDK 1.5 version for(Widget wid : set) { WidgetVersion wv = wid.getVersion(); if((w.getName().equals(wid.getName())) && major == wv.getMajor() && WidgetVersion.isCompatibleAndNewer(wv, widgetVersion)) { widgetToReturn = wid; } else if((w.getName().equals(wid.getName())) && wv.equals(widgetVersion.getMajor(), widgetVersion.getMinor())) { widgetToReturn = w; } } } return widgetToReturn; }

  • What is a good way to render a site or portions of a site into a desktop gadget/widget?

    - by Daddy Warbox
    I guess a better way to ask this question (or an alternative to it, in my case) would be to first ask how to do this instead. Namely, I want to have a gadget on my desktop (not just in a browser window) with options such as overlaying on top of other windows, offline caching, etc. that is dedicated expressly to a given website (no browsing functions or menus). Be even more awesome if I could indicate a specific physical part of the website to show in the gadget.

  • How to set up RPX widget and facebook app to be able to authenticate with rpx_now?

    - by Andrei
    Using the sample app for rpx_now gem ( http://github.com/grosser/rpx_now_example) on localhost:3000, I have successfully logged in via Google Accounts, myOpenID, Yahoo, but cannot make it via Facebook. In the RPX app/widget settings I have set my facebook-app key and secret. In my facebook app settings, the Connect URL is myappname.rpxnow.com. But when I try to connect, then I don't even see a facebook login page, just a number of redirects and I am back to my localhost with the following exception http://gist.github.com/386520 . Before I was successfully connecting with oauth2 gem, however, without fetching user data - only authentication. That time I set only key/secret and localhost as my Connect URL. Currently, I don't even ask for email etc., but still the same problem. Can it happen because rpx_now cannot get requested user data from facebook? Or it is a problem of facebook key/secret? May be I need to provide more settings of my facebook app?

  • How to add a gwt widget to a gwt Composite already visible at runtime using MVP?

    - by mary4pfc
    Hi! I'm building an application whose menus depend on user roles. Once user is logged in and, therefore, her roles are known, I want to create the Hyperlinks related to the user and add them to the menu. I'm using MVP. Here's my code for the presenter: public class AdminMenuAreaPresenter extends WidgetPresenter<AdminMenuAreaPresenter.Display> { public interface Display extends WidgetDisplay{ public void addLink(String link); } private DispatchAsync dispatcher; private SessionManager sessionManager; @Inject public AdminMenuAreaPresenter(AdminMenuAreaPresenter.Display display, EventBus bus, DispatchAsync dispatcher, SessionManager sessionManager){ super(display, bus); this.dispatcher = dispatcher; this.sessionManager = sessionManager; this.bind(); } @Override protected void onBind() { super.onBind(); registerHandler(eventBus.addHandler(LoginEvent.TYPE, new LoginEventHandler() { @Override public void onLogin(LoginEvent event) { display.addLink("register user"); } })); } @Override protected void onUnbind() { // TODO Auto-generated method stub } @Override protected void onRevealDisplay() { // TODO Auto-generated method stub } } And here's the View: public class AdminMenuAreaView extends Composite implements AdminMenuAreaPresenter.Display{ private VerticalPanel vPanel; private Hyperlink registerUserLink; public AdminMenuAreaView(){ vPanel = new VerticalPanel(); initWidget(vPanel); } @Override public Widget asWidget() { return this; } public void addLink(String s){ registerUserLink = new Hyperlink(s, "this is new target"); this.vPanel.add(registerUserLink); registerUserLink.setVisible(true); } public HasClickHandlers getRegisterUserLink(){ return registerUserLink; } What am I doing wrong? Flow program goes throgh the addLink() method, but nothing is added to the view either dom document. Thank you.

  • Can I get vim to correctly indent this Ruby code (Nokogiri)?

