How to set up a slider in QTextEdit object from Framework'a Qt 4.7?

Question

Qt

There is an instance of the QTextEdit class:

QTextEdit *info2 = new QTextEdit;
info2->setReadOnly(true);
info2->setMinimumHeight(300);
info2->setAlignment(Qt::AlignCenter);

I sequentially load information from the *.txt file into it:

QString str;
QFile LicenseFile("E:/Qt/License.txt");
if (!LicenseFile.open(QIODevice::ReadOnly | QIODevice::Text))
return;
QTextStream in(&LicenseFile);
while (!in.atEnd())
{ str = in.readLine();
info2->append(str);}
LicenseFile.close();

Question: what method should be called so that the text block slider at the moment the window is opened is not scrolled to the end of the QTextEdit window.

Answer 1

The fact is that QTextEdit has automatic scrolling control so that the cursor is always visible (perhaps for something else). Cursor control methods will help you, for example:

edit->moveCursor (QTextCursor::Start); //или QTextCursor::End
edit->ensureCursorVisible() ;

If cursors are needed for other purposes, then you have to think about it. Although the question is well googled on English forums, so you can get out.

Answer 2

If I'm not mistaken, it's done like this:

QScrollBar* bar = info2->verticalScrollBar();
bar->setValue(bar->minimum());
