move qTextBrowser to Home Position

[klaus1111]

I have the folling code: (textBrowser is a QTextBrowser)


textBrowser->clear();
textBrowser->append("String with 100 lines of text");
textBrowser->textCursor().movePosition(QTextCursor::Start);
textBrowser->ensureCursorVisible();

I thought this would make the beginning of the text visible for the user. But unfortunatly the cursor rest at the end of the text ( textBroser->textCursor().atEnd() returns true ).

I tried a work around with setting an named anchor at the beginning of the test, which works fine - but my app continues to write at the end. If I move to the beginning of the text with the keyboard pressing <ctrl+home> the windows stays very nice at the beginning - the anchor is some pixels lower, and the window continues to scroll.

now - how to move the window to the same state as <ctrl+home> does?

Thanks for your time,
Klaus

It doesn't work, because you operate on a copy of the cursor.


QTextCursor QTextEdit::textCursor () const
Returns a copy of the QTextCursor that represents the currently visible cursor. Note that changes on the returned cursor do not affect QTextEdit's cursor; use setTextCursor() to update the visible cursor.
See also setTextCursor().

yes - after your posting I must say, that it is clearly written in the documentation, which I have read at least 10 times before posting here. Funny - but sometimes you don't see what you see...

On the other hand - the behaviour is not 100% equal to the keyboard. When I move with the keyboard <ctrl+home> to the top, the textbrowser rest there, even if lines are appended to the end (what would be nice for my app in the moment). When I move with the "program" cursor, it now moves up, but in the moment where I append something the windows switchs back to the end. Does anybody has an idea about that?

Do you use QTextEdit::append() for this?

Maybe you should use another cursor?

QTextCursor cursor( _ui.textEdit->textCursor() );
cursor.movePosition( QTextCursor::End );
cursor.insertText( "xxx" );
