• Custom theme and sherlockActionBar

  - by Atomico

  I am doing a personal theme to use holo widget in 2.3 android. I did this: <resources xmlns:android="http://schemas.android.com/apk/res/android"> <style name="AppThemes" parent="@style/Theme.Sherlock"> <item name="android:editTextStyle">@style/EditTextAppTheme</item> <item name="android:checkboxStyle">@style/CheckBoxAppTheme</item> <item name="android:radioButtonStyle">@style/RadioButtonAppTheme</item> <item name="android:buttonStyle">@style/ButtonAppTheme</item> <item name="android:imageButtonStyle">@style/ImageButtonAppTheme</item> <item name="android:spinnerStyle">@style/SpinnerAppTheme</item> <item name="android:dropDownSpinnerStyle">@style/SpinnerAppTheme.DropDown</item> <item name="android:spinnerDropDownItemStyle">@style/SpinnerDropDownItemAppTheme</item> </style> </resources> the problem is that widgets don't take the correct style but take the default style. I tried to force assign the @style/EditTextAppTheme at an edittext and it worked.. so the problem is that the theme don't apply. any idea? update: the theme apply and work good..the solo problem is some edittext inside a dialog that show with the standard theme

• Qt/MFC Migration Framework tool: properly exiting DLL?

  - by User

  I'm using the Qt/MFC Migration Framework tool following this example: http://doc.qt.nokia.com/solutions/4/qtwinmigrate/winmigrate-qt-dll-example.html The dll I build is loaded by a 3rd party MFC-based application. The 3rd party app basically calls one of my exported DLL functions to startup my plugin and another function to shutdown my application. Currently I'm doing nothing in my shutdown function. When I load my DLL in the 3rd party app the startup function is called and my DLL starts successfully and I can see my message box. However if I shutdown my plugin and then try to start it again I get the following error: Debug Error! Program: <my 3rd party app> Module: 4.7.1 File: global\qglobal.cpp Line: 2262 ASSERT failure in QWidget: "Widgets must be created in the GUI thread.", file kernel\qwidget.cpp line 1233 (Press Retry to debug the application) Abort Retry Ignore This makes me think I'm not doing something to properly shutdown my plugin. What do I need to do to shut it down properly? UPDATE: http://doc.qt.nokia.com/solutions/4/qtwinmigrate/winmigrate-walkthrough.html says: The DLL also has to make sure that it can be loaded together with other Qt based DLLs in the same process (in which case a QApplication object will probably exist already), and that the DLL that creates the QApplication object remains loaded in memory to avoid other DLLs using memory that is no longer available to the process. So I wonder if there is some problem where I need to somehow keep the original DLL loaded no matter what?

• SWT: scrollable area within a tab

  - by DaveJohnston

  I am trying to add a scrollable area to my tabbed window. So far I have a CTabFolder in a shell. I have added 5 CTabItems to it and everything works as expected. On one of my CTabItems the contents are too big to fit on the screen so I would like to be able to scroll. The contents is a collection of Groups each containing various widgets. So the CTabFolder is created as follows: CTabFolder tabs = new CTabFolder(shell, SWT.BORDER); tabs.setSimple(false); tabs.setUnselectedImageVisible(false); tabs.setUnselectedCloseVisible(false); tabs.setMinimizeVisible(false); tabs.setMaximizeVisible(false); FormData tabsLayoutData = new FormData(); tabsLayoutData.top = new FormAttachment(0, 5); tabsLayoutData.left = new FormAttachment(0, 5); tabsLayoutData.bottom = new FormAttachment(92, 0); tabsLayoutData.right = new FormAttachment(100, -5); tabs.setLayoutData(tabsLayoutData); Then the CTabItem: CTabItem tab = new CTabItem(tabs, SWT.NONE); tab.setText("Role"); Then the contents: Composite tabArea = new Composite(tabs, SWT.V_SCROLL); tabArea.setLayout(new FormLayout()); tab.setControl(tabArea); So the groups contained within the tab are created with tabArea as the parent and everything appears as you would expect. The problem is though that the vertical scroll bar is always present but doesn't seem to do anything. The contents are chopped off at the bottom of the tabArea composite. Is there anything else I need to do to get the scrolling to work properly?

