label with background?

Need to put a bitmap in your label control?

 //create an image
 Image img;
 r = img.Construct();
 TryReturn(r==E_SUCCESS ,r, GetErrorMessage(r));

        //create a bitmap (background)
 __pBitmapBg = img.DecodeN(bgPopupPath,BITMAP_PIXEL_FORMAT_ARGB8888);
 TryReturn(GetLastResult()==E_SUCCESS,GetLastResult(), 
 GetErrorMessage(GetLastResult()));

        //get label control
 __pLabelMainTitle = static_cast(GetControl(L"IDC_LABEL1"));
 if(null!=__pLabelMainTitle){
//create a bitmap to the label
  __pBitmapMainLabel = new Bitmap();
//we need to construct the background with label size (getbounds())
  __pBitmapMainLabel->Construct(*__pBitmapBg,
                         __pLabelMainTitle->GetBounds());
//set the label background (that was cut from the background)
  __pLabelMainTitle->SetBackgroundBitmap(*__pBitmapMainLabel);

popup

According to BadaDev, Samsung Apps is not accepting applications which uses MessageBox, for three reasons:

1. Message box closes when user touchs out side it.
2. The button’s captions are in device’s language and not in the application’s language.
3. The Home hard button does not works while the MessageBox has focus.

All three issues relatives to MessageBox itself, but Samsung App Review Team does not care about it.

So, let's see how to work with Popup!

The Popup is an implementation of Window. It can have controls such as Buttons, Labels, and so on. However, the Popup cannot attach some controls such as Frames, MessageBoxes, Forms and another instance of a Popup.

The Popup is displayed in the center of top screen. The Show() method is responsible for displaying the popup and its children.

Example :



Now, lets see how to create a Popup:
Insert a Resource

Select Popup resolution

Create your popup... (UI - controls)

Now, you must create a Popup .cpp and .h file, to get Popup reference, as shown below:

Note that this popup example has two buttons and one label, as presented in .cpp and .h code.


To see your popup... you must create an instance and call setshowstate and show functions, as shown below:

YourClass.cpp

result r = E_SUCCESS;
__pPopup = new Popup();
  if(!__pPopup->Initialize()){
     r = E_FAILURE;
  }

r = __pPopup->SetShowState(true);
TryCatch(r == E_SUCCESS, , GetErrorMessage(r));
r = __pPopup->Show();
TryCatch(r == E_SUCCESS, , GetErrorMessage(r));

timer

Today we will see how to use Osp::Base::Runtime::Timer

This class can activate the timer and notify the listeners.
This timer class is not a periodic timer, only a one-shot timer. If you want to carry out periodic tasks, you must start it again after it has fired.

It's easy to use Timers in your app... lets see:

You must extend and construct your Timer

Extend (.h):

public Osp::Base::Runtime::ITimerEventListener

Construct(.cpp):

    __pTimer = new Timer();
    r = __pTimer->Construct(*this);
    r = __pTimer->Start(1000);

Implement OnTimerExpired (to start again your Timer), as shown below:

void
MyApp::OnTimerExpired(Timer& timer)
{

    ...

    timer.Start(1000);
}

Full example:

class MyApp
    : public ITimerEventListener
{
   ...
public:
    result InitTimer();
public:
    void OnTimerExpired(Timer& timer);
};

void
MyApp::OnTimerExpired(Timer& timer)
{

    ...

    timer.Start(1000);
}


result
MyApp::InitTimer()
{
    result r = E_SUCCESS;

    __pTimer = new Timer;

    r = __pTimer->Construct(*this);
    if (IsFailed(r))
    {
        goto CATCH;
    }

