    \class HbMessageBox

    \brief HbMessageBox is a convenience modal dialog class. HbMessageBox can be used to launch a information,question,warning or any other 

    general messages.

    Using HbMessageBox, the following dialogs can be created:

    <b>Information:</b> a statement to the user to which they may respond by acknowledging the information ('Ok').<br>

    <b>Question:</b> a query to the user requiring a response. User needs to select between two alternatives, the positive or negative (For example: 'Delete Mailbox?' 'Yes'/'No').<br>

    <b>Warning:</b> a statement to the user to which they may respond by acknowledging the warning ('OK').<br>

    <b>None:</b> Any general messages to which user responds. 

    By default, Message box launches a None dialog which can contain a text, an icon and action buttons

    Default properties for the MessageBox (warning, information and question dialogs) are:

    Description text: Text shown to the user as information. The amount of text rows is not limited, but after five rows the text starts scrolling.

    Icon: Default icons are available for each dialog type using the MessageBox template. Changing the default icons is not recommended.

    Action button : One action button ("Ok") for all the types.

    All the four dialogs(information, warning, question and none) supported by MessageBox are by default modal in nature, with

    a dismiss policy of NoDismiss, timeout policy of NoTimeout, and with a BackgroundFade property on.

    Example code for launching MessageBox using static convenience functions:

    \code

    //Information MessageBox

    HbMessageBox::information("The file is deleted",0,0,HbMessageBox::Ok);

    //Warning MessageBox

    HbMessageBox::warning("This will change the name",0,0,HbMessageBox::Ok);

    //Question MessageBox

     HbMessageBox::question("Do you want to delete the file ?", this, SLOT(onDialogClose(int)),HbMessageBox::Yes |HbMessageBox::No );

    \endcode

    Example code to show an information messagebox:

    \code

    HbMessageBox *box = new HbMessageBox("This is a general note.");

    box->setAttribute(Qt::WA_DeleteOnClose);

    box->open();

    \endcode

    Example code to show a question messagebox with a return value based action

    \code

    HbMessageBox *box = new HbMessageBox(HbMessageBox::MessageTypeQuestion);

    box->setText("Delete file IC0002 ? ");

    box->setAttribute(Qt::WA_DeleteOnClose);

    box->setStandardButtons(HbMessageBox::Yes | HbMessageBox::No);

    box->open(this,SLOT(onDialogClosed(int)));

    //Slot implementation

    void MessageBoxView::onDialogClosed(int action)

    {

         if (action == HbMessageBox::Yes) {

          //User Clicked Yes//

          //Delete the file//

         }

         else if (action == HbMessageBox::No) {

          //User Clicked No//

          //do not delete the file//

         }

    }

    \endcode     

    Example code to show a question messagebox using static API

     \code

     HbMessageBox::question("Delete file IC0002 ? ",this,SLOT(onDialogClosed(int)),HbMessageBox::Yes | HbMessageBox::No);  

     // Here the SLOT implementation is same as above

     \endcode     

    \enum HbMessageBox::MessageBoxType

    \value \b MessageTypeNone creates a modal dialog, which by default will have one OK button 

        for the user to dismiss the dialog.

    \value \b MessageTypeWarning creates a simple modal dialog with a warning icon and a description text. 

        This Dialog by default will have one Ok button, for the user to dismiss the dialog. 

    \value \b MessageTypeWarning creates a simple modal dialog with a information icon and a description text. 

        This Dialog by default will have one Ok button, for the user to dismiss the dialog. 

     \value \b MessageTypeQuestion creates a simple modal dialog with a question icon and a description text. 

        This Dialog by default will have one Ok button, for the user to dismiss the dialog.