  • Qt - drag and drop with graphics view framework

    - by David Davidson
    I'm trying to make a simple draggable item using the graphics framework. Here's the code for what I did so far: Widget class: class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = 0); ~Widget(); }; Widget::Widget(QWidget *parent) : QWidget(parent) { DragScene *scene = new DragScene(); DragView *view = new DragView(); QHBoxLayout *layout = new QHBoxLayout(); DragItem *item = new DragItem(); view->setAcceptDrops(true); scene->addItem(item); view->setScene(scene); layout->addWidget(view); this->setLayout(layout); } Widget::~Widget() { } DragView class: class DragView : public QGraphicsView { public: DragView(QWidget *parent = 0); }; DragView::DragView(QWidget *parent) : QGraphicsView(parent) { setRenderHints(QPainter::Antialiasing); } DragScene class: class DragScene : public QGraphicsScene { public: DragScene(QObject* parent = 0); protected: void dragEnterEvent(QGraphicsSceneDragDropEvent *event); void dragMoveEvent(QGraphicsSceneDragDropEvent *event); void dragLeaveEvent(QGraphicsSceneDragDropEvent *event); void dropEvent(QGraphicsSceneDragDropEvent *event); }; DragScene::DragScene(QObject* parent) : QGraphicsScene(parent) { } void DragScene::dragEnterEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dragMoveEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dragLeaveEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dropEvent(QGraphicsSceneDragDropEvent *event){ qDebug() << event->pos(); event->acceptProposedAction(); DragItem *item = new DragItem(); this->addItem(item); item->setPos(event->pos()); } DragItem class: class DragItem : public QGraphicsItem { public: DragItem(QGraphicsItem *parent = 0); QRectF boundingRect() const; void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget = 0); protected: void mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event); void mouseMoveEvent(QGraphicsSceneMouseEvent *event); void mousePressEvent(QGraphicsSceneMouseEvent *event); void mouseReleaseEvent(QGraphicsSceneMouseEvent *event); }; DragItem::DragItem(QGraphicsItem *parent) : QGraphicsItem(parent) { setFlag(QGraphicsItem::ItemIsMovable); } QRectF DragItem::boundingRect() const{ const QPointF *p0 = new QPointF(-10,-10); const QPointF *p1 = new QPointF(10,10); return QRectF(*p0,*p1); } void DragItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget){ if(painter == 0) painter = new QPainter(); painter->drawEllipse(QPoint(0,0),10,10); } void DragItem::mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event){ } void DragItem::mouseMoveEvent(QGraphicsSceneMouseEvent *event){ } void DragItem::mousePressEvent(QGraphicsSceneMouseEvent *event){ QMimeData* mime = new QMimeData(); QDrag* drag = new QDrag(event->widget()); drag->setMimeData(mime); drag->exec(); } void DragItem::mouseReleaseEvent(QGraphicsSceneMouseEvent *event){ } main.cpp instantiates a Widget and shows it. When I try to drag the circle, the app just creates another circle over the original one, regardless of where I release the drag. qDebug() in DragScene's dropEvent() shows QPointF(0,0) everytime the drag ends. I'm having a hard time trying to understand exactly what I have to do, which classes I should subclass, which methods needs to be overriden, to make this work. The documentation on this isn't very detailed. I'd like to know how to make this work, and if there's some other, more comprehensive resource to learn about the graphics view framework, besides the official documentation (which is excellent btw, but it would be great if there was a more detailed treatise on the subject). EDIT: Following badgerr's advice, I replaced item-pos() in DragScene::dropEvent() with item-scenePos(), now the drop event creates a new circle in the drop site, which is more or less what I wanted. But the original circle is still in place, and while the drag is in progress, the item doesn't follow the mouse cursor. The QGraphicsSceneDragDropEvent documentation says that pos() should return the cursor position in relation to the view that sent the event, which, unless I got it wrong, shouldn't be (0,0) all the time. Weird. I've read in a forum post that you can use QDrag::setPixMap() to show something during the drag, and in examples I've seen pictures being set as pixmaps, but how do I make the pixmap just like the graphics item I'm supposed to be dragging?