• What java web application framework to use?

  - by frohiky

  One of the main products of my company is an Oracle Forms (and Reports) based application, that "needs" to be re-written in another technology. Why? Users want a more rich interface experience, and we want, preferably, to reduce costs with an open source application server. For this (HUGE) project, we intend to use a java web application framework, keep these points in mind: We have: hundreds of tables on our database (the ORM must be as flexible as possible); some logic which is (and will still be) based on PL/SQL procedures/functions/packages; a lot of CRUDs (the application itself is of an considerable size); a demand to work with/generate documents and workflows; an intranet based user environment; We want: to offer a RIA interface experience; use (if possible) an open source app server; a rapid (as possible) development framework; a somewhat mature framework with a "wise" roadmap (and a considerable community support); a MVC approach combined with JS or GWT widgets (e.g. Vaadin or SmartGWT); Well, in the past weeks I've read a lot of posts, Q&As on stackoverflow, and much more: Wicket, JSF, Tapestry, Grails, GWT, Struts2, Play, Spring, Seam, Echo, .... the list goes on! I've even researched about Alfresco..! The obvious question: Which one to use? At this time, any insight, recommendation, shared experience, advice will be more then welcome!

• What are some good ways to store performance statistics in a database for querying later?

  - by Nathan

  Goal: Store arbitrary performance statistics of stuff that you care about (how many customers are currently logged on, how many widgets are being processed, etc.) in a database so that you can understand what how your servers are doing over time. Assumptions: A database is already available, and you already know how to gather the information you want and are capable of putting it in the database however you like. Some Ideal Attributes of a Solution Causes no noticeable performance hit on the server being monitored Has a very high precision of measurement Does not store useless or redundant information Is easy to query (lends itself to gathering/displaying useful information) Lends itself to being graphed easily Is accurate Is elegant Primary Questions 1) What is a good design/method/scheme for triggering the storing of statistics? 2) What is a good database design for how to actually store the data? Example answers...that are sort of vague and lame... 1) I could, once per [fixed time interval], store a row of data with all the performance measurements I care about in each column of one big flat table indexed by timestamp and/or server. 2) I could have a daemon monitoring performance stuff I care about, and add a row whenever something changes (instead of at fixed time intervals) to a flat table as in #1. 3) I could trigger either as in #2, but I could store information about each aspect of performance that I'm measuring in separate tables, opening up the possibility of adding tons of rows for often-changing items, and few rows for seldom-changing items. Etc. In the end, I will implement something, even if it's some super-braindead approach I make up myself, but I'm betting there are some really smart people out there willing to share their experiences and bright ideas!

• Simulating mouse clicks on Mac OS X does not work for some applications.

  - by Thomi

  I'm writing an application for Mac OS X 10.6 and later in C++. One part of the application needs to simulate mouse movement and mouse clicks. I do this currently by posting CGEvent objects using CGEventPost(kCGHIDEventTap, event);. This works, for the most part - I can simulate mouse movement and clicks just fine, but it seems to fail in some areas. For example: In Mozilla Firefox and Safari, I can click on all the menus, but cannot click on a link within a website. When I try, the link is highlighted, but the browser never follows the link. However, I can right-click on a link, select "open link in new tab", and everything works as expected. Solved - creating the mouse event using CGEventCreateMouseEvent(...) makes the event work within web browser. I can click on the "Dashboard" icon to brink up the dashboard, but I cannot click on the "i" button on any of the dashboard widgets. Similarly, clicking on any of the search results from the spotlight search widget doesn't work either. This inconsistency is along application boundaries. What might be the cause?

• Is there a Scheduler/Calendar JS Widget library?

  - by Ravi Chhabra

  I am looking for some JavaScript based component to be used as a course scheduler which would be a cross between Google Calendar and the login time. I do not know if the right term for this is Course Scheduler but I shall describe this in more detail here. Course Scheduler The widget would be used to enter date and times of a course, as an example if I run a programming course 3 days a week on Mon, Tue and Wed every 7:00 am to 9:00am, 2 hours every day from 1st September to 30th November. I could answer various questions and the course data would be displayed in the calendar. It would also allow for non pattern based timings where each week is different from the other week etc. Question So would I end up creating something from scratch? Would it be sensible to use Google Calendar API for this? I did a Google search for some widgets, but I believe I need better keywords, as I could not find anything close to what I am looking for. Any tips? Commercial libraries would also work for me. Thanks.