    __pTimer->Start(1000);
    if (IsFailed(r))
    {
        goto CATCH;
    }

    return r;
CATCH:
    return r;
}

A real example - implementing a bada Chronometer:
Construct:

    keepRunning = true;
    //get actual time and set as initial time when form is loaded.
    SystemTime::GetTicks(initialTime);
    __pTimer = new Timer();
    r = __pTimer->Construct(*this);
    r = __pTimer->Start(1000);

void
MyApp::Cronometer(){
 completeTime = "00:00:00";
 int diff, hour, minutes, seconds;
    String hourTxt, minutesTxt, secondsTxt;
 if(keepRunning){
  SystemTime::GetTicks(currentTime);
                //get actual time to make diff with initial time
  diff = (currentTime - initialTime);

  hour = Math::Floor((diff/1000)/60/60);
  minutes = Math::Floor((diff/1000)/60);
  seconds = Math::Floor((diff/1000)%60);
  if (seconds <= 9){
   secondsTxt = "0" + LongLong::ToString(seconds);
  }else if(seconds == 60){
   secondsTxt = "00";
   minutes++;
  }else{
   secondsTxt = LongLong::ToString(seconds%60);
  }

  if (minutes <= 9){
   minutesTxt = "0" + LongLong::ToString(minutes);
  }else if(minutes == 60){
   minutesTxt = "00";
   hour++;
  }else{
   minutesTxt = LongLong::ToString(minutes%60);
  }

  if (hour <= 9){
   hourTxt = "0" + LongLong::ToString(hour);
  }else if(hour == 24){
   hourTxt = "00";
  }else{
   hourTxt = LongLong::ToString(hour%24);
  }

  completeTime = hourTxt + ":"+ minutesTxt + ":"+ secondsTxt;

  Label *lblChrono = static_cast(GetControl(L"IDC_CHRONO"));
  if (null != lblChrono){
   lblChrono->SetText(completeTime);
   lblChrono->RequestRedraw(true);
  }

 }
    return;
}

void
MyApp::OnTimerExpired (Osp::Base::Runtime::Timer &timer)
{
 result r = E_SUCCESS;
        //call crhonometer to update label with time
 Cronometer();
        //start again - 1second period
 __pTimer->Start(1000);
 TryCatch(r == E_SUCCESS, , GetErrorMessage(r));
 return;

 CATCH:
  SetLastResult(r);
  return;

registry

Osp::Io::Registry Class Reference

This class provides a mechanism to access the registry file. Registry consists of several sections and each section can have several entries, but only to a single depth. An entry consists of a name-value pair. The entry name must be unique inside the same section. The entry value must be one of the following data types: int, double, float, String, UuId, ByteBuffer.

Registry is an easy way to persist data.

To persist your data, you must create a section and add a value, as shown below:

//Osp::Io::Registry::Registry(void)  
Osp::Io::Registry* pReg = new Osp::Io::Registry();
String regPath(L"regTest.ini");
result r = pReg->Construct(regPath, true);
TryCatch(r == E_SUCCESS, , "Failed to get a valid Registry. %s", 
GetErrorMessage(r));

//create a section (data types: int, double, float, String, 
//UuId, ByteBuffer)
r = pReg->AddSection(section);
TryCatch(r == E_SUCCESS, , "Failed to add the record section. %s",  
   GetErrorMessage(r));

//add a value to created section
//result AddValue (const Osp::Base::String §ionName, 
//const Osp::Base::String &entryName, 
//const Osp::Base::String &value)
//example: entryRecord = key, record = value
r = pReg->AddValue(section, entryRecord, record);
TryCatch(r == E_SUCCESS, , "Failed to add the record entry. %s", 
   GetErrorMessage(r));

//Writes the current contents of a registry in memory to 
//the non-volatile storage.
r = pReg->Flush();
TryCatch(r == E_SUCCESS, , "Failed to save registry changes. %s", 
   GetErrorMessage(r));
}

return;

CATCH:
SetLastResult(r);
if(pReg != null){
 delete pReg;
 pReg = null;
}

If you need to recover registered data:

//result  GetValue (const Osp::Base::String §ionName, 
//const Osp::Base::String &entryName, 
//Osp::Base::ByteBuffer &retVal) const