  • Android ActivityGroup

    - by Vahag Vardanyan
    I know that ActivityGroup is in the "past", but I want to learn how to use it. So I write a simple TabHost, and want to show different activities using ActivityGroup. Here are the parts of code Player.java package player.org; import android.app.Activity; import android.app.TabActivity; import android.content.Context; import android.content.Intent; import android.content.res.Resources; import android.media.MediaPlayer; import android.os.Bundle; import android.util.Log; import android.view.MotionEvent; import android.view.View; import android.view.View.OnClickListener; import android.view.animation.AlphaAnimation; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.widget.Button; import android.widget.ProgressBar; import android.widget.SeekBar; import android.widget.SeekBar.OnSeekBarChangeListener; import android.widget.TabHost; import android.widget.TabWidget; import android.widget.TextView; public class Player extends TabActivity { /** Called when the activity is first created. */ private MediaPlayer media=null; private SeekBar progress; private View play; private Progress p; TabHost tabhost; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.tabs); Resources res=getResources(); //TabHost tabhost=(TabHost) findViewById(R.id.tabhost); // tabhost.setup(); tabhost=getTabHost(); TabHost.TabSpec spec; Intent intent; intent=new Intent(this,Progress.class); spec=tabhost.newTabSpec("now playing").setIndicator("Now playing", res.getDrawable(R.drawable.icon)) .setContent(intent); tabhost.addTab(spec); intent=new Intent(this,Group.class); spec=tabhost.newTabSpec("all_songs").setIndicator("All songs", res.getDrawable(R.drawable.songs)) .setContent(intent); tabhost.addTab(spec); //intent=new Intent(this,Progress.class); spec=tabhost.newTabSpec("artists").setIndicator("Artists", res.getDrawable(R.drawable.icon)) .setContent(intent); tabhost.addTab(spec); spec=tabhost.newTabSpec("alboom").setIndicator("Alboom", res.getDrawable(R.drawable.icon)) .setContent(intent); tabhost.addTab(spec); tabhost.setCurrentTab(0); } } Group.java import android.os.Bundle; import android.view.View; public class Group extends ActivityGroup { @Override public void onCreate(Bundle savedInstanceStated) { super.onCreate(savedInstanceStated); View view = getLocalActivityManager().startActivity("AllSongs", new Intent(this, AllSongs.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); setContentView(view); } AllSongs.java package player.org; import java.util.ArrayList; import android.R.id; import android.app.ActivityGroup; import android.app.ListActivity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.Window; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.TabHost; public class AllSongs extends ListActivity{ ArrayList<String> listItem=new ArrayList<String>(); ArrayAdapter<String> adapter; ListView listView; //Player p; TabHost tab; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //p=new Player(); adapter=new ArrayAdapter<String>(this,R.layout.list_item,listItem); setListAdapter(adapter); listView=getListView(); listView.setTextFilterEnabled(true); listView.setOnItemClickListener(listener); addItem("vahag"); addItem("vahagvahag"); } private OnItemClickListener listener=new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub Intent intent = new Intent(AllSongs.this,Progress.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); Group group= (Group) getParent(); View view=group.getLocalActivityManager().startActivity("Progress",intent).getDecorView(); setContentView(view); } }; public void addItem(String s) { listItem.add(s); adapter.notifyDataSetChanged(); } } and the Progress.java package player.org; import android.app.Activity; import android.app.ActivityGroup; import android.app.Dialog; import android.app.TabActivity; import android.content.Context; public class Progress extends Activity { // Called when the activity is first created. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } So, AllSongs.java try to change current activity with Progress activity, but when I press on list item, the Programm forsed closed, and logChat says "08-17 12:49:26.471: ERROR/AndroidRuntime(1500): java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'" I can't figure how to fix this problem, Can anyone helps?

  • Mac dashboard widgets not loading external images

    - by andrhamm
    I set out to make a quick Mac OS X dashboard widget. I read the documentation and was pleased to find out they use simple HTML, JS, and CSS. I created my widget and it works when I open the .html file in Firefox, but it does not work when I install the widget to the dashboard. The widget is simple: it displays the most recent image from a weather web cam stream. The image URLs look like this: http://webcam.com/stream.jpg?1274213999617. The timestamp is appended to the URL and the server automatically responds with the latest image for that time. I did not write the server script. The widget appears to be loading correctly, but the web cam image will not load. Notice the blue question mark in the upper left. The image should appear over the square background image. Is there any special procedure for loading external images into a widget?

  • Using Typeface.js within a GWT app

    - by dindeman
    I am looking for some sample Java code demonstrating how to get AJAX content displayed into a custom font using Typeface.js within a GWT app. I have tried a little bit by calling the following native function native void Typeface_renderDocument() /*-{ $wnd._typeface_js.renderDocument(); }-*/; after having filled the relevant widget with the AJAX content, and after calling the following function on the widget : void applyTypeface(Widget widget) { widget.addStyleName("typeface-js"); widget.getElement().getStyle().setProperty("fontFamily", "Helvetiker"); Typeface_renderDocument(); } ...where Helvetiker is a custom font (actually available from Typeface.js fonts page (http://typeface.neocracy.org/fonts.html). But that didn't work. I am looking forward to any suggestions since I am bit stuck here. Alternatively I would be interested in an example using cufón within GWT, although I am not so keen about the replacement by images that cufón does (which is the main reason why I was trying to use Typeface.js.)

  • PHP or C# script to parse CSV table values to fill in one-to-many table

    - by Yaaqov
    I'm looking for an example of how to split-out comma-delimited data in a field of one table, and fill in a second table with those individual elements, in order to make a one-to-many relational database schema. This is probably really simple, but let me give an example: I'll start with everything in one table, Widgets, which has a "state" field to contain states that have that widget: Table: WIDGET =============================== | id | unit | states | =============================== |1 | abc | AL,AK,CA | ------------------------------- |2 | lmn | VA,NC,SC,GA,FL | ------------------------------- |3 | xyz | KY | =============================== Now, what I'd like to create via code is a second table to be joined to WIDGET called *Widget_ST* that has widget id, widget state id, and widget state name fields, for example Table: WIDGET_ST ============================== | w_id | w_st_id | w_st_name | ------------------------------ |1 | 1 | AL | |1 | 2 | AK | |1 | 3 | CA | |2 | 1 | VA | |2 | 2 | NC | |2 | 1 | SC | |2 | 2 | GA | |2 | 1 | FL | |3 | 1 | KY | ============================== I am learning C# and PHP, so responses in either language would be great. Thanks.