• Autodiscovery for inclusion tags

  - by Ludwik Trammer

  The title may be a little confusing, but I don't know how else to call it. I would like to create a Django project with a large set of applications you could arbitrary turn on or off using INSTALLED_APPS option in settings.py (you would obviously also need to edit urls.py and run syncdb). After being turned on an app should be able to automatically: Register it's content in site-wide search. Luckily django-haystack has this built-in, so it's not a problem. Register cron jobs. django-cron does exactly that. Not a problem. Register a widget that should be displayed on the homepage. The homepage should include a list of boxes with widgets form different applications. I thought about inclusion tags, because you can put them anywhere on a page and they control both content and presentation. The problem is I don't know how to automatically get a list of inclusion tags provided by my applications, and display them one by one on a homepage. I need a way to register them somehow, and then display all registered tags.

• Is there a way to customize how the value for a custom Model Field is displayed in a template?

  - by Jordan Reiter

  I am storing dates as an integer field in the format YYYYMMDD, where month or day is optional. I have the following function for formatting the number: def flexibledateformat(value): import datetime, re try: value = str(int(value)) except: return None match = re.match(r'(\d{4})(\d\d)(\d\d)$',str(value)) if match: year_val, month_val, day_val = [int(v) for v in match.groups()] if day_val: return datetime.datetime.strftime(datetime.date(year_val,month_val,day_val),'%b %e, %Y') elif month_val: return datetime.datetime.strftime(datetime.date(year_val,month_val,1),'%B %Y') else: return str(year_val) Which results in the following outputs: >>> flexibledateformat(20100415) 'Apr 15, 2010' >>> flexibledateformat(20100400) 'April 2010' >>> flexibledateformat(20100000) '2010' So I'm wondering if there's a function I can add under the model field class that would automatically call flexibledateformat. So if there's a record r = DataRecord(name='foo',date=20100400) when processed in the form the value would be 20100400 but when output in a template using {{ r.date }} it shows up as "April 2010". Further clarification I do normally use datetime for storing date/time values. In this specific case, I need to record non-specific dates: "x happened in 2009", "y happened sometime in June 1996". The easiest way to do this while still preserving most of the functionality of a date field, including sorting and filtering, is by using an integer in the format of yyyymmdd. That is why I am using an IntegerField instead of a DateTimeField. This is what I would like to happen: I store what I call a "Flexible Date" in a FlexibleDateField as an integer with the format yyyymmdd. I render a form that includes a FlexibleDateField, and the value remains an integer so that functions necessary for validating it and rendering it in widgets work correctly. I call it in a template, as in {{ object.flexibledate }} and it is formatted according to the flexibledateformat rules: 20100416 - April 16, 2010; 20100400 - April 2010; 20100000 - 2010. This also applies when I'm not calling it directly, such as when it's used as a header in admin (http://example.org/admin/app_name/model_name/). I'm not aware if these specific things are possible.

• Java: Initializing a public static field in superclass that needs a different value in every subclas

  - by BinaryMuse

  Good evening, I am developing a set of Java classes so that a container class Box contains a List of a contained class Widget. A Widget needs to be able to specify relationships with other Widgets. I figured a good way to do this would be to do something like this: public abstract class Widget { public static class WidgetID { // implementation stolen from Google's GWT private static int nextHashCode; private final int index; public WidgetID() { index = ++nextHashCode; } public final int hashCode() { return index; } } public abstract WidgetID getWidgetID(); } so sublcasses of Widget could: public class BlueWidget extends Widget { public static final WidgetID WIDGETID = new WidgetID(); @Override public WidgetID getWidgetID() { return WIDGETID; } } Now, BlueWidget can do getBox().addWidgetRelationship(RelationshipTypes.SomeType, RedWidget.WIDGETID, and Box can iterate through it's list comparing the second parameter to iter.next().getWidgetID(). Now, all this works great so far. What I'm trying to do is keep from having to declare the public static final WidgetID WIDGETID in all the subclasses and implement it instead in the parent Widget class. The problem is, if I move that line of code into Widget, then every instance of a subclass of Widget appears to get the same static final WidgetID for their Subclassname.WIDGETID. However, making it non-static means I can no longer even call Subclassname.WIDGETID. So: how do I create a static WidgetID in the parent Widget class while ensuring it is different for every instance of Widget and subclasses of Widget? Or am I using the wrong tool for the job here? Thanks!