//result  GetValue (const Osp::Base::String §ionName, 
//const Osp::Base::String &entryName, 
//Osp::Base::UuId &retVal) const

//result  GetValue (const Osp::Base::String §ionName, 
//const Osp::Base::String &entryName, 
//Osp::Base::String &retVal) const

//result  GetValue (const Osp::Base::String §ionName, 
//const Osp::Base::String &entryName, float &retVal) const

//result  GetValue (const Osp::Base::String §ionName, 
//const Osp::Base::String &entryName, double &retVal) const

//result  GetValue (const Osp::Base::String §ionName, 
//const Osp::Base::String &entryName, int &retVal) const  
r = pReg->GetValue(section, key, value);
TryCatch(r == E_SUCCESS, , "Failed to get the record from 
the registry. %s", GetErrorMessage(r));

If you need to check if a section already exists:

bool
RegistryUtils::ContainsSection(Osp::Io::Registry& reg, 
Osp::Base::String& section)
{
 bool containsKey = false;
 Osp::Base::Collection::IList* pList = reg.GetAllSectionNamesN();
 Osp::Base::String* pSection = null;
 for(int index = 0; index < pList->GetCount(); index++)
 {
  pSection = (Osp::Base::String*)pList->GetAt(index);
  if(section.Equals(*(pSection), false))
  {
   containsKey = true;
   break;
  }
 }

If you need more info (API, code examples, ...), try Osp::Io::Registry Class Reference.

You can see registry file in: \Model\WaveWQ_LP1\Simulator\FS\Win32FS\Osp\Applications\ or Wave_LP1 in case of 400x800 device resolution.

bada i18n

Today we'll learn how to internationalize our bada apps.

i18n = internationalization - means of adapting computer software to different languages, regional differences and technical requirements of a target market. Internationalization is the process of designing a software application so that it can be adapted to various languages and regions without engineering changes. The terms are frequently abbreviated to the numeronyms i18n (where 18 stands for the number of letters between the first i and last n in internationalization, a usage coined at DEC in the 1970s or 80s).

8 steps to internationalize our bada apps:


Figure 1. Resource view: Double click in String table (as shown)


Figure 2. String view will be opened


Figure 3. Right click and choose Language Setting. Here you'll select the languages that your app will give support.


Figure 4. Add the languages that your app will give support


Figure 5. String table view will be updated with selected languages


Figure 6. Right click and choose "insert" to fill the table with internationalized content. I suggest you to use IDs with some pattern name. Example: IDS_CLASSNAME_VARIABLENAME


Figure 7. String table with a content example


Figure 8. You can just associate the contents, created in String tables, with any control (labels, buttons, ...)

If you need to internationalize any text that will not be constructed directly in any Form or Popup, you must insert the ID and content in String table and you can associate the created content to any control through code, as shown below:

...
//get controls
Label *lblContent = static_cast(GetControl(L"IDC_LABEL2CONTENT"));
Label *lblTitle = static_cast(GetControl(L"IDC_LABEL2MAINTITLE"));
Application* appStep = Application::GetInstance();
result r;
if(null!=lblContent && null!=lblTitle){
//get the string associated with an ID (String table) and 
//save into titleTxt var
r = appStep->GetAppResource()-> 
    GetString(L"IDS_FORM2SCREENLBL_OBST_TITLE",titleTxt);
TryCatch(r == E_SUCCESS, , "GetAppResource is failed");
//set the internationalized text from String table to Label.
lblTitle->SetText(titleTxt);
lblTitle->RequestRedraw(true);
r = appStep->GetAppResource()->
    GetString(L"IDS_FORM2SCREENLBL_OBST_CONTENT",contentTxt);
TryCatch(r == E_SUCCESS, , "GetAppResource is failed");
lblContent->SetText(contentTxt);
lblContent->RequestRedraw(true);
...

You can change emulator language and test your bada i18n...
