QTextEdit->ensureCursorVisible() with QScrollArea

[tux1124]

Hi,

In my program, I have a QWidget that contains a QScrollArea which itself contains two QTextEdit.
I just want the QTextCursor remains visible, so the user sees what he's typing.
I know there is a method "ensureCursorVisible()" in QTextEdit but, strangely, it does not work with a QScrollArea.
I'm using this code for the moment:
@layout_vertical = new QVBoxLayout;
QTextEdit *textEdit = new QTextEdit;
scrollArea = new QScrollArea;
scrollArea->setAlignment(Qt::AlignHCenter);
widget = new QWidget;
layout_vertical->addWidget(document_onglet, 0, Qt::AlignHCenter);
widget->setLayout(layout_vertical);
MyQMdiSubWindow->setWidget(scrollArea);
textEdit->setMaximumHeight(1500);
textEdit->setMinimumHeight(1500);
textEdit->setMinimumWidth(800);
textEdit->setMaximumWidth(800);
textEdit->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
textEdit->ensureCursorVisible();
QTextEdit *o2 = new QTextEdit;
o2->setMaximumHeight(1500);
o2->setMinimumHeight(1500);
o2->setMinimumWidth(800);
o2->setMaximumWidth(800);
layout_vertical->addWidget(o2, 0, Qt::AlignHCenter);
scrollArea->setWidget(widget); @

Everything is OK except except that the QScrollAreanot move when the cursor disappears "under the program."
So, how can I force the cursor to remain visible?

Thanks :D