• Selectively allow unsafe html tags in Plone

  - by dhill

  I'm searching for a way to put widgets from several services (PicasaWeb, Yahoo Pipes, Delicious bookmarks, etc.) on the community site I host on Plone (currently 3.2.1). I'm looking for a way to allow a group of users to use dangerous html tags. There are some ways I see, but I don't know how to implement those. One would be changing safe_html for the pages editors own (1). Another would be to allow those tags on some subtree (2). And yet another finding an equivalent of "static text portlet" that would display in the middle panel (3). We could then use some of the composite products (I stumbled upon Collage and CMFContentPanels), to include the unsafe content on other sites. My site has been ridden by advert bots, so I don't want to remove the filtering all together. I don't have an easy (no false positives) way of checking which users are bots, so deploying captcha now wouldn't help either. The question is: How to implement any of those solutions? (I already asked that on plone mailing list without an answer, so I thought I would give it another try here.)

• asses resouces from another apk for widget(like theme apk)

  - by Diljeet

  asses resouces from another apk for widget(like theme apk) Hello i made a theme with drawables and strings, i can access the theme's resources by following commands String packagename="com....."; Resources res = context.getPackageManager().getResourcesForApplication(packagename); int strid = res.getIdentifier(packagename+":string/"+name, "string", packagename); int drawableid = res.getIdentifier(packagename+":drawable/"+name, "drawable", packagename); String name = res.getString(resid); Bitmap bmp = BitmapFactory.decodeResource(res, resid); //or Drawable dr=res.getDrawable(resid); I can get the drawables, but i don't know how to set the drawables in xml to a widget. I only can set setImageViewResource(int viewid, int resId); So i am asking that how to access xml resources from another apk and set widget drawables from it. I want to access a resource like this from another theme apk, but i can only access the drawable(so can't use it for widgets) <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:drawable="@drawable/wplayh" /> <item android:drawable="@drawable/wplay" /> </selector>

• Submit form with POST data in Android app

  - by datguywhowanders

  I've been searching the web for a way to do this for about a week now, and I just can't seem to figure it out. I'm trying to implement an app that my college can use to allow users to log in to various services on the campus with ease. The way it works currently is they go to an online portal, select which service they want, fill in their user name and pwd, and click login. The form data is sent via post (it includes several hidden values as well as just the user name and pwd) to the corresponding login script which then signs them in and loads the service. I've been trying to come at the problem in two ways. I first tried a WebView, but it doesn't seem to want to support all of the html that normally makes this form work. I get all of the elements I need, fields for user and pwd as well as a login button, but clicking the button doesn't do anything. I wondered if I needed to add an onclick handler for it, but I can't see how as the button is implemented in the html of the webview not using a separate android element. The other possibility was using the xml widgets to create the form in a nice relative layout, which seems to load faster and looks better on the android screen. I used EditText fields for the input, a spinner widget for the service select, and the button widget for the login. I know how to make the onclick and item select handlers for the button and spinner, respectively, but I can't figure out how to send that data via POST in an intent that would then launch a browser. I can do an intent with the action url, but can't get the POST data to feed into it. Anyone have any suggestions?

• Tablesorter Pager not working in Safari or Chrome

  - by Zendog74

  Hi all. I am building an app using the tablesorter plug-in and it's pager plug-in. Things work perfectly fine in Firefox and IE, but in Safari (4.0.4 on a PC) and Chrome () I get errors when it hits the following code that binds the tablesorter pager. I took the pager binding out and it worked, so something is going wrong somewhere in those three lines of code. var tableSel = calendarportlet.ut.createIdSelector(calendarportlet.addNamespace("eventListTable")); var pagerSel = calendarportlet.ut.createIdSelector(calendarportlet.addNamespace("pager")); jQuery(tableSel).tablesorter({ widthFixed: true, headers: { 0: {sorter: false} }, sortList:[[2,1],[1,0]], widgets: ['zebra'] }).tablesorterPager({ <-- error happens in here container: jQuery(pagerSel), positionFixed: false }); Also, the errors only happen in Safari and Chrome when prototype.js is loaded AFTER jQuery. If they are loaded before jQuery, it works fine. However, this is a portlet and it has to play nice with other portlets, so we don't want to modify the header and loading order of the js libs. Anyone have any ideas on how to fix this?

