Symbian如何使用等待对话框

一、在View的头文件中添加

1、

#include // for MProgressDialogCallback

2、

class CAknWaitDialog;

3、

class CContainerView : public CAknView

,public MMyEncryptAndDecryptObserver

,public MProgressDialogCallback

4、

private:

void StartWaitDialog(const TDesC& aLabel);

void StopWaitDialog();

void DialogDismissedL(TInt aButtonId);

5、

private:

CAknWaitDialog* iWaitDialog;

二、在View的实现文件中添加

1、

#include // for CAknWaitDialog

2、

void CContainerView::DialogDismissedL(TInt aButtonId)

{

if (-1 == aButtonId)

{//用户选择取消

iMyEncryptAndDecrypt->Cancel();

}

}

3、

void CContainerView::StartWaitDialog(const TDesC& aLabel)

{

if(iWaitDialog)

{

delete iWaitDialog;

iWaitDialog = NULL;

}

// For the wait dialog

iWaitDialog = new (ELeave) CAknWaitDialog(

REINTERPRET_CAST(CEikDialog**, &iWaitDialog));

iWaitDialog->SetCallback(this);

iWaitDialog->SetTextL(aLabel);

iWaitDialog->ExecuteLD(R_GENERAL_WAIT_NOTE);

}

4、

void CContainerView::StopWaitDialog()

{

// For wait dialog

iWaitDialog->ProcessFinishedL();

iWaitDialog = NULL;

}

三、添加资源

1、

RESOURCE DIALOG r_general_wait_note

{

flags = EAknWaitNoteFlags;

buttons = R_AVKON_SOFTKEYS_CANCEL;

items =

{

DLG_LINE
