qtextcursor setposition doesn't work

[doc_symbiosis]

But the cursor is set to -1 when no match is found by the find method in the findslot:

void FindWidget::slotFind()
{
    QTextCursor cursor = mTextpage->textCursor();
 
    if (cursor.anchor() == -1) {
        cursor = mTextpage->document()->find(findEdit->text(), cursor, QTextDocument::FindCaseSensitively);
    } else {
        cursor = mTextpage->document()->find(findEdit->text(), cursor.anchor(), QTextDocument::FindCaseSensitively);
    }
    mTextpage->setTextCursor(cursor);
    this->setBackground();
}

void FindWidget::slotFind()
{
    QTextCursor cursor = mTextpage->textCursor();

    if (cursor.anchor() == -1) {
        cursor = mTextpage->document()->find(findEdit->text(), cursor, QTextDocument::FindCaseSensitively);
    } else {
        cursor = mTextpage->document()->find(findEdit->text(), cursor.anchor(), QTextDocument::FindCaseSensitively);
    }
    mTextpage->setTextCursor(cursor);
    this->setBackground();
}

To copy to clipboard, switch view to plain text mode 

So my thought was, to set the position of the cursor in the slotClose to 0, if it is -1. But this doesn't work and I definetly don't understand why.

So don't put it there! Just don't call setTextCursor() if you don't want to.

It doesn't work because the cursor is invalid. It's probably even not tied to your document. Use the code I gave you in my previous post instead.
