| class CAknProgressDialog : public CAknNoteDialog |
A note dialog with a timer. Display the note only if the process is at least 1 second long in order to avoid a note quickly flashing on the screen. Display the note for at least 1.5 seconds (even if the client process is shorter that this). The client can specify an initial delay when displaying the note. Timer events are used for displaying and dismissing the dialog. The client can set the progress by specifying the values in the constructors provided.
Fixed process length
iProgressDialog = new(ELeave) CAknProgressDialog (model->FinalValue(),model->Increment(), model->Interval(), (REINTERPRET_CAST(CEikDialog**,&iProgressDialog))); iProgressDialog->ExecuteLD(R_PROGRESS_NOTE);
Variable process length
iProgressDialog = new(ELeave) CAknProgressDialog ( (REINTERPRET_CAST(CEikDialog**,&iProgressDialog))); iProgressInfo = iProgressDialog-> GetProgressInfoL() ; iProgressInfo->SetFinalValue(model->FinalValue()); iProgressDialog->ExecuteLD(R_PROGRESS_NOTE);
// Incrementing progress of the process: iProgressInfo->IncrementAndDraw(model->Increment());
// Process finished iProgressDialog-> ProcessFinishedL() ; // deletes the dialog
Variable process length, modal dialog
Set following flags in resources: EEikDialogFlagWait and EAknProgressNoteFlags
iProgressDialog = new(ELeave) CAknProgressDialog ( (REINTERPRET_CAST(CEikDialog**,&iProgressDialog))); iProgressInfo = iProgressDialog-> GetProgressInfoL() ; iProgressInfo->SetFinalValue(model->FinalValue()); iProgressInfo->SetTone( CAknNoteDialog::EConfirmationTone ); iProgressDialog->ExecuteLD(R_PROGRESS_NOTE);
// Incrementing progress of the process: iProgressInfo->IncrementAndDraw(model->Increment());
// Process finished iProgressDialog-> ProcessFinishedL() ; // deletes the dialog
Setting label dynamically
iProgressDialog = new(ELeave) CAknProgressDialog ( (REINTERPRET_CAST(CEikDialog**,&iProgressDialog))); iProgressDialog->PrepareLC(R_PROGRESS_NOTE); iProgressDialog->SetTextL(_L("Hello AVKON!")); iProgressDialog-> RunLD() ;
Inherit from pure virtual class MProgressDialogCallback
Implement DialogDismissedL
Call CAknProgressDialog->SetCallback(this);
Or make your dialog modal. If the dialog is used as a modal, RunLD returns 0 if the dialog is dismissed and EAknSoftkeyDone if not.
Always set EEikDialogFlagNotifyEsc. (or use preset avkon dialog resource flag, i.e. EAknProgressNoteFlags).
To make a dialog modal use EEikDialogFlagWait
Note! If aVisibilityDelayOff is set to ETrue in constructor the dialog will be visible immediality. This should only be used in cases where the process lasts ALWAYS atleast 1.5 seconds.
