[SOLVED] Cursor behavior in QTextEdit after applying stylesheet

hryqt

Dear all,

I used FocusInEvent and FocusOutEvent to change background color of QTextEdit using stylesheet.

If I don't change the background color, the cursor behaves correctly (appear in QTextEdit when I click it, and gone when it lost focus).

However, when I change background color (using stylesheet), the cursor remain appear (and blinking) in QTextEdit, so that when I click different QTextEdit, the cursor will appear (and blinking) in two QTextEdit.

I tried to set cursor width to 0 to make it disappear after QTextEdit lost focus, however I couldn't restore back the cursor. I set the width to 1 and 2, none of them work/recover the cursor.

What should I do to solve/work around this issue?

Thank you so much.

I did not know the solution, but I had an idea what might be wrong.

Pass events to QTextEdit class for "further processing"

@void TextEdit::focusInEvent(QFocusEvent *e)
{
setStyleSheet("background-color: #F00");

QTextEdit::focusInEvent(e); // Notice
}

void TextEdit::focusOutEvent(QFocusEvent *e)
{
setStyleSheet("");

QTextEdit::focusOutEvent(e); // Notice
}

In my test project worked.

Is "TextEdit" a derived class from QTextEdit?

I did it in different way, by overloading the eventFilter(QObject*, QEvent).

I will try your way and I will post an update.

Thanks a lot Jake.

Yes, TextEdit is derived from QTextEdit.

If you used the eventFilter(), the procedure should be the same.
Just forward the event at the end.
@
bool TextEdit::eventFilter(QObject *obj, QEvent *event)
{
// Your code

  return QTextEdit::eventFilter(obj, event);

}

Hi Jake,

I tried using eventFilter() and pass it to QTextEdit class...didn't work.

But the solution you gave work! Overloading focusInEvent() and focusOutEvent().

Thanks a lot Jake!