• How to check what goes wrong in $view->render with Zend Framework?

  - by koko

  Hi, I'm working on a CMS with Widgets. On my localhost the followong code works perfect, but I have no idea what I'm doing wrong ... The neede files exist, I think and I get no error message. As far as I can see, the error occurs in the one before last line of code and I get no error message. $view = new Zend_View(); $view->setScriptPath(APPLICATION_PATH . '/../public/websites/' .

• Open source libraries to design directed graphs

  - by Benjamin

  Hi all, I'm going to need to write a software that takes a list of persons and connects them together in a directed-graph-like manner. The GUI aspect of the whole project is very important. The graph must allow a lot of interaction. Such as selecting several people and hiding the others, moving them around. Additionally, the software will need to be able to provide other kind of GUI-features such as several tabs, text boxes etc. The application must be quite performant. As in, it must be able to handle hundreds if not thousands of widgets. Hence, I would like to know which open source libraries (at this point the programming language they are written in does not matter - I just want an overview of everything good that is out there) would allow me to develop such piece of software? What would you recommend? Thanks for that. Edit: Could you please also link to tutorials explaining how I could program a GUI that can interact with the generated graph? For example mouse events.

• should i advocate migrating from access to (my)sql

  - by HotOil

  Hi: We have a windows MFC app that is written against an access database on a company server. The db is not that big: 19 MB. There are at most 2-3 users accessing it at any one time. It is used in a factory environment where access speed (or lack thereof) over the intranet becomes noticeable as it is part of the manufacturing time for our widgets. The scenario is this: as each widget is completed, it gets a record in the db.. by the end of the year, the db is larger and searching for a record takes longer and longer. The solution so far has been to manually move older records to an archival table about once a year. We are reworking other portions of this app right now, and it would be a good time to move to another db if we are going to do it. It is my understanding that if we were using sql, the search time would not go up as the table gets bigger because the entire .mdb does not have to be sent over the network each time. Is this correct? Does anyone have any insight about whether it could be worth it to go to the trouble (time and money) of migrating to a new db, or should I just add more functionality to the application we have now, and maybe automatically purge the older records from time to time, and add additional facilities to the app to get at the older records when needed? Thanks for any wisdom you can share..

• Sorting and Pagination does not work after I build a custom keyword search that is build using relat

  - by Roland

  I recently started to build a custom keyword search using Yii 1.1.x The search works 100%. But as soon as I sort the columns and use pagination in the admin view the search gets lost and all results are shown. So with otherwords it's not filtering so that only the search results show. Somehow it resets it. In my controller my code looks as follows $builder=Messages::model()->getCommandBuilder(); //Table1 Columns $columns1=array('0'=>'id','1'=>'to','2'=>'from','3'=>'message','4'=>'error_code','5'=>'date_send'); //Table 2 Columns $columns2=array('0'=>'username'); //building the Keywords $keywords = explode(' ',$_REQUEST['search']); $count=0; foreach($keywords as $key){ $kw[$count]=$key; ++$count; } $keywords=$kw; $condition1=$builder->createSearchCondition(Messages::model()->tableName(),$columns1,$keywords,$prefix='t.'); $condition2=$builder->createSearchCondition(Users::model()->tableName(),$columns2,$keywords); $condition = substr($condition1,0,-1) . " OR ".substr($condition2,1); $condition = str_replace('AND','OR',$condition); $dataProvider=new CActiveDataProvider('Messages', array( 'pagination'=>array( 'pageSize'=>self::PAGE_SIZE, ), 'criteria'=>array( 'with'=>'users', 'together'=>true, 'joinType'=>'LEFT JOIN', 'condition'=>$condition, ), 'sort'=>$sort, )); $this->render('admin',array( 'dataProvider'=>$dataProvider,'keywords'=>implode(' ',$keywords),'sort'=>$sort )); and my view looks like this $this->widget('zii.widgets.grid.CGridView', array( 'dataProvider'=>$dataProvider, 'columns'=>array( 'id', array( 'name'=>'user_id', 'value'=>'CHtml::encode(Users::model()->getReseller($data->user_id))', 'visible'=>Yii::app()->user->checkAccess('poweradministrator') ), 'to', 'from', 'message', /* 'date_send', */ array( 'name'=>'error_code', 'value'=>'CHtml::encode($data->status($data->error_code))', ), array( 'class'=>'CButtonColumn', 'template'=>'{view} {delete}', ), ), )); I really do not know what do do anymore since I'm terribly lost, any help will be hihsly appreciated

