How can I move the cursor to the beginning of the CEikRichTextEditor

Hello,

I created an instance of CEikRichTextEditor. I put some texts into this editor. But the cursor is always at the end of the content.

I hope it goes to the beginning of the content when the content changes every time.

iOutputRichText->HandleTextChangedL();

iOutputRichText->SetCursorPosL(1, ETrue);
iOutputRichText->SetTextL(&output);
this->DrawDeferred();

I use the function SetCursorPosL(), but it seems that it does not work.

Please help me.