• 'C++ object destroyed' in QComboBox descendant editor in delegate

  - by Max

  Hi, all! I have modified combobox to hold colors, using QtColorCombo (http://qt.nokia.com/products/appdev/add-on-products/catalog/4/Widgets/qtcolorcombobox) as howto for the 'more...' button implementation details. It works fine in C++ and in PyQt on linux, but I get 'underlying C++ object was destroyed' when use this control in PyQt on Windows. It seels like the error happens when: ... # in constructor: self.activated.connect(self._emitActivatedColor) ... def _emitActivatedColor(self, index): if self._colorDialogEnabled and index == self.colorCount(): print '!!!!!!!!!

• How do I DRY up business logic between sever-side Ruby and client-side Javascript?

  - by James A. Rosen

  I have a Widget model with inheritance (I'm using Single-Table Inheritance, but it's equally valid for Class-per-Table). Some of the subclasses require a particular field; others do not. class Widget < ActiveRecord ALL_WIDGET_TYPES = [FooWidget, BarWidget, BazWidget] end class FooWidget < Widget validates_presence_of :color end class BarWidget < Widget # no color field end class BazWidget < Widget validates_presence_of :color end I'm building a "New Widget" form (app/views/widgets/new.html.erb) and would like to dynamically show/hide the color field based on a <select> for widget_type. <% form_for @widget do |f| %> <%= f.select :type, Widget::ALL_WIDGET_TYPES %> <div class='hiddenUnlessWidgetTypeIsFooOrBaz'> <%= f.label :color %> <%= f.text_field :color %> </div> <% end %> I can easily write some jQuery to watch for onChange events on widget_type, but that would mean putting some sort of WidgetTypesThatRequireColor constant in my Javascript. Easy enough to do manually, but it is likely to get disconnected from the Widget model classes. I would prefer not to output Javascript directly in my view, though I have considered using content_for(:js) and have a yield :js in my template footer. Any better ideas?

• How to get a unique WindowRef in a dockable Qt application on Mac

  - by Robin

  How do I get a unique WindowRef from a Qt application that includes docked windows on the Mac? My code boils down to: int main(int argc, char* argv[]) { QApplication* qtApp = new QApplication(argc, argv); MyQMainWindow mainwin; mainwin.show(); } class MyQMainWindow : public QMainWindow { //... QDockWidget* mDock; MyQWidget* mDrawArea; QStackedWidget* mCentralStack; }; MyQMainWindow::MyQMainWindow() { mDock = new QDockWidget(tr("Docked Widget"), this); mDock->setMaximumWidth(180); //... addDockWidget(Qt::RightDockWidgetArea, mDock); mDrawArea = new MyQWidget(this); mCentralStack = new QStackedWidget(); mCentralStack->addWidget(mDrawArea); // Other widgets added to stack in production code. setCentralWidget(mCentralStack); //... } (Apologies if the above isn't syntactically correct, it's just easier to illustrate than to describe.) I added the following temporary code at the end of the above constructor: HIViewRef view1 = (HIViewRef) mDrawArea->winId(); HIViewRef view2 = (HIViewRef) mDock->winId(); WindowRef win1 = HIViewGetWindow(view1); WindowRef win2 = HIViewGetWindow(view2); My problem is that view1 and view2 are different, but win1 and win2 are the same! I tried the following equivalent on Windows: HWND win1 = (HWND)(mCentralDrawArea->winId()); HWND win2 = (HWND)(mDock1->winId()); This time win1 and win2 are different. I need the window handle to pass on to a 3rd party SDK so that it can draw into the central area only. BTW, I appreciate that the winId() method comes with lots of portability warnings, but a substantial refactor is out of the question for me. The same goes for using Carbon instead of Cocoa. Thanks.

• How to update a Widget dynamically (Not waiting 30 min for onUpdate to be called)?

  - by Donal Rafferty

  I am currently learning about widgets in Android. I want to create a WIFI widget that will display the SSID, the RSSI (Signal) level. But I also want to be able to send it data from a service I am running that calculates the Quality of Sound over wifi. Here is what I have after some reading and a quick tutorial: public class WlanWidget extends AppWidgetProvider{ RemoteViews remoteViews; AppWidgetManager appWidgetManager; ComponentName thisWidget; WifiManager wifiManager; public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { Timer timer = new Timer(); timer.scheduleAtFixedRate(new WlanTimer(context, appWidgetManager), 1, 10000); } private class WlanTimer extends TimerTask{ RemoteViews remoteViews; AppWidgetManager appWidgetManager; ComponentName thisWidget; public WlanTimer(Context context, AppWidgetManager appWidgetManager) { this.appWidgetManager = appWidgetManager; remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); thisWidget = new ComponentName(context, WlanWidget.class); wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); } @Override public void run() { remoteViews.setTextViewText(R.id.widget_textview, wifiManager.getConnectionInfo().getSSID()); appWidgetManager.updateAppWidget(thisWidget, remoteViews); } } The above seems to work ok, it updates the SSID on the widget every 10 seconds. However what is the most efficent way to get the information from my service that will be already running to update periodically on my widget? Also is there a better approach to updating the the widget rather than using a timer and timertask? (Avoid polling) UPDATE As per Karan's suggestion I have added the following code in my Service: RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); ComponentName thisWidget = new ComponentName( context, WlanWidget.class ); remoteViews.setTextViewText(R.id.widget_QCLevel, " " + qcPercentage); AppWidgetManager.getInstance( context ).updateAppWidget( thisWidget, remoteViews ); This gets run everytime the RSSI level changes but it still never updates the TextView on my widget, any ideas why?

• What is the best free cross-platform OpenGL GUI library for a video game?

  - by Jim Buck

  It must come with source. I've looked at these which look semi-promising: glgooey, guichan, and cegui. I've come across others that look more Windows-y than game-y, but that's not the direction I am looking to go in. I would like some simple functionality of typical controls (lists, dropdown box, etc.) but with support for graphical widgets that you would normally find in game frontends. Mouse clicking, dragging, dropping, etc. and sound effect hooks would be nice. (These libs often leave hooks for the external system to tell it when/where mouse events are occurring.) It would get rendered on top of what my own 3D engine is rendering for the game, so it must be able to play nicely with rendering code outside of the lib. The best criteria is whether or not a reasonable 2D game could be implemented just with the GUI library and minimal glue code. (By glue code, I mean init code, hooking up the mouse, and game logic.) I am creating a 3D game, but this criteria gives a pretty solid idea of what level of interactivity I would like in the GUI.

• Using struts 2 with no tags

  - by WannaAsk

  Hi everyone, I wonder if you could guide me on this struts issue - I feel hopeless on this... I am working on migrating our web application to a Struts 2 portlet (I'm using Struts 2.1.8). The thing is, I am forced to avoid struts tags because our application relies on Dijit widgets, which are omitted when using struts tags. So now I should implement the <s:form tag using scriptlets. My question is: how you would suggest I imitate the way struts handles the "action" attribute? Right now it appears I should: Create a regular html form in my jsp. Get/create the ActionConfig object during onsubmit and set on it values which match my desired destination: class+method+result jsp. Execute the action I set in 2. Would you recommend this? If so - is ActionConfig obtained from the session? Can I initiate an action execution from ActionConfig? (Aletrnatively... generating an action url using struts' form.vm file - what do you say?) I would appreciate any help on this - Thanks a lot in advance!!!
